I had been using castor oil for years until I found this. This oil is just as thick and leaves my hair moisturized for an entire week without reapplying after wash day. I use to reapply castor oil two to three times throuout the week to maintain moisture on my hair and scalp, but I was looking to simplify my hair care routine. I now add black seed oil to thin it out a bit to get the right consistency, and I still don't have to reapply the oil. This is a great product, and I highly recommend buying.
