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.

Liquid VibranceTM Complex (Black Currant, Soy Yogurt, Algae, Yerba Mate), Liquid VitalityTM Complex (Acai Berry, Hibiscus, Mangosteen, Vitamin C), Liquid DefenseTM Complex (Burdock Root, Oolong Tea, Irish Moss, Vegetable Protein), Liquid PurityTM Complex (Lemongrass, Gooseberry, Organic Oatmeal, Golden Seal)

This product is very gentle on your hair. I have processed and dry hair, every time I shampoo it looks healthier!

Okay shampoo

This shampoo smells really good but leaves your hair a bit dry. Would be nice if it came with a conditioner as well

Great shampoo

This is an amazing shampoo. Gets your hair clean and also has a great smell. Great for frequent washing. Doesn't dry out your hair.

Love this shampoo!

I used this shampoo and conditioning mask for a couple days in a week. My hair was noticeably softer and more manageable. Very nice product!

Transformational
Sampled

I was a huge fan of this shampoo. I love to save these travel sizes for when I go away for a weekend and used this after a long day in the NYC heat. I hadn't brought conditioner with me and was thrilled to realize this shampoo left my hair feeling super shiny and healthy that I didn't even need conditioner. It's thicker and heavier than normal shampoo, which felt weird at first, but it certainly did the trick.

awesome

I totally love the shampoo. It smells absolutely delicious. It lathers really well and you only need a little bit. Would purchase full size even though it's a little more than I would usually spend on shampoo.

Great shampoo
Sampled

I did like this shampoo, it lathered well and rinsed clean. A big indicator to me on the quality of a shampoo is how soft and untangled it is after rinsing. Some cheaper shampoos leave my hair unmanageable until I can get conditioner in it. This left my hair feeling soft and almost as though I had already used a conditioner, yet my hair wasn't weighed down

Fantastic
Sampled

I am in love with this shampoo. I have very thick, curly, frizzy hair and I loved the way it made my hair feel after using it. Another great thing about this shampoo is that you only need to use very little amounts, so it will last you a long time. I know I got quite a few uses out of the little sample.

Great clariying shampoo
Sampled

I have used this several times this summer after going a couple of days with product build up and sweating it out at the gym and outside. A little goes a long way and it cleanses so well. I get shiny and soft hair that is smooth. I think the fragrance/scent of this product could be improved a bit.

I used this with the sample of hair masque and they seem to work well together. My hair was improving with texture after.
