I do 50-50 anything over 95° I do not go outside, if I can help it and if I do go out it’s for short periods of time, no more than an hour. The itching in your scalp is from your sweat drying on your scalp a nice rosemary conditioner and I would say condition more than you shampoo and not hot water not cold water and let it sit rinse it out. My sweat has a tendency to make my eczema come out so after anything I’m doing outside and make sure to wipe down my face and neck and arm and later in the evening or when I’m done take a cool shower hot is not your friend,moisturizing your skin staying hydrated thick oil or thick cream nothing in a pumper bottle is usually sufficient my biggest helper taking Allegra. And then I also when I feel hot staying in the air conditioning and if you don’t have air conditioning than I thought a box fan attached to a cooler with ice in it. And wiping yourself With witch hazel

Stay in the house under the air

Oh my goodness, how I feel you. I have atopic dermatitis, and I suffer a lot with the heat. The sweat causes breakouts, so maintaining my daily bath regimen is essential (and during the summer, one can have a cool shower or two). I wear loose, light clothing, like tunics and dresses, but in the beginning I know I won't be great. However, as I start to get exposed to the sun, eventually all my eczema disappears. For the scalp, it's more tricky, do you get better if you just pass some water through your hair? Also, I think it would be best if you included some regimen before washing your hair, something that moisturises and cools. Peppermint oil has a cooling effect, aloe vera gel is hydrating and aids with inflammation, maybe add some glycerin to that? Try to see if there's a recipe like that somewhere, and if it doesn't work, try to adapt it, since everyone's skin is unique. Also, be careful with the dosage, as essential oils and glycerin can be irritant if used without a "carrier". I use Ricinus communis with just a bit of Rosemary essential oil before I wash my head and that works for me.

Great advice! I love using witch hazel.
