I've decided to ditch the shampoo I've been using for years (Elvive) and switch to Lush after reading and hearing great things about their quality. I like the ethics too. I went in today but was baffled by the range. Bottles, solid shampoos and conditioners... I am stuck! My hair is highlighted with light blonde on it... also dry and fine. What would you recommend? Do the solid shampoos go all sticky after use??
