This shampoo does the job, despite the lack of suds that i normally enjoy with shampoo. I felt like i had to use the whole thing to grt a good lather. I like this shampoo a lot but I've gotten it at several hotels so I probably wouldn't pay for it.

This shampoo is a hotel amenity at a few of the hotels I have stayed in. Hotel amenities are not always the best quality. This shampoo is much better than normal hotel shampoo, but I wouldn't pay for it.

Never heard of Peter Thomas Roth prior to this box. Great shampoo helps nourish hair with enriching vitamins. Goes great with condition.

My hair is bipolar one day its oily another its dry and sometimes its normal not only does this smell so good it works everyday to keep my hair in perfect balance.

I enjoyed using it the sample is a little small i have a loty of hair and used this up pretty quick but not great either. Probably will not buy the full size at $18 -thats a lot of money for some shampoo would need to be cheaper.

Both shampoo and conditioner are great products. Makes your hair look healthy and smells great. Will definitely consider this brand over its competitors.

I have very fine, thin hair that can get weighed down with shampoos that claim to "nourish" hair. This one does not weigh down my hair at all. My hair can also get oily very quickly, when using shampoos and conditioners that are nourishing and this one does not do that either! I highly recommend this for girls with fine, thin, oily hair like mine, as it will still keep your hair nourished and healthy without weighing it down or making it extra oily.

My husband really enjoys this product. He's the type that usually would wash his hair with a bar of soap but since I've been buying the Birchboxes for men he's been more apt to trying new things. This product smells very fresh and leaves his hair very shiny and soft. It also has helped with his dry scalp. The price of the full sized product is a little spendy for 8 oz but it will last him a while.

I find this shampoo ordinary. Not bad, but not great either. Probably will not buy the full size at $18 - would need to be cheaper.

This shampoo provides a very rich lather and smells great! Rinses clean easily and doesn't dry out hair or scalp.
