Number 4™ Fluoro5 Elixer Restore & Repair Oil Customer Reviews

Love it! I have very very fine, long, color treated hair, so I need a little extra strength/moisture and shine without weighing down my hair any more than usual. I've tried all sorts of serums and glossing creams and stuff in the past with usually average results at best - either I'm not getting the shine results I want or I look like a wet dog, all weighed down with goop. Bought a bottle of this on a whim since I've been such a fan of the other Number 4 products I've sampled, and I'm SO glad I did. This is it.

After a couple of uses, hair is exceptionally shiny and looks healthier than usual. However, my hair is NOT weighed down at all. If anything, it's moving more than usual. And it feels super soft. I'm hoping continued use does improve the health of my hair, but even if not I'd keep using this stuff based on looks alone.

I've been using this religiously for two years now - and have only just finished my second bottle! I have long, fine, straight, color-treated hair and this is a godsend. I use two pumps after I towel dry, and it makes my hair so smooth and silky, protects, the ends, and fights static and frizz. Plus, it smells amazing. My only complaint is the pump. It leaks if you try and travel with it. My solution is to pour a bit in another Birchbox hair oil sample container I received - and good to go!

I have super fine hair and winter drives me nuts. This hair oil smells great and did not weigh my hair down at all. It did help with my static when I applied a bit on to my dry hair as well.

I have an ombre effect on my hair so my ends tend to look dull unless I frequently treat them with something. I usually do a weekly hair mask which works great but its not something I want to do every day. This product is a great product to put on after I shower and even after I blow dry and straighten. I put a small bit in my palm and it really smooths my ends. It even adds a bit of shine. I would give it a five but the pump is of poor quality. One drop to the floor and it leaks now every time I use it. thats my only complaint.

This masque provides weightless shine! My hair is very thick but can get dull and dry, so it's great to have a masque to use every once in a while to revamp my shine. Hair feels so soft and fresh after rinsing! Great product.

This stuff is amazing! I use two squirts after I towel dry my hair, then another 1-2 squirts after blow-drying. It's never heavy, doesn't leave my hair looking greasy and gives my long locks plenty of sheen, silkiness and smoothness. The smell is great too and since it doesn't require a lot to get the shine you want, the bottle will last me a long time. Highly recommended!

This is a very light oil that doesn't weigh down the body in my hair but makes my hair feel so soft and look so healthy! It also doesn't make my hair look oily the next day. I'm sure this oil would be light enough for those with fine hair, as well! GIVE IT A TRY!

This product is amazing. I love how it makes my hair shine without causing it to be oily. It protects and makes my hair look amazing

I was excited to try this hair oil, but was disappointed. My hair gets oily easy so I only used a small amount, but it still greased up my hair. It definitely increased shine, but unfortunately gave it that greasy look as well. But as I said, my hair is very prone to becoming oily so this product may work extremely well for others!

I wanted to give this product 5 stars, because I love what it does. It's just for me, I didn't love the scent. Everything else aside, this is a fantastic product that does exactly what it says. My hair felt soft and hydrated. I have received items from this brand before, and it quickly became a favorite! Hoping to receive more from this brand.
