This singular shampoo proves that style and substance aren't mutually exclusive. The sleek packaging and fresh scent are a nod to Parisian flair, while the scientific formula is designed to turn fine, flat strands into rich, full-bodied hair. (No strings attached.)
I LOOOVE this shampoo!!! My hair wasn't frizzy. I want the full product.5
Best product ever! Makes my face so clean and clear! Never using another product again! Such a great little find! Thanks birch box!
This product is great. I love the smell... it lasts all day. I have very thin hair and it can get weight down by heavy shampoo and this is meant to give volume and it does! I usually have to wash my hair every day because most shampoos make my hair oily, I can go two days with Number 4. I wish it was less but it's such high quality.5
I have very fine hair. I sampled this and had to buy it. My hair looks thicker, keeps the style all day and best of all smells good. I will buy this again.4
I love this and several other No. 4 products. I purchased the Super Comb Prep & Protect, Volumizing Shampoo and Volumizing Conditioner soon after trying in my Birchbox. They are my favorite products which I use everyday. I will continue buying and would recommend to anyone!5
I really liked this product. I felt like my hair had lots more volume after using it. It also felt very smooth and soft.5
It was ok ! Don't think I would go out a buy. Glad I got to try it out first!3
i really love this brand. this product works very well on mixed hair, oily and dry. the smell is very soft. the presentation is very elegant.5
I did not find this product very good at cleaning nourishing and replenishing.1
I honestly love this product. I bought the full sized version of the shampoo and conditioner and use it regularly. It smells great and does a great job adding volume to my hair, and it has been the only shampoo/conditioner that I can see noticeable results from it's use. My only question is whether it is worth the price tag. Sure it does a great and noticeable job, but could I buy a less expensive alternative and substitute the volumizing effects by the use of additional hair product?4
