This study introduces the PRECISE scale, a quantitative tool to classify androgenetic alopecia, aiming to improve planning and outcomes for hair transplantation surgeries by evaluating the whole hairless and thinning areas.

This study used multi-scale hybrid models to explore how signaling factors affect skin wound healing and embryo development, suggesting that different levels of fibrin clot density influence scar formation.

This study used high-resolution ultrasound to investigate the pathophysiology of persistent erectile dysfunction in young men who used the drug finasteride, observing differences in erectile tissue homogeneity compared to control subjects without finasteride exposure.

This study confirmed porcine PRP's commercial viability as a fetal bovine serum replacement, showing higher growth factor levels and stability, without increasing human follicle dermal papilla cell proliferation compared to FBS.

This study confirmed that porcine platelet-rich plasma could commercially replace fetal bovine serum due to its higher growth factor levels and effectiveness as a hair growth promoter comparable to existing serum.

This correspondence reports that some men with androgenetic alopecia can exhibit hair thinning patterns more typical of females, with variations observed between Australian and Korean populations.

In this study, a modified Sinclair scale was presented for evaluating hair loss severity in men with female pattern hair loss, outlining stages from normal hair density to severe hair loss while preserving the anterior hairline. Reliability data for using this scale was also included.

This study established and validated a visual scale to assess hair shedding in women with thick hair, finding it effective in distinguishing greater hair loss among women with female pattern hair loss compared to those without.

This study developed a novel multi-scale image descriptor using dictionaries for classifying histological images, achieving average recall and precision measures of 0.81 and 0.86 in identifying specific skin structures and pathologies.

This study found that a new 12-point scale provided a more precise measurement system for evaluating hair damage and improvement after hair care product use compared to a 5-point scale.

This study found that the modified FACE-Q scales are effective for measuring patient satisfaction after hair transplantation, showing increased appearance satisfaction and perceived youthfulness six months post-surgery.

This study developed an improved reference genome for the African spiny mouse using long Nanopore sequencing reads, potentially aiding future research into the species' remarkable tissue regeneration capabilities.

This review discusses the role of polarity signaling in coordinating tissue mechanics, micro-environmental functions, and cell fate decisions, but it reports no new results, highlighting the need for further study in mammalian models.

This study presents an improved reference genome for the African spiny mouse, which may aid in understanding its tissue regeneration at the molecular level.

This study found that alopecia areata was associated with an increased risk of hematological malignancies, particularly non-Hodgkin lymphoma, but not with solid malignancies, except in certain severe cases.

This study suggests that finasteride may inhibit the enzyme PNMT, potentially contributing to its sexual and psychological side effects.

This study evaluated donor area scars in hair restoration using a new assessment scale and found that most patients had good quality scars, with average scores of 15 or less out of 40.

This study found that hair follicles across mouse skin form a heterogeneous regenerative field, with distinct cycling dynamics influenced by the balance of activator and inhibitor signals, which could inform other organ regeneration research.

In this study, fish-derived collagen hydrolysate from tilapia scales improved hair growth and skin health in both cellular and mouse models, reducing oxidative stress and inflammation while enhancing hair quality and promoting beneficial gene expression.

This study found that in dogs with post-clipping alopecia, microneedling with platelet-rich plasma may induce more rapid hair regrowth compared to microneedling alone, though results were similar by six months.

This study developed a new semiquantitative grading scale for frontal and vertex androgenetic alopecia, which was found to be more sensitive and objective than existing classifications.

This study found that self-assessed mFG and Hirsuta scores have low specificity for diagnosing hirsutism in clinical settings, though they may still be useful for screening in epidemiological studies.

This article introduces the Progressive Loss (PL) Scale, aimed at helping physicians communicate the long-term cosmetic risks of hair restoration surgery to patients.

The document concludes that dermatology training and grading scales need to better represent dark-skinned individuals to improve diagnosis and assessment of skin conditions.

Mammalian hair scales change from smooth to wavy due to friction.

In this retrospective case–control study, researchers observed that patients with alopecia areata had a higher prevalence of iron deficiency anemia compared to controls, suggesting a potential comorbidity that may require assessment and management.

This study found that the Antera 3D® system provided an objective and sensitive method for assessing pediatric pathological scars, capturing significant changes in pigmentation, vascularity, and volume, compared to the traditional Vancouver Scar Scale and dermoscopy, which showed varied sensitivities across different scar parameters.

This clinical study found that Rosmarinum officinalis mother tincture significantly improved hair volume and density in individuals with diffuse hair loss by enhancing hair parameters measured through a hair shedding visual scale and ponytail thickness test.

A new reliable scale improves accuracy in measuring hair density and treatment response.

This study found that IBS is positively associated with psoriasis, rosacea, and urticaria, but inversely associated with acne and vitiligo.
