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.

Great oil!

I love this oil. I use it after Dew Magic and before applying styling cream /gel. I get great first day hair. After that, I apply it to my ends and the back of my hair (which always seems frizzy and flat) at night before pineappling and I always wake up with beautifully moisturized and bouncy curls. For reference my hair is a mix of 2c, 3a and 3b curls that are very dry due to environmental stressors and going grey.

GO BUY IT RIGHT NOW!

This product is actually brilliant. I have extremely low porosity 3c hair that won't absorb ANYTHING. I have tried every brand and every product out there. Something about this serum is unique it absorbs into the hair without using a lot and it doesn't leave my hair greasy it goes into the strands and makes the hair more malleable and less brittle . I wash my hair then put the serum then detangle and then some gel then diffuse. I threw out everything else I own. I only have this and gel in my hair product collection. If they discontinue this I'll just have to wear wigs or something till I can find something that works this good.
