How to Use Mamaearth Onion Shampoo: A Step-by-Step Guide

The Mamaearth Onion Shampoo is one of the most-reviewed hair fall shampoos in India, with lakhs of ratings across platforms. But a lot of users never follow the routine the brand itself recommends: oil before washing, alternate days rather than daily, and a cold-water finish. Those three habits cost nothing and change results noticeably.

So what's the right routine, which pack should you buy, and what can onion shampoo realistically do? This guide covers how it works, the brand's own usage method, and the mistakes to skip, plus where an onion hair oil fits and when an anti-dandruff shampoo should join the rotation.

How Does the Onion Shampoo Work?

Mechanism	Effect
Sulphur supply (onion oil)	Feeds the sulphur bonds that keep hair strong
Strand reinforcement (plant keratin)	Patches weak points while hair is wet, when it breaks most easily
Scalp moisture (soy amino acids)	Helps keep the scalp from drying out between washes

Why it suits Indian hair: most everyday hair fall in India is breakage, from hard water, heat, and rough towelling. Strengthening hair during the wash targets exactly that.

Quick Summary: Who Should Use It and How Often

Your situation	How often	Best paired with
Hair fall from breakage	Alternate days, about a two-day gap	Onion hair oil before washing
Oily scalp	Alternate days	A light conditioner on the lengths only
Dry or frizzy hair	Twice a week	Conditioner every wash
Dandruff as well	Alternate with an anti-dandruff shampoo	An antifungal shampoo on the other days

How to Use Onion Shampoo: The O-W-C-C Routine

This follows the usage guidance on Mamaearth's own product page.

Step 1 - Oil (O): Apply onion oil or your usual hair oil a few hours before washing.

Step 2 - Wash (W): Wet your hair with warm (not hot) water, lather one or two pumps on the scalp, and massage gently with your fingertips.

Step 3 - Condition (C): Rinse, then apply conditioner to the lengths.

Step 4 - Cool rinse (C): Finish with a cold-water rinse to seal the cuticle, a free step most people skip.

Best time: Alternate days, with about a two-day gap between washes, as the brand recommends.

Buying Guide: Which Pack Should You Buy?

Your situation	Right choice	Why
First bottle	The 180ml pack at Rs 199	About Rs 1.11 per ml, cheaper per ml than the 250ml at MRP
You already use it	The 250ml or larger family packs	Fewer reorders for a committed routine
You want a published clinical claim	Rosemary Anti-Hair Fall Shampoo	Its breakage results come with stated study conditions
Flakes and itching too	Lemon Anti-Dandruff Shampoo	Onion is a strengthener, not an antifungal

Side Effects and Mistakes to Avoid

The Onion Shampoo is gentle and patch-tested. Results usually suffer from a few habits:

Washing daily: the brand recommends alternate days; daily washing adds nothing.
Skipping the pre-wash oil: it's part of the routine the brand designed.
Using hot water: it weakens wet hair and dries the scalp.
Expecting it to treat dandruff: it strengthens hair; it doesn't fight the fungus behind dandruff.
Quitting before week four: breakage reduction builds over two to four weeks.

FAQs

Can I use Onion Shampoo every day?

The brand recommends alternate days, with about a two-day gap.

Does it smell like onions?

No. The gel has a pleasant fragrance.

Does onion shampoo help hair growth? It reduces breakage and supports a healthy scalp. New growth takes months, not weeks.

Which pack is best value? The 180ml at Rs 199 is the cheapest per ml at MRP.

Is it safe for coloured hair? Yes. It's free of sulfates, silicones, and parabens.

Conclusion

The Onion Shampoo works best the way Mamaearth designed it: oil first, alternate-day washes, conditioner, and a cold final rinse. Follow that routine for four weeks, and the difference shows in your comb.
