Number 4™ Clarifying Shampoo

At the end of a long day we could all use a fresh start——and the same goes for our hair. When product buildup and styling stress leave strands feeling and looking dull, this clarifying shampoo, subtly scented with white freesia, golden amber, and warm musk, gently cleanses without stripping moisture or color. Black currant and soy restore vibrancy, acai berry and vitamin C deliver youth-boosting antioxidants, oolong tea and Irish moss defend against environmental damage, and lemongrass and oatmeal gently cleanse and purify. This shampoo is also vegan-friendly and free from sulfate/sodium chloride and parabens.

It smells nice and fresh, it cleans really nicely. it does leave my hair a bit dry, and I'm glad they sent the masque too because it really help. both products together work great.

Great product
Sampled

I was only given a small sample so it was only used one time. What I did use seemed to work effectively, smelled nice, fragrance was not strong.

This reminds me of salon quality shampoo. It's only downfall is the price. Yikes!

Helps with product buildup
Sampled

This shampoo is great for helping to get rid of product buildup. It does not leave the hair feeling too dry either

Shampoo was great
Sampled

Love the smell and the shampoo was gentle, just not hydrating enough for my dry desert hair. My husband absolutely loved it though so I passed it along to him. I have loved all the No. 4 products I have tried - they are my favorite find from my Birchbox samples.

ok shampoo
Sampled

Overall this shampoo worked great. It suds up very nicely which is very important to me in a shampoo. It also did a great job cleaning my hair. The reason I did not rank this shampoo very well is because of the smell. To me the smell of your shampoo is very important. I did not care for this smell at all. Not only did I not enjoy it while using, the smell stuck to my hair all day long and each time my hair would go in front of my face, I would smell the shampoo. I would rather my shampoo also be light enough to not smell all day long, so if I want to wear perfume, there is no smell competition.

Clarifying!

This shampoo left my hair feeling extremely clean and light, without feeling like it had been stripped of the good oils in my hair. Smells great, almost herbal! The elephant on the packaging is super cute!

Good, but not great
Sampled

I used this conjunction with the conditioning mask. It felt nice but I didn't note any significant difference from the products I normally use from other brands.

Great Shampoo

My hair is fine but full and this shampoo is great. It leaves my hair soft and fluffy but not flat.

Might be great for another hair type
Sampled

My hair is on the dry side, but I wanted to give this clarifying shampoo a chance anyway. I just used it on my roots, and it worked fine but was nothing special. I like this brand, though, and I think it might be a good product for someone with a different hair type.
