DS has very thick and slightly wavy hair - just like me! He has it long. Well, long fringe and longish elsewhere, and the hairdresser thins it out, just like she does mine. We both get lots of comments about how nice our hair looks
MMine is a good shoulder length and I can still tie it up. I have had it thinned alot over the years, from being a child and it hasn't done me any harm! I have like a triple or quardruple thickness ponytail compared to my DD who has never had her hair thinned, but I think inherited her Grandma's / Nanny's hair!
