I'm glad this question has been asked!

I just bought a couple of packets (semi perm) today. I have done my own hair only twice before and it worked out great. It was a while ago and I think I only stopped because I went back to blonde streaks, so went to the hairdresser for that.

Since seeing old photos of me with blonde hair, I have decided dark is best for me now and will probably continue doing my own from here and just go for a haircut when needed.

Thanks for all the tips everyone has supplied
