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.

I thoroughly enjoyed this Birchbox product I received.

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.

Love the scent

I. LOVE! the warm, clean, sandalwoody scent this leaves. My ends look shiny and it helps when brushing through tangles (even if it's not necessarily marketed as an all over detangler).

Love it!!

Once I am done with the sample I will buy the full size. It is very lightweight and definitely tams my hair and reduces frizz. I like to use it after a day of not washing- on my ends, and then dry shampoo at my roots.

I've ordered this twice.

This product is light weight and makes my hair so shiny. A little also goes a long way, making the price worth it.
