Started experiencing dermatitis (and maybe it's also heat rash) about 6 weeks ago. Just discovered this website and have started following some of the advice (ACV, Biotin). At night when the itching gets bad I discovered two things that help. 1) Sensitive Skin Aloe Vera, and 2) Ice Packs. Just wrapped them in a towel and laid them on the itching area. This gives great relief.
