The place where hair is transplanted can change its growth rate and length but not its thickness.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This study reported that Panax ginseng extract significantly inhibited DKK-1-induced catagen-like changes in human hair follicles by promoting cell proliferation and reducing apoptosis, suggesting it may help mitigate hair loss associated with DKK-1.

In this study, researchers found that ginsenoside Re from Panax ginseng increased hair shaft length and duration in mice, comparable to minoxidil, by modulating TGF-β signaling pathways.

This study found that among Korean males with male pattern baldness, hair loss mostly progresses within 6 cm from the parietal whorl towards the occipital side.

This review discusses the roles of epithelial-mesenchymal interactions and dermal papilla in hair follicle growth and cycling, but it reports no new clinical results.

This review discusses the potential of cell-derived nanovesicles as innovative treatment strategies for hair growth and provides no new clinical results; the authors emphasize the need for further understanding of their mechanisms.

In this study, the herbal complex of Houttuynia cordata, Perilla frutescens var. acuta, and green tea promoted hair growth in C57BL/6 mice, enhancing regrowth and follicle development compared to controls.

Hair transplantation effectively treated a woman's patchy hair loss when other treatments failed.

This study identified aging-related epigenetic and transcriptomic biomarkers and suggested that curcumin might target and inhibit the JUN gene, implicating potential therapeutic strategies against aging.

This study found that 15-dPGJ2 promotes apoptosis in human follicular keratinocytes, suggesting its potential role in developing hair loss prevention treatments through DP2 antagonism.

This study found that Bacillus/Trapa japonica fruit ferment filtrate extracts enhanced human hair follicle dermal papilla cell proliferation through the Akt/ERK/GSK-3β signaling pathway, suggesting potential benefits for alopecia treatment.

In this study, hydrolysates of lactic acid bacteria were found to enhance hair growth in C57BL/6 male mice more effectively than 5% minoxidil.

This study found that hair diameter varies significantly within the occipital safe donor area, with thicker hair in the upper sections and thinner hair in the lower sections.

This article discusses the factors contributing to acne and reports no new findings, focusing on the role of sebaceous lipids and associated processes.

This study isolated a bioactive peptide from Trapa japonica fruit and found that it may protect human dermal papilla cells from DHT-induced stress, suggesting potential for biomedical applications.

This study found that a commercially available shampoo significantly increased hair counts and reduced hair shedding in Korean subjects with alopecia over 16 weeks.

This study found that using nanoporous silica entrapped lipid-drug complexes enhanced the solubility and bioavailability of dutasteride in beagle dogs.

In this study, researchers developed a new 3D skin equivalent assay using mouse epidermal and dermal cells that successfully regenerated organized hair follicles, outperforming a 2D model in hair follicle orientation and quantity, and enhanced hair growth when Wnt3a was added.

This study reported that the n-butanol fraction of Perilla frutescens extract, particularly rosmarinic acid, showed potential for hair regrowth and anti-androgenic activity in male mice, suggesting it as a possible treatment for androgenetic alopecia.

Light and temperature affect the daily skin function rhythms in hairless rats, with temperature influencing water loss but not skin hydration.

This study found that hair dyeing is more common among Korean women than men and among individuals with significant grayness, and it was not linked to higher scalp disease prevalence.

This piece discusses the benefits of head support during follicular unit extraction in a seated position and reports no new clinical results; the authors suggest an ergonomic support system to improve graft quality.

This article provides new treatment guidelines for AA based on expert consensus while integrating regional healthcare variations, but it reports no new clinical results.

This study found that among eleven tested polymethoxyflavones, 5-hydroxy-7,4′-dimethoxyflavone was the strongest steroid 5α-reductase inhibitor and suggests potential use for benign prostatic hyperplasia treatment.

This study successfully used noninvasive bioluminescence imaging to monitor hair generation in vivo after transplanting hair follicle stem cells in mice.

This paper reports a case of sebaceous carcinoma developing at the site of chronic candidiasis in a patient with keratitis–ichthyosis–deafness syndrome, without presenting new generalizable findings.

This study found that a specific fragment of AIMP1, secreted by hair follicle stem cells, activated dermal papilla cells, leading to enhanced hair regrowth and maintenance in mice.

This study observed that expanding regulatory T cells in the skin of mice with alopecia areata did not reverse the condition, indicating that additional immunotherapy may be necessary.

This study found that the trichogenicity of cultured human outer root sheath follicular keratinocytes decreased with longer cultivation periods and was significantly influenced by the expression of the transcription factor FOXA2.
