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.

Wonderful Shampoo!

My fiance received this in her BB, and when I nabbed it I was pleasantly surprised. With just a small amount, your hair will feel as if you shampooed AND conditioned! Has a very pleasant smell too. We will be purchasing.

Smells great! Love it.

This shampoo smells great! My hair felt soft and super clean. It removed all the heavy weight built up from products. It cleaned my hair so well I am a little afraid to use it with the new lilac purple elumen color that is now in my hair. I think it might fade the color faster. But if your looking for a great product clearing shampoo that smells great and won't leave your hair feeling dry, this product is it! I have thick curly hair but straightens easily with an iron or blow out. Hope you found the review useful.

I have been struggling with dry scalp for months, and have tried so many different brands. This formula leaves my scalp feeling good, not tight, and there are no flakes to speak of! And the smell is amazing! This shampoo leaves my super thick hair feeling clean, light, and balanced.

Not my favorite
Sampled

I didn't care for this at all. Dried out my hair something terrible and it smelled gross. I love the smell of freesia but this did not smell like freesia at all. I wanted to like it so I used it twice. Not impressed either time.

Meh

Nothing special. I gave this one to my boyfriend because he was out of shampoo. My hair is too dry and damaged to use something like this. I'd Birchbox were more personalized, maybe I would get things that would work better for me.

So far this is my favorite sample of shampoo yet! The smell alone is intoxicating and the shine and softness it gives my very colored and damaged hair is hard to find! Love love love!

The Number 4 Clarifying Shampoo is by far the best clarifying shampoo I have found. I use it before keratin treatments because it does not strip the color from my hair.

Good shampoo
Sampled

This shampoo had mild smell and was even good to use. However, I was very upset with the size of the shampoo. I could use it only twice considering that I only have medium length hair. Please consider quantity an option!
