Characteristics of healthy and androgenetic alopecia scalp microbiome: Effect of Lindera strychnifolia roots extract as a natural solution for its modulation
August 2020
in “International Journal of Cosmetic Science”
TLDR Lindera strychnifolia root extract may help balance scalp bacteria and potentially reduce hair loss.
This study looked at the scalp microbiome of healthy individuals and those with androgenetic alopecia (AGA), a type of hair loss. They found that AGA subjects had an increase in Cutibacterium acnes and a decrease in Staphylococcus epidermidis, which may contribute to hair loss. The study tested the effect of a lotion with Lindera strychnifolia root extract on the scalp microbiome and found that it decreased the relative abundance of C. acnes and S. geniculata, and increased the abundance of S. epidermidis and Malassezia. Overall, the study suggests that the scalp microbiome may play a role in hair loss and that natural solutions like L. strychnifolia root extract may help modulate it.
