李东垣说：脉象弦而气虚，皮肤毛发干枯，头发脱落，用黄耆建中汤主治。头发脱落且脐下疼痛，用四君子汤加熟地黄。
朱丹溪治疗胡氏的儿子，年龄十七八岁，头发全部脱落一根不留，饮食起居如常，脉象微弦且涩，轻取重取都一样，这是因食用浓味食物导致湿热内生，痰浊停留在膈间，又因为每天多吃梅子，酸味收敛了湿热之痰，随着上升的气机到达头部，熏蒸发根处的血液，逐渐变得干枯，于是头发一时全部脱落。于是开具补血升散的药物，使用防风通圣散，去掉芒硝，仅将大黄三次用酒炒制，同时配合四物汤用酒炮制后混合调和，煎煮成小剂量的药液，用灰水兑入水中频繁服用。两个多月后诊察其脉象，湿热逐渐解除，停药，以清淡饮食调养，又过了两年，头发长得和以前一样而痊愈。甜瓜叶治疗人无头发，捣碎取汁涂抹即能生长。滋荣散、三圣膏。治疗头发脱落不再生长使其重新长出，麻子一升，炒至黑色，压榨出油，涂抹在头发上。《千金方》说：麻叶、桑叶两味药，用淘米水煮沸，洗头七次，头发可以长到六尺长。眉毛脱落，用生半夏、羊矢（羊粪）烧焦，等分为末，用姜汁调匀涂抹。又用七月采集的乌麻花阴干研为粉末，用生乌麻油浸泡，每晚敷用。乌麻，就是秋麻。
腋窝是指手臂下方与胁部上方的交界处，属于手厥阴心包络经。（朱丹溪说：手足阴阳合生见证曰，腋肿，涉及手厥阴、足少阳经）。又再归属于足厥阴肝经。（《灵枢》说：肝有邪气，其气停留于两侧腋窝）。腋前部属于手太阴肺经。腋后部属于少阴心经。腋下属部属于足厥阴肝经。腋下六寸处属于足太阴脾的大络。（《灵枢》说：脾的大络，名叫大包，出于渊腋穴下三寸，分布于胸胁。注：大包、渊腋都是穴位名，每个穴位左右各一。渊腋穴在腋下三寸凹陷处，举臂时取穴）。
Li Dongyuan stated: When the pulse is wiry and qi is deficient, with dry and withered skin and hair, and hair loss, Huangqi Jianzhong Tang (Astragalus Decoction to Establish the Middle) should be used as the primary treatment. For hair loss accompanied by pain below the umbilicus, Sijunzi Tang (Four Gentlemen Decoction) added with Shudihuang (Rehmanniae Radix Praeparata) should be administered.
Zhu Danxi treated the son of the Hu family, aged seventeen or eighteen, whose hair had completely fallen out without a single strand remaining. His diet and daily activities were normal. The pulse was slightly wiry and choppy, consistent in both light and heavy pressure. This condition resulted from consuming rich flavors, leading to internal heat and dampness, with phlegm turbidity lodged in the diaphragm. Furthermore, his frequent consumption of plums caused the sour flavor to astringe the heat-damp phlegm, which then ascended with the rising qi to the head. This steamed and scorched the blood at the hair roots, gradually causing them to wither, resulting in sudden total hair loss. He prescribed herbs for nourishing blood and dispersing upward, using Fangfeng Tongsheng San (Wind-Dispersing Universal Salvation Powder), removing Mangxiao (Natrii Sulfas), and stir-frying Dahuang (Rhei Radix et Rhizoma) three times with wine. This was combined with Sizhu Tang (Four Substances Decoction) prepared with wine, mixed together, and decocted into a small dose. It was frequently given to the patient mixed with water containing ash. After more than two months, upon re-examining the pulse, the heat-dampness had gradually resolved. Medication was stopped, and he was advised to maintain a bland diet for recuperation. Two years later, his hair had grown back to its original state, and he was cured. Sweet melon leaves can treat alopecia; crushing them to extract juice and applying it topically promotes hair growth. Zirong San (Nourishing Glory Powder) and Sansheng Gao (Three Sages Ointment) are used to treat hair loss where regrowth fails, stimulating new growth. One sheng of Sesame Seeds (Semen Sesami Nigrum) is roasted until black, pressed for oil, and applied to the scalp. The *Qianjin Fang* states: Boiling Hemp Leaves (Cannabis Folium) and Mulberry Leaves (Mori Folium) in rice-washing water, and washing the hair seven times, can promote hair growth up to six chi in length. For eyebrow loss, raw Banxia (Pinelliae Rhizoma) and Yangshi (Excrement of Ovis Aries) are burnt until charred, ground into equal parts powder, and applied mixed with ginger juice. Alternatively, Wuma Hua (flowers of black sesame harvested in the seventh lunar month) are dried in the shade, ground into powder, soaked in raw black sesame oil (Oleum Sesami Nigris), and applied nightly. "Wuma" refers to autumn sesame.
The axilla refers to the junction below the arm and above the lateral costal region, belonging to the Pericardium Meridian of Hand-Jueyin. (Zhu Danxi stated: Regarding manifestations arising from the combination of hand and foot yin and yang meridians, axillary swelling involves the Pericardium Meridian of Hand-Jueyin and the Gallbladder Meridian of Foot-Shaoyang). It is also associated with the Liver Meridian of Foot-Jueyin. (*Ling Shu* states: When pathogenic factors affect the liver, their qi stagnates in the bilateral axillae). The anterior aspect of the axilla belongs to the Lung Meridian of Hand-Taiyin. The posterior aspect belongs to the Heart Meridian of Hand-Shaoyin. The inferior aspect belongs to the Liver Meridian of Foot-Jueyin. Six cun below the axilla belongs to the Large Luo Vessel of the Spleen Meridian of Foot-Taiyin. (*Ling Shu* states: The Large Luo Vessel of the spleen is named Dabao, emerging three cun below the Yuanye acupoint, distributing across the chest and hypochondrium. Note: Dabao and Yuanye are acupoint names, each existing bilaterally. Yuanye is located three cun below the axilla in the depression; it is accessed by raising the arm.)
