I really like this shampoo. It does not contain sodium lauryl sulfate which I can't have due to having perioral dermatitis. SLS is what causes soaps to lather and I'm pleasantly surprised at the great lather this shampoo produces! It smells really nice too! The conditioner is also great. I find that I use way less of this than traditional shampoos.
As for lathering, this shampoo is relatively good for a sulfate shampoo. It takes a little more effort and time to get it there, but it does lather up. Obviously not as well as a sulfate shampoo, but it does do the job without too much stress. I have found that you only need a small amount of the shampoo because it is so thick. My hair is of a normal thickness, and I only need like a nickel-sized amount of product. For the Europeans and the Brits, that would be roughly the size of a 10 euro cent coin or a penny. I have found that it helps to distribute the shampoo through the roots of your wet hair and work it in as per usual, but then duck under the shower stream again and then work the product some more. I think this really helps with the lather.
Because you only need a small amount of product means that it takes forever to use up the bottle. Coupled with the fact that you have the option to get it in bigger bottles, this means that if you intend to purchase the product regularly you don’t have to run to the store so often. This is particularly helpful because you can only find this product at a Body Shop store, not just at your local Rossman or Boots. It is also a little more expensive than something you may buy at a drugstore, but I think the long life of one bottle, plus the fact that you can get the more cost-effective bigger size makes this product not that much more expensive in the long run. Plus it is sulfate free, which is sometimes a struggle to find in cheaper shampoos!
Overall, I would really recommend this product. It smells great, does a great job despite not containing sulfate, and is a quite reasonable price for the amount of product you get and how much you have to use at one time.
