This retrospective study found that adipose-derived stem cell-conditioned media increased hair density and thickness in women with female pattern hair loss over 12 weeks, with no severe adverse effects reported.

This study found that finasteride at 1 mg/day was the most effective dose for treating male pattern hair loss, with similar efficacy to 5 mg/day and better results than lower doses.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

This study found that dutasteride increased scalp hair growth in men with male pattern hair loss, particularly at a 2.5 mg dose, and was more effective than finasteride over 24 weeks.

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 review found that while topical minoxidil is effective for treating female pattern hair loss, finasteride showed no more effectiveness than placebo, and low-level laser therapy increased hair count but with inconsistent results.

In this study, finasteride treatment for two years did not significantly reverse miniaturized hair follicles in men with male pattern hair loss, challenging the "reversal hypothesis" as 79 out of 113 miniaturized hairs remained unchanged.

In this study, a computer-aided imaging system accurately measured the width of balding areas in female pattern hair loss, correlating strongly with clinical staging severity.

This study evaluated shaved style scalp medical tattoo (SMT) in individuals with advanced hair loss, reporting high patient and surgeon satisfaction scores.

This review discusses spatial and temporal patterns in animals, focusing on skin appendage organs, but provides no new research findings.

This study suggests that the AGA risk haplotype in Europeans was driven to high frequency by positive selection, likely associated with a variant in the EDA2R gene.

This study found that a combination of 5% hexane extract of Curcuma aeruginosa and 5% minoxidil slowed hair loss and increased hair growth in men with androgenetic alopecia.

This study found that male pattern hair loss worsened significantly after stopping finasteride, revealing a "rebound effect" where terminal hair transformed into miniaturized hair over 30 months off the drug.

This study evaluated the efficacy and safety of a 5% minoxidil topical foam without propylene glycol in men with androgenic alopecia.

This study found that finasteride treatment of male rats led to changes in their male offspring's testicular gene expression, potentially affecting sperm function in response to odorant-like signals.

This study found that both finasteride and low level laser therapy were similarly effective in improving hair regrowth for frontal pattern hair loss in men and women over a 3-month period.

This clinical trial found that the extract complex of Cistanche tubulosa and Laminaria japonica (MK-R7) significantly improved hair density and diameter in patients with patterned hair loss over 16 weeks.

In this study, researchers found that the shape of polygonal domains, such as squares and triangles, significantly impacts Turing pattern formation, with domain geometry affecting the stability and type of bifurcations observed in simulations.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

In this prospective cohort, baseline severity, disease activity, and relapse history were identified as key factors influencing response and recurrence in alopecia areata, suggesting that implementing standardized assessments could enhance risk stratification and personalized care approaches.

This study concluded that a polarized-light handheld dermatoscope attached to a digital camera is a practical and useful tool for diagnosing different types of alopecia.

Changing hairstyles can help hair regrow in children with hair loss from tight braids or ponytails.

This study aimed to identify trichoscopic features that help differentiate between tinea capitis and alopecia areata in children, enhancing diagnosis and treatment decisions visually and non-invasively.

This study reported that different types of alopecia have distinctive dermoscopic patterns, which aids in their diagnosis.

This review discusses various non-invasive methods for diagnosing alopecia areata, highlighting that trichoscopy signs like short vellus hairs and yellow dots are sensitive indicators of the condition, while advanced imaging techniques provide valuable information on hair follicle status and scalp inflammation.

This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

This article reviews the principles of donor and recipient dominance in hair transplantation and reports no new experimental results.

Hair transplantation in East Asians needs special techniques to ensure natural results and prevent complications due to their unique hair and scalp characteristics.

This study found that a testosterone patch and gel showed bioequivalent testosterone levels in hypogonadal men, but the patch mimicked a natural circadian profile, while the gel resulted in higher dihydrotestosterone levels.

This study found that among patients with seborrheic dermatitis, the "dandelion" vascular conglomerate observed through trichoscopy was correlated with Malassezia scalp colonization.
