Hair Care Basics: Shampoo, Conditioner and Oiling in India

For most people in India, healthy hair care means washing as often as your scalp gets oily or sweaty, applying shampoo to the scalp and conditioner to the lengths, and handling wet hair gently. Oiling can protect the hair shaft and make combing easier, but it is a conditioner for the hair, not a treatment for hair fall, and oil left on the scalp may make dandruff worse for some people.

Hair care advice in Indian homes is full of strong opinions. Many of us grew up with weekly champi, warnings that daily shampoo will make hair fall, and the belief that a flaky scalp needs more oil. This guide looks at what the evidence actually says and how to adapt it to our heat, humidity and pollution.

How often should you wash your hair in India?

The American Academy of Dermatology (AAD) advises washing your hair based on how often it gets dirty or oily, rather than following a fixed rule.

• Oily scalp, straight or fine hair: you may need to shampoo every day.
• Dry, curly, coarse or thick hair: shampoo when needed. The AAD notes this can be as infrequent as once every 2 to 3 weeks for some very dry or textured hair types.

In Indian summers and the monsoon, sweat, sebum, dust and pollution build up quickly, so many people with oily scalps feel and look better washing daily or every other day. People who exercise, travel on two wheelers or wear helmets often need to wash more frequently too.

The AAD also points out that flakes in the hair can come from not shampooing often enough. Waiting a week between washes so that oil can “nourish” the scalp is not supported by evidence, and the NHS notes that while dandruff is not caused by poor hygiene, it can be more obvious if you do not wash your hair regularly.

A simple washing guide

Your hair and scalp	Typical washing frequency	Notes
Oily scalp, straight or fine hair	Daily or alternate days	Use a mild shampoo, focus on the scalp
Normal scalp	Two to three times a week	Wash more often in humid months or after sweating
Dry, curly, coily or thick hair	Once a week or as needed	Condition the full length, detangle gently
Dandruff or seborrhoeic dermatitis	As advised by your dermatologist	Medicated shampoo usually needs regular use

How should you shampoo your hair?

A review of hair cosmetics in the International Journal of Trichology explains that shampoo should target the scalp more than the hair. The AAD gives the same advice.

1. Wet your hair fully with lukewarm water.
2. Apply a small amount of shampoo to the scalp, section by section, rather than piling it on top of your head.
3. Massage the scalp gently with your fingertips, not your nails.
4. Let the lather run through the lengths as you rinse. You do not need to scrub the ends.
5. Rinse thoroughly.

Piling shampoo on the top of the head and rubbing the lengths together increases friction and tangling, according to the same review.

Does daily shampoo cause hair fall?

Many people notice hair in the drain and stop washing, but shedding a number of hairs each day is normal, and washing simply removes hairs that were already loose. If you are losing clumps of hair or seeing a widening parting, the cause is usually something else, such as hormonal changes, thyroid problems, iron deficiency or a recent illness. Our guides to hair fall in women and hair fall linked to thyroid, iron and vitamins explain the common causes.

Do you really need conditioner?

Conditioner reduces friction, detangles, controls frizz and makes hair easier to comb. The hair cosmetics review explains that conditioners work by neutralising the negative electrical charge on the hair surface and lubricating the cuticle. This matters because combing dry, tangled hair causes breakage.

How to use it:

• Fine or straight hair: apply conditioner to the ends only, as the AAD suggests.
• Dry or curly hair: apply it along the full length.
• Avoid the scalp: the review advises applying conditioner to the lengths, avoiding the scalp, and rinsing it out completely.

If you use a medicated anti-dandruff shampoo, conditioning becomes more important, because these shampoos can make hair harder to comb.

Is hair oiling good for your hair?

Oiling is one of the most loved hair rituals in India, and there is some science behind part of it. But the benefits are about the hair shaft, the part of the hair that has already grown out, rather than the root.

What the research shows

The hair cosmetics review notes that relatively few studies have looked at oils on human hair. Those that exist suggest:

• Some oils penetrate the hair. Laboratory studies found that coconut oil can diffuse into the hair fibre, while mineral oil stays on the surface.
• Oils reduce water uptake. Both coconut oil and mineral oil reduced how much water hair absorbs. This may lower hygral fatigue, the repeated swelling and drying that weakens hair over time.
• Oils may protect against shampoo damage. By filling gaps between cuticle cells, some oils can limit how much harsh cleansing agents penetrate.
• Oils lubricate. Regular oiling can make hair smoother and easier to comb, which reduces breakage.

What oiling cannot do

• Oil does not reach or feed the hair root in any meaningful way, so it is not a treatment for hair fall, thinning or baldness.
• There is no good evidence that any particular oil, onion oil, or herbal blend makes hair grow faster or thicker.
• Oil does not cure dandruff, and it may worsen it in some people (see below).

How to oil sensibly

• Focus on the lengths and ends, where hair is oldest and most damaged.
• Use a small amount. The review notes that thick films of oil can leave hair looking heavy and greasy, and a thin layer is preferable.
• Wash it out with your usual shampoo. Leaving heavy oil on the scalp for days in humid weather traps sweat and dirt.
• Pick an oil you like. Plain coconut oil has the most research behind it, but you do not need expensive products.

Can oiling make dandruff worse?

It can, for some people. Dandruff is a mild form of seborrhoeic dermatitis, a condition linked to Malassezia, a yeast that lives on normal skin and feeds on oils. A 2023 letter in the journal Skin Appendage Disorders explained that this yeast is lipid dependent, and that heavy use of scalp oils combined with infrequent washing may increase yeast numbers and the risk of seborrhoeic dermatitis. The authors also noted that seborrhoeic dermatitis is often mistaken for a “dry scalp” and treated with more oil.

This is a very common pattern in India: the scalp flakes, the family advises more oil, and the flakes get worse. If you have dandruff, try:

• Keeping oil off the scalp and on the lengths only
• Using an anti-dandruff shampoo. The AAD lists ingredients such as zinc pyrithione, salicylic acid, selenium sulfide, ketoconazole and coal tar
• Leaving medicated shampoo on the scalp for the time the label advises before rinsing

Our guides to dandruff and seborrhoeic dermatitis and dry scalp versus dandruff explain how to tell them apart.

What other daily habits protect your hair?

The AAD recommends:

• Detangle gently. Wet hair is fragile, so use a wide tooth comb instead of a brush.
• Blot, do not rub. Wrap your hair in a towel or cotton T shirt to absorb water.
• Limit heat. Use straighteners, curling irons and blow dryers less often, on low or medium settings, with a heat protectant.
• Choose products for your hair type.

Indian specific tips:

• Tie hair loosely. Tight braids and buns pulled every day can strain the hairline.
• Wash after swimming or heavy sweating, and in the monsoon dry the scalp properly. Our guide to monsoon hair care has more detail.
• Be careful with hair dye and henna mixes. Allergic reactions to dye are common. See our article on hair dye allergy.

When to see a dermatologist

See a dermatologist if:

• You are losing more hair than usual for more than a few weeks, or notice thinning or patches
• Dandruff has not improved after using an anti-dandruff shampoo for about 4 weeks, which is the point at which the NHS advises seeing a doctor
• Your scalp is red, swollen, painful or very itchy, or you have flaky patches on your face or body
• You have scaly patches with hair loss, especially in a child, which may be a fungal infection
• Your hair has become very brittle or breaks easily despite gentle care

Good hair care is mostly about consistency and gentleness, not expensive products. If you are unsure what is causing a scalp or hair problem, Dr. Maria offers online consultations to help work out the cause and a routine that suits your hair.
