Smells so good
Size: 4 Fl Oz (Pack of 1), Unit Count: 4.0
I mix this with rosemary oil and give myself a treatment once a week. My hair is kinda dry as I age and this helps. I let it sit in a cap for a few hours then wash it out. It washes out surprisingly very easily and smells delightful!

Let's see how it works
Size: 4 Fl Oz (Pack of 1), Unit Count: 4.0
Much easier to use than the jar, I hope it works as well. After 6 weeks, Well my hair is exactly the same. No regrowth on my edges and my hair is not healthier. It’s just a basic hair oil. Will not repurchase

It works!
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
There is a strong smell or roasted coffee beans but since I started using this product my edges are healthier and the hair at the middle of my head that has been struggling to grow is gaining some length. The product itself can get hard depending on the temperature of your room but if you use it as directed the texture isnt so bad. The oil is thick and not very greasy or difficult to wash away. Definitely effective. 100% will recommend.
