Iron or vitamin deficiencies can lead to decreased hair diameter, not just androgenetic alopecia. Treatments discussed include Minoxidil, finasteride, and RU58841.
Microneedling with 0.6 mm needles combined with 5% minoxidil is more effective for hair count and thickness than minoxidil alone or with 1.2 mm needles. Biweekly microneedling at 0.6 mm depth is recommended for better results in treating androgenetic alopecia.
Dutasteride mesotherapy showed increased hair density and diameter without reducing serum DHT levels in a small study. However, the sample size was too small to make definitive claims about its efficacy.
A user has seen no progress after 8 months on finasteride and minoxidil and is considering switching to dutasteride and adding microneedling or quitting and getting a hair system. Another user suggests adding microneedling and dutasteride and buzzing the hair down.
A user experienced hair loss and thinning after starting a high-dose vitamin B complex. They are seeking advice on whether others have had similar experiences.
