September 2014 in “Biological Research” This study found that arctiin, a compound from Arctium lappa, demonstrated protective effects against oxidative stress-induced dysfunction in human hair dermal papilla cells, suggesting potential therapeutic use for alopecia.
November 2020 in “bioRxiv (Cold Spring Harbor Laboratory)” This study in live mice suggests that hair follicle regression involves apoptosis propagation towards stem cells, potentially slowed by a protective signal from the stem cells themselves.
