This is a super expensive hair care line, but once you start using it, it's hard to go back to anything else. The volumizing shampoo smells great but can be a little drying. It does pair well with the moisturizing condition, so that can cut down on the dryness.

This shampoo was noticeably different after one use. It is pricey, but I would use it for special occasions. My hair was actually full and bouncy and mine usually falls on the thin side, but a lot of it. Highly recommend.

Oh my where do I begin.. This shampoo is hands down UhMayZing! I spent $34 on each shampoo and conditioner from Birchbox & I will continue buying. Its so worth the price. The quality is beyond incredible and the results exceed any expectation I've ever had for a shampoo. The hydrating version doesn't smell as good to me, but it works wonders. It makes your hair soft and tames Flyaway's. I even got my fiance using it (Shh). Highly recommend. You pay for what you get & you will be more then happy with this product. 10/10

The best shampoo I've tried yet! I first received this as a sample but quickly fell in love and although it's a bit expensive well worth the price. I have thick curly color treated hair and this shampoo doesn't strip my hair. It smells lovely but not too overbearing. My hair isn't frizzy afterwards. Just a clean, silky feel. Paired with the conditioner and you are set! Would highly recommend!

The smell is amazing. I can’t speak to it adding volumetric not, however I have not experienced any product build up. My hair and scalp feel soft and clean. I have tried other products and always return to this.

This is my favorite shampoo! It has a wonderful light floral fragrance. If you use a small dot of shampoo and rub your hands together to get it to lather the bottle will last you months

I absolutely love this shampoo. It smells great and has been good to my hair. I have color treated hair and this shampoo really takes care of it. I also have problems with having oily hair and this shampoo literally keeps my hair clean for 3 days at a time. It is great and worth the money you pay. My hair is in great condition and I get hair cuts less because my ends are looking great. I do have a ton more volume using this shampoo as well.!

Good product. Smells great. It can be expensive, but worth the cost. Doesn't weigh hair down.
