发乃血之余，枯者，血不足也。忽然脱落，头皮多痒，须眉并落者，乃血热生风，
风木摇动之象也。病后疮后产后发落者，精血耗损，无以荣养所致也。然须属肾，禀水
气，故下生。阴虚阳盛，则须白而有光，发属心，禀火气，故上生。劳心过度，则火上
炎而血耗，故发白而早落。所属虽殊，然乌须黑发，无出乎滋补精血二者而已。故《灵
枢》曰∶足阳明之脉，血气盛则髯美长，血少气多则髯短，气少血多则髯少，血气皆少则无髯也。

古一人登厕，被臭气熏触，隐忍良久，明日满面皆黑色，月余不散，相士断云∶不
出月必死。一良医令以沉檀香各一两，锉碎，安炉中，烧熏帐内，以被盖定，令病者
瞑目端坐，候香尽方可出帐，明日引鉴照之，面上黑色渐散矣。盖臭腐属水，香属
土，土胜水也。

Hair is the surplus of blood; dryness indicates a deficiency of blood. Sudden hair loss accompanied by an itchy scalp, with simultaneous loss of beard and eyebrows, is a manifestation of wind generated by blood heat, resembling the shaking of wind-wood. Hair loss after illness, after sores/ulcers, or after childbirth is caused by the depletion of essence and blood, leading to an inability to nourish. The beard belongs to the Kidney (Zang organ), inheriting Water Qi, thus growing from below. Yin deficiency with Yang hyperactivity results in white but lustrous beard hair. Hair belongs to the Heart (Zang organ), inheriting Fire Qi, thus growing from above. Overexertion of the mind causes Fire to flare upward and deplete blood, resulting in white hair and premature loss. Although their origins differ, there is no method other than tonifying essence and blood to darken the beard and blacken the hair. Thus, *Ling Shu* states: When the Blood and Qi of the Foot-Yangming Meridian are abundant, the beard is beautiful and long; when Blood is scarce and Qi is abundant, the beard is short; when Qi is scarce and Blood is abundant, the beard is sparse; when both Blood and Qi are scarce, there is no beard.

In ancient times, a person entered a latrine, was exposed to foul odors, endured it for a long time, and the next day his entire face turned black, remaining so for over a month. A physiognomist predicted he would die within the month. A skilled physician ordered Chenxiang (Aquilaria Resina) and Tanxiang (Santalum Album Lignum), each 1 liang, to be crushed and burned in a brazier inside a tent. The patient was covered with a quilt, instructed to sit upright with eyes closed, and allowed to exit only after the incense was consumed. The next day, upon looking in a mirror, the blackness on his face gradually dissipated. This is because foul decay belongs to Water, while fragrance belongs to Earth; Earth overcomes Water.
For women whose hair falls out easily and lacks luster: Use 3 Feizi (Torreya Seed), 2 Hutao (Walnut Kernel), and 1 liang Cebaiye (Platycladi Cacumen). Crush and soak in snow water, then use to comb the hair, making it lustrous and preventing fall.
