Chao Yuanfang stated: The Foot-Shaoyin meridian is the channel of the Kidney, and its flourishing manifestation is in the hair. If a child has a congenital deficiency of blood and Qi in the Shaoyin aspect, the hair will be sparse, thin, or fail to grow. There are also cases where hair falls out and fails to grow due to head sores. All these result from 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 one tael).
The above herbs are crushed, sifted into fine powder. Then add:
Qushengzi (Semen Lepidii et Descurainiae, one he, ground) Hufen (Cerussa, half a tael, 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 scalp. Adjust dosage according to the child's age and size.
*Qianjin Fang* treats infants whose heads do not grow hair by crushing Qiu Ye (Folium Catalpae) to extract juice and applying it to the scalp; hair grows immediately.

*Benshu* records that Zengqi Shui (condensed steam water from rice steaming) promotes hair growth. Collect this water during cooking using a vessel, use it to wash the head to make hair grow thick, dark, and glossy. Although difficult to obtain in large quantities, frequent combing of a child's head gradually proves beneficial.
For pediatric white tinea capitis (Bai Tu) with hair loss, crush Ulmus mucosa bark (Yu Pi) into powder, mix with vinegar, and apply.
*Shenghui Fang* Shenxiao Heidou Gao (Miraculous Black Bean Hair-Growing Ointment) treats pediatric brain guan (Nao Gan), where hair falls out in tufts from the root, as well as sores, white tinea capitis, and failure of hair growth. It promotes hair growth in all these conditions.

First wash the head with rice water and soap pod decoction, dry, then apply. Use twice daily; hair grows within ten days.
Another formula:
Gegen (Radix Puerariae) Zhizhi (Cortex Porci) Yangzhi (Adipovis Ovis, each two taels).

Another formula: Take one sheng of Hemp Seed (Mazi), roast until black, press to extract oil, and apply to the scalp; effective.
