Number 4 Hair Care

Birchbox Breakdown

This sulfate-free 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. The brand's four signature Liquid Complexes—blends of natural extracts—work to protect, strengthen, and purify strands without weighing them down.

How to Use

Dispense into hands and rub together to form a lather before massaging into wet hair. Lather and rinse, then follow with Volumizing Condition.

Great Product

I really liked this shampoo. It smelled nice and gave my fine hair a lot more volume than most shampoos do.

Highly Cleansing Shampoo!

This stuff lathers for days, so a little goes a long way. It reminds me of a stripping shampoo, one that removes chemical buildup on the hair. Not sure if it would be good for every day use.

Awesome for my thin, fine dry-ish hair

This stuff is amazing. I like suds, so when I see sulfate free I get a little bummed out. Not so in this case! It still puts out enough suds. It also smells absolutely fantastic! I bought the moisturizing shampoo in the full size but definitely want to buy the volumizing too!!

Nice

This shampoo is effective and nice quality. It did the job. I didn't notice too much more volume but made my hair feel soft.

average

This product is nice, it's ready on my hair, but in already have thick hair that fluffs up on its own, so in can't judge on the volume.

An ineffective shampoo - AGAIN

I received this selfsame product in an earlier Birchbox. I am completely underwhelmed by it. It isn't in any way interesting enough or effective enough as a volumizing shampoo to merit even the slightest recommendation, and if I receive it again, I am quitting Birchbox for good.

Just Okay

This did not do much for volumizing, but it made my hair clean, so there's that. The scent is light and unoffensive.

Fresh scent

This shampoo smells really great and has a nice texture as well. I do not like the press cap, because the contents tend to leak out when on its side after traveling. And sure enough some leaked out during shipment. Since I keep my hair quite short, I don't know whether it works to improve volume. It worked well enough an average shampoo.

Great Shampoo

I'm not usually one to fall for a shampoo, but this one was so nice in so many ways. It had a nice thickness to it that made lathering up easy, the smell was great, and the overall effect on my hair was better than using my normal shampoo. This might be one to splurge on.
