It's unlikely that the hormonal
disturbance is causing this. This certainly seems to be a skin problem to be addressed by a dermatologist
by having a look at the scalp
. May be with perimenopausal symptoms of hot flushes and excess sweating your face/ head skin is having irritation but if it turns sore then make sure it does not increase in size and general hygiene is maintained. Also do see an Endocrinologist
to consult when to stop the hormonal supplements and to get relief from the perimenopausal symptoms too. I hope this helps. All the very best.
