In this study, the researchers found that the picosecond pulsed alexandrite laser (PSAL) may be as effective and safe as the Q-switched alexandrite laser (QSAL) for treating freckles in Chinese patients.

This study found that PES1CMU-defatted rice bran (DFRB) showed effective skin whitening and anti-aging properties comparable to standard treatments in cell models, suggesting its potential use in dermatocosmetics.

This study found that transgenic cashmere goats overexpressing thymosin beta-4 have a higher secondary to primary hair follicle ratio, suggesting potential for increased cashmere yield.

This study found that women with pilonidal sinus disease had significantly higher prolactin levels compared to women without the disease, suggesting a possible link to its development.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

This case study of a 50-year-old woman with myotonic dystrophy and multiple basal cell carcinomas suggests there could be a genetic predisposition for certain cutaneous tumors in such patients.

This study found that using an argon gas-based system for intralesional cryotherapy significantly reduced keloid scar volume, improved scar quality, and resulted in low recurrence rates after 12 months.

This study found that individual differences between pigmented and unpigmented hair fibers in Old Order Mennonites suggest grey hair may be perceived as drier and less manageable due to small mechanical and moisture changes.

This article reviews the impact of H2O2-redox homeostasis on hair follicle pigmentation via tyrosinase and associated mechanisms, discussing primarily findings from murine models without providing new clinical results for humans.

Minoxidil 5% caused skin discoloration in a man using it for hair loss.

This review explores recent findings on the regulation of the pilosebaceous unit and reports no new clinical results, emphasizing the emerging understanding of growth factors and steroid hormones in hair growth processes.

This study found that stable regeneration of pigmented hairs in mice after severe wounding can occur when the wound is made during the anagen stage, influenced by Wnt and Kit signaling pathways.

This study observed that pigmented casts are present in various alopecia types but are not specific to any single diagnosis, with distinct morphological features noted in trichotillomania.

This study found that minoxidil sulfate and pinacidil did not activate K channel currents in hair follicles, suggesting their effect on hair growth might occur through other mechanisms like increased blood flow.

This review discusses various treatments for pityriasis rubra pilaris, including vitamin A, methotrexate, and systemic steroids, reporting historical anecdotal evidence without new clinical results.

This article reviews the pathogenesis and treatment approaches for premature graying of hair, noting the unsatisfactory options currently available, and reports no new clinical findings.

This review discusses the effects of pregnancy on melanocytic nevi and reports no new clinical results; it suggests that changing nevi during pregnancy should be evaluated similarly to those in nonpregnant patients.

This study found that 82.3% of girls with anorexia nervosa had pili torti, an acquired hair defect, suggesting a potential link to excess vitamin A intake.

This study found that vanillic acid from wheat bran promoted dermal papilla cell proliferation, potentially stimulating hair growth by activating the PI3K/Akt and Wnt/β-catenin pathways.

Electrical impedance spectroscopy improves biopsy accuracy and efficiency for skin lesions.

This study found that genetic activation of Nrf2 in keratinocytes accelerates wound repair by enhancing cell proliferation and re-epithelialization, suggesting potential use for Nrf2-activating compounds in individuals with impaired healing.

This report describes a three-generation family with Cantú syndrome linked to a novel ABCC9 gene variant, featuring acromegaloid appearance and hypertrichosis without growth hormone abnormalities, and suggests a potential association with pituitary adenomas.

This study suggests that 3,4,5-tri-O-caffeoylquinic acid activates β-catenin to enhance pigmentation in mouse hair follicles, human melanocytes, and melanoma cells during the hair cycle's growth phase.

This study found that flavonoids with two hydroxyl groups in their B-ring, such as sterubin and luteolin, supported the regeneration of pigmented hair after skin injury, unlike those with one hydroxyl group.

This study found that those with pityriasis rubra pilaris reported worse quality of life than patients with most other dermatologic conditions, impacting daily activities and emphasizing its severe life quality implications.

This study reports that transplanted mouse hair follicles restored piloerection ability and connected properly with host tissues, suggesting potential for advanced hair restoration therapies.

This case study describes a 14-year-old girl with pili annulati who had fragile hair, which may be due to cavities within the hair shafts as seen in electron microscopic examinations.

This study found that topical pimecrolimus is as effective as clobetasol propionate for treating alopecia areata, with better tolerability in terms of side effects.

A benign tumor developed at a girl's BCG vaccination site, not previously linked to the vaccine.

This study reviewed the literature on pilomatrix carcinoma and reported that while wide local excision was the most definitive treatment, local recurrences and metastases were common.
