Number 4™ Lumiere d’hiver Fluoro5 Elixer Restore & Repair Oil Customer Reviews

Use very sparingly and in small amounts or else your hair will look very greasy

Love it! I have very very fine, long, color treated hair, so I need a little extra strength/moisture and shine without weighing down my hair any more than usual. I've tried all sorts of serums and glossing creams and stuff in the past with usually average results at best - either I'm not getting the shine results I want or I look like a wet dog, all weighed down with goop. Bought a bottle of this on a whim since I've been such a fan of the other Number 4 products I've sampled, and I'm SO glad I did. This is it.

After a couple of uses, hair is exceptionally shiny and looks healthier than usual. However, my hair is NOT weighed down at all. If anything, it's moving more than usual. And it feels super soft. I'm hoping continued use does improve the health of my hair, but even if not I'd keep using this stuff based on looks alone.

I use just a few drops on the ends of my wet hair and I enjoy the texture and shine that the producr provides. I have really dark, thick, long hair, so most products that I have tried I need to use tons to get the desired effect. This stuff really works with minimal application. Smells great too

I've been using this religiously for two years now - and have only just finished my second bottle! I have long, fine, straight, color-treated hair and this is a godsend. I use two pumps after I towel dry, and it makes my hair so smooth and silky, protects, the ends, and fights static and frizz. Plus, it smells amazing. My only complaint is the pump. It leaks if you try and travel with it. My solution is to pour a bit in another Birchbox hair oil sample container I received - and good to go!

Smells great, leaves my hair looking and feeling healthy, and is extremely potent. The product seems much more expensive than it is selling for and you only need a tiny amount!

I really like this - I try to wash my hair as infrequently as possible, and this is GREAT for my non-washing days to keep my hair smooth, shiny and looking well-conditioned. It smells great too!

two thumbs up from this dry-haired blondie! Not only did I like the smell of this product, I also liked the appearance that it had once applied throughout my hair. Instead of giving off a thick and greasy look, it shimmered with a healthy glow. A little goes a long way!

I love everything from No. 4. This is no let down either. Will buy again and again!!!

A little oil goes a long way!! Just finished this sample after almost 2 years of using a few drops 1-2 times a week. Buying the full product now- totally hooked. I use with a leave in conditioner and it’s the perfect combo of a bit of shine without being too heavy or greasy.

I have tried EVERY hair oil on the market! I have platinum blonde hair which can dry out very easily. Just a small dab is needed to improve the texture and shine in my hair. And the smell is intoxicating! You won't be disappointed.
