Mild Long-term Sun exposure cause baldness?

[hauss]

I have pretty short hair. I have no history of baldness in my family, but let’s say I exposed just the crown top of my head to mild sun for years upon years, but my hair protected the rest of my scalp, would I develop baldness in the exposed portion from cell damage? Let’s say that that spot is always a little bit red from the sun.

Thanks.

Androgens are the masculine class of steroid hormones that are made primarily by the testes but also by the adrenal glands and ovaries. Although the predominant thinking is that hyperandrogenism (increased androgen production) or increased sensitivity to androgens is the most dominant factor in hair loss, we do know that other factors like genetic predisposition, sun exposure, oxidant damage, estrogen levels, skin irritants, and prostaglandin (hormone-like substances) levels all play significant roles in the initiation and progression of hair loss.

So, is the answer yes? Could I have some affirmation on this statements credibility? I saw one other site that said that sun exposure didn’t get deep into the follicles because of the protection from hair, but what about people with really short hair? (I lost the other 3 sites I wanted to post :()

About how much sun exposure could cause enough damage to cause alopecia (is that the correct word?)?

Alec, welcome to the SDMB; I think you should know that what you may think is an innocent question can get you in trouble here.
