How to Wash Your Hair with Aritha (Reetha) Powder

Aritha, also sold as reetha or soapnut, makes a fresh botanical hair wash with warm water. How much to use for your hair length, how long to leave it, what to mix in, and how often.

The short answer: mix about 10 g of aritha powder for short hair, up to about 40 g for long or thick hair, with warm water to a smooth, pourable, cream-like wash. Let it hydrate for 5–10 minutes, apply it to wet hair with most of it at the scalp, leave it 3–5 minutes, then rinse very thoroughly. Allow about 15 minutes in all, and use it up to twice a week.

Aritha, also sold as reetha or soapnut, is a single-ingredient cleansing powder you mix fresh, so this page covers what to expect as well as what to do. For what the powder is, see the aritha powder page.

What you need

Aritha powder, comfortably warm water, a bowl and something to stir with. Kitchen scales help the first few times: the right amount covers your scalp rather than making a thick layer.

Hair length Spierb Aritha Powder
Short About 10 g
Medium Between the two, adjusted to coverage
Long or thick Up to about 40 g

Before you start

Patch test 24–48 hours before your first wash, using the mixture you plan to use. Reetha wash water stings the eyes strongly, so keep it away from your face, tilt your head back while rinsing, and if any gets in, rinse promptly with plenty of clean water without rubbing.

Check your scalp is in normal condition before you start. Don't use aritha on a scalp that is broken, grazed, weeping or significantly inflamed. It is for hair and scalp only, and never for eating or drinking.

Pour and mix gently rather than whisking dry powder from a height, and detangle dry hair first: both make the wash easier.

How to use aritha powder for a hair wash

Make a thin, pourable wash, work it into a wet scalp, keep the contact short and rinse it out completely. These are the standard Spierb directions.

  1. Weigh out about 10 g of aritha powder for short hair, up to about 40 g for long or thick hair.
  2. Add comfortably warm water gradually and mix to a smooth, pourable, cream-like wash. It should be thinner than a hair mask.
  3. Leave it to hydrate for 5–10 minutes, then stir again.
  4. Wet your hair and scalp thoroughly.
  5. Apply to the scalp and roots first, massaging gently with your fingertips. Smooth only a light amount through the lengths.
  6. Leave it on for 3–5 minutes. Don't let it dry on the hair.
  7. Rinse very thoroughly, until the hair no longer feels gritty.
  8. Use conditioner on the lengths if they need it.

How do I make reetha shampoo at home?

The wash above is homemade reetha shampoo: powder and warm water, mixed fresh. There is nothing to boil or bottle. Mix only what you need, because a water-based botanical mixture isn't preserved and doesn't keep like the dry powder.

If you prefer fewer plant particles, make "reetha water": stir the powder into warm water, let it hydrate, agitate it well and strain it through muslin or fine mesh before applying. It is easier to rinse out, and still a fresh preparation.

What can I mix with aritha powder?

Reetha and shikakai are the classic pair: 1 tablespoon of each. Mix the powders, add warm water gradually to a thin, pourable wash, hydrate 10–15 minutes, apply to wet hair, massage 60–90 seconds, leave 3–5 minutes and rinse very thoroughly. The same method and ratio work for reetha with amla, bhringraj, brahmi or Aloe Vera Powder.

The classic three-powder wash is 1 tablespoon each of amla, reetha and shikakai; add bhringraj for the four-powder version, which has its own page. Reetha stays the cleanser in every blend, so the wash stays short. Neem is a scalp mask before washing, not a wash ingredient.

Rinsing and aftercare

Rinse for longer than feels necessary, until no grit remains at the nape or behind the ears. Leftover plant particles are the commonest reason clean hair feels rough afterwards.

Use your usual conditioner on the mid-lengths and ends if they want slip. Squeeze water out with a towel rather than rubbing, and judge the result once your hair is dry.

How often, and how to adjust it

Use aritha up to twice a week. Oily, resilient hair is often happy at twice a week; dry or porous lengths usually prefer once.

  • Dry, porous or curly hair: use less powder and more water, keep the wash at the scalp and let the diluted runoff clean the lengths.
  • Oily roots: keep the mixture concentrated at the scalp. If oil remains, a second brief wash beats leaving the first one on longer.
  • In a blend: reduce the reetha proportion before extending the contact time.

What to expect

Expect a tan-brown slurry, light and variable foam, and roots that feel lighter once the hair is dry. The powder disperses rather than dissolving, so sediment in the bowl is normal, and foam depends on the strength of the mix, how much you agitate it, how oily the hair was and your water. Low foam doesn't mean poor cleansing, and it usually takes two or three washes to find the dilution that suits you.

Common mistakes and quick fixes

  • Adding powder to chase foam. Judge the wash by how the roots feel after rinsing, not by bubbles.
  • Mixing it too thick. A dense paste is hard to spread and harder to rinse. Add water until it pours.
  • Leaving it on like a mask. It is a cleanser: 3–5 minutes is the whole contact time.
  • Coating the lengths. Keep the mixture at the scalp and let the rinse clean the ends.
  • Rushing the rinse. Gritty, rough hair is usually leftover powder.
  • Dry or tangled afterwards. Dilute more, shorten the contact, condition the lengths, and see reetha side effects.

Can I use reetha powder instead of shampoo?

Yes, as a fresh botanical wash, as long as you expect a powder you mix rather than a bottled formula. Many people use reetha in place of shampoo; others alternate with a mild shampoo. Both are reasonable.

What changes is the experience: a few minutes of mixing, a lighter foam and a wash strength you adjust yourself. Heavy waxes, silicone-rich styling products or a thick pre-wash oiling may still need a second wash or a conventional shampoo.

Frequently Asked Questions

Can I use reetha powder daily?

No. Use it up to twice a week. More often tends to leave hair squeaky, rough or tangled; if that happens even at twice a week, dilute the wash or drop to once a week.

Is soapnut better than shampoo?

Neither wins for everyone. Reetha is a single botanical mixed fresh, with variable foam and a strength you control. Shampoo is a finished formula that behaves the same every time and can be more convenient for heavy styling products.

Can reetha be used to remove dandruff?

A reetha wash lifts excess oil, ordinary residue and loose flakes, so a flaky, oily scalp can look and feel cleaner afterwards. Flaking that keeps coming back is more than loose surface debris and has its own causes.

How many washes do soap nuts last?

That figure belongs to whole shells, which can sometimes be soaked more than once until they are spent. Powder is different: it disperses through the wash and is mixed fresh each time, so measure by your hair length instead.

What is no poo?

"No poo" means washing hair without conventional shampoo. Using reetha is one version of it. It is still cleansing, because the saponins are surface-active; the difference is the format rather than the absence of a cleanser.

What is the healthiest way to wash my hair?

Use enough cleansing to remove oil and residue while keeping the scalp comfortable and the lengths manageable. With reetha, that usually means a well-diluted scalp-focused wash, a thorough rinse and conditioner when the ends want it.
