Batana oil 100%
Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1)
I have been using this batana oil in my hair and I really liked it. Leaves hair soft, with more shine and a healthier appearance. It feels nutritious without the need to use large amounts. It also helps control frizz and leaves the hair manageable. With constant use I have noticed that my hair looks stronger and more hydrated. Very good value for money.

Hair Growth Game Changer
Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1), Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1)
Game-Changer for Hair Growth & Thickness
I am seriously impressed with this 100% raw organic Batana oil. I’ve tried so many hair growth products, and this is one of the few that actually delivers real results.
Within just a couple of weeks, I noticed my hair feeling softer, stronger, and way more hydrated. The biggest difference for me has been in thickness—my hair looks fuller, and I’m seeing new growth, especially around my hairline. It also adds a really healthy shine without making my hair feel greasy or weighed down.
I love that it’s all-natural and unprocessed—you can tell it’s the real deal. A little goes a long way, so the jar will last you a while. I use it a few times a week as a scalp treatment and even on my ends to prevent dryness.
If you’re struggling with thinning, breakage, or just want healthier, longer hair, I highly recommend giving this a try. Definitely a staple in my routine now!

This product is helping my afro hair truly thrive!
Scent: Bright Coffee, Size: 2 Fl Oz (Pack of 1)
I've used this product for 1 month so far. Applying to my scalp, hair and the ends of hair approx 1-2 times per week. These are my benefits on my long afro hair:
- First off, my scalp doesn't particularly like oil on it, it would trigger itching, dandruff, etc., but it certainly loves this stuff.
- bald spots started growing back in.
- drastic reduction in hair shed.
- For a long while, I had difficulty retaining hair moisture. My hair is FINALLY getting the nourishment and moisture it needs and deserves.
- hair is noticeably softer and even more manageable.
- I detangled my entire head within 15 minutes the other day which is a first for me.
- Hair is thickening. Which in my opinion is because my hair is shedding less. Like my braids appear half an inch thicker than they were.
- Scalp stopped itching.
- Dandruff stopped.
As far as the scent goes, it smells soo good to me. i read authentic batana oil is supposed to smell like burnt coffee. Maybe it's just me but it smells like caramelized honey.
All in all I'm soo happy i was guided to batana oil because it has done wonders for me in such a short period of time. Very happy with my purchase and would recommend.

Thicker & Healthier Hair
Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1)
I’ve been using this Batana oil for a few weeks and I can already see a difference in my hair. My hair feels softer, thicker, and looks much healthier. The scalp oil keeps my scalp moisturized without feeling too greasy, and the natural formula gives me confidence that I’m using a quality product. I also noticed less hair shedding and better shine after regular use. The scent is natural and the mask is easy to apply. Great for both men and women who want stronger, fuller-looking hair.
