The LUSH Rehab shampoo was definitely a splurge for me, but totally worth it. It looked weird when I first got it the product looked like a type of italian dressing, and you have to shake it up until it emulsifies together. The scent is very mixed it's hard to pick up exactly what it smells like, but to me it's like a herbal mint with some fruit. This shampoo is very runny I have to be careful not to pour out a lot I only need a small amount for my long hair. It works up into a crazy lather, but washed out of my hair just fine with ease. The results I got from using this shampoo are fantastic. My hair felt cleansed throughly making a good amount of body to my long hair that usually doesn't have enough volume on its own. My hair didn't feel dry or brittle like with most shampoos I used I can tell that this shampoo has made a difference to the way my hair looks. It can work on all hair types, and be very beneficial with all the great ingredients it is made out of.
