This review reports that while deep learning shows promise in diagnosing scalp disorders from images, challenges remain with data quality and model interpretability, suggesting that integrating explainable AI techniques is crucial for building trust and facilitating clinical adoption.

This study found that redhaired individuals consistently had higher calcidiol levels compared to non-redhaired subjects, suggesting a physiological adaptation for vitamin D synthesis in low UV-B conditions.

Advancements in biomaterials and nanotechnology are improving medical applications like hair growth, bone regeneration, and cancer treatment.

This paper summarizes the main findings presented in the plenary sessions of the British Journal of Dermatology, July 2004 issue, and provides no new research results.

This study found that human hair follicle dermal papilla cells grown in a 3D model influenced hair growth and immune pathways more effectively than those grown in a 2D culture.

This study found that scoparone increased the expression of certain pluripotency-related proteins in dermal papilla cells, suggesting a potential new mechanism for enhancing hair growth.

This study investigates the effects of Tenebrio molitor as a novel biomaterial for preventing alopecia and promoting hair growth, but reports no conclusive results.

This study reported that an ATRA-loaded nanostructured lipid carrier gel (ATRA-NLC-Gel) improved symptoms of alopecia areata in mice by enhancing transdermal drug delivery, reducing skin irritation, and promoting hair regrowth through targeted follicle enrichment and pathway activation.

This study suggests that the key mechanism of stress-related hair loss involves CRH-induced PTEN loss, which reduces autophagy and increases apoptosis in dermal papilla cells, highlighting potential therapeutic targets like PTEN activation or autophagy enhancement.

This study found that a hypoxic microenvironment enhanced the proliferation and pluripotency of adipose mesenchymal stem cells, promoting hair follicle formation and upregulating specific growth factors in Arbas Cashmere goats.

This research observed that Salvianolic acid B (Sal B) significantly promoted hair regeneration in vivo and in vitro, outperforming minoxidil in a mouse model of androgenetic alopecia, by activating Wnt/β-catenin and mTORC2/Akt pathways and upregulating MMPs and MAPKs.

This study found that hot water extract of Hydrangea serrata leaf and hydrangenol promoted hair growth by enhancing 5α-reductase inhibitory activity, stimulating dermal papilla cell growth, and exhibiting anti-inflammatory and anti-androgenic effects in cell cultures, mice, and human skin organoid models.

In this study, researchers reviewed the roles of autophagy and mitophagy in hair follicle cycles, exploring their potential links to hair loss and investigating how manipulating these pathways might offer new therapeutic strategies.

In this laboratory study, researchers found that human platelet-rich plasma (hPRP) significantly improved the proliferation and hair-inductive capacity of human dermal papilla cells (hDPCs) compared to fetal bovine serum, suggesting hPRP as a potential substitute for FBS in expanding hDPCs for clinical hair regeneration therapies.

This study demonstrated that culturing high-passage dermal papilla cells with specific supplemented conditioned media may preserve their hair-inducing abilities, suggesting potential for reconstructing new hair follicles in vivo.

This study highlights the versatility and potential of injectable hydrogel nanocomposites in biomedical research, emphasizing their roles in controlled drug delivery, tissue regeneration, and treatment of various conditions, such as cardiac issues, joint diseases, and bone regeneration.

This study reported that exosomes derived from human amniotic mesenchymal stem cells (hAMSC-exo) accelerated hair growth in androgenetic alopecia mice by enhancing signals between hair follicle cells and improving cellular environments, particularly protecting against dihydrotestosterone-induced damage via Wnt/β-catenin signaling.

This study found that DHA, a derivative of artemisinin, shows potential as a cosmetic ingredient due to its anti-aging, anti-hair loss, antibacterial, whitening, and anti-glycation activities.

This study found that lipids extracted from Schizochytrium sp. significantly enhanced the proliferation and survival of dermal papilla cells under oxidative stress, reduced reactive oxygen species, inhibited ferroptosis, and promoted antioxidant genes, which improved hair growth in experimental settings, suggesting a potential treatment for alopecia.

This study found that tectoridin, an isoflavone from Rhizoma Belamcandae, may stimulate hair growth by activating Wnt signaling in human and mouse cell cultures.

This study observed that exosomes from adipose-derived stem cells promoted hair growth by enhancing dermal papilla cell proliferation and activating signaling pathways, suggesting potential for treating immune-mediated alopecia.
