Hi all looking for some advice.. I've always had fine hair and over the last couple of years its become pretty thin too, with my scalp becoming quite visable around the crown. I had been considering hair extensions but was worried about making my hair worse that I have instead concentrated on hair health e.g regular trims, no heat, no dye, weekly hair masks etc however i miss wearing my hair down and it not looking so thin/boring and unstyled! So anyway hairdresser has suggested 20-25 nanos for volume only but I can't decide to go for it or not! Anyone had nanos for volume in thin hair and would recommend?!
