Absolutely AMAZING!!!!

I got the clarifying shampoo in my birchbox box this month and it hands down the best shampoo I have ever used. It made my hair super shiny and got all of the oil out of my think hair. It is great!

Awesome hair products!

I noticed a difference the first time I used the shampoo and conditioner, my hair was shiner and softer. The sizes are great and I will be sure to buy it again when my box runs out. Super cute packaging as well if you wanted to give it as a gift.

Great Value!
Purchased

I tried the N. 4 clarifying shampoo with my December Birchbox and I was absolutely blown away by it! It is absolutely the most gentle shampoo and yet it thoroughly cleans my oily, thick hair. The low-lather formula is very thick, and a little goes a long way. The shampoo is around $30 alone, and for another $25 you get not only the full-size shampoo for large, luxury samples of their other products! Awesome.

new fave products

I received this set as a gift from my husband. It has really cute recyclable packaging, and the products made my hair feel the best its felt in a long time. I'd highly recommend this to anyone, especially if you have long color treated hair. Number 4 will definitely be a member of my hair regimen from now on.

Smells great and works well for dry hair.
Purchased

I bought this as a birthday gift for my mom (which she loved!) and have seriously been tempted to steal it for myself. The smell is heavenly and lasts long and the product texture is velvety and thick and really works to make dry hair feel soft. My usually dry ends have never been better and my mom feels the same way. Great gift and a great buy.

Love the conditioner
Purchased

This set did wonders for my damaged hair - Especially the conditioner, which instantly made my hair feel soft and healthy. The shampoo doesn't lather much, which is hard to get used to, and it was hard to tell if the protectant spray really made an impact on my thick hair, but overall I was pleased with the end result.

One use, but very happy so far
Purchased

I have only used this product once so far, but it has had great results. My hair felt somewhat brittle when it was drying, but it didn't look greasy for 3 days of non wash. All of the products smell wonderful and I especially love the detangler. I plan on incorporating this in my weekly beauty routine.
