Jamaican Black Castor Oil is a pretty good hair product. At first when I got it I was a little upset because I was used to a light oil. I applied this oil on my scalp and instantly my new growth became soft. I thought it could help my hair to grow, but I knew products don't grow your hair, a product can make your hair so manageable that you retain your length as it's growing out and a product that can do that is well worth buying. Since I do long stretches, I needed a product that could help with controling the new growth. Another thing I noticed about this product is that it causes a tingling on the scalp. I don't know if it's because it's the Rosemary blend. I found myself scratching my scalp often. I decided to do research and found out this happened with a lot of people and that the itchiness does go away. Lately my scalp doesn't itch like it used to, but my hair sure feels good. I might purchase this product again.
