Birchbox Breakdown

Whether your hair is over-processed and brittle or just chronically dry, this is the shampoo for you. The satiny formula is gentle enough to use every day and helps to soften and hydrate strands with natural essential oils and extracts. Free of parabens and sulfates, it foams into a rich lather that leaves hair soft and shiny. Vitamin B5 conditions hair and silicone bumps up the gloss factor, while the brand’'s patented Liquid Complexes help protect, purify, strengthen, and revitalize hair.

How to Use

The concentrated formula goes a long way. Depending on hair length and thickness, apply one or two pumps of shampoo to your and work into a lather. Work into wet strands and rinse thoroughly and follow with Number 4 Hydrating Condition.

Giving it a try.

I liked the fact that it lathered up really well, but the smell bothered me. Still, it did seem to moisturize my hair so I might try it again.

Nice feel, bad scent
Sampled

I like the way it makes my hair feel during washing and after rinsing, but I'm not thrilled about the scent...it has a bit of a "rich old man" flair.

Certainly does the trick!
Sampled

I really liked this shampoo! My only complaint is the scent was quite masculine and musky. Some people are into that, I'm just not that into the masculine scents!

Nice Shampoo
Sampled

There's nothing special about it, but it's not a bad shampoo. Might be worth buying if I didn't already have a shampoo that is great. Maybe after this shampoo is done I can try this one. The fact that it's free of sulfates is great for curly hair.

great for dry hair
Sampled

Its too moisturizing for me. I have normal hair. I think it's great for color treated or damaged hair. I will try another formula of this brand in the future.

AMAZING
Sampled

I don't usually spend a lot of money on shampoo and conditioner just because my hair isn't very finicky, my hair is fine and straight. After using this, I was in LOVE, you don't need a lot of product, it leaves your hair feeling clean and healthy and it smells so fresh. Would definitely recommend to any hair type.

eh

The smell was almost too cologne-y...not sure I noticed any difference in my hair either? I didn't notice it's softening quality - but I'm going to give it another shot!
