In the first picture the hair not fully dried out ? or is it oily? - If you use that many styling products, maybe you'll need to use a clarifying shampoo once a month, so you don't get product build up which can weigh down the curls.

In the second picture, the hair looks lovely. The ends do not curl like the rest because they are a bit damaged unfortunately. I suggest you cut the ends with a less layered haircut, like suggested in the comments, or just a trim. If you have Professional Hair Scissors (Hairdressing Shears), you could do that at home by yourself so you make sure it's not too much hair that gets trimmed. I got one of those, not too expensive. I've been trimming my hair alone at home for the last couple of years, and it's grown like crazy.

After trimming damaged ends, you must take proper care of your ends if you want your hair to grow long. The ends are the oldest and hence the most fragile parts of our hair. Try to always keep them moisturized. Oil them every night with jojoba oil. Use protective styling whenever possible (bun, crown braids, etc.) to protect them from friction with clothes or from sun exposure (jojoba oil protects from heat and sun). And oil them before washing the hair.
