Many people in Latvia notice heavier shedding during the colder months. Heating dries the scalp, daylight is limited, routines change and stress can push more follicles into a resting phase.
Seasonal shedding should still have limits. If the part line widens, the temples keep moving back or the crown becomes easier to see, the pattern may not be seasonal at all.
A practical check starts with timing. Note when shedding began, whether it follows illness or weight change, and whether close relatives have similar hair-loss patterns.
The safest plan is to separate temporary shedding from androgenetic hair loss before committing to a transplant or long-term medication.
