Awesome product line
Sampled

Birchbox sent me the leave-in conditioner, and I love that product. This shampoo is no different. I only wish there was more of it. I love the smell and the way my hair felt after using it. I'd definitely purchase this product!

I LOVE NO. 4

this shampoo is seriously amazing. i had received their protective spray in a previous birchbox and am considering purchasing it at some point even though i don't do too much heat styling. the shampoo lived up to the spray and more and was a lovely sample to receive. it smells good and lathers nicely, along with foaming up quite a bit from using not too much shampoo. it works well and seems to protect- i just wish that i had more of it!

Nice shampoo
Sampled

I have dry, over processed, chemically straightened, over blow dried/flat ironed, and colored hair. I was weary of using a clarifying shampoo, thinking it could be drying, but this was not at all! It actually left my hair feeling, well, clarified! Soft and smooth, and this shampoo has a really nice scent too! Oh, and it is sulphate free, which it a must for my hair!

Perfect for keratin treated hair!
Sampled

The shampoo is sulfate and sodium free so it was perfect for my recently keratin treated hair. Left my hair feeling clean, smooth, and soft!
