For ultra-healthy locks, apply Super Comb Prep & Protect after deep conditioning with Number 4 Lumiere d'hiver Reconstructing Masque.

Number 4 Hair Care

Birchbox Breakdown

After years of relying on blow dryers and irons day after day to score frizz-free locks (and, unfortunately, also seeing the resulting damage and dryness), we were skeptical of a regimen that promised shiny strands without the merest hint of heat. But then we met this kit, and we became believers: a three-step system that hydrates, protects, and leaves hair lustrous, no hot tools required.

How it Works

The sulfate- and sodium chloride-free hydrating shampoo seals in moisture and softens strands, while the jojoba-infused hydrating condition tackles frizz, dryness, and split ends. Super Comb™ Prep & Protect leave-in conditioner effortlessly detangles with nutrient-rich botanicals, at the same time protecting hair from sun damage with built-in UV filters. Finally, Fluoro5 Elixir™ Restore & Repair Oil revives, conditions, and adds plenty of gloss. 

How to Use

Apply one or two pumps of the hydrating shampoo to wet strands, massage into hair, and rinse thoroughly. Follow with Hydrating Condition. Out of the shower, squeeze excess moisture from hair and gently towel dry. Holding the Super Comb™ Prep & Protect spray bottle upright, spritz product evenly. Using a wide-toothed comb or your fingers, gently work the product through hair from root to tip. For addition shine and frizz control, work a few drops of the Fluoro5 Elixir™ Restore & Repair Oil into damp locks.

love this brand

After receiving the shampoo and conditioner as samples, I wanted to try more products from this brand. I thought this looked like a pretty good value, and it is an OK value. The leave-in conditioner and the oil are full size, but the shampoo and conditioner are tiny. It doesn't say in the description what size the products are, so I just wanted to let everyone know that the shampoo and conditioner are only 1 1/2 oz. each. That being said the leave-in conditioner and the oil are awesome. So far, I am very impressed with all the products in this brand.

Love this proudct line

This product is great becuase it all goes so well together. It doesn't leave your hair greasy. My hair is think and coarse and these products work well on my hair. The only think it didn't like is the smell, it's a little too perfumey. This back of goodies are worth the price for the size you get.

So great!

The shampoo and the reconstructing mask work so well together. Just the shampoo itself made my hair so much softer and silkier!!! With the reconstructing mask after the shampoo, the results were unbelievable! The scent is not heavenly but it's definitely bearable! Love these products!

I'm a believer!

I was really excited to get Number4 Beat the Heat in my birchbox this month; it was reviewed so highly! I really felt like it made an immediate difference in the texture of my hair. I will likely be purchasing this guy!

The products are decent but not the best
Purchased

The shampoo and conditioner are nice, but you need way more conditioner than shampoo and then you are out of conditioner before shampoo. The prep and protect spray is just o.k., but the serum is very good. It is the best of the products. It is very light weight and has a nice clean smell to it. It helps leave your hair glossy and frizz free without being greasy.

Great products
Purchased

Number 4 products do a wonderful job with my naturally curly hair, which I blow dry and flat iron frequently. I love the smell too. The only bad thing about this kit is the size of the shampoo and conditioner. They are very small. But yet you get a full size bottle of Super Comb Prep and Protect. I was expecting bigger sizes of the shampoo/conditioner.

Love using the Number 4 Super Comb Prep & Protect. It makes me feel so much better about torturing my hair on a daily base with heat. When I was purchasing it I saw this exclusive bag so I had to have it.
