For a mini hair treatment, leave on for one minute and then rinse as usual. Use the Lumiere d’hiver Reconstructing Masque once a week to keep hair healthy.

Number 4 Hair Care

Birchbox Breakdown

This decadent conditioner helps to bring dry, overstyled hair back to life. It’'s loaded with moisturizing natural ingredients that calm frizz, restore fried ends, and protect from future damage. Vitamin B5 and jojoba help to nourish and hydrate dry strands, while Number 4’'s™ proprietary Liquid Complexes™ use potent natural ingredients like acai berry, vitamin C, and black currant to moisturize, protect, and strengthen hair. Don'’t tell our hair stylist, but this product is the reason we can go so long in between trims!

How to Use

Use on clean, damp hair. Depending on hair length and thickness, work one or two pumps through the ends and mid-length of strands. Rinse completely and style as usual.

With the shampoo, this is a surprisingly good combo. Made my processed hair soft!

Not a good smell
Sampled

This conditioner works pretty well but I can't get past the smell of it, doesn't smell fresh or pleasant to me.

Nice Conditioner
Sampled

Hydrating and nice smelling this conditioner does what it claims to. Too bad the price tag is so high - can't really justify spending that much on a hair product.

Wow

Look at the price tag. This product was good and all, but way too much for some hair conditioner! Especially since I don't have that much hair!

Works really well...
Sampled

This conditioner is actually really good. I've noticed that it reduced the tangles in my long hair during the course of the week. The downside is it smells like a salon. It smells very chemically/herby, and it lingers. Otherwise, this is a great product.

Conditioner

The conditioner is okay. However, it does make your hair oily. This would be great if you had dry and thick hair.

Nice conditioner

The shampoo was ok, but the condition was awesome. The texture, smell and ease of use. The results were out of this world.

Not bad

It made my hair soft but since I don't have much hair this wasn't of much use to me. I gave it to my girlfriend.

This is the second time I have received this product as a sample. It is a fantastic shampoo and the conditioner is equally great, but it is just far too expensive to purchase. I have frizzy hair and this leaves my hair soft and manageable every time, but it is not such a big difference from my less expensive brand to justify the purchase price.
