Great for hair growth
I love it so much, it makes my hair feel so soft when apply. After a few uses, my hair feels stronger and healthier.

Perfect hair growth oil
It really helps with frizz and doesn’t leave a greasy feeling. I definitely recommend it!

Healthy Hair Boost — Still Watching for Growth
Size: 4.05 Fl Oz (Pack of 1), Size: 4.05 Fl Oz (Pack of 1)
I’ve been using this Batana Oil for a little while now, and while I won’t claim any dramatic hair growth (but I started from a clean shave; so you be the judge), I will say my hair definitely feels healthier.
The texture is thick (more like a paste), so a little goes a long way. I usually warm it up in my hands before applying, and it spreads much easier that way. It has a natural, earthy scent.
What I have noticed is:
* My hair feels softer and more moisturized
* Less dryness, especially at the ends
* Overall looks a bit more nourished and stronger
As for hair growth, it’s growing at the same pace I think, but I do feel like my hair is improving in quality, which is a great start.
If you’re looking for a natural product to support healthier hair, this is worth trying. Just be patient and consistent!

Great Product!!!
Size: 4.05 Fl Oz (Pack of 1), Size: 4.05 Fl Oz (Pack of 1)
I’ve been using this Batana Oil for a little while now, and I’m honestly impressed with the results. The texture is rich but not overly heavy, and it absorbs nicely into my scalp without leaving a greasy buildup. After consistent use, my hair feels noticeably softer, more moisturized, and healthier overall.
One thing I really like is how it helps with dryness and adds a natural shine without weighing my hair down. It also seems to make my hair look a bit fuller, especially around thinner areas. A little goes a long way, so the jar should last a good amount of time.
The scent is mild and not overpowering, which is a plus if you don’t like strong fragrances. I’ve also had no irritation on my scalp, which is important for me with new products.
Overall, this is a solid product if you’re looking to improve moisture, shine, and the overall health of your hair. I’d definitely recommend giving it a try if you’re dealing with dryness or thinning.

This Batana Oil is an Amazing Product
Size: 4.05 Fl Oz (Pack of 1), Size: 4.05 Fl Oz (Pack of 1)
This is an amazing product. It moisturizes your hair and soothes your scalp. I highly recommend this product. It is rich but not too heavy. My hair feels so much softer and it feels so good on the scalp. My hair is shinier and healthier overall. Dr. Sebi Honduras found the right formula when he put this oil paste together.
