Lillah and charity

Giving sadaqah

Q: I know I am supposed to listen and obey my parents but I wanted to give sadaqa on a regular basis where the charity takes the money out of my bank account weekly but my dad said not to do that saying we don't have much money and just to put some loose change in sadaqa from my pocket now and then. However, I do feel that I have sufficent funds for my needs and the rest is spare. So what shall I do, shall I listen to my dad or shall I just keep giving on a regular basis from my bank account?

Donating one's hair to make wigs for children with cancer

Q: I am a female in need of advice about the cutting of hair in terms of disposal. I cut my hair on Friday and someone mentioned this foundation to me where you can donate your hair and they make wigs for children with cancer to use. Now my mum says she's not sure if it's a good idea because Islamically you must bury your hair and I agree with that. However, I really just want to make a difference for a cancer-suffering child and of course I won't do it if it's wrong. My question is: Is it wrong to donate your hair for cancer patients?
