Number 4™ Fluoro5 Elixer Restore & Repair Oil

There was a time when we were a bit skeptical about hair oils—the last thing we wanted was a greasy, weighed down ’do. These days, however, we can't imagine a haircare routine without it. This strand-saving elixir gives drab, dull hair a coveted movie star shine (plus a whole host of reparative benefits). Our oil-free days are officially over.

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

Weightless Shine

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.

AMAZING.
Sampled

Let me start out with the scent of this product- it is intoxicating and I love it. My scalp gets very dry during the winter months and this soothes it on contact. I was surprised that upon applying it on dry hair it did not make my hair look oily at all but rather added volume and texture. I will definitely be purchasing this product.

Light--perfect for dry ends
Sampled

This oil is great. It reminds me of avedas dry oil which I have used forever, but this stuff has a bit more of a neutral scent. I have fine but thick hair with highlights around my face so my ends can get a little dry and brittle after heat styling. I finish it off with this stuff and it looks shiny and healthy again! And it will last you forever!

Not oily or heavy on your hair. Tames frizz in my wavy/curly hair.

Didn't notice anything

It seems that the days I've used this elixir, my hair became very staticky, and it was really hard to make it go away. This product smells good, but I didn't notice it doing anything positive.

A good consistency with easy spray - not a bad scent either!

Holds hair style well
Sampled

This hair serum works great. I was weary that it would make my hair greasy, but it didn't. Plus, it held my hair style in place all night. It's almost like using a hair spray, but without the stiffness. I'm very pleased with this sample!
