Zhangguang 101 was founded in 1974, and its products are dominated by the "Zhangguang 101" hair growth series independently developed by Zhao Zhangguang, the "father of hair growth" in China. Zhangguang 101 hair growth product, which once claimed to be "100% Chinese herbal care", was found to contain minoxidil, an unspecified western medicine ingredient, by the Health Sciences Authority of Singapore, although Zhangguang 101 responded that the minoxidil content was only 0.26%, but according to the dosage of 5-10 ml each time, it is also a very considerable dose. Since Zhangguang 101, which has been detected to contain minoxidil, is only for export, it is wiser to purchase other professional brands of hair growth serum to ensure the effect of hair growth.
 
Like most of the main Chinese medicine anti-hair loss products on the market, Zhang Guang 101 product is an anti-hair loss product with the goal of removing scalp oil, and its principle comes from the early Chinese medicine explanation of hair loss, the oil secretion is vigorous and clogs the hair follicles, the hair follicles lack nutrients and atrophy, and the hair falls out from the roots, which is called seborrheic alopecia. But now there is a more comprehensive and scientific understanding of seborrheic alopecia, oil secretion is a normal characteristic, the root cause of which is due to the combined action of androgen receptors and androgens (testosterone and dihydrotestosterone) on the hair follicle, which causes the hair follicle to be sensitive to androgens, and the hair follicle gradually shrinks under the action of dihydrotestosterone, resulting in hair loss, that is, androgenetic alopecia (AGA).
 
Zhangguang 101 has two hair growth liquids for the treatment of hair loss, the former is mainly composed of root extract, papaya fruit extract, gastrodia root extract and other Chinese herbal medicines, and the latter is mainly composed of ginseng, Sophora sophora, Salvia, gentian, Polygonum multiflori and other extracts, which mainly cleanse, nourish and balance oil on the scalp. However, there is currently no sufficient and reliable clinical trial data to prove that these ingredients have hair growth effects.
