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.

This is a great clarifying shampoo. Like most of the product line, I don't think it smells very good. No bad, but not delicious. However, it's a great working product and it won't leave much scent in your hair.

I did not like this shampoo at first. It comes out VERY thick so you need to usehhalf the sample bottle just to cover your scalp. It seems you cannot put enough water on your hair to get that oily feeling out. However, my hair felt GREAT afterwards! Not oily but very soft and not dry at all!

I like trying new shampoos, but sometimes they break me out, so I love when I get a sample from Birchbox first to test it.

shampoo with little lather
Sampled

I did not think this was very concentrated, as stated, or that I needed to use less product than usual. This did not lather well or spread throughout my hair and was nothing special.

Love the shampoo
Sampled

I loved how thick this shampoo was when I used it. The smell is also very nice. The sample shampoo was large enough to use two or three times but the conditioner came in such a small package that I could only use it once. Over all, my hair smelled great and felt so clean and hydrated.
