We asked Kristina Goldenberg, M.D., a dermatologist and cofounder of Goldenberg Dermatology in New York City, to shed light on the scalp-heat connection.
What does consistent heat stylingg do to your scalp?
Repeated exposure to heat styling can burn the scalp and damage hair follicles. This may lead to scarring and even permanent hair loss.
Can it make skin conditions like eczema and psoriasis worse?
Absolutely. If heat styling causes a burn to the scalp, skin cells can get damaged and flake off like dandruff. Patients with psoriasis may find their symptoms are exacerbated, because localized heat generates inflammation.
What’s the maximum number of times per week to blow-dry?
Once or twice a week is best, depending on your hair’s health. Start with a lower heat setting, increase slowly, and use a brush with widely spaced bristles, which disperse the air.
