秋冬防脱发避坑指南

Group 1 - The effectiveness of popular home remedies for hair loss, such as ginger application, is questioned, with claims lacking scientific support and potential harm to hair follicles [1] - Ginger's active component, gingerol, may temporarily stimulate blood circulation but can lead to irreversible damage to the scalp with prolonged use [1] - Black sesame seeds are believed to help with hair growth based on traditional Chinese medicine, but their benefits are limited to hair loss caused by nutritional deficiencies, not androgenetic alopecia [2] Group 2 - Popular hair growth products containing minoxidil are less effective than prescribed medications, as many over-the-counter versions lack sufficient concentration and purity [3] - Minoxidil is FDA-approved for treating androgenetic alopecia and requires continuous use for 3-6 months to show results [3] - Saw palmetto, a natural extract, is suggested to inhibit 5α-reductase, but there is no formal scientific evidence supporting its effectiveness against hair loss, and many products containing it lack proper certification [3]
