Mise-en-scène Curling Essence, a disappointing failure

I sometimes feel like my hair unravels quickly and gets damaged when I use a curling iron, so I purchased the Mise en Scène Curling Essence 2X Volume Curl from Amore Mall because it is affordable and ranks highly.

It has a thick texture, so it seems to last a little while, but maybe because the ends of my hair have gotten stronger, my back stings, and I feel like something is breaking out on my back after using it, so I can't use it often.

I think it would be good to use it only on days when you really need your hair curls to last a long time.
