I had terrible dryness and breakage issues with my hair and it all started when I started using henna. I chopped off the henna and now my hair is great. Im not telling you to cut but if I were you, I would consider halting the henna and upping your deep conditioning. Like the others said you may have product build up. So a good clarifying shampoo may be what saves your hair. Good luck!
