Assalamu alaykum w.w. Could you tell me if we can use haircolour and which we can use. Jazakallah
Assalamu alaikum Warahmatullahi Wabarakatuh
Haircolour is permissible barring jet black hair colour. Of course they must not not contain animal derivatives. After the colorant dries, it must not produce a waterproof film on the hair so the colorant does not affect Wudhu or Ghusl.
