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.

Mixed feelings
Sampled

I never tried a hair oil before so I don't have anything to compare it too.

But I do like the way it smells and it seems to give my fine hair a little bit of a shine. I applied to wet hair before blow drying; only a small difference it the way it feels, although not greasy at all (as I was expecting).

Honestly not a fan. Had to use, smelled weird and made hair appear unkept and unclean. I don't recommend.

Used a couple of times after showering and made my hair feel silky after using it. Also liked the scent.

Little bit goes a long way!

I love this stuff. My hair tends be dry and I use less than a dime size amount on my ends and work through my hair. If it gets in my roots it can get too oily. Adds shine!

The first thing I noticed about this oil was its scent; if it was a perfume, it would be a go-to. But the oil is so nurturing in my hair and doesn't feel heavy or slick--so nice for a curly girl! Not to mention I use it on everything that needs moisture. It's not just for hair! I put it on my cuticles and lips, too.

love this!

I have hair that gets oily easily but also damaged. I can use this every day and it doesn't make my hair greesy or heavy! it also keeps it nice and smooth after a blow dry! I have done hair and sometimes it gets poofy at the ends after blow drying, but this makes my hair look amazing! can't wait to get the full size!

I've never been two into hair oils beside this one Not Your Mothers that I've been using and love but this one felt very thin like it wasn't doing anything and I never noticed a difference with it

Great product!

Have tried a lot of hair products and love this one. My hair is fine but thick and gets tangely/frizzy and this worked really well but didn't make my hair greasy. Not the best smelling one I've ever tried but not bad either.
