This study found that human scalp hair follicles transplanted onto chemotherapy-treated immunodeficient mice closely mimic chemotherapy-induced hair loss seen in cancer patients, providing a valuable model for research.

This study demonstrated that several botanical extracts possess antioxidant properties, reducing oxidative stress and lipid oxidation in scalp treatments, with rosemary extract showing potential to improve scalp condition in a 4-week consumer trial.

This narrative review highlights how scalp therapy can enhance service quality in barbershops by integrating trichology, aesthetics, and health education, potentially boosting client loyalty and competitive differentiation in the men's grooming market.

This study established a model using nude mice to successfully graft human scalp skin, maintaining hair follicle growth and skin integrity for at least two months, which may aid preclinical research.

This paper discusses two preclinical models for studying alopecia areata and finds that testing new therapeutic agents should involve both the C3H/HeJ mouse model and the humanized mouse model for comprehensive insights.

This systematic review of botulinum toxin for alopecia found inconsistent results on hair growth and highlighted the need for more randomized controlled trials.

This study introduces a hypothesis that elevated DHT at puberty may cause chronic thermal stress in specific scalp areas, potentially explaining Androgenetic Alopecia characteristics and guiding future research.

This study utilized U-Net's image-processing capabilities to achieve 92% accuracy in segmenting individual hair strands, enhancing early detection and reliable identification of hair fall areas, which assists in addressing challenges of subtle hair thinning that are difficult to see otherwise.

γδT cells can protect hair follicles from alopecia areata and promote hair regrowth.

This study developed a method for expanding human dermal papilla cells in vitro while maintaining their ability to induce hair growth, advancing the potential for follicular cell implantation as a treatment for hair loss.

No results are provided in this article as it lacks an available abstract, making it unclear what effects apremilast and tofacitinib have in a humanized mouse model of alopecia areata.

This commentary discusses the mechanisms of progression and potential regrowth in androgenetic alopecia, indicating that the initiation of anagen in kenogen follicles is more critical for hair density improvement than reversing follicle miniaturization.

This review examines preclinical studies on exosome therapy for hair loss and reports no new human clinical findings.

In this meta-analysis, researchers found that melatonin did not affect primary hair follicles or litter size in goats but was positively correlated with secondary follicle growth, suggesting potential relevance for studying hair growth mechanisms and human alopecia.

This study found that intermediate hair follicles respond to testosterone by growing, but do not respond to finasteride, suggesting they may provide a novel and clinically relevant model for hair growth research.

This study observed that while alopecia treatment in patients showed some improvements in quality of life and anxiety scores at six months, these changes were not statistically significant.

This study suggests that stress intensity is highly correlated with hairfall severity, highlighting the potential of an inexpensive and accessible machine learning approach for forecasting and prevention.

ChatGPT is more accurate at diagnosing hair disorders in lighter skin tones than darker ones.

This case study found that a 1.6cm ovarian Leydig cell tumor, causing hyperandrogenism in a postmenopausal woman, evaded detection on standard imaging techniques, underscoring the difficulty of diagnosing such tumors with imaging alone.

This study demonstrated that combining l-cystine and thiamin in a formulation may protect against UV-induced damage in growth-limited human epidermal keratinocytes in vitro.

This study found that ginsenoside F2 may suppress hair cell apoptosis and improve hair growth outcomes in a DHT-induced hair loss model more effectively than finasteride.

This study found that topical 0.05% betamethasone dipropionate was the most effective treatment for patients with patchy alopecia areata, with less than 25% hair loss, over a 12-week period, compared to other topical treatments.

This review highlights the benefits of long-pulsed Nd:YAG lasers for hair removal in individuals with Fitzpatrick skin types IV-VI, offering deeper follicular targeting with reduced melanin interaction, and examines emerging technologies like radiofrequency and RF microneedling for safe treatment options in skin of color.

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.

This review discusses the history and challenges of hair follicle regeneration using follicular fragments and dissociated cells, without presenting new clinical results.

This study developed an in vitro system to analyze human skin progenitor cells' ability to form hair peg-like structures, providing insights for engineering hair follicle organoids.

This study developed a three-dimensional model for studying hair follicle development, showing that immortalized dermal papilla cells retain certain differentiation activities and can induce tubule formation in vitro.

This case study found that multiparametric ultrasound can be an effective non-invasive diagnostic tool for evaluating scalp changes in alopecia areata following repeated corticosteroid injections, potentially offering an alternative to biopsy.

This article discusses scalp neuropathy in androgenetic alopecia and suggests that changes in tactile sensation due to Aβ fibers and increased nociception from circ-HTMR may be involved.

AI can accurately measure hair loss severity in alopecia areata.
