Reetha and Shikakai: The Old Shampoo, How to Use It, and What It Won't Do

Short answer: reetha (soapnut) and shikakai are the two plants behind the hair wash that came before shampoo. Both contain saponins - natural surfactants that foam in water and lift oil, dust and product out of the hair. They clean genuinely well, and for a lot of people they are a perfectly good alternative to a bottle. What they do not do is turn hair black, thicken it, or regrow it, and they are not automatically gentler than shampoo: a saponin wash can leave long hair dry, rough and hard to comb, especially in hard water.

This is the long version of our reetha and shikakai reel: which pod does what, how to make the wash, how often to use it, and the claims in the family story that do not survive a closer look.

Two different plants, one wash

They are not the same thing, which is why the two are usually used together rather than interchangeably.

Reetha is the dried fruit of Sapindus mukorossi, the soapnut tree. The soap is in the papery brown shell; the black seed inside contributes nothing and is usually removed. Reetha is high in saponins, which is why it foams the most and lifts oil the hardest. It is the stronger degreaser of the two.

Shikakai is the dried pod of Acacia concinna, a thorny shrub across South Asia. It also contains saponins, but less, and it is mildly acidic. In practice that means less foam, less stripping, and hair that feels softer afterwards than reetha alone. For hair that is dry or washed often, shikakai is usually the better single choice.

Amla is the third member of the classic trio. It has almost no saponin of its own; it is there for the acidic, conditioning side and the tradition, not to make lather.

Why they lather without a bottle

Saponins are molecules with a water-loving head and an oil-loving tail. In water they gather at the surface and at the boundary between water and oil, which lets water grab oil and rinse it away. That is the same basic job a synthetic surfactant does in shampoo - the difference is that saponins are milder, foam less in hard water, and come with no conditioning agents attached.

That last point explains almost every complaint people have about the traditional wash. Shampoo has polymers, silicones and conditioning agents mixed in to make wet hair feel slippery. A reetha wash has none of that, so wet hair feels squeaky and grabs itself. It is not damaged - it is simply uncoated.

What it can and cannot do

It can	It cannot
Lift oil, dust and everyday product buildup	Turn grey or brown hair black
Replace shampoo for people who want no sulphates	Grow new hair or stop hereditary hair loss
Clean without the heavy coating of a silicone shampoo	Condition or detangle long, dry or curly hair on its own
Cost very little, and store for months dry	Remove heavy silicones or wax in one wash

Shine after a reetha wash is real, but it comes from hair being clean and slightly acidic, which lets the cuticle lie flat. It is not a change in hair colour or thickness, and it washes out the moment oil or product goes back on.

The recipe

What you need

• 8 to 10 dried reetha shells (about 25g), seed removed
• 3 to 4 dried shikakai pods, broken up
• 500ml water
• A pot with a lid, and a muslin or thin cotton cloth for straining

Method

1. Soak overnight. Put the reetha shells and broken shikakai pods in the water and leave them covered for at least 8 hours. The water goes tea-coloured and slightly slippery.
2. Simmer for 15 to 20 minutes. Bring the same water and pods to a low simmer, lid on. Do not boil hard; you are extracting, not cooking it down.
3. Cool, then mash the pods with the back of a spoon to get the last of the saponin out, and simmer another 5 minutes if you want a stronger wash.
4. Strain through cloth. Squeeze the pulp dry. What comes through should look like weak tea.
5. Use it as shampoo. Wet the hair, pour the liquid over the scalp, massage for 2 to 3 minutes, then rinse until the water runs clear.

That batch is enough for two or three washes. Keep it covered in the fridge and use it within three or four days - it has no preservative in it, so if it smells sour or grows anything on top, throw it out.

Making it easier to live with

• Add a spoon of methi (fenugreek) powder to the soak. It leaves a little mucilage in the liquid, which gives slip and makes wet hair easier to comb.
• Use filtered water for the final rinse if your tap water is hard. Saponins and the calcium in hard water form a scum that leaves hair dull; this is the single most common reason people give up on reetha.
• Oil before you wash. A light pre-wash oil, 30 minutes, gives the saponin something to work on and leaves the lengths less stripped.

How often, and who should not use it

Once or twice a week is the useful rhythm for most people: the traditional wash as a deeper clean, a gentle sulphate-free shampoo in between. Using it daily leaves most long hair rough and tangly, because there is nothing in it to replace the oils it lifts.

• Skip it on freshly coloured hair. Saponins clean strongly and will speed up colour fade. Wait a couple of weeks, or keep it off the coloured lengths.
• Skip it if your hair is very dry, bleached or chemically straightened. It cleans well and conditions not at all; these hair types need the opposite balance.
• Be careful with a flaky or inflamed scalp. A reetha wash is not a dandruff treatment, and the residue can make an already irritated scalp worse.
• Patch test if you have sensitive skin. Reetha and shikakai are botanical extracts and can cause contact reactions in a small number of people.

The part of the story that is not true

The reel repeats the family claim: strong, black, shiny hair. Two of those three hold up and one does not.

Clean hair looks shinier, because light reflects off a smooth, uncoated cuticle - and a mildly acidic wash helps the cuticle sit flat. That part is real.

Hair feels stronger when it is not weighed down by oil and product, and a wash that removes buildup makes hair behave better. That is a real, if modest, effect.

Hair does not turn black. There is no evidence that reetha, shikakai or amla darken hair or reverse greying; nothing applied to the outside of a hair shaft changes its pigment. Grey hair is a follicle decision, not a surface one. If a product promises otherwise, it is selling the story rather than the chemistry.

Using it in a modern routine

The honest place for the traditional wash is once a week, as the deep clean - and a shampoo that already contains these three herbs for the rest of the week. That is what most of our customers end up doing: the ritual on a Sunday, a bottle on the other five days.

FAQ

Can I mix amla, shikakai and reetha together? amla shikakai reetha ye teen cheezein milakar bohat acha kaam karti hain, bohat purana nuska hai

Yes - that is the classic trio, and it is what most traditional washes use. Take 8 to 10 reetha shells, 3 to 4 shikakai pods and 1 tablespoon of amla powder, soak overnight, simmer for 15 to 20 minutes, strain, and use it as a wash. The reetha does the cleaning, the shikakai softens it, and the amla adds the acidic, conditioning side.

My mother used it too - why did it work so well for her generation? dadi nahi, meri ammi bhi hamare baalon mein lagati thi

Partly the hair, partly the routine. Hair was usually kept shorter, oiled before washing, and never exposed to the styling products and silicone shampoos that build up on hair today. Water supplies were also often softer than the hard, mineral-heavy water most Pakistani cities get now. The same recipe on long, colour-treated hair in hard water can feel rough - which is why the final-rinse water matters as much as the pods.

Which is better, reetha or shikakai?

Reetha cleans harder and foams more; shikakai is milder and leaves hair softer. For an oily scalp or a weekly deep clean, reetha. For dry hair or more frequent washing, shikakai. Most traditional recipes use both, which balances the two.

How many reetha nuts should I use?

Eight to ten shells, with the black seed removed, for about 500ml of water. That makes two or three washes. Using more does not clean better - it just leaves the hair rougher.

How long should I soak reetha and shikakai? reetha shikakai ko kitni dair bhigo kar rakhna hai?

Overnight, at least 8 hours, is the reliable way. If you are making it the same day, soak the pods in hot (not boiling) water for 2 hours, then simmer for 15 to 20 minutes.

Why does my hair feel rough and tangly after a reetha wash?

Because the wash lifts oil and leaves nothing behind to replace it. Shampoo contains conditioning agents that coat the strand; a saponin wash does not. Oil lightly before washing, add a spoon of methi to the batch, use filtered water for the final rinse, and finish with a conditioner on the lengths.

Does it lather like shampoo?

Less, and less still in hard water. Saponins foam, but not as much as synthetic surfactants, and calcium in hard water suppresses the foam. A modest lather is normal and does not mean it is not cleaning.

Can I use reetha and shikakai on coloured hair?

Carefully. Saponins clean strongly enough to speed up colour fade. Keep the wash off freshly coloured hair for a couple of weeks and off the coloured lengths afterwards, or use a sulphate-free shampoo instead.

Does reetha make hair black?

No. There is no evidence that reetha, shikakai or amla darken hair or reverse greying - pigment is produced inside the follicle, and nothing you rinse through the hair changes it. What these herbs do is clean hair well, which makes its natural colour look clearer and shinier.
