It is a hair colour to improve the hair colour.I tried it since 1month ago.After applying it to my hair, my hair was very black.But after one week my hair us asusual.I think its validity if over.Then we have to apply it again.In one month we have to apply atleast 4times to looking like youth and young passion guys.But it is less valid.This is a drawback for us.
My best suggestion is to use henna instead of it.Henna is easily valid for 20days of time.I used henna also.I feel better with henna.I recommend henna instead if nisha color.It is useldss.It works properly for few days only, nit for more than 7days.Godreh also looking new hair.
