The smell.
It really does smell like coffee. Contrary to some of the comments, the coffee smell doesn't go away right away.
Waiting to see the results.

THIS STUFF WORKS!!!!!!
First of all - RUN, DON’T Walk & get this. IT WORKS!!! I kid you NOT, that I can literally feel sprouts of hair growing out of the roots of my head! After washing my hair And drying it, I part my hair into several sections and gently massage it into my scalp. After at least a day or so, I can feel the tickle in my scalp, it feels like grass slowly growing. I have plenty of hair, but I would love to actually see this product used on someone who doesn’t have hair like me. I am using the product because of a thinning spot that I have from a sew-in that I have had multiple times, and getting it parted in the same area for over a period of time. You can Not beat this product, especially for the price.

Don't not purchase!!!!
Color: A
This is product has over ingredients, its made in China and the shelf life is 3 years! No naturall product has a shelf life of a 3 years or any storing instructions. Just an FYI when buying any product, the ingredient that's the most in the product is the first on this list of ingredients WATER is the first, Batana Oil is second to the last. the packaging say 100%, 100% what? Its truely not Batana Oil. I am sending this back ASAP and working on my own mix for my hair growth. I am dealing with scared alopecia and have been searching for things to help with my hair growth. I am tried of companies thinking they will take my money. I was not able to see the ingredients until I recieved the package, which is not a terriable way to sell a product.
