I was thinking about how my ends get raggedy despite treating them well now, and I realized that the ends are actually the hair that was on my whole head a few years ago. Back then, I didn't care about my hair at all. I wore braids and didn't moisturize and only used a conditioning shampoo. Then after the braids, I'd wear my hair out and blow-dried it every day... The hair was just damaged. I think most of it is gone now.
Anyway, I found a conditioner called Tio Nacho and have been applying it to my ends. They feel so soft.
