Anyone with experience in arm waxing?

Question

Will the hair grow back thicker and darker, or will it thin out?

Answer 1

With waxing, the hair is pulled out at the root. Generally, the hair should not grow back thicker and darker but much thinner. The hair will eventually grow back quite thin after a few times waxing. That is my experience.

Answer 2

It will look the same.  After a while you'll notice that the hairs seem finer and lighter and take longer to grow in.
