This review highlights advancements in nanotechnology-based treatments for androgenetic alopecia, noting that these strategies could improve targeting and modulation of hair follicle environments compared to traditional therapies like minoxidil and finasteride, but also emphasizes challenges around safety, manufacturing, and regulation.

In this review, researchers examined advanced sensing technologies and bioelectronic interfaces that could improve understanding of the skin–brain axis, highlighting challenges and strategies for integrating these platforms into models for studying skin and neural interactions.

This review highlights recent advancements in nanotechnology-based approaches for treating androgenetic alopecia, focusing on enhancing drug delivery to hair follicles, controlled release, and follicular microenvironment modulation, while addressing safety, manufacturing, and regulatory challenges for clinical application.

This review highlights the lack of a comprehensive synthesis of stem cell therapy research by categorizing current studies according to medical specialty and stem cell type, while analyzing their advantages and limitations across various medical disciplines.

This study found that exosomes from human umbilical cord mesenchymal stem cells significantly promoted hair follicle growth and enhanced the transition to the growth phase in a model of androgenetic alopecia, by enriching specific microRNAs that activate key pathways involved in hair regeneration.

This narrative highlights a study underscoring that vitiligo and alopecia areata are complex autoimmune conditions, often misclassified as cosmetic, which can hinder patients' access to necessary treatments despite their profound impact on quality of life and associated comorbidities.

This study in Saudi Arabia found that 55.9% of participants reported premature graying of hair before age 30, with risk factors including genetic, health, and lifestyle aspects such as smoking, anxiety, nutrient deficiencies, and family history.

This review by two dermatologists suggests that hair on the human scalp may protect against skin cancer not just physically, but by enabling IL-17 immune surveillance, with hair loss potentially leading to increased tumor growth due to reduced immunosurveillance.

This review highlights that nanocarrier-based formulations, using both synthetic drugs and natural components, show promise in overcoming the limitations of current androgenetic alopecia treatments with modified release profiles and enhanced drug delivery, though clinical trials remain limited.

In this case report, a 39-year-old man with sudden whitening of scalp hair due to alopecia areata experienced total regrowth of pigmented hair after six months without systemic treatment.

This study demonstrates a significant correlation between anxiety, depression, and reduced quality of life in individuals with androgenetic alopecia.

This study identified a novel SCF mRNA splice variant in white merino sheep skin, which may play a role in hair follicle melanogenesis.

Using combined fat and growth factors can effectively treat hair loss after facial fillers.

This review discusses the increased incidence of hair loss and telogen effluvium among COVID-19 patients and evaluates existing evidence for regenerative treatments like PRP and HFSCs, finding limited published data.

This article describes a procedure involving skin marking, tumescent anesthesia, and micrograft mobilization, but does not present any study findings or results.

This review discusses recent research on the Dickkopf protein family's involvement in non-cancerous diseases and considers their potential as biomarkers and therapeutic targets without presenting new experimental results.

In this study, synthesized composite nanocarriers containing ribose and peptides demonstrated enhanced transdermal delivery, improved uptake by skin cells, promoted cell proliferation, enhanced antioxidant enzyme activities, and increased autophagy, suggesting a potential for more effective skin anti-aging treatments.

In this study on mice, elevated IGF-1 levels in the skin were linked to premature aging of hair follicles, but interventions like reducing IGF-1 or using senolytic treatments helped restore stem cell health and counteract aging effects.

This review highlights the critical role of mitochondrial dysfunction in hair loss, particularly androgenetic alopecia, and explores potential therapies targeting mitochondrial pathways to improve hair health, underscoring the need for further research in this area.

In this review, the authors propose that hair on the scalp may protect against non-melanoma skin cancer by maintaining an IL-17 biased immunosurveillance, with hair loss potentially increasing the risk of skin cancer due to disrupted immune monitoring.

This study reported that peanut callus extract, rich in resveratrol, significantly stimulated hair growth and reduced hair loss in an in vitro model and a clinical trial, showing promise as a cosmetic bioactive ingredient.

This animal study found that YH0618 may alleviate doxorubicin-induced alopecia and affects proteins like keratin and Smad3, suggesting potential therapeutic targets. The researchers analyzed protein expression changes to understand YH0618's effects in treating chemotherapy-related hair loss.

This systematic review found an increased incidence of hair loss and telogen effluvium among COVID-19 patients and reported preliminary effectiveness of platelet-rich plasma, adipose-derived mesenchymal stem cells, and human follicle stem cells for treatment without major side effects.

In this study, researchers found that high-shine and straight-aligned hair are perceived as more youthful, healthy, and attractive by women across various countries, with alignment having a stronger impact than shine.

This study reports that autologous micrografting may effectively treat stretch marks by promoting extracellular matrix remodeling and enhancing fibroblast activity, potentially expanding therapeutic options for this condition.

This study found that TLR2 and its ligand CEP are crucial for maintaining hair follicle health and stimulating hair growth, with deficiencies observed in aging and obesity potentially reducing regeneration.
