经曰∶肾之合骨也。其荣发也。多食甘，则骨痛而发落。又曰∶女子七岁肾气实，齿更发长
；五七阳明脉衰，面始焦，发始堕。丈夫八岁肾气实，发长齿更；五八肾气衰，发堕齿槁。又曰
∶发髭黄赤者，多热多气；白者，少血少气；黑者，多血少气。美眉者，太阳多血，通髯极须者
，少阴多血；美须者，阳明多血，此其时然也。盖足少阳胆之经，其荣在须；足少阴肾之经，其
华在发。故气血充盛，发须黑而美；若气血衰弱，须发白而落。鲜能挽复于既衰之后，可以保护
于未败之前。人年三十外，常服补肾滋阴之饵，不致枯槁也。

《黄帝内经》说：肾与骨相合。其荣华表现在头发上。多吃甘味食物，会导致骨痛和脱发。又说：女子到了七岁，肾气充实，牙齿更换，头发开始生长；三十五岁左右（五七），阳明脉开始衰弱，面部开始憔悴，头发开始脱落。男子到了八岁，肾气充实，头发开始生长，牙齿更换；四十岁左右（五八），肾气开始衰弱，头发脱落，牙齿干枯。又说：胡须黄赤色的，多热多气；白色的，少血少气；黑色的，多血少气。眉毛漂亮的，是太阳经血液充足；络腮胡和下巴胡须浓密的，是少阴经血液充足；下巴胡须漂亮的，是阳明经血液充足，这是由经络气血盛衰决定的。大概足少阳胆经，其荣华表现在胡须；足少阴肾经，其荣华表现在头发。所以气血充盛，胡须头发就黑而美观；如果气血衰弱，胡须头发就会变白脱落。很难在已经衰退之后挽回，但可以在未败坏之前进行保护。人过了三十岁，经常服用补肾滋阴的药物，就不会导致枯槁。

As stated in the *Huangdi Neijing* (Yellow Emperor's Inner Canon): The Kidney corresponds to the bones, and its flourishing manifests in the hair. Excessive consumption of sweet flavors leads to bone pain and hair loss. It is also said: At the age of seven, a woman’s Kidney Qi becomes substantial; her teeth change, and her hair begins to grow. Around the age of thirty-five (five times seven), the Yangming channel declines; her face begins to wither, and her hair starts to fall out. At the age of eight, a man’s Kidney Qi becomes substantial; his hair grows, and his teeth change. Around the age of forty (five times eight), his Kidney Qi declines; his hair falls out, and his teeth become dry. It is further said: Beards that are yellowish-red indicate excess heat and Qi; white beards indicate deficient Blood and Qi; black beards indicate abundant Blood and deficient Qi. Those with beautiful eyebrows have abundant Blood in the Taiyang channel; those with full sideburns and chin beards have abundant Blood in the Shaoyin channel; those with beautiful chin beards have abundant Blood in the Yangming channel. This is determined by the timing of meridian Qi and Blood abundance. Generally, the Foot-Shaoyang Gallbladder channel manifests its flourishing in the beard; the Foot-Shaoyin Kidney channel manifests its flourishing in the hair. Therefore, when Qi and Blood are abundant, the beard and hair are black and beautiful; if Qi and Blood decline, the beard and hair turn white and fall out. It is difficult to restore what has already declined, but protection can be maintained before deterioration occurs. After the age of thirty, regularly taking tonics for Kidney Yin nourishment prevents withering.
