Hello, looking for some help with my Dd's hair which is currently a disaster. She is 11 years old so I think the hair problem is hormonal. It has been getting greasier over time and this morning she has set off for her first day back at school in tears as it looks so bad. She washed it last night but has woken up with a greasy mess. Does anyone have advice on which products to use, how often to wash etc. Really want to help her as she has poor self esteem when it comes to her appearance already and having bad hair is not helping. Thanks
