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 to score frizz-free locks (and also seeing the resulting damage and dryness), we were skeptical of a regimen that promised shiny strands without a hint of heat. But then we met this kit, and we became believers: It hydrates, protects, and leaves hair lustrous, no hot tools required. The sulfate- and sodium chloride-free Hydrating Shampoo seals in moisture and softens strands, while the Hydrating Condition tackles frizz, dryness, and split ends. Super Comb™ Prep & Protect leave-in conditioner effortlessly detangles with nutrient-rich botanicals and protects 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

Cleanse and condition hair with the Hydrating Shampoo and Hydrating Condition. Out of the shower, squeeze excess moisture from hair and towel dry. Spritz the Super Comb™ Prep & Protect evenly, and use a wide-toothed comb or your fingers to distribute the product through hair from root to tip. For additional shine and frizz control, work a few drops of the <a href=/shop/number-4-lumiere-d-hiver-fluoro5-elixer-restore-repair-oil">Fluoro5 Elixir™ Restore & Repair Oil into damp hair.

love this brand
Purchased

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.

Great way to try it.
Purchased

I stand by this brand. ALL of their products smell great, feel light, and get the job done. Number 4 is like a liquid spa for your hair. Natural ingredients, fragrant without being overbearing and you feel the difference after one use. I bought this for the travel sizes - so I could pamper my hair on the road. I'd buy this again - becuase it's a great value.

Great brand!
Purchased

I am loving the number four haircare line. I received a sample of the Prep and Protect, and it was great. I liked the fresh smell, and it made a difference with my hair, which is thick and tangly. I ordered this kit afterwards, and the shampoo and conditioner are awesome. Very nourishing, and I plan to purchase the larger sizes. This is a great kit, great value.

Love the full size leave in conditioner
Purchased

Overall I really liked this. I don't think I'll order it again though. I didn't like the shampoos enough to continue to order them - I think they are far too much money to spend on shampoo. Great quality! They did make my hair feel really soft and clean. I will forever love the leave in spray conditioner. That I will continue to order. It smells amazing and really helps detangle long hair. The shine is nice, it does do a great job of taming flyaways, but I don't think it is really all that special - pretty standard as far as that kind of product goes.

Love the detangler spray
Purchased

I received a sample in my birchbox. I fell in love with the product and wanted the full size product. This value pack gives you the most bang for your buck. The scent of the spray and oil are awesome. I could wear the spray as perfume. The only downfall is the small size of the shampoo and conditioner.

AMAZING
Purchased

I bought this set after being impressed with the samples from this brand that I had received. Boy, and I glad I got this. The hydrating shampoo is amazing, as is the elixir. I have tried many hair care products and am perfectly willing to spend money for good quality. And this is it, my friends! Used the full set the other day and my hair is soft and I couldn't be happier.

Great lineup!
Purchased

I love these products. The shampoo and conditioner leave the hair soft and shiny. The spray does a great job detangling, and the oil repairs damage like nobody's business. One word of caution: a little oil goes a long way. My hair is past my shoulders and I only use two pumps of it.

Meh
Purchased

The Super Comb Prep & Protect spray is, and always will be, my favorite BB product. If they could bottle that smell as a perfume, I'd be all set. They were sold out of it individually, so I thought I'd try some other products of Number 4. Frankly, I'm not overly enthused. The shampoo and conditioner have a very heady smell (exactly like Moroccanoil, if you are familiar) and really made my hair look dull, not hydrated. Surprisingly, the elixir oil isn't really doing anything for gloss either. I have fine hair, but lots of it, so I don't know if it work better on a different hair type.
