I have lots of grey hair and want to use henna/mehendi to cover them. But my friends are asking me to use colour as everyone uses colour these days. What would be a better choice?

hey Henna is a real bad option for you hair. Very difficult to remove and can make hair dry and weak from the roots. Pls take advice before going ahead with the product. use ammonia free color. That will be better. No chemical and no worry of damage :)
