Reetha (Aritha) vs Shikakai: Which Hair Wash Powder, and Can You Mix Them?
Reetha (Aritha) is the stronger hair wash and Shikakai the gentler one: choose Reetha for oily or product-coated roots and Shikakai for regular washing or dry, curly hair. Or mix 1 tablespoon of each into one thin wash.
The short answer: Reetha (Aritha) is the stronger hair wash and Shikakai the gentler one. Choose Reetha if your roots get oily quickly or carry oil and styling product, and Shikakai for regular washing, or if your hair is dry, curly or tangles easily. You don't have to pick: 1 tablespoon of each makes an established wash of its own.
Both are single-ingredient powders you mix with warm water yourself, and both clean the same way: natural saponins in the fruit help water lift oil and everyday residue so the rinse carries them away. Neither is a conditioner, a hair dye or a treatment. Reetha is the dried fruit of Sapindus mukorossi, the soapnut tree; Shikakai is the dried fruit pod of Acacia concinna.
What's the difference between Shikakai and Reetha?
| Reetha (Aritha) | Shikakai | |
|---|---|---|
| Plant | Soapnut fruit, Sapindus mukorossi | Fruit pod of Acacia concinna |
| Cleanse | The stronger of the two | The gentler of the two, with more slip |
| Lather | Light, and usually more than Shikakai | Low |
| How much | About 10 g for short hair, up to about 40 g for long or thick hair | 10–15 g short, 20–25 g shoulder-length, about 30 g or more for very long or thick hair |
| Method | Thin, pourable wash; stand 5–10 minutes; massage gently; 3–5 minutes on wet scalp | Thin, pourable wash; stand 5–10 minutes; massage 60–90 seconds; 3–5 minutes on wet scalp |
| How often | Up to twice a week | Up to twice a week |
| Eyes | Stings strongly | Stings; keep it out of your eyes |
The routine is the same shape for both: a thin wash rather than a paste, a few minutes to stand, wet hair, the scalp first, a short contact time and a thorough rinse. The rinse is the step people cut short, and it decides whether hair feels clean or gritty afterwards.
Does Reetha (Aritha) lather more than Shikakai?
Usually a little, because Reetha is the more saponin-led of the two, but neither foams like a bottled shampoo. Shikakai's low lather is normal. How much foam you see depends on how strong the mix is, how oily your hair was, your water and how much you massage, so judge the wash by clean roots and a comfortable scalp, not by bubbles.
Which is better, Reetha (Aritha) or Shikakai?
Neither is better for every head of hair; they do the same job at different strengths. The better choice depends on how oily your roots get and how easily your lengths turn dry or tangled.
Choose Reetha if…
Your roots feel oily within a day or two, you oil your hair before washing, or you use styling product. Reetha is the more forceful cleanser, and fine hair often comes out lighter at the roots. Keep the wash on your scalp, smooth only a little through the lengths, and if your roots are still oily, do a second short wash rather than leaving the first one on longer. Reetha stings the eyes strongly, so tilt your head back as you rinse. The full method is in how to wash hair with Aritha (Reetha) powder.
Choose Shikakai if…
You want a wash for every week, or your hair is long, dry, curly, porous, coloured or tangles easily. Shikakai cleans with less of an edge and many people find their hair easier to finger-detangle afterwards. Dry or curly hair usually does best with a thinner wash, mainly on the scalp, once a week, with conditioner after. The method is in how to use Shikakai powder for hair, and switching to Shikakai covers the first few washes.
Can you mix Reetha and Shikakai?
Yes, and it's one of the most common ways to use either. Reetha brings the stronger cleanse; Shikakai makes the wash gentler.
- Mix 1 tablespoon of each for medium-length hair in a non-metallic bowl, adding comfortably warm water a little at a time until you have a thin, pourable wash.
- Let it stand 10–15 minutes, then stir again.
- Apply it to wet hair and scalp, starting at the roots.
- Massage gently for 60–90 seconds, then smooth the rest through your lengths.
- Leave it 3–5 minutes, then rinse very thoroughly, keeping it out of your eyes. Condition your lengths if they need it.
Use it up to twice a week. If your hair is dry, porous or curly, make the wash thinner and use less Reetha before you leave it on any longer. If your roots are oily, keep it on your scalp. Keep Neem out of the wash: it's a mask you use before washing.
Patch test 24–48 hours before first use, with the mix you plan to use: put a little on a small patch of clean, unbroken skin. Don't go ahead if the skin burns, swells, blisters or turns red, or if it itches and the itch doesn't settle. A patch test can't rule out a reaction later. If the wash gets in your eyes, rinse them straight away with plenty of clean water and don't rub them.
To widen the wash, add Amla, with Bhringraj as an optional fourth powder: the four-powder hair wash has the recipe.
Which should you buy first?
Start with Shikakai for a regular wash, or if your hair is dry, long, curly or coloured. Start with Reetha if your scalp is oily or you want a stronger clean now and then. Give it a few washes before you judge it, and adjust the water, the amount and where you put it before you give up on it.
Frequently Asked Questions
Are Shikakai and soapnut the same?
No. Soapnut is Reetha, from Sapindus mukorossi. Shikakai is Acacia concinna. They're used together so often that the names get mixed up, but they're different plants: the Aritha and Shikakai pages explain each.
Is Reetha the same as Aritha?
Yes. Aritha, Reetha, Ritha and soapnut all name the same fruit. The pack should name Sapindus mukorossi, whichever name is on the front.
Is soapnut better than shampoo?
Neither wins every time. Reetha gives you a one-ingredient wash you mix yourself; a bottled shampoo gives a predictable formula that copes more easily with heavy styling products. How to wash hair with Aritha (Reetha) powder covers using it instead of shampoo.
Does soapnut reduce hair fall?
No. Neither Reetha nor Shikakai acts on hair that sheds from the root. A well-rinsed wash that isn't too strong keeps hair easier to detangle, so fewer strands break from rough handling. The Aritha page explains what it does do.
Does Reetha have any side effects?
The ones people notice are dry, rough or tangled hair, fine powder left in the hair, strong eye sting and, in some people, an itchy or irritated scalp. Most come from a wash that's too strong, left on too long or not rinsed out. Patch test before first use, and stop if your scalp burns, swells, itches persistently or comes up in a rash. Reetha side effects covers each one and what to do.
Can I use them on coloured hair?
Yes. Any effective wash can fade some hair colours faster, so use a thinner wash, keep to 3–5 minutes, leave more time between washes and start with Shikakai. Neither powder is a dye or a bleach.
Do I still need conditioner?
On your lengths, usually yes. Both are washes, not conditioners, so rinse the wash out completely and use your usual conditioner where your hair needs it.
