Re hair loss I have used these products in the past for thinning hair. The hair salon looked at my scalp with a special magnifying tool before and after use. In the before I had one hair in each follicle and in the after two to three! It's expensive but if you want to play with it when you've finished your treatments here is the link: http://www.kerastase.com.au/en-au/hair-care-new-specifique-anti-hair-loss If you are in Western Australia, Maurice Meade are into this product and very helpful. But I will wait till my chemo's done with!
