After my exciting discovery of Next skinny jeans a fortnight ago, I've since found some brilliant shampoo in Primark of all places.
My local store has had a revamp and is now stocking Hask keratin shampoo and conditioner. I've not heard of the brand before but I have longish curly hair, which tbh can be a nightmare to control. I've seen loads of threads on here about keratin treatments so thought I'd give it a go and it's bloody brilliant!
My hair is amazingly frizz-free and the curls are really defined. I can't get over how different it looks. The shampoo is sulfate and paraben-free, which may also help.
I think it was £4 per bottle so not expensive either. Be interested if anyone has heard of Hask at all.
