After a good towel dry, get a long-lasting hold and finish with Number 4’s Firm Hold Gel.

Number 4 Hair Care

Birchbox Breakdown

Much like a dull conversation, dull hair should be avoided at all costs. This everyday shampoo (which does double duty as a body wash) deep cleanses and repairs damage while locking in much-needed moisture. The sleek pump dispenser adds instant style to your shower while ensuring you get as much or as little product as you need.

How it Works

Rich in vitamins and antioxidants, this clarifying shampoo restores health to all hair types. Black currant and soy add shine; acai berry and vitamin C deliver age-fighting antioxidants; Oolong tea and Irish moss defend against environmental damage; and lemongrass and oatmeal cleanse and purify.

How to Use

Apply one to two pumps of shampoo to wet hair and scalp. Lather, rinse, and repeat as needed. May also be used as an all-over body wash.

I love this so far! My roots tend to get greasy easily so I am always wary about using oils on my hair. This works perfectly on my ends because it does not have that heavy oily feel. Its lightweight and has a very light clean scent.

What a Masque!

With straightening my hair all the time I needed something to give back my shine & protiens. After doing this treatment my hair felt healthy and shiny. I loved this sample!

I love it

I have to tell a funny story, I got this in my Birchbox and I can't see well and couldn't make out the writing on the small pack. I thought it said it was a MASK so I put it all over my face and then rinsed. My face feels wonderful!! I can't wait to try it on my hair! The next time I will put my glasses on!

Weightless Shine

Love it! I have very very fine, long, color treated hair, so I need a little extra strength/moisture and shine without weighing down my hair any more than usual. I've tried all sorts of serums and glossing creams and stuff in the past with usually average results at best - either I'm not getting the shine results I want or I look like a wet dog, all weighed down with goop. Bought a bottle of this on a whim since I've been such a fan of the other Number 4 products I've sampled, and I'm SO glad I did. This is it.

After a couple of uses, hair is exceptionally shiny and looks healthier than usual. However, my hair is NOT weighed down at all. If anything, it's moving more than usual. And it feels super soft. I'm hoping continued use does improve the health of my hair, but even if not I'd keep using this stuff based on looks alone.
