Number 4 Hair Care

Birchbox Breakdown

Much like a dull conversation, dull hair should be avoided at all costs. This everyday shampoo (which does double duty as a body wash) deep cleanses and repairs damage while locking in much-needed moisture. The sleek pump dispenser adds instant style to your shower while ensuring you get as much or as little product as you need.

How it Works

Rich in vitamins and antioxidants, this clarifying shampoo restores health to all hair types. Black currant and soy add shine; acai berry and vitamin C deliver age-fighting antioxidants; Oolong tea and Irish moss defend against environmental damage; and lemongrass and oatmeal cleanse and purify.

How to Use

Apply one to two pumps of shampoo to wet hair and scalp. Lather, rinse, and repeat as needed. May also be used as an all-over body wash.

Liquid VibranceTM Complex (Black Currant, Soy Yogurt, Algae, Yerba Mate), Liquid VitalityTM Complex (Acai Berry, Hibiscus, Mangosteen, Vitamin C), Liquid DefenseTM Complex (Burdock Root, Oolong Tea, Irish Moss, Vegetable Protein), Liquid PurityTM Complex (Lemongrass, Gooseberry, Organic Oatmeal, Golden Seal)

Good stuff!

I received both this and the reconstruct masque in my box. My hair hasnt looked, smelled, or felt this great since mt teens!! I literally logged in just to buy it... then I saw the price. It really is great stuff! But I cant justify paying that much for hair care.

It's alright.

I have color treated hair, so I'm wary of using clarifying shampoos because I fear it'll strip my color. However, this stuff really didn't seem to lather or clean my hair very well at all. I also found the texture to be way too sticky for me.

Smells like Grandma
Sampled

I followed the directions carefully and used the recommended amount but I feel like I couldn't get it all out of my hair. The next day it made my hair look really greasy even though it was just washed the night before. Also, the smell is not for me. It reminds me of a Grandmother smell.

Effective clarifying shampoo but drying
Sampled

This is a very clarifying shampoo - however it is quite drying. It smells lovely but I would only recommend it if you have very oily hair.
