Chao Yuanfang stated: The Foot-Shaoyin meridian is the channel of the Kidney, and its flourishing manifestation appears in the hair. If a child has a congenital deficiency of blood and qi in the Shaoyin meridian, the hair will be sparse and thin, or fail to grow. There are also cases where hair falls out and fails to grow due to scalp sores. All these are caused by damage to the blood; when blood and qi are depleted, they cannot nourish the hair.
Qusheng Dan Formula (Zhang Huan) treats failure of hair growth.
Danggui (Radix Angelicae Sinensis, washed and dried by baking) Shenggan Dihuang (Radix Rehmanniae Preparata) Shaoyao (Radix Paeoniae Alba, each 1 liang).
The above herbs are crushed and sifted into fine powder. Then use:
Qushengzi (Semen Lepidii et Descurainiae, 1 he, ground) Hufen (Cerussa, 0.5 liang, finely ground).
Grind the above ingredients together until uniform, mix with refined honey to form pills the size of millet seeds. Take ten pills per dose, administered with decoction of black beans. It is also permissible to dissolve or apply topically on the head; adjust dosage according to the child's age and size.

*Bencao* records that Zengqi Shui (condensate from steaming rice) primarily promotes hair growth. Collect it using a vessel during rice steaming, wash the head with it to make hair grow dense, black, and lustrous. Although difficult to obtain in large quantities, combing a child's head every morning gradually proves beneficial.
