When I melted my hair with home colouring I was advised to try elasticiser and it did help my hair to recover sufficiently so that I didn't have to have it all cut off. But it only works if I sleep in it and since I've been using Wen for about 6 years my hair is the in the best condition and I still abuse it every 3 weeks with dye. I'm dithering over the BPOTM because the rhubarb scent is lovely (a small tube was in this year's BB goody bag, thanks to Jenny my QVC-aholic neighbour!). But a litre would last me 3 years, possibly longer...and Mr Akimbo has developed an aversion to litre bottles in the bathroom, what with Purity, Wen, Tea Tree Wash etc!
