    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.
