Question

A person got irritation while applying chemical dye. What would be your suggestion for an alternative?

Short Note

Solution

If a grey-haired person is allergic to using chemical dyes then he can go for natural dyes like Henna. Henna is an organic dye obtained from leaves and young shoots of Lawsonia inermis. The principal colouring matter is Tacosone’ which is harmless and causes no irritation on the skin.
