LOVE

This product is amazing. I use it when I blow out my hair as well as during the week on my ends. I color my hair so it gets super dry at times and thanks to this product, my hair looks so healthy and shiny! I had received a sample of it and am so happy I did. I LOVE it!

Bonjour Nadene, We are glad to hear you are enjoying the Fluoro5 Elixer Restore and Repair Oil! The minis are to love!

Awesome!

Gives my hair a fabulous shine while not making it feel heavy. I have been growing my gray out and looking for something to improve my hair's softness and decrease fly aways. This did just that!

Appalling customer service

I purchased this online. The package arrived soaked in oil - the bottle had leaked and was almost empty. I emailed and complained. They wanted photos. I sent them. They wanted me to return the empty damage bottle before they would replace it. I agreed to accept some mini samples because I couldn’t be bothered going to a post office whilst on holidays (I live in Australia but was in America on holidays). They said they’d sent my samples express international post. That was weeks ago but nothing has arrived and my emails go unanswered. DO NOT BUY ONLINE FROM THIS BUSINESS. THEY WILL RIP YOU OFF.
The photo shows how empty the bottle was when I received it.

Repair Oil

Adds the right amount of shine and not greasy. The smell is fabulous. Clean, and not overpowering. It smooths my cuticle down without weighing down my fine hair. Perfection!

  1. Michelle

    This frizz-fighting serum leaves my hair shiny, and soft without weighing it down. It also keeps frizz and humidity away when I’m traveling to humid places.

  2. Sparkle Tafao

    This products works amazing. I use this product on models daily and they love it. Their hair goes through so much damage from getting styled everyday for ad campaigns. This not only repairs damage, it also makes the hair texture feel silky and soft to the touch. Takes away split ends and gives the hair a healthy, shiny appearance.

  3. Kerri M

    I recieved a sample In my Birchbox , it was the BEST oil I have used , and I have tried dozens of extremely high end brands . No other product compares to this oil . I just purchased the full size . I am extremely impressed with the texture of my dry damaged hair ( I have asian black hair, and went blonde ) after using this oil . I’m in love with number4 products now .

  4. mrpurifoy

    I love, love, love this stuff. It does not weigh down. I really helps with shine and conditioning for my color treated, heat abused hair. 🙂

  5. Nick223

    Love this product. Soothes my hair without the oiliness.

  6. babyzelito

    Love this Fluoro5 Elixer Restore & Repair Oil. I always make sure to bring this wherever I go, travel or adventures. For me this is the best restore & repair oil for a damaged hair caused by too much heat from the sun.

  7. kla385

    I love this oil. I bought it as part of a kit through Birchbox and I will definitely repurchase when I run out. It really tames my frizzy hair and makes it so easy to style. My hair feels so smooth after using this product.

  8. emboog

    A little goes a long way and like so many N4 products, makes my color-treated hair soft and manageable. This is an investment product.
