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.

We love this stuff
Color: A, Color: A
My baby had an infection in his hair that he got once he started daycare. We tried everything to kill the fungus. It got so bad I had to take him to the doctor and they finally gave him some antibiotics and medicated shampoo. His head was so sore and tinder he didn’t want anyone to touch his head. So imagine trying to wash his hair everyday. The shampoo killed the fugus and took his hair out where it was. I purchased this product. IT REALLY WORKS!!!!!! We’ve been using it a few weeks and we definitely see a difference.
P.S I went and purchased the whole set

I like it
Color: A
I'm unsure how it affects hair growth since I've only had one jar. It does leave hair moisturizedand soft. It has a really nice scent.

Love this product!
Color: A
This really keeps the hair moisturized. Don’t use it too much because it causes build up. You can use as a conditioning treatment and wash it out or you can use it as a moisturizer.
