Do hair colors and Uv radiation given during facials affect the baby in the womb?

Regarding hair colouring/treatments, I've personally done my hair when I was 2 weeks away from my due date. I bleached and coloured my hair and the only uncomfortable part about the entire process was my bum hurting because I had to sit for so long. I had asked my gynae prior to this if it's safe for myself and the unborn baby and I got chuckled at! He gave me the go-ahead and so I did ;)
