Meet Maya, and the hair routine that was working against her
Maya, 29, washed her wavy hair every single morning with the strongest “deep clean” shampoo she could find. She blasted it with a hot dryer, tied it into a tight bun for work, and brushed it fiercely while wet. By autumn her ends were splitting, her scalp felt tight and itchy, and the shower drain looked alarming.
She almost bought a costly “hair growth” supplement. Instead, a friend sent her to a dermatologist who asked three simple questions: What do you wash with? How do you style? How are you eating and sleeping? The answers explained most of it. Nothing was “wrong” with her hair. Her habits were wearing it down.
Six months of small changes later, Maya shampooed only the scalp, conditioned only the lengths, switched to a loose style, and let her hair air dry most days. Her hair was not magically transformed overnight. It simply stopped breaking.

Hair 101: what your hair is actually made of
Each strand is mostly keratin, a protein. The part you see is dead, which is why damaged hair cannot truly “heal” and only new growth is healthy. The living part is the follicle under the skin, so scalp health and body health matter as much as products.
Chapter 3
The 10 essential hair-care practices
Think of these as the foundation. Everything else in this guide builds on them.
Wash smartly
Wash according to how oily or dirty your scalp gets, not by a fixed rule. The AAD advises washing oily hair more often and chemically treated or dry hair less often.
- Wet hair fully with lukewarm water. Very hot water can irritate the scalp.
- Focus shampoo on the scalp. The lather rinsing down the lengths is usually enough.
- Massage with fingertips (not nails) for about a minute, then rinse well.
- Medicated shampoos (for dandruff) often need to stay on for several minutes. Follow the label.
Condition and moisturize
Conditioner smooths the cuticle, reduces tangles and cuts breakage. Apply it mainly to mid-lengths and ends. Fine or straight hair does well with ends only. Dry, curly or coily hair usually benefits from conditioner on the whole length, per the AAD.
- Leave it on for 1 to 3 minutes, then rinse.
- Use a leave-in or light cream on damp hair if your hair is dry.
- Use a deeper mask once a week or fortnight if needed.
Care for the scalp
Your scalp is skin. Healthy hair grows from a calm, clean, balanced scalp.
- Clean off sweat, oil and product build-up regularly.
- Treat flaking and itching early (see the dandruff section).
- Be gentle. Scratching and harsh scrubbing cause irritation.
- Protect the scalp from sunburn at the parting.
Oil and massage (optional)
Oiling is a cultural tradition in many parts of the world. Oil can reduce friction and help with dryness on the lengths. It does not make hair grow faster. A gentle massage feels relaxing and may boost comfort.
- Use a small amount, mostly on lengths and ends.
- If you are prone to dandruff or an oily scalp, keep oil off the scalp or leave it on for a short time only.
- Always wash the oil out thoroughly.
Comb and detangle gently
Wet hair is fragile. The AAD suggests a wide-tooth comb for wet hair, starting at the ends and working upward.
- Detangle with conditioner in, in sections.
- Avoid rubbing hair roughly with a towel. Squeeze or use a soft cotton T-shirt or microfibre towel.
- Tightly curled or textured hair is often easiest to detangle when wet and conditioned.
Protect from heat and tight styling
Repeated heat damages the hair structure, and damaged hair cannot be repaired, only grown out. Tight styles cause traction alopecia, a type of hair loss that can become permanent.
- Air dry when you can. If you blow dry, use low heat and keep the dryer moving, about 15 cm (6 inches) away.
- Use a heat protectant, and keep flat irons and curling tongs to occasional use.
- If your style hurts, it is too tight.
Trim regularly
Trimming does not speed up growth, but it removes split ends before they travel up the strand and cause breakage. A trim every 8 to 12 weeks suits most people, and every 12 to 16 weeks for very short, coily or low-manipulation styles.
Eat and hydrate for hair
Hair is made of protein and needs energy, iron, zinc, vitamins and fats to grow. Crash diets and big weight loss commonly trigger shedding.
- Regular meals with protein, vegetables, fruit, whole grains and healthy fats.
- Iron, vitamin D, B12 and thyroid problems are worth checking if you shed heavily.
- Avoid taking high-dose supplements without a test, since extra is not better.
Shield from sun, pollution and water
Strong UV can weaken the cuticle and fade color. Chlorine and salt water dry hair.
- Wear a hat or scarf in strong sun, and put sunscreen on the parting.
- Rinse hair before and after swimming, and wear a cap if you swim often.
- Cleanse after heavy dust, smoke or sweat.
Stay consistent
Hair is slow. Real change takes 3 to 6 months because hair grows about 1 cm a month. Build a simple routine you can keep and judge results over months, not days.

Care that fits your hair and scalp
There is no single best routine. Pick your hair pattern, scalp type and life stage below to see tailored guidance.
Quick finder
By hair pattern
Straight
Shows oil quickly because sebum slides easily down the strand. Often shiny but can look flat.
- Wash a little more often if the roots get oily.
- Condition ends only.
- Light, non-greasy styling products.
Wavy
Sits between straight and curly, and can frizz in humidity.
- Lightweight conditioner and a leave-in cream.
- Scrunch and air dry, or diffuse on low heat.
- Avoid heavy oils that flatten waves.
Curly
Curls make it harder for scalp oil to travel down, so lengths tend to be dry and prone to frizz.
- Moisturizing conditioner on the full length.
- Detangle wet, with conditioner, using fingers or a wide comb.
- Sulfate-free or gentle cleansers if your hair is dry.
Coily
Naturally the driest and most fragile pattern, since tight bends are weak points.
- Moisture first: water, leave-in, then a sealing oil or butter.
- Protective styles must be loose and rested between wears.
- Wash gently every 1 to 2 weeks, using co-wash or gentle shampoo as needed. Wear a satin bonnet or pillowcase at night.
By scalp type
Normal
Neither oily nor flaky. Wash 2 to 3 times a week with a mild shampoo.
Oily
Wash every 1 to 2 days with a gentle clarifying or balancing shampoo. Skip heavy oils on the scalp. Do not over-scrub, since that can trigger more oil.
Dry
Wash less often, use lukewarm water, and choose a hydrating shampoo. Flaking with redness may be dandruff or eczema, so check the dandruff section.
Sensitive
Choose fragrance-free, simple formulas. Patch test new products on the inner forearm for 24 to 48 hours. Avoid harsh dyes. Stop anything that stings or burns.
By age and gender
| Group | What changes | What helps |
|---|---|---|
| Children | Fine hair, sensitive scalp, tangles, head lice risk at school age. | Mild tear-free shampoo, loose styles, soft brushes. Teach gentle detangling early (AAD). |
| Teens | Hormones raise oil. Heat tools and dyes are tried for the first time. | Wash as often as needed, patch test dye, limit heat, avoid tight styles. |
| Adults | Stress, diet, postpartum and medication-related shedding. | Balanced diet, sleep, gentle routine. See a doctor for persistent shedding. |
| Pregnancy and postpartum | Hair often looks thicker in pregnancy, then sheds 2 to 4 months after birth (normal, temporary). | Reassurance, good nutrition, gentle handling. See a doctor if shedding lasts beyond a year. |
| Menopause and older age | Hair becomes thinner, drier, and may turn grey or white. Scalp oil falls. | Richer conditioner, less washing, thyroid and iron checks if shedding is heavy, volumizing cuts. |
| Men | Pattern hair loss (hairline and crown), beard care and razor irritation. | Early review for thinning, dandruff control, gentle shaving, beard cleansing (AAD has beard guidance). |
| Women | Diffuse thinning at the parting, hormonal change, styling stress. | Checks for iron, thyroid and hormones. Loose styles. Minoxidil may be an option after medical advice. |
| Trans and non-binary people | Hormone therapy may change oil, texture and shedding or thinning patterns. | Choose care by hair and scalp type, and discuss changes with your clinician. |
| Head coverings (hijab, turban, wigs) | Friction, sweat and tension can irritate the scalp and hairline. | Breathable fabrics, no tight pulling, a clean cloth liner, and scalp rest time. The AAD notes covers can contribute to traction alopecia if tight. |

Common hair problems: causes, prevention and treatment
Tap a problem to see what usually causes it and what to do. Evidence is drawn from the AAD, NHS, Mayo Clinic and Harvard Health.
What is going on
Losing 50 to 100 hairs a day is normal. Hair loss becomes a concern when shedding is much heavier, hair comes out in clumps, parts widen, or bald patches appear.
Common causes
- Telogen effluvium: sudden shedding 2 to 4 months after illness, fever, surgery, childbirth, major stress or crash dieting. It usually settles within 6 to 9 months (Harvard Health).
- Pattern hair loss: inherited, gradual, and usually permanent without treatment (NHS).
- Alopecia areata: autoimmune, round smooth patches.
- Iron deficiency, thyroid disease, some medicines.
- Traction: tight hairstyles over years.
What to do
- Eat enough protein, iron and calories. Do not crash diet.
- Manage stress and sleep, since they affect the cycle.
- Loosen styles, and avoid harsh chemical treatments.
- Ask a GP or dermatologist about blood tests (iron, ferritin, thyroid, vitamin D, B12) if shedding lasts over 3 months.
- Treatments for pattern loss: minoxidil (men and women) and finasteride (men only; women should not use it per the NHS). These work only while used and are not guaranteed for everyone.
- No treatment has been proven to speed up active telogen effluvium. Fix the trigger and be patient.
What is going on
Dandruff is a mild form of seborrheic dermatitis. It is common, not contagious and not a sign of poor hygiene (Mayo Clinic).
Causes
- Oily, irritated skin and a yeast-like fungus (Malassezia) that feeds on scalp oil.
- Dry skin, cold dry weather and stress.
- Reaction to hair products (contact dermatitis).
- Other conditions such as eczema and psoriasis.
What to do
- Start with regular washing using a gentle shampoo.
- Then try a medicated shampoo. Common active ingredients include zinc pyrithione, selenium sulfide, ketoconazole, salicylic acid and coal tar.
- Leave it on for about 5 minutes, as per the label (Mayo Clinic Minute).
- If it stops working, rotate between up to three shampoos with different actives (Mayo Clinic).
- Stop a product that stings or causes a rash. Seek urgent help for swelling or trouble breathing.
- See a doctor if there is no improvement after a few weeks, or if the scalp is red, painful, crusted or oozing.
What is going on
Dry, brittle hair has a roughened cuticle that loses moisture and snaps easily.
Causes
- Heat styling, bleaching, perming, relaxing and frequent colouring.
- Over-washing with harsh cleansers, hot water.
- Sun, chlorine, salt water, dry or windy climate.
- Low protein or iron intake, and thyroid issues.
What to do
- Wash less often, and condition every time.
- Weekly deep conditioning mask.
- Air dry or use low heat with a protectant.
- Space chemical treatments many weeks apart, and avoid doing several in one session.
- Trim damaged ends. Heat-damaged hair cannot be repaired and must grow out (AAD).
What is going on
Oil glands produce sebum to protect the scalp. Some people simply make more, especially during puberty, hormone change and humid weather.
Causes
- Genetics and hormones.
- Infrequent washing, or heavy leave-in products and oils at the roots.
- Seborrheic dermatitis.
- Over-washing with harsh products can sometimes make the scalp feel greasier again.
What to do
- Wash as often as the scalp needs. The AAD says oily hair should be washed more often.
- Use a gentle, balancing shampoo, and a clarifying one every 1 to 2 weeks.
- Condition only the ends.
- Touch and brush your hair less, since this spreads oil.
- Persistent greasiness with flakes may need a dandruff shampoo.
What is going on
Frizz happens when the cuticle is raised and hair absorbs humidity. Split ends are the strand’s end fraying after wear and tear.
Causes
- Dryness, heat, rough towel drying and friction.
- Chemical treatments and sun.
- Natural curl pattern and humidity.
What to do
- Condition well, and use a leave-in or light serum on damp hair.
- Do not brush curls dry. Detangle wet with conditioner.
- Sleep on silk or satin, or in a bonnet.
- Trim every 8 to 12 weeks. No product can glue a split end back for good, since products only smooth it temporarily.
What is going on
Breakage is hair snapping along the strand, which creates short, uneven pieces. Thinning is fewer or finer hairs growing from the follicle. They need different responses.
Causes
- Breakage: heat, bleach, tight styles, rough brushing, brittle lengths.
- Thinning: pattern hair loss, hormones, nutrition, thyroid, age, medicines, scarring conditions.
What to do
- Reduce tension and heat. Pain from a hairstyle signals it is too tight.
- Look for short broken hairs around the hairline and temples, an early sign of traction alopecia.
- Stop tight styles early, because long-term traction can cause permanent loss (AAD).
- Get thinning that is progressive, patchy, or scalp-related checked early. Early treatment keeps more hair.
What is going on
Hair turns grey when pigment cells in the follicle slow down. Timing is strongly genetic and varies across ethnic groups. Premature greying is commonly defined as starting before about 20 in people of European descent, before 25 in Asian populations and before 30 in people of African descent.
Possible contributors
- Family history, which is the main factor.
- Smoking.
- Vitamin B12 deficiency, thyroid disease and some autoimmune conditions.
What to do
- Genetic greying cannot be reversed by oils, diets or supplements. Be wary of claims that say otherwise.
- Stop smoking, eat a balanced diet, and get a blood test if greying is sudden or comes with fatigue or other symptoms.
- Colour is a safe cosmetic choice if patch tested. Greying is not a health problem on its own, and many people embrace it.

Routines you can actually keep
Adjust the frequency to your hair type. The goal is simple, repeatable and kind to your hair.
Morning (3 to 5 min)
- Gently detangle dry hair from the ends up (curly hair: use damp fingers).
- Smooth a pea-sized amount of leave-in or serum on the ends if dry.
- Style loosely. Use no heat if you can.
- Sunscreen on the parting, and a hat or scarf in strong sun.
Evening and bedtime
- Detangle gently, and remove tight bands.
- Loose braid or high loose bun (a “pineapple” for curls).
- Satin or silk pillowcase, or bonnet.
- Never sleep with wet hair tied tightly.
Weekly
- Wash 1 to 4 times, depending on type.
- One deep conditioning mask.
- One gentle scalp massage session (3 to 5 min).
- Clean brushes and combs.
- Change pillowcase.
Monthly
- Clarify once if there is product build-up.
- Check your scalp for new flakes, redness or patches.
- Photograph your parting to track changes.
- Book a trim every 8 to 12 weeks.

Natural remedies: what helps, what is hype
“Natural” does not automatically mean safe or effective. Here is an honest scorecard. Always patch test, since plant ingredients are a common cause of contact allergy.
| Ingredient | Evidence level | Possible benefit | How to use and cautions |
|---|---|---|---|
| Coconut oil | Some evidence | Lab studies suggest it can reduce protein loss in hair when used before washing. | Apply to lengths 30 minutes before shampooing. Can feel heavy on fine hair, and can worsen scalp flaking in some people. |
| Argan and jojoba oil | Limited | Light sheen, softer ends, less friction. | A few drops on ends. Not proven to grow hair. |
| Aloe vera gel | Limited | Soothing and conditioning feel. | Use pure gel, patch test, rinse after 20 to 30 minutes. |
| Rosemary oil (diluted) | Early research | One small trial reported results similar to 2% minoxidil at 6 months. More research is needed. | Dilute well in a carrier oil. Never apply undiluted essential oil. Avoid in pregnancy without advice. Stop if irritated. |
| Tea tree oil (diluted) | Limited | Mild antifungal effect for dandruff in small studies, and the Mayo Clinic lists tea tree as an option with limited proof. | Use shampoos with a low, labelled concentration. Never use neat on the scalp, because it can cause allergic reactions. |
| Onion juice, fenugreek, curry leaf, hibiscus | Weak | Traditional use. Evidence is weak or from small studies. | Can be smelly or irritating. Not a replacement for medical treatment. |
| Egg, yogurt, banana, honey masks | Mostly anecdotal | Temporary softness and shine. | Rinse with cool water (hot water can cook egg). Allergy risk. Does not rebuild damaged hair. |
| Apple cider vinegar rinse | Limited | Can smooth the cuticle for some people. | Dilute (1 tablespoon in 1 cup of water), and skip it on a sensitive or irritated scalp. |
| Lemon juice, baking soda, neat essential oils, kerosene, bleach | Avoid | None proven. | Can burn, dry out or inflame the scalp, and cause chemical damage or sun sensitivity. |
Simple pre-wash oil treatment
- Warm 1 to 2 teaspoons of oil in your palms (not hot).
- Smooth through mid-lengths and ends.
- Leave 30 to 60 minutes.
- Shampoo twice if needed to remove it.
Soothing aloe and water mist
- Mix 1 tablespoon pure aloe gel with 1 cup of clean water.
- Store in the fridge for up to 3 days.
- Lightly mist ends of damp hair.
- Discard if smell or colour changes.
Gentle scalp massage
- Use fingertips with light to medium pressure.
- Make small circles from the front hairline to the nape.
- Spend 3 to 5 minutes. It should never hurt.
- Skip it on broken, sunburned or inflamed skin.

Choosing products without wasting money
Price does not equal quality. Match the product to your scalp and hair, read the ingredient list, and change one product at a time.
| Product | Pick this if you have | Helpful ingredients | Be careful with |
|---|---|---|---|
| Shampoo | Oily: balancing or clarifying. Dry or curly: hydrating, gentle. Flaky: medicated. | Mild surfactants, glycerin, panthenol, zinc pyrithione, ketoconazole, selenium sulfide, salicylic acid (for flakes). | Strong fragrance, high alcohol content for dry hair, and daily clarifying use. |
| Conditioner | All hair types. Fine hair: lightweight. Thick or coily: rich. | Glycerin, fatty alcohols (cetyl, cetearyl), shea butter, ceramides, amino acids. | Heavy butters at the roots of fine hair. |
| Hair oil | Dry ends, frizz, coily hair. | Coconut, argan, jojoba, almond, sunflower. | Oil on a dandruff-prone scalp, and nut oil if allergic. |
| Serum and leave-in | Frizz, split-end look, heat styling. | Light silicones (dimethicone) for smoothness, plant oils, humectants. | Silicone build-up on fine hair. Clarify monthly if needed. |
| Hair mask | Damaged, coloured or very dry hair. | Keratin or amino acids, ceramides, plant oils. | Using protein masks too often, which can make hair stiff and brittle. |
| Styling products | Hold or definition. | Water-based gels and creams, heat protectants. | Alcohol-heavy sprays on dry hair, and sleeping in product. |
Often helpful
- Glycerin, panthenol, aloe
- Ceramides and fatty alcohols
- Zinc pyrithione, ketoconazole for flaking
- UV filters in leave-ins if outdoors much
Possible irritants
- Fragrance and essential oils
- Preservative allergens (such as methylisothiazolinone)
- Hair dye ingredient PPD (a common allergen)
- Strong sulfates for very dry or sensitive scalps
Skip these
- Formaldehyde-releasing straighteners
- Home bleaching without a patch test
- “Miracle” hair-growth supplements with big claims
- Unregulated products with no ingredient list

Myths vs facts
Chapter 10
When to see a doctor or dermatologist
Most hair changes are harmless, but some signal a treatable medical or scalp condition. Early treatment protects more hair, especially for scarring types.
Warning signs
- Sudden or heavy shedding, or clumps of hair.
- Round or patchy bald areas.
- Receding hairline or widening parting.
- Scalp pain, burning, redness, pus, crusts or scaly patches.
- Itch that disturbs sleep, or flaking that does not respond to shampoo after a few weeks.
- Smooth, shiny scalp areas where hair no longer grows (possible scarring).
- Hair changes with fatigue, weight change, heavy periods, cold intolerance or other symptoms.
- Hair loss in children.
- Distress about your hair that affects daily life. Support is available.
What a clinician may do
- Examine the scalp and hair, and ask about history, diet, stress and medicines.
- Run blood tests (such as iron, thyroid, vitamin D, B12).
- Perform a gentle pull test, dermoscopy or, occasionally, a scalp biopsy.
- Treat with prescription or evidence-based options such as minoxidil, finasteride (men), steroid injections or creams, antifungal treatments, light therapy or other medicines depending on the diagnosis. Some options may not be available free on the NHS.
Chapter 11
Beyond the bathroom: nutrition and lifestyle
Eat for your follicles
- Protein: eggs, fish, pulses, tofu, dairy, nuts.
- Iron: lentils, leafy greens, meat, fortified foods (pair with vitamin C).
- Zinc: seeds, whole grains, legumes.
- Healthy fats: oily fish, nuts, seeds.
- B vitamins: a varied diet (vegans need a reliable B12 source).
Habits that help
- Sleep 7 to 9 hours.
- Stay hydrated.
- Stay active, and use stress tools such as walks or breathing.
- Do not smoke.
- Limit alcohol.
Budget and climate tips
- A basic gentle shampoo plus conditioner is enough.
- Use cotton T-shirt towels and old satin scarves for free upgrades.
- Humid climates: lighter products, anti-frizz leave-in.
- Dry or cold climates: richer conditioner, humidifier, covered hair outdoors.
- Hard water: occasional clarifying rinse or filter shower head.
