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.

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.

Best Shampoo/Conditioner I Have Ever Used
Scent: Nettle, Scent: Nettle
I purchased the Nettle Shampoo in hopes of getting my hair back to health after frying it off with bleach. I used it for the first time today and it is my favorite thing I have ever purchased for my hair. The smell of this is divine. I am not a sweet gourmand fan and this is just the most fresh scent I ever smelt I think. It honestly smells like a high end salon shampoo/conditioner duo. That is my favorite part about this product. Second favorite is that it actually does work soooo well! I put in quite a bit of oils and hair care before washing my hair and all of those oils were removed without leaving any waxy greasy feel to my hair. I was concerned it wouldn’t come out because this shampoo is 99% lather free. But it worked SO GOOD! It doesn’t feel dried out and brittle either. It’s just perfect I can’t stress it enough. 10/10 I wish there were more way I can say how much I adore this product. I have very fine hair by the way and it doesn’t weigh it down. I will keep using this and will update in maybe a month with pictures! Here’s the update: I used the shampoo and conditioner for idk probably a month. I’m not really sure. BUT I still absolutely love it. In the pictures I am going to attach, you can see that I had a decent amount of growth (the hair from the root that looks gray). My hair is quite oily after other hair care products were added so that’s why it looks the way it does. One more thing, the shampoo is very drying on the scalp I have noticed a little bit of dandruff and itchiness right after washing but I believe my scalp is getting used to it now because it’s getting less and less noticeable after every use. Keep in mind my hair had been chemically treated during the first week of use multiple times including bleach and box dye so that’s probably why it was irritated. I still absolutely adore the scent and the way it leaves my hair feeling light and clean and shiny and SOFTTT!
