How does it ruin your hair?

For ages, people have trusted natural mehendi over chemical hair dyes. But experts now reveal a shocking truth: while it's natural, using mehendi too often can slowly damage your hair. Let's find out how this happens.

It absorbs natural moisture and oil

Henna contains a chemical called 'tannin', which gives that rich reddish-brown colour. But tannin also sucks up your hair's natural moisture and oils. Repeated use makes hair dry and brittle, causing it to break easily when you comb or wash it.

Permanent changes in hair texture

Many people love how thick their hair feels after applying mehendi. But here's the problem: henna doesn't penetrate the hair; it just forms a thick layer on top. Over time, this coating makes your hair lose its natural softness, especially if you have silky hair.

Weakened roots and hair thinning

We think mehendi is a great conditioner, but too much of it does the opposite. The henna layers build up on your scalp, blocking oxygen and nutrients from reaching the roots. This dries out the scalp, weakens the hair follicles, and leads to thinning and severe hair fall.

Allergies and severe skin problems

Never assume 'natural' means 'no side effects'. Some people are allergic to the proteins in mehendi. This can cause redness, severe itching, and rashes on the scalp, sometimes leading to a condition called 'contact dermatitis'. Always do a patch test first!

Problems when using chemical colours

One of the biggest side effects is that you can't use other hair colours after mehendi. The henna coating prevents chemical dyes from penetrating the hair shaft. The result? The colour won't take properly, and might even react with the henna to turn your hair a weird green or orange.

What is the expert's advice?

You don't have to stop using mehendi completely, just change how you use it. Apply it only once a month or two. Mix it with curd, egg whites, or coconut oil to prevent dryness. And always use pure henna powder, not 'instant' or 'black' mehendi which contains a harmful chemical called PPD. Remember, moderation is key.
