Hello, Thanks to Practo for easy consultanting approach. I am 27year old, previously during college time I use to apply artificial color. Last couple of years I started using Kajal Mehndi product for dying my hair even I applied for beard. Suddenly, after some months my hairs had turned gray around 60% of my hair on head are gray.n same goes with my beards. I would be so thankful if you can provide me solution for this. Your early reply will be highly appreciated. Thanks Regards Have a great time.
