Works great. Hair was thinning on the sides. This helped to fill it back in. Pleasant smell. Would definitely buy again.

I like this Batana Oil it's not to greasy and it gives my hair a nice shine. I hope it helps my hair grow in the area where it is thinning. I will continue to use it to see if it thickens in these areas.

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!
