Hair and Nails

Burying hair

Q: Please tell me what Ii should do with my fallen hair which I have collected since 10 years. I am not throwing it out because I don't know where to throw it? If I throw it in the sea, won't it cause harm to the fish? Shall I bury it in a Muslim graveyard?

Dying the hair black

Q: I am a twenty years old. Since January I have a disease. Now I am recovering. My question is that this disease has caused my hair to turn white before age. I know that it is haraam to pluck white hair and also that one falls in Allah's eyes by doing such deeds. But I have also heard that young muslims can even dye their hair black if they wish. I want to ask that is it permissible to pluck such white hair that are growing before age and are a result of a temporary disease?

Waxing

Q: Are all these ways (hot wax, cold wax, razer machines, creams) to remove body hairs (legs, hands, face, underarms) permissible for a woman as there is a great misconception among people. Please do elaborate it in detail.
