Great product

I have used many hair products and they just didn’t seem to work for me until I watched hair tales and saw Issa Rae’s episode so I decided to try the products that she was talking about and I have loved them ever since. No other brands will be put on my hai as long your company keeps making products.

Best Hair Oil Ever!

I’ve discovered using this along with the detangler after shampooing, makes my scalp feel incredible and hair feels so soft I put a little on my fingertips and massage it into my scalp. Also a pea size amount and distribute evenly through my natural hair. With this I have noticed tremendous growth lately since I’ve been taking better care of my scalp. Love this oil! Not too light , but not overly heavy.
