On the fence...
Will be updating review after I have used it for more than a week. But so far here are the pros and cons: Pros: Smells good Seems like a little goes a long way Easy to apply Cons: Not sure if this is because I didn't use Sulfate free shampoo, but felt like with one wash I didn't get all the product out of my hair, so when It dried, it still looked greasy/oily Will be washing my hair again with sulfate free shampoo, then will do another application in another day or so. it says to use 2-3 times a week, so I'll use it 3 times a week for 2 weeks and then come back and update my review. But so far, it seams like a good product and for the money, it's a fair value.

Great For Dry Hair
I've never tried Batana Oil before, so I had no idea what to expect. It's a great oil for my hair. I love that it is all-natural oil and is more like a paste. It spreads easily on my hair. I love that I can put a tiny bit on my finger and rub it directly into my dry scalp. The oil has an interesting but pleasant smell. It's hard to describe. It reminds me a bit of a cross between coffee and cacao, but more nutty and mild. I like it. It's not too strong. The directions say to apply and leave in for 20 minutes, then wash out with a sulfate-free shampoo. I like to leave it in my hair for a day or two before washing it again. It's a great conditioning oil for dry and damaged hair. It might feel heavy on fine or thin hair, but I like it on my medium-thick hair. The only reason I dropped this a star is that I'm dubious of the claim that it promotes hair growth. I think it helps my dry hair from breaking off, but I don't think it can do much for most hair loss. However, for hair conditioning, this is definitely a five star product.

Single-ingredient moisturizing treatment with a pleasant smell
When this is described as "batana oil," that's exactly what it is. Not a dozen other ingredients with just a little bit of batana, no colors or fragrances, just batana oil. I love that about this. It's easy to use, just melt it into you hands and massage it into your scalp and hair. Folks with long hair would do well to concentrate on the ends since that's where you're less likely to get natural oil from your scalp to help keep the hair healthy. Leave it in for a bit, then wash it off in the shower with shampoo. Not at all complicated. I loved how my scalp felt afterward, definitely less itchy and "tight." as far as regrowing any hair or anything, I think the only thing that would help me is a miracle, so I'm not basing my review on that. The smell is nutty and very nice. Similar to the roasty notes of coffee or chocolate. Very pleasant and not "chemical" or perfumey smelling.
