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.

Lovely texture

I really like how his shampoo feels on my over processed colored hair. It lathers up well and feels very nourishing. I'm sure it's good at getting all that leftover product out.

Great Product
Sampled

So far I have been happy with all of No. 4 hair care products. My hair feels very soft after one use with this product. It smells similar to other no. 4 hair care products and I don't really like the initial scent.

Not impressed
Sampled

This shampoo was nice to use but I didn't see any difference from other clarifying and cheaper shampoo products. If you want to treat yourself , it's a nice product but in my opinion not worth the price.

This is a great everyday shampoo. Not sure I'd pay $32 for it, but it did work great.

Smells incredible!
Sampled

This shampoo works great on my hair but it says to use a small amount since it is concentrated...however I ended up using the same amount as I do with my other shampoos as it doesn't seem to have a lot of foaming/suds action unless you use a little more. This wouldn't keep me from purchasing this in the future if I still like it after multiple uses. It smells so good. Its not the same smell I typically find in shampoos and when I straightened my hair afterward, I could really smell it again!

Not enough moisture
Sampled

I used this along with the #4 conditioner. I have dry, fine, colored hair. I don't use a lot of product, so I didn't really need a clarifying shampoo. It does smell great and when I was lathering it didn't feel to drying. But after I used it with the provided conditioner my hair was really stripped. So I wouldn't buy this.

Smells Great and Like that You can use on your body
Sampled

I am more likely to use it as a body soap than in my hair. Didn't feel like it did the job in clarifying my hair. I have another product I like more. Smells great though.

Not for me, but loved it
Sampled

Although I almost exclusively use Kiehl's shampoos, I did enjoy the way my hair smelled after using this product. I probably won't end up buying this product, but I do recommend it as a shampoo option.

Sublimely Citrus

I really enjoyed this shampoo. While in the shower you are left with a nice citrus smell. Didn't notice anything amazing afterwards once my hair had dryed.
