Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

This study observed that the ethyl acetate extract of Equisetum debile showed high activity against 5α-reductase and lipid peroxidation with no cytotoxicity on dermal papilla cells.

This study found that the multifunctional FEA-PCEI dressing significantly accelerated wound healing, reduced scar formation, and promoted hair follicle neogenesis while providing antibacterial and anti-inflammatory benefits.

This study found that overexpression of antizyme in mice with activated MEK reduced skin tumor growth by inhibiting putrescine accumulation, slowing cell growth, and increasing G2/M transit time.

Revertant cell therapy shows promise for treating type XVII collagen deficiency, but better cell selection methods are needed.

This study found that p21 is much more highly expressed in normal melanocytes compared to melanoma cells, suggesting a potential target for preventing melanoma progression through cell cycle repair processes.

This study found that eribulin-based chemotherapy resulted in longer median progression-free and overall survival, with fewer side effects, for advanced triple-negative breast cancer patients compared to other chemotherapy options.

This study found that 830 nm LED light effectively treated post-inflammatory erythema and hyperpigmentation, while both 830 nm and 590 nm LEDs prevented post-inflammatory erythema.

This review outlines the genetic basis of GABEB, highlighting reduced type XVII collagen as a distinguishing marker from Herlitz JEB, and discusses potential therapeutic avenues without presenting new results.

This study found that Ber-EP4 immunoreactivity is present in specific areas of hair follicles across different stages of the hair cycle, particularly in the secondary hair germ, but not in mature anagen follicles.

This study presents a proof-of-concept for a hybrid electric vehicle power system using a high temperature PEM fuel cell as a range extender, which may offer increased energy density with a methanol/water fuel mix.

This study reported that EGFR inhibitor therapy in lung and head/neck cancer patients was associated with acneiform eruptions and severe skin dryness, which rarely necessitate discontinuation of treatment and can be managed symptomatically.

This study found that treatment with a 1550 nm fractional erbium–glass laser increased hair density and thickness in women with female pattern hair loss, suggesting it may be an effective and safe option.

This study found that the EpiLight Hair Removal System achieved approximately 60% hair removal after 12 weeks following a single treatment, indicating effectiveness and safety for long-term hair reduction.

ATR04-484 ointment shows promise for treating skin issues from cancer therapies.

This study presents the design of an autonomous bioregeneration chamber that aims to extend human lifespan to 130-150 years by optimizing biological and environmental conditions, suggesting that a longer healthspan is possible through technological, nutritional, and socio-economic interventions.

This study found that conditioned media from epidermal progenitor cells improved skin aging signs in a clinical trial and protected fibroblasts from oxidative stress in vitro.

This study found that 17beta-estradiol enhanced allergy responses in certain age groups of female mice and inhibited thymus involution and regeneration after contact hypersensitivity.

This study reports that ZD1839 (Iressa), an anticancer drug, was associated with acneiform eruptions and hair growth abnormalities due to its inhibition of epidermal growth factor receptor signaling in the skin.

This study found that topical eflornithine HCl 13.9% cream effectively reduced facial hair in women, with a favorable safety profile.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

This study found that adding topical eflornithine to hair laser treatment significantly reduced hair counts and inflammatory papules more effectively than laser therapy alone in treating pseudofolliculitis barbae.

This study evaluated the 308-nm excimer laser as an adjuvant treatment for frontal fibrosing alopecia and found it may stabilize hairline recession and improve erythema and perifollicular hyperkeratosis, with transient erythema as the only reported adverse effect.

This study found that immunohistochemistry can effectively distinguish between tricholemmoma and basal cell carcinoma, with BerEP4 and CD34 serving as key differentiators.

This study found that ectopic expression of the lymphoid-enhancer factor can induce K17 protein in the skin, suggesting a link between skin development and wound repair processes in mice.

This study found that type XVII collagen (COL17) regulates interfollicular epidermis proliferation in both neonatal and aged mice through Wnt signaling, suggesting its potential as a target for anti-aging skin strategies.
