I've used this shampoo for little over a week now - Firstly, I love the fact this shampoo is Sulphate & Sodium Chloride Free, Gluten and Paraben Free!
Considering it is sulphate free, it lathers up really well and a little goes a long way (you need to emulsify in hands first). It has a subtle fragrance which borders on masculine but I actually like that.
I've used many high end shampoo's and I have to say I am really impressed with this one (I have long, thick, sometimes unruly/frizzy hair), it left my hair soft, shiny, weightless and healthy looking and appears to definitely be colour safe. I usually struggle with hydrating shampoos being a bit too heavy for my hair, leaving it lank, but this wasn't at all. I haven't bought the conditioner yet (will be purchasing this next) however I followed it No.4 Super Comb Prep and Protect (I purchased at same time as shampoo, which detangles and heat protects) ....all in all a really lovely shampoo, my only gripe its expensive for 250ml (I used points and hence 4 stars) but as I said, I love the fact it contains safe ingredients and if it carries on performing its totally worth it!
