Red Panax Ginseng, also known as Korean Red Ginseng, has been shown to assist in increasing the number of human hair dermal papilla cells (DPCs) by preventing the programmed cell death (anti-apoptosis) of these cells (Park, Shin, & Ho, 2011). This property of Korean Red Ginseng is what allows it to promote hair growth.
In addition, Panax Ginseng is known to reduce blood pressure in a similar manner as the FDA approved drug minoxidil, allowing for Panax Ginseng extract to have similar rates of hair re-growth in test subjects as minoxidil (Kim et al., 2015). This study also showed that using the active components (ginsenosides) present in Panax Ginseng promotes hair re-growth at a rate even faster than minoxidil.
These results are similar to the ones found in a study of Panax Ginseng on Alopecia areata patients in Korea. (Oh & Son, 2012) This study treated twenty-five human test subjects with a combination of Korean Red Ginseng and corticosteroids and compared the rate of hair growth to a control group who were treated with only corticosteroids. The results of their study show that both hair density and hair thickness improved in test subjects treated with the Korean Red Ginseng and corticosteroid combination, while no statistically significant hair growth was seen in the control group.
They concluded that Panax Ginseng could be a useful treatment for people suffering from Alopecia areata. It is hypothesized that the anti-inflammatory and anti-allergic effects of Panax Ginseng found in the ginsenosides of the herb may be the cause of the hair growth seen in the patients.
It has been expressed however, that further studies of the basic mechanisms of Panax Ginseng need to be conducted in order to understand precisely how Korean Red Ginseng stimulates hair growth and how ginseng should be applied in order to stimulate hair growth (Oh & Son, 2012). More clinical studies should be also done against a minoxidil control group using both men and women in order to conclusively prove the hair re-growth properties of Korean Red Ginseng.

A patent for a green tea extract and ginseng extract has been filed by AE Amorepacific Corporation (Patent Number KR2015030095-A) that claims to prevent dandruff, promote hair growth, and to protect the scalp.
