  • Smooth hair
Excellent product, I have tried multiple hair products to get rid of frizzy hair and this stuff works great. I also was having issues with hair loss but now I don't. This is the best, I also color m y hair.my hair is softer and it shines.I highly recommend buying this.

  • Smoothing
Great smoothing, soft & silky, smooths & tames frizz. Also great value for size & amount of oil that lasts longer than other oils.

  • Surprising results
I honestly did not expect it to work. When I go to the salon my hair is always shiny and smooth. I can NEVER achieve the results at home. When I used the product the first time I did not use enough or apply evenly.... So I thought my money was wasted. The next time I tried it I took a liytle more time and a little more product (bust still not much) and I fell asleep with my hair wet instead of trying it. When I woke in the morning I was shocked my hair was not frizzy (like it normally is when I sleep with it wet) is was instead shiny and smooth. The product works and makes my hair look like I just left the salon. And it does smell good. *please not that I am not a girly girl and suck at doing my hair. So if I can use this and have it work then it is EASY to use correctly. ... show more

  • Soft and thin
The media could not be loaded. I love this as it makes my thick hair soft and shiny! It is lightweight. It adds moisture without being greasy! It smells great and a little goes a long way so this bottle is a great value because it will last a long time

  • shiny and a nice scent
My hairdresser has used this on my hair for years; he just keeps forgetting to pick up a bottle for me. So, finally purchased off amazon (amazon has everything, right?) Anyway, works great, smells great. Best is to use on wet hair before styling. Love it.
