This review examines recent advances in androgenetic alopecia treatment, highlighting how multifunctional plant extracts combined with nanotechnology could improve topical therapy efficacy by enhancing local drug bioavailability and targeting, addressing limitations of existing treatments.

This study found that extracts from heterotropic cultures of Scenedesmus deserticola JD052 enhanced hair-inductive properties in human dermal papilla cells more effectively than photoautotrophic extracts, likely through activation of AKT/β-catenin signaling, despite similar loliolide content.

This review discusses the use of natural products in cosmetic preparations for skin and hair care, but reports no new research results.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This review suggests that allogenic adipose stem cell and extracellular matrix transplants may be safe and effective for various medical conditions, based on available studies.

This review summarizes the therapeutic potential and development of engineered extracellular vesicles for tissue repair and regenerative medicine, reporting no new clinical findings.

This study found that substance P may be involved in the pathogenesis of acne by increasing the expression of certain cytokines and receptors in cultured sebocytes.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This review discusses various plants and herbal formulations traditionally used for hair growth and notes their potential as safer alternatives to synthetic hair loss treatments, but reports no new clinical results.

This review examines complementary and alternative medicine for alopecia and finds limited support from robust clinical trials, highlighting the need for standardized studies to evaluate efficacy and safety.

This study identified several herbs, including Ganoderma lucidum and Urtica dioica, that showed promising 5α-reductase inhibitory activity suggesting potential use in managing androgenic disorders.

In this study, 1% procyanidin B-2 tonic significantly increased the number of total and terminal hairs on the scalp of male participants compared to a placebo after 6 months of use.

This study indicates that the Sp6 gene is crucial for the development of skin, teeth, limbs, and lungs in mice, possibly through regulating apoptosis.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

This review summarizes preclinical and clinical information on herbal products for hair loss treatment, highlighting their mechanisms, follicular penetration, and potential side effects, suggesting they may offer alternatives to synthetic drugs with fewer side effects.

This study found that Ganoderma lucidum extracts reduced prostate enlargement and improved symptoms in testosterone-treated rats, suggesting potential benefits for managing benign prostatic hyperplasia.

New method measures minoxidil concentration faster, more accurately, and automatically.
