I got a trim Friday and my stylist told me that I have a lot of spots where hair is missing on my head (my husband likes to twist my hair and pull the knots out, that is the cause of this). She recommended that I try castor oil to rgrow the hair that I've lost. I want to know if others have had success with this and if I'm doing this correctly. I've read where you need to mix it with a thinner oil like olive oil and apply it to a wet head.
