Threading one's eyebrows

Q: My husband would like me to thread my eyebrows so that he finds me more attractive and makes our relationship stronger. It means a lot to him. But I am unsure if I am allowed. Although other people would see me, I would only be threading my eyebrows because he wants me to. Am I allowed or is it prohibited even if that is what he wants?

Hair dye

Q: I have heard it's permissible to use black dye, but I have a doubt. Nowadays we can't say what all the ingredients in the packets are. Is all type of dyes allowed?I have heard that our wudhu and bathing won't be correct since its a kind of paint. Often the hair colouring damages our hair. Knowing about such (scientific) damages, does Islam say "no" to use such types of dye.
