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.

How does the reviews when I purchased go from 4.7 to 4.5 meaning it’s not a good product, therefore wasted money

Nice Scent but Too Early to See Results
I’ve just started using this batana oil, so it’s too early to say if it actually helps with hair growth or thickness. I’ll need to use it consistently for a while before seeing real results.
So far, I do like the smell—it has a nice scent and doesn’t feel overwhelming. The oil itself feels nourishing and easy to apply to the scalp and hair.
The size is decent for the price, but like most hair treatments, the effectiveness will really depend on long-term use.
Pros:
Pleasant scent
Feels nourishing on hair and scalp
Easy to apply
Cons:
Too early to tell results
Overall, it seems promising, but you’ll need to give it time to see if it actually delivers on the hair growth claims.

Great batana oil for hair
Banana oil is so incredible, I will never stop singing its praises. I am prone to dry scalp and have thin, curly hair that needs just the right amount of moisture or it will frizz out. Batana oil has helped restore balance to my scalp and reduced flakes and it adds just enough moisture to my hair. This oil is a great version. It is thick, but not so thick that it doesn't melt in your hands if you rubs them together. I also have not noticed any stickiness or excessive left on my hands that can happen with some Banana oil brands. I do want to note that I usually put the batana oil on my scalp, let it sit for 15-20 minutes then wash it out, if you are going to let it stay in your hair, this may be too heavy for you. Otherwise, a great deal at the list price of $14, since a little goes a long way.
