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.

Smells funny.

I love hair conditioners so this was good to get in a birch box but it doesn't smell good so it's not my favorite.

Love the smell of this set
Purchased

I was forewarned from another reviewer that the shampoo and conditioner come in a very small sample type size. I think that should absolutely be added to the description so people aren't put-off when they receive the product. The shampoo & conditioner has a twist off cap which is a pain to deal with in the shower - the smell is fantastic so I will continue to use. The leave in conditioner works really well, I have very thick, coarse hair and am able to easily brush through after spraying - and it smells great! The oil does add shine and seems to keep away some of the frizz. I'm excited to have these products when the hot weather comes. Overall, a good purchase - I may buy the spray conditioner again but it is very expensive on its own, it makes sense to buy the set.

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.
