We got rid of our Tigi after hearing this too, there are way too many salons in our area who were using this and wanted to be different.
We tryed Sexy Hair on sale or return, most of the products were good, but the range is just too big. Stocking them on your shelf is like walking into Boots, they all look so different it's confusing.
We ave now switched to Osis and opened an account with Schwarzkopf, its affordable for clients, the Bonacure shampoo is lovely.
I would totally reccommend Schwarzkopf x
