This review synthesizes findings from 15 animal studies on alopecia, identifying key biomarkers like TNF-α and IL-6 that suggest inflammation and follicular damage, offering insights into potential targeted therapies to balance degenerative and regenerative pathways for more effective treatment strategies.

This study found that exosomes derived from dental pulp mesenchymal stem cells (DPSC-Exos) significantly promoted hair regrowth and follicle density in a mouse model of androgenetic alopecia, showing similar efficacy to minoxidil by activating pathways that improve follicular vascularization and dermal papilla cell function.

In this study, topical red onion ethanol extract significantly restored cutaneous antioxidant and pro-angiogenic markers in UV-B-exposed rats, enhancing SOD and VEGF levels dose-dependently, but did not influence hair length, suggesting potential as an adjunct for hair photoaging.

This systematic review identified dynamic signaling interactions between hair follicle stem cells and lymphatic vessels, showing that these interactions coordinate hair follicle growth and tissue regeneration; enhancing lymphatic function may improve hair growth and present novel therapeutic opportunities for wound healing and hair loss disorders.

This systematic review suggests that interactions between hair follicle stem cells and lymphatic vessels are crucial for hair growth and tissue regeneration, offering potential targets for treating hair loss and enhancing wound healing.

This study found that Limosilactobacillus reuteri NCHBL-005, derived from honeybees, may promote hair growth via a novel non-androgenic mechanism involving the Wnt/β-catenin signaling pathway, as it increased hair follicle size and number in mice and influenced related gene expression in human follicle cells.

This study concluded that in female pattern hair loss patients, CGF and i-PRF treatments were more effective than PRP in increasing target area hair count, with i-PRF having the lowest adverse event rate.

This study found that Myrtus communis leaf extract significantly decreased IL-1α and increased VEGF gene expressions in human keratinocytes, which may relate to the plant's traditional uses for hair loss and wound healing, though further research is needed to explore these effects.

This study evaluated a novel synthetic cell-penetrating peptide, DualPep-ALO, finding it promotes hair growth by enhancing follicle cell proliferation, activating regenerative pathways, and reducing inflammation and oxidative stress in vitro and ex vivo, suggesting a promising new topical treatment for hair loss that rivals minoxidil.

In this study, Myrtus communis leaf extract significantly reduced IL-1α expression and increased VEGF expression in human keratinocytes, which the researchers suggest may be linked to its traditional use in treating hair loss and wound healing. Further investigation is needed to clarify its mechanisms.

This study found that perifollicular vascularization around the dermal papilla adjusts dynamically to physiological changes, with minoxidil enhancing vessel mobilization and aging processes inhibiting it, highlighting potential targets for treating hair loss and skin aging.

In this study, exposure to Myrtus communis leaf extract significantly reduced IL-1α expression and increased VEGF expression in human keratinocytes, which may relate to its traditional use for hair loss and wound healing; further research is necessary to understand its mechanisms.

This study found that Grateloupia angusta extract improved wound healing by promoting matrix production and pro-angiogenic activity in cell cultures and enhanced early wound repair in a mouse skin incision model.

This study found that a novel nano-engineered platform, PCA, significantly promoted hair regeneration in an androgenetic alopecia mouse model by enhancing angiogenesis and hair follicle stem cell proliferation, showing promise for future hair regrowth treatments.
