I think I have 3a/3b hair and I'm African American but everyone says they think I'm Hispanic because of the quality and thinness of my hair. I've been trying to grow my hair for year and I've recently started putting Jamaican black castor oil on my scalp and massaging it in everyday for 3 days. I also added some to my conditioner and it has made my hair softer. Does anyone have any other tips I can try? I'm fed up with my just barely shoulder length, thin hair. My goal is to have thick, full mid back length hair. And so far it seems impossible! SOS! Help! I've attached a picture on my hair currently and my goal.
