I'm doing a personal, one-year no-trimming challenge. It's been 5 months since my last trim, and I'm not going to trim again for at least another 7, when I expect to reach waistlength.
I really "baby" my hair, and as a result, hardly ever see a split end. I never use direct heat, moisturize my ends twice/day, never use a brush, and comb ONLY with a Jilbere shower comb, once/week, on wet, conditioned hair. When dry, I finger-comb only.
My hair is a little uneven, but that's no problem for me because I wear mostly updos and curly styles anyway. When I do decide to trim, I will get a "trusted" family member to do it.
