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.

A little goes a long way!!! Be careful not to go above 2/3rds of the way up the hair strand, or your hair will look super oily!

Not the way product, but not the worse. I'm
On the fence about buying it.

A little goes a long way! I use this just at the ends of my hair pre-blow dry for a soft frizz free finish.

Love it

It smells great! It makes my hair feel softer and look smoother/shinier. Wish the sample was a bigger size though

Great product

this is a really good product especially if you're like me & have thick, curly hair....just use a very small amount...it's quite heavy

I don't notice a difference with this product as opposed to not using it.
It would just be another addition to a long list of things to do and I didn't see any real results.

Okay unless you have fine hair

Us fine hair girls know that oils can be tricky and error on the side if only applying oil to the ends. Even with a tiny amount applying this all over the hair made it look greasy. I'm sure it's great for other hair types just not this one.

This was an AWESOME product! I had no idea that my hair could behave like this. I will DEFINITELY be buying this in the future and will sing its praises far and wide. Bonus features: it didn't make my hair oily (which I would have hated), and the glossy shine lasted for a few days after the first application. A major win in my book.

A little bit of this product, as with most serums, goes a long way. I use it on dry hair as a heat protectant when I'm straightening my hair and it works great. I've also used it when air drying my hair and have noticed a little extra softness. All around decent product.
