## Description

desertcart.com: Number 4 Hair Oil, Fluoro5 Elixir Restore & Repair, Anti Frizz Serum for Damaged Hair, 2.0 oz – N4 Hair Care : Beauty & Personal Care

Review: This is the best hair oil I’ve ever used and I’ve tried a ton - This oil is AMAZING! It’s a little pricy but worth every penny in my opinion. It smells so so so good. It doesn’t weight down your hair or make it look greasy. It gives the perfect amount of shine and helps with frizziness in the humid summer months and it gives a great amount of moisture during the dry winter months. A little goes a long way so I can usually make one bottle last like a year so even though it’s a little expensive, it’s not so bad when you realize how many times you can use it before needing more. I’ve been using this stuff for years. I originally got it in a subscription box, I think in Birchbox, and I immediately fell in love. If you’re on the fence about ordering, I say go for it. You won’t regret it!
Review: Worth every cent. - Best hidden secret to the most luxurious, soft, shiny hair. Serum is so light and spreads so nicely. The smell….is perfect!!! I use 2 pumps on damp hair then 1-2 more after done styling. A sale price would be nice though! ;)

## Questions & Answers

**Q: Is this  authentic products a not knock off?  Is it guaranteed authentic?**
A: I got a sample from birchbox that smelled better, had better consistency, and wasn't oily unlike the two bottles I bought from this site.  I'd say it was definitely a knock off.

**Q: Does this product smell like the conditioner?**
A: No it smells good but not like a conditioner.

**Q: Does this ever expire?**
A: There is no expiration date on the bottle but I suspect that a clear oil would have a longer shelf life than other products.

**Q: Is this a heat protectant oil?**
A: I don’t know if it protects against a hot blow dryer or curling iron. I would think it depends on your type of  hair. I have fine hair long.  I apply after blow drying to the ends  which guards against frizziness and makes my hair shiny and bouncy. That being said when I applied it on wet hair and tried to blow dry it I couldn’t get my vent brush  through my hair. I use It’s a 10 before blow drying which works well and costs less. Hope that helps.

### ⭐⭐⭐⭐⭐ My Favorite Hair Product
*by C***H on June 21, 2025*

I love this hair oil!!! I got it as a sample in a birch box YEARS ago. I just started using it again and it made my hair so soft and smooth. This product smells sooooo good too. Every single time I wear it I get compliments. I hugged my friend and he texted me later to say that I smelt good. I had no perfume on, just the hair oil. I also like how you can twist the top of the pump to lock it if you are traveling and are scared to get oil everywhere. When you pump the oil out, a good amount of product comes out. I found that I didn’t need to use that much. However, my hair has a slight wave to it and I found that when I use the oil, it seems like it makes my hair less wavy. I took a before and after picture of the oil. I was laying down and my hair was all frizzy, so I thought that would be a good example.
