Poly-D,L-Lactic Acid Scalp Microinjection Protocol With Optional Light Microneedling Priming For Non-Scarring Alopecia: A Prospective Pilot Case Series

This laboratory study found that dendrobium officinale polysaccharide (DOP) stimulated hair follicle and hair growth in mice by activating the WNT signaling pathway.

In this study, the SFE-4 extract from coffee pulp demonstrated potential effects for treating androgenetic alopecia by enhancing cell proliferation and gene expression related to hair growth pathways in vitro, using human hair follicle dermal papilla and prostate cancer cells.

This review reports that clinical studies generally showed favorable results for microneedling as an adjunct therapy for androgenic alopecia and alopecia areata, despite the low quality of existing data.

This study found that microneedling monotherapy significantly increased hair count more than topical minoxidil in androgenetic alopecia, with combination therapy of microneedling and minoxidil being even more effective. Further research is needed to evaluate microneedling's safety and efficacy as a monotherapy.

In a mouse model of chemotherapy-induced alopecia, this study found that enhancing ETV2 expression improved angiogenesis and hair regrowth following 5-fluorouracil treatment.

This article reviews the classification, diagnosis, and management of hair disorders, emphasizing the role of trichoscopy and early diagnosis for effective treatment but reports no new clinical findings.

This study found that adding microneedling to minoxidil treatment significantly improved hair growth in men with androgenetic alopecia compared to minoxidil alone across all assessed measures.
