My daughter is just five.She has never had a haircut,and her hair is collar length at the longest.It is fine,curlyish and fluffy,and seems really slow growing.She has started to get upset about it as she wants long hair like her best friend.My smaller daughter( 2 3/4)has longer hair.I am a bit concerned in case she could be lacking something in her diet as all her friends have long hair or hair that is repeatedly cut.I feel a bit silly asking my GP about it,so thought I'd ask you lot instead!
