The user experienced rapid hairthinning on top of the head after two GFC treatments, despite using topical minoxidil for four years. Hair on the sides and back became thicker, leading to confusion and questioning of the treatment decision.
A user switched from finasteride to dutasteride to combat hairthinning but noticed overall thinner hair without shedding. Another user suggested that hair can't thin without shedding and recommended adding finasteride pills for peace of mind.
Hairthinning possibly due to rapid weight loss and dietary changes, with no nutrient deficiencies found. The user is taking vitamins and considering seeing a hair specialist to promote regrowth.
