I love this shampoo. I bought it after I received a sample in my box. It has a great scent and leaves my hair feeling clean without any residue. I recommend this shampoo to everyone.

Bought the Full Size Immediately!

This stuff smells great, but not overwhelming to me. Scent is a personal thing though so just know that it does have a scent. More importantly, it did a great job of cleansing my thick , shoulder length, wavy hair. I swim a few times a week and my hair goes from dry to oily in just a few days, but this seems to help keep that under control. It's not as frizzy now and has a nice shine to it. The sample I received was adequate in size and I'm reusing the bottle for travel. One hint - if you're buying this with the conditioner (also recommended!) look at the shampoo/conditioner set. This shampoo was out of stock when I first tried to order it, but the set was still available.

Amazing

This is the best shampoo I have ever used. It hydrated my hair so well, and the smell was absolutely amazing. It is a little pricy for shampoo and normally I am not the kind of person to pay this much for it. This however is my one exception it is well worth the money being spent!

I absolutely love this shampoo. It leaves my hair soft and hydrated and I don't even need to use conditioner with it. It also has an incredible smell that lasts through the day.

I received this sample in a my Birchbox recently. I have fine long colored hair and it tend to be oily, so I wasn't sure if this shampoo would be effective. I was pleasantly surprised that the shampoo effectively removed the product build up without overdrying my hair. I love that its gentle enough to use often. I'd consider purchasing in the future.
