Dear Dr. Rassman,

I actually have a few questions, my first one is, can going tanning (whether in the sun or a tanning bed) cause hair loss and/or permanent damage to hair follicles?

My other question is, can seborrhoeic dermatitis cause permanent damage to hair follicles? Also, how long does seborrhoeic dermatitis usually last? I’ve been diagnosed with SD and I’ve
lost alot of eyebrow hairs and I’m curious as to how long I can expect this to go on for. Any help would be much appreciated.

Thank you.

The sun nor a tan should impact hair loss directly in the short term, but long term exposure to the sun can damage the skin to the depth of the bottom of the hair follicle. You need to be evaluated by a good doctor.

Seborrhoeic dermatitis does not cause hair loss. I’ve discussed eyebrow hair loss with seborrhoeic dermatitis before — Seborrheic Dermatitis on Eyebrows.
