This product did not work on my hair as it said it would
I have used this Product over three months and still haven’t seen a results, but I will order another one and see what happened with the second jar. My edges is still the same with no improvement? I was expecting a change since I read about it can grow ball spots. My edges is not completely ball but you can see a little hair there but as I use this products it did not help or change any length or anything my edges are still the same before I used the product it’s still the same after used it. I am so disappointed. Even though it didn’t help the first time I’m still gonna try it a second time just to make sure.

As seen on FB but cheaper.
I saw this advertised on FB. Much less expensive on Amazon. I have not used it long so I cannot provide how effective it is with growth. Some reviews have negative comments about the coffee smell. I didn’t notice this. However, my satin pillow cases did stain. Haven’t tried to wash so I cannot comment on the permanence.

This is Awesome and has no smell.
I absolutely LOVE this product. It has made my hair strong, longer and shiny. My edges are back, I've been using this for 3 months. I highly recommend Azure Batana Oil.
