DR.JAIN's Dr. Jainâ S Bypurenaturals Dark Shade Herbal Hair Colour Treatment Powder, 100G (Set Of 4) - Black

It works. But I think its not harmful for long time use. But I have no such Idea or confirmation aur research.

I have been using it for last five years. Perfect product to hide grey hair with Greynil.

It has to be used multiple times to get the desired shade, so be patient. After 4-5 applications one gets a burgundy shade, not the orange red of pure henna and I like the shade. If one uses this as a dye one should ideally use it every 8 days or so. You cannot expect it to colour your hair like a chemical dye does. This product is available a reasonable price so I bought it. Yes, it's a lot of work, colouring the hair every week almost, but my hair is becoming thicker, softer. So even if this is not as effective as a chemical dye, it doesn't matter. It depends what you prefer. A chemical dye which harms your hair but gives a super effect, or a mehendi based dye which is natural, takes more time and hard work to apply, but protects the hair.

Product is good, just the rate with freebie oil that you are providing is not required as by that you are increasing overall rate of product, plus already added delivery charge make it more costlier

Good to use

Excellent alternative to harmful chemical colours. Nedd to be applied more often than chemical color though.

Received a very nice and instact packaging. The product was good, easy to use with full instructions and details inside. Also, the delivery was prompt.

The quality of this product has deteriorated way too much. It barely gives any color any more.
