Ads on free websites

Q: I have a medical website hosted for free by a company called WordPress. Occasionally, they will place an advert on my website at their discretion. The content and image of the advertisement could be for anything, i.e: advertising insurance, a vehicle, a gambling website, a holiday cruise etc. Often an animate object is included. These adverts will often link to the respective website. I have no control over these adverts that appear occasionally nor its sometimes haraam content. - Is it necessary to change to another web-host company that does not do this, or pay a fee for the Wordpress 'No-Ads Upgrade'?

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?
