From what ive heard the sun reflecting off of the snow (if their is any by chance) does some good damage so id say you should wear some in the winter, but i personally dont cause my heads whiter then the rest of my body lol
I put sunscreen on my face when I go skiing, but other than that I usually am indoors or am wearing a cap.
I`m the same way.I wear a scully cap when I`m out doors in the winter.Headblade sells a nice one on their site.
I use it everyday of the year.
I live in Scotland. The sun comes out in summer which lasts for about 2 days in July. 
That's a little depressing isn't it.
Yes m8. Try living in it. I had a friend who emigrated from Scotland to Canada because she wanted to see the sky. Too much cloud here.
Hope she didn't move to British Columbia
I was about to say the same thing! My friend from Vancouver always said it's never sunny there.
I don't use sunscreen in the "winter" No snow down here
