The shampoo and conditioner are sold as a set for £24.99 in Boots and the bottles are 300ml each. They lasted me for nearly four weeks, and I wash my hair just about every day.
Using the Fast shampoo and conditioner felt just like using any normal products. The shampoo lathered easily and the conditioner was fairly creamy and moisturising. I wondered if they'd have a funny consistency, or a chemical smell, but they didn't at all and actually they're made with a blend of natural herbs, vitamins and amino acids, with no sulphates or parabens.
After using these products for a couple of weeks I started to notice that I might need a trim for my split ends, and that's when I first thought that my hair might have been growing faster than normal. By the end of the bottles I really do feel like my hair has grown, although it's hard to tell for sure because I don't usually watch my hair growth so closely or measure it! I'd certainly buy these and keep using them to try to get hair of Khardasian proportions!
