达菲辛 / Dafeixin

达菲辛 / Dafeixin is the professional hair-growth brand sponsoring 93.聊聊头发：秃了，就会变强吗？. The episode’s sponsor segment uses the brand to introduce [[Minoxidil|minoxidil]] and basic distinctions among postpartum shedding, stress-related shedding, chemotherapy-related shedding, androgenetic hair loss, alopecia areata, and other hair-loss patterns.

The wiki should treat Dafeixin’s role as explicitly commercial. The source can still contribute to Hair Loss And Follicle Cycle because it explains follicles, growth phases, and dosage cautions in accessible language, but brand and product claims should remain source-scoped and should not be converted into personal medical guidance.

• Product Led Willingness To Pay - distant business-adjacent concept; here the source is mainly content sponsorship, not a brand case study.
