I could really do with some tips on how to encourage washing hair with shampoo.....my nearly 13 year old is struggling with personal hygiene and didn't like the way her hair looked (too fluffy) after hair washing last time. Now refuses to use shampoo and her hair is so greasy and desperately needs washing. Very anxious / sensory profile. Tried backing off, tried buying organic shampoos, tried getting someone else to wash. The hair needs to be washed ! Any ideas ?
