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.

Great oil
Sampled

The last hair oil I used eventually made me feel constantly greasy, so I was a little bit hesitant. But it did leave my hair soft and less frizzy.

Best I've Found!
Sampled

Number 4TM Fluoro5 Elixer works great with my wavy-curly hair. Before receiving this sample, I was fighting the frizz and losing the battle. No more losing to the frizz here!
Thanks BirchBox for the sample!

LOVE
Sampled

I adore this stuff. I get my hair done in about 10 mins, finish with this oil, and I'm ready to go with my hair looking bouncy and, most importantly for a girl with thick hair, NOT frizzy.

A little goes a long way
Sampled

I was very impressed by how much a little goes a long way in this hair oil. It doesn't leave my hair feeling greasy or weighed down. Though, I suppose if you over use this product, I can see how you'd find this very heavy. Not sure I'd purchase a full size seeing as this sample will last me a while.

Great to soften and smooth hair
Sampled

I really like this product. Unlike other serums, this doesn't leave the hair greasy or weighed down. It's a light oil that distributes itself evenly through hair and allows for bounce and movement. It has a light scent so it won't clash with other products.

Greasy hair alert!
Sampled

Be careful when using this product! I used a little bit and my hair looked so greasy and oily! I tried a second time with less product and it looked like I had a layer of grease on my hair. This one is not for me!

Smells amazing
Sampled

This product smells amazing! A little drop goes a long way. After you apply the product to your hair your hands aren't that oily-- which I love! The tiny sample will last a very long time.
