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.

Some oils weigh down your hair, but I found this oil to be lightweight and provide shine. It did not have too strong of a scent as well. I would definitely order the full size bottle.

Didn't wow me
Sampled

I didn't find this to be a particularly interesting product. I guess I'm a plain Jane when it comes to hair oil - I'm happy to use coconut oil treatments. If I'm looking for a gloss, I use a long-time favorite. I wouldn't switch to this.

My favorite Birchbox product!!
Sampled

I was excited when this came in my Birchbox because I needed some kind of product to use before blowdrying. My hair is long, thick, dark, and easily weighed down by too much product. I've actually stopped using conditioner because this oil does a better job! As other reviewers state, a little goes a long way and I do NOT use this around my roots. I put a little in my palm and run it through my hair (mostly the ends) right before blowdrying and it makes my hair SO shiny and soft. It doesn't weigh down my hair at ALL! I haven't had a haircut in over a year, yet I am constantly getting compliments on how nice and healthy my hair looks. I'm positive it's because I use this oil. Personally, I like the smell, but it's hardly noticeable after my hair is dry. I can see how this may not benefit those with very fine hair, but everyone else should definitely give it a try!

my fine hair doesn't need too much for it to look greasy. So this was a blessing as all I needed was a dime size amount to tame my frizz.

This is a good product. Reminds me of Paul Mitchell’s super skinny product. Nice smell

The perfect hair oil
Sampled

My hair is very fine, so anytime I add oil, I am risking a potential greasy disaster. However, this oil is great. It's very light and you only need to use a tiny amount for a nice effect. It helps reduce frizz and just made my hair "feel" better? Who knows. All I know is this oil is one of the only ones I have been able to use again and again.

Lots of use in one bottle
Sampled

Really do like this product. What I like most is that it only takes a tiny bit to work. However, this is also the reason I didn't give all 5 stars. If you're not very careful, too much will result in greasy hair. It really is a great product, when used correctly!

This oil was fantastic, I have fine/wavy hair and it never weighed my hair down even if it put a little too much on, and smells wonderful. I would use it right out of the shower when my hair was wet and after it dried, and my hair felt soooo soft. Great product!
