I have not used TJ as a leave in but I love it as a co wash and mixed with honey for a rinse out. I used ACV rinse to help clarify and restore hair PH balance. I mix about 1 table spoon of ACV with 2 cups of water. I apply the mixture to my hair after I co wash or clean with a poo bar. Leave on for about 5 minutes rinse and follow with my conditioner or DT.
