Compare your current hairline to older photos from the same angle and lighting
Look for a higher forehead than before
Check for thinning at the temples
Notice an M-shaped or widow’s peak pattern becoming more pronounced
See whether the hairline is becoming uneven or more sparse
Look for shorter, finer, weaker hairs along the front edge
Check for increased shedding on your pillow, in the shower, or on your brush
Observe whether your part is widening
Notice reduced density around the front and sides
Pay attention to scalp visibility where hair used to be fuller
Watch for a gradual change over months or years rather than sudden loss
Consider whether close family members have similar hair loss patterns
See a dermatologist if the change is rapid, patchy, itchy, painful, or accompanied by redness or scaling
