Not a good shampoo
Sampled

I have tried this brand but it doesn't work for me. I don't like the smell and it left my hair feeling dry. I wouldn't recommend this product to people with frizzy hair.

Number 4 hydrating shampoo
Sampled

I have super long hair so i was only able to use the sample once and it was almost not even enough. Shampoo doesn't smell good at all... and my hair didn't feel any different afterwards. Will not purchase full size

Not What I Would EVER Choose
Sampled

I was excited to try this brand, especially the hydrating line, so I was okay seeing a shampoo sample in my Birchbox this month. Then I used it with the very small foil packet of conditioner from the same line. Wow.....If I wouldn't have kept a hair masque in the shower that I had gotten from Birchbox previously (that lasted forever, fyi) my hair would have been a disaster! This shampoo AND tiny conditioner did NOT hydrate to say the least! HUGE MISS for me Birchbox.

Just not for me

The smell of the product was aweful. The actual product was not effective on my hair type and flattened it out.

Number 4 Hydrating Shampoo
Sampled

I had to throw this shampoo away after the first use. The smell was so overpowering it gave me a head ache that lasted all day. It smells like it's a man's shampoo.

Horrible scent
Sampled

The shampoo had the worst smell. It reminded me of my grandmother's old lady perfume. It was extremely overpowering. Worst part is that there is no noticible hydrating effect on my hair even when used in combination with the conditioner. Overall complete fail for me.
