Herbal Medicine- Hair-Skin-Body -Nails 101

I participated in the latest challenge and still following the guidelines to healthy hair. My issue is that my ends are so dry and I see so much breakage when I comb and/ or brush through my hair. My regimen is 1. Wash hair on Sundays with matching shampoo and rinse out conditioner. Then follow up with a leave in conditioner and style with a foam. My style is usually flat twists or 2 french braids. I have been a natural since 2009 and cannot retain length. The longest my hair ever reaches is armpit length. My last trim was April but I am due for another soon. However, I won't be able to see my stylist until August so that is why I cut off about 2 inches all around due to the brittle ends. I am low porosity and have high sebum level. I need help with my hair because I feel hopeless.
