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 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.

Great Scent-Dry Hair
Sampled

I liked the fact that the shampoo didn't lather, but it did make it difficult to get enough product into my hair. Afterwords, my hair felt a little more dry than usual, especially since my hair is naturally frizzy

Terrible Shampoo!
Sampled

This shampoo was absolutely terrible for my hair. I have color treated curly hair and I felt like this shampoo did more damage than good. Once I washed it out of my hair I still felt like my hair was dirty. It also left me feeling like my hair was very dry.

Interesting Product

This is the third sample I have received of this line. This particular one you can use as shampoo or as an all over body wash. Nice plus.
While it seems to work pretty well and not over dry or strip your hair, I cannot get past the chemical like smell. The scent seems to be consistent throughout their line which is too bad as it limits me reaching for the product.

No lather
Sampled

I was not a fan of this shampoo. It didn't lather enough for me to distribute through my hair. It also seemed to dry my hair out..

An Okay Product.

I like the fact that this shampoo is organic and super concentrated. A little goes a long way. I will say though, with my mother being a hair dresser, shampoos and conditioners usually cease to impress me because I'm a die-hard fan of some other professional products. This isn't a bad shampoo. If you feel strongly about using something very natural, this could be for you. I wasn't overly impressed by the clarifying but it wasn't bad!

Number 4 Clarifying Shampoo

I reviewed the Number 4 Reconstructing masque, and I had nothing but praises to lob at it. I would simply be repeating myself at this point. But, I'm going to anyways because I love this stuff. I have dry, color treated hair. So, I know my hair products. The smell is soft and subtle. Application was what you would expect from a sulfate free shampoo. You don't need bubbles, to know that a shampoo is working. My hair was soft and shiny and cleeeean! I have bangs and I stagger my hair cleaning routine with every other day just washing my bangs. I used this product for that purpose and it was amazing.

Really works
Sampled

This shampoo smells great, really cleans residue from hair and you don't have to use much but my hair is naturally dry and I only wash my hair about once every five days with limited hair product buildup so I didn't find this product worth the price for me

This is a very rich shampoo

This was a very good, rich shampoo, and I really enjoyed using the sample I received. It also has a very good scent, and the sample contained quite a few uses.

It's not just clarifying
Sampled

I used to work receptionist at salons n spas and when I hear clarifying, it means to strip off gunk and the moisture from the hair. I didn't try this for the longest time in fear that I would strip off my hair. But when I did, it made my hair clean from products and not stripped of its nutrients. I would call this Clean and replenish or Rewind, or something like that... Not clarifying. Great shampoo!

Great!

This shampoo clears the residue of about 1000 products out of my hair without making it feel dry. It smells great, and a little truly does go along way. I have lower back length with moderate thickness and I use about a quarter and just take the time to work it through my whole head.
