I've noticed some hair loss over the years, more in areas of the scalp where psoriasis built a house..... took over a decade to evict it. Hormone therapy has been helping me regrow my lost strands.

Yes!

Foods no. NOT treating the PsO and having untreated psoriasis on my scalp causes excessive hair loss. But when the psoriasis is under control, hair stops falling out and grows back

Hormone imbalance is the biggest reason for hair loss. Get them tested if you can and then look at the hormone disrupters in food and beauty supplies and plastic containers,

I noticed hair loss, might have been related to stress, or due to psoriasis (even though my dermatologist said my scalp looked ok), but she prescribed medication for it, and I seem to be losing less hair, but still not back to normal growth, and still get itching. Was told it could take up to 90 days for my hair to start growing back.
