Q: My hair turned whlte prematurely. Can a male dye his hair black? Can black henna be used?
A:It is not permissible to use black dye of any kind, whether henna or other. (Raddul Muhtaar V27 P89). However, red henna is allowed. Other colours that are in fashion among the west such as purple, red, brown, etc are not allowed because these are trends of the west which we Muslims are not allowed to adopt.
Don’t be grieved if your hair is grey at a young age. This is a hallmark of respect and dignity that Allah grants His servants. It comes in the Hadeeth that for every grey hair a person has in this world, so much Noor there will be for him or her in the grave and on the Day of Judgement.
