DD is 11 and has curly-ish hair but has sections that aren't as curly that go really frizzy. She has a chronic illness and her hair is prone to breakage and due to her health she isn't able to have it washed regularly.
At the moment we wash it and condition it and between washes will spray with water and perhaps apply some de frizzing product or serum. Over the years we have used various products but none seem to have had much success (The most successful was probably Twisted Sista products) but dd is getting to the age where she is more concerned about her appearance and it's becoming a bit of an issue now. Any ideas ?
