The ‘little black dress’ for hair: N.4 Flouro5 Elixer Restore & Repair Oil

Everyone needs a little black dress – it may not look like much on the hanger but it fits perfectly every time, conceals every flaw, and makes you feel fantastic when wearing it. I think we all also need a ‘little black dress’ for hair and my perfect fit that conceals all flaws and never fails to make me feel amazing is the N.4 Fluoro5 Elixer Restore & Repair Oil ($26).


The N.4 Fluoro5 Elixer Restore & Repair Oil is a thin, clear hair oil that can be used on damp and dry hair. I do both – I use one pump on my damp hair to repair split ends and radically decrease blow drying time, as well as eliminate static. Then, on day two or three (sometimes four…but don’t tell anyone) I add another pump for incredible softness and shine.

I have a lot of hair but the stands are very fine. I use most hair oils very sparingly because while silicones smooth my hair and make it soft, they also weigh it down so my hair looks flat and greasy. However, my little black dress hair oil never lets me down – it has Fluorosilicones but the oil is super lightweight so even if I go crazy and use two pumps, I never lose any of my volume. I just get tons of incredible shine and my hair feels like velvet.

I love how the N.4 Fluoro5 Elixer Restore & Repair Oil plays well with others. Sometimes I add it to other styling products like the N.4 Blow Dry Lotion or else the Super Comb Prep & Protect for a ‘cocktail’ and it always makes my hair look fantastic. And guys love this stuff as a beard oil. It really is the little black dress that looks marvelous on everyone.

The alcohol-free, clear formula works for every hair type, including fine hair. N.4 Fluoro5 Elixer Restore & Repair Oil is also 100% Vegan, Gluten Free, Sulfate & Sodium Chloride Free, Paraben Free. It has a very light scent with fragrance notes of white freesia, golden amber, and warm musk, but it quickly dissipates so even those who prefer no fragrance will be happy.

You can find N.4 online at and they have a handy store locator, too – I found 6 boutiques within a 50 mile radius of my tiny Michigan town, so it’s everywhere.  – Lisa

    I need this little black dress! I have used oils because my hair does look dull and flyaway, and they work. BUT as you say say they weight it down and in a day or two it does look greasy. Have to get this

    I have neither a little black dress or this hair repair oil. I really need both. I better get with it in 2020. Thanks for reviewing. My hair could really use this product.

    I am pregnant for the second time in 2 years…I feel like it has really taken a toll on my hair. Maybe this is just the thing I need.
