a miracle in a jar
Scent: Earthy, Nutty, Refreshing, Size: 4.06 Fl Oz (Pack of 1)
This item did exactly what it was expected to do, and I couldn’t be happier with my purchase. It works as described, is easy to use, and the overall quality exceeded my expectations. The price was great for what you get, making it an excellent value. Everything about it—from performance to convenience—has been spot on. My sister has noticed an extreme growth in her hair since using this product. I’m very satisfied and would definitely recommend this to anyone looking for something reliable and well worth the money!

Not recommended
Scent: Earthy, Nutty, Refreshing, Size: 4.06 Fl Oz (Pack of 1)
Not the batana oil you should be buying. No this isn’t the one. Definitely don’t recommend it. It has no that coffee smell of the real batana oil and has extra chemical ingredients and makes it runny almost like a liquid oil. I made a mistake buying it.
