Strong coffee smell. Might not be be compatible for everyone. However, product is really good.
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
Love this product. May not be compatible for someone who doesn't like smell of coffee that does not detract from the product. it's really good for hair.

So far nothing amazing
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
So I’ve been using for a couple of weeks now and I haven’t noticed any difference. I am going to continue on. I don’t know if it takes time for it to actually show some results. I will say two things about it. It comes solid for 12 my jar cracked and broken And it’s non-returnable so I just have to deal with it so that’s unfortunate after paying $20 second of all it is a solid mass so you have to put it in your hands and kind of warm it up for it to become any sort of an oil and I wouldn’t even consider it an oil at that it’s more of like a cream once you warm it up in your hands, but it doesn’t make your hair greasy. I use a small amount I would think that the jar would last a long time given that you don’t need a lot to get through to your scalp unfortunately, with my jar being cracked, I don’t know how that’s gonna affect the longevity of the product And it does have a smell think of burnt coffee beans that will dissipate after about an hour to an hour and a half after putting it on, but if you’re not putting it on, I’m just going to bed. It might be become an issue. I’m gonna wait it out. I hope I do see results from doing this but again so far nothing.

Wonderful product
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I used this on a bald spot I had and it worked extremely well. Consistency is key though it needs to be used every day

It works and I love it!
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I love this product.. been using it for a few months now. My hair is more manageable and my thinning crown looks and feels fuller. The smoky smell, am not bothered because it disappears after a few minutes. I use it twice a week, massage very little amount on scalp and hair, then the next day wash it off with shampoo. I used to need to dye my gray every 3 to 4 months when some appear. Now, it's been 4 months since my last visit to the salon. I noticed my hair has darken a bit. I can delay my salon visit for another month unless I need a haircut!! Yehey!

Good moisturizer. Rich scent.
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
Raw Batana Oil provides goods moisturizing to hair and scalp and best applied with a little heat or steam. Pomade goes on easily once heated and does not feel heavy, greasy, or oily. Its rich fragrance eases on the nose after a short while. Difficult to say whether it is actually useful or whether it encourages hair growth. Leaves hair soft and easy to style.
