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.

Awesome silky hair is the result from this product. Great for detangling and keeping hair lustrous and soft. Apply wet or dry. Smells wonderful.

I love this product. I have very frizzy curly hair that can be dry. When using this oil my hair feels healthy, shiny and smooth. I love it because the next day i have no residue and I can style and use this product.

LOVE IT!

I use 4-5 drops and rub it in to my towel-dry hair when it's feeling a bit dry. I have never had it leave my hair feeling oily, and it conditions beautifully. It's light enough to be used daily, but hydrating enough that when my hair feels dry I use it for maybe a week and then don't need anything extra for a month or so. I will definitely be buying a full-size.

Use regularly
Sampled

I love to use oils as part of my regular beauty routine and this product does it's job well. I put a little in my hair when damp and find that it doesn't get as frizzy when I blow dry, then I put a little in after it's dry just to smooth it down.

Nice smell and isn't strong, recommended for damaged hair
Sampled

This is without a doubt or any exaggeration the best product I've ever received from Birchbox. I have fine, straight hair that gets oily within a day, so I tend to shampoo often, which causes split ends. This oil is great for repairing damaged hair, and it really does give dull hair a nice shine. Other products I've used are too oily and leave my hair look greasy, but this gives it a shine while smelling nice.

Smells great! Helped smooth my wet hair out! Did not leave a horrible oil base to my hair once dry

Loved!

Loved this hair oil. It gave my hair shine and texture without making it feel oily. It reduced frizz and added the perfect amount of weight to give my hair a sleek look.

But I'm still passing most oils on to my sister--she loved it! I'm still a serum girl.

I have bleached thin hair...this product absorbed into my strands & repairs them! No greasy yucky.
