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.

This oil makes my hair feel shiny and renewed after using it! Sometimes it's the only product I use and it works great. I would recommend this product.

Lovely

I like using hair oils before I put my styling products on to help control frizz. This is nice and light.

An ok product
Sampled

I still have this sample and use it from time to time. I am not a fan of hair oil in general so I never buy it. I like this brand but I am not a fan of hair oil.

The BEST hair oil I have EVER used!
SampledPurchased

I LOVE this product! The first time I used it I received so many compliments on how shiny and healthy my hair looked. I have since ordered the full size bottle and it just keeps getting better!

Must have
SampledPurchased

This is my favorite thing I've received from BB. As I've gotten older my hair has started to get really dry. I've tried everything but this little product is a miracle. I just use one pump of it rubbed into my damp hair, and when it dries my hair is beautifully soft and silky. It has a light, pleasant scent. You don't need much and the bottle lasts a long time. Love it.

Great Product!
SampledPurchased

This oil makes my hair feel very smooth and shiny! I have long/fine hair that is normal yet gets naturally very oily throughout the day. This product surprisingly didn't make my hair more oily, but added just the right amount of moisture. Definitely use sparingly, and avoid the roots, unless you have very dry/frizzy hair.
I purchased the full size.

Would Pass

Pro: Smoothed down hair.

Con: There was no long term "restore" or "repair" to the hair. Also, the smell is in no way pleasant.

Nice

A nice, lightweight oil that makes my (straight) hair soft and my hair also air-dries better after I use this

Light oil

This oil gives a nice finish to dry hair, not as think as others.
