Hair damage?

So I recently had my hair chopped and I LOVE it. I love doing these easy waves with my curling wand and leaving the ends straight. I’ve been doing the waves after I wash, then fixing them a bit with the wand for day two, and then I do a bun for day three.

My hair isn’t colored or anything and I use heat and breakage preventing serum. I’m not used to using heat tools too much but I love the style with this cut and for the first time, I can actually curl it a bit and have it only take 10 mins or so. But will doing this damage my hair very badly? Here is some pictures.☺️
