Number 4™ Clarifying Shampoo - 8.5 oz

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.

I LOVE this!

This the my favorite shampoo of all time. The smell is hard to explain, but it's amazing! I have thick wavy hair and it is left shiny, light, and clean! I am hoarding the last little bit because I'm a super broke college student.

Really helpful for damaged hair
Sampled

For me, someone who dyes their hair often, this shampoo worked some wonders on my hair. It strips the hair down, cleans out any excess, and then with the conditioner brings all of the moisture back. If your hair can't handle a strong shampoo, then this is probably not for you. It says it does not strip moisture or color, but it did strip my pink dye in my hair that was semi-permanent. I used it specifically to help fade it, and it worked!

Deep clean

Love the deep clean I got with this shampoo. My hair felt clean without being dry, which is a feat for my long thick straight hair. Love a product that keeps my roots clean without drying out the ends.

Number 4 Clarifying Shampoo is Great!
Purchased

My hairdresser advised I use a clarifying shampoo because of the chemical processing damage. I bought this after a sample was received and love this shampoo. It was a little pricy, but if you use it occasionally, like I do, it will last a long time. It really feels like it strips all the junk out of your hair. All the Number 4 products I have tried, hair spray, gel, mousse have all been great products. I highly recommend them.

A Must Try!
SampledPurchased

This product is amazing! I have had issues with allergic reactions to over the counter hair products causing dry and flaky scalp. Using the tiny sample from Birchbox (about 4 shampoos) completely cleared my dry scalp. It's clean, it's healthy , soft & shiny! The ONLY thing I would change about this product is to make it fit a better price point so I could afford to use it all the time. PS it smells great too!

Deep clean

This shampoo is great for a deep clean. My hair felt clean much longer than after using my normal shampoo. I also loved that the scent was clean without being overpowering.
