Reetha and Shikakai: The Traditional Hair Wash That Works Better Than Shampoo

Before shampoo arrived in India, hair was washed with reetha and shikakai. Not as a wellness trend — as the normal way everyone cleaned their hair, for centuries.

People are going back to it now, and mostly for one reason: regular shampoo cleans too well. Sulphates strip the scalp's natural oils along with the dirt, the scalp overproduces oil to compensate, and you end up washing more often than you need to.

What Are Reetha and Shikakai?

Reetha (soapnut, Sapindus mukorossi) is a fruit whose shell contains saponins — natural compounds that foam in water. This is the cleansing agent.

Shikakai (Acacia concinna) means "fruit for hair" in Sanskrit. It has mild saponins too, but its real value is conditioning. It is naturally low in pH, which means it closes the hair cuticle and leaves hair smooth rather than rough.

Used together, reetha cleans and shikakai conditions. That is the whole logic of the pairing, and it is why neither works as well on its own.

Why Use Them Instead of Shampoo

1. Cleans without stripping

Saponins lift dirt and excess oil but leave the scalp's protective layer intact. Most people find they can go longer between washes within a month of switching.

2. No sulphates, silicones or synthetic fragrance

Nothing to build up on the hair shaft, nothing to irritate a sensitive scalp.

3. Naturally conditioning

Shikakai's low pH smooths the cuticle. Hair is easier to detangle and less prone to frizz.

4. Helps with dandruff

Both have mild antifungal properties, and neither feeds the scalp yeast that causes flaking the way heavy conditioners sometimes do.

5. Safe for coloured and henna-treated hair

Because there are no harsh detergents, colour and henna fade far more slowly. This is a genuine advantage if you use natural dye.

6. Supports hair growth indirectly

A scalp that is not constantly stripped and rebalancing is a healthier environment for follicles.

The Traditional Ratio

The classic Ayurvedic mix is:

Ingredient	Proportion	Role
Reetha	1 part	Cleansing
Shikakai	2 parts	Conditioning
Amla	1 part (optional)	Strength and shine

More reetha means more cleaning but drier hair. More shikakai means softer hair but less cleaning power. Start at 1:2 and adjust after a few washes.

For oily scalps, move toward 1:1. For dry or curly hair, try 1:3.

Method 1: The Powder Wash (Quick)

1. Mix 2 tbsp shikakai powder, 1 tbsp reetha powder and 1 tbsp amla powder
2. Add warm water gradually until you have a thin, pourable paste
3. Let it sit 15-20 minutes
4. Wet hair thoroughly. Apply to the scalp section by section
5. Massage the scalp for 2-3 minutes. It will not foam like shampoo — that is normal
6. Work the rest through the lengths
7. Rinse very thoroughly. Powder residue is the main cause of a bad first experience

Method 2: The Decoction (Traditional, Better Results)

1. Soak 8-10 reetha and 8-10 shikakai pods in 3 cups of water overnight
2. Next morning, boil until the water reduces to about half
3. Cool, then squeeze the softened pods with your hands to release everything
4. Strain through a cloth — this step matters, strain it twice if needed
5. Pour over wet hair, massage the scalp, rinse

Keeps 4-5 days refrigerated. The liquid version rinses out far more easily than powder, which is why it is worth the extra effort.

What to Expect in the First Month

This is the part nobody warns people about, and it is why most people quit in week two.

• Washes 1-3: hair may feel slightly rough or waxy. Your scalp is still overproducing oil from years of sulphate washing
• Weeks 2-3: the transition period. Oil production starts to normalise
• Week 4 onward: hair feels clean, soft and manageable. Most people can stretch the gap between washes
• 2-3 months: visibly less hair fall, healthier scalp, better texture

If you give up in week two, you stopped exactly at the hardest point.

Common Mistakes

Not rinsing enough. The single biggest cause of rough, gritty hair. Rinse twice as long as you think you need to.

Expecting foam. Saponins produce a light, thin lather at most. Lather is a detergent effect, not a cleaning measurement.

Using it on unoiled hair from day one. Oil your hair before washing, at least for the first month. It makes the transition much gentler.

Getting it in your eyes. Reetha stings badly. Tilt your head back when rinsing.

Too much reetha. If hair feels dry, reduce the reetha and increase the shikakai.

Using coarse powder. Unsifted powder does not rinse out. Always use finely sifted.

Who Should Be Careful

• Very dry or damaged hair may need shikakai-heavy ratios and a post-wash oil
• Chemically straightened or keratin-treated hair — check with your stylist first
• Anyone with a diagnosed scalp condition should speak to a dermatologist

Choosing Good Reetha and Shikakai

• Finely sifted powder — coarse powder is the main cause of rinsing problems
• Fresh colour: shikakai should be greenish-brown, reetha light brown. Grey or very dark powder is old
• 100% pure, no added soap base or surfactant
• Sealed packaging

At Ayurveda Amrita our Pure Shikakai Powder and Natural Reetha Powder are finely sifted with nothing added. Add our Black Amla Powder for strength and shine. Oil before washing with Bhringraj Oil, and detangle afterwards with a neem wood comb.

Frequently Asked Questions

How often should I wash with reetha and shikakai?
Two to three times a week to start. Most people naturally reduce this as their scalp rebalances.

Do I still need conditioner?
Usually not. Shikakai conditions as it cleans. If your hair is very dry, apply a little oil to the ends after washing.

Will it remove hair oil properly?
Yes, though heavy oiling may need two rounds. Apply the paste to dry oiled hair first, then wet and work it in.

Is it safe for coloured hair?
Yes, and it is gentler on colour than sulphate shampoo. Excellent for henna-treated hair.

Can I mix in other powders?
Yes. Hibiscus for growth, methi for conditioning, bhringraj for hair fall. Keep the reetha-shikakai base intact.

Why is my hair sticky afterwards?
Residue. Rinse longer, and switch to the decoction method if it keeps happening.

Final Thoughts

Reetha and shikakai clean hair the way it was cleaned for centuries, without stripping the scalp into overdrive. The trade-off is a transition month and a longer rinse.

Use a 1:2 ratio, oil before washing, rinse thoroughly, and give it four weeks before deciding. Most people who get past week three do not go back.
