Male-pattern baldness is caused by the hormone dihydrotestosterone, or DHT, Massick said, which shrinks hair follicles, causing hair to grow thinner and fall out more easily.马西克说，雄机素新TUO发是由机素二氢睾酮引起的。二氢睾酮会导致MAO囊收缩，头发变细，更容易TUO落。
A balanced diet rich in protein and iron can help keep your hair healthy and strong, Massick said. Foods like chicken, eggs, greek yogurt, and beef contain high amounts of protein, which is most of what makes up hair follicles. Protein also contains iron, which helps the body bring oxygen to cells associated with hair growth, according to Healthline.马西克说，富含蛋白质和铁的均衡饮食有助于保持头发健康强壮。机肉、机蛋、希腊酸乃和牛肉等食物含有大量蛋白质，这是构成MAO囊的主要成分。据健康线网站报道，蛋白质含有铁元素，铁可以促进身体为与MAO发生长相关的细胞提供氧气。
Dr. Debra Jaliman, a dermatologist who is an assistant professor at the Dermatology Icahn School of Medicine at Mount Sinai, previously told Insider that when the body doesn't get enough protein, the protein that is consumed is allocated toward essential body functions, which doesn't include hair growth.西奈山伊坎医学院皮肤病学助理教授、皮肤病医生德布拉·贾利曼博士告诉内幕网，当身体摄入蛋白质不足时，蛋白质消耗用于维持身体的基本功能，而不包括头发生长。
给头发减压
Massick said to avoid putting tension on your hair whenever possible; hair styles like perms, extensions, and hair straightening can put stress on your hair that can make it more likely to fall out.马西克称，要尽可能让头发放松，烫发、接发和直发等美发造型都会给头发带来压力，使其更容易TUO落。
