Adding topical minoxidil 5% to oral finasteride raised a hair growth index from 30% to 60% by initiating anagen. One PRP trial found hair density rose 12.8% over baseline. Another PRP trial found injections alone did not improve growth, and microneedling alone matched microneedling plus PRP. Scalp micrografts increased density by 23 hairs/cm². Botulinum toxin A injections were measured for effectiveness and safety. Oral dutasteride raised hair count more than intralesional injection, though route comparison was unreliable. Saw palmetto supplements showed modest benefit with limited high-quality evidence. Exosome therapy was reported to promote hair growth, though clinical trials were lacking. PRP with microneedling and concentrated growth factor was reported to reduce shedding and raise hair count. Combining beard and body hair grafts improved visual density in advanced baldness. Spanish dermatologists' prescriptions of oral dutasteride and oral minoxidil rose sharply since 2017.
