My hair type is 4A, I started using JBC on May 1st to thick my hair and most of all my hair line. After a month of using my hair became very thick except my hair line that I still working on. I your problem is thin hair I recoment Jumaica Black Castor Oil Mix with Avocado oil or almond oil after a month you will see the difference. Mixed a table spoon on your daily rutine and massage directly on your scalve three time @ week. You will not regret.
