My ends used to look like that until I went CG. Ie no sulfates no drying chemicals in my hair products. But the main thing that helped them get back to curly was moisture. I used a conditioner & leave in. Id put my conditioner on in the shower, pile it on top of my head, put a shower cap on & leave on for at least 5 minutes to let it really soak in. When i was done with my shower I'd scrunch the leave in with my hair flipped over right after the shower when my hair was still really wet. Then add my styler. Plop, then diffuse with my head flipped over. It took a couple weeks as my ends were sooo dry to get back to full curly but I noticed an improvement after every wash. I also got a deva cut and that helped a lot with overall better curl.
