This study established a model of heat-damaged hair to assess hair care products, finding that daily hair drying for a month causes notable cuticle lifting, reduced mechanical properties, and increased protein release, and the model simulates even more severe damage.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

This study found that Eucommia ulmoides bark extract shows potential antioxidant and hair follicle-support properties in vitro and in vivo, but further validation is needed to confirm these effects.

This study reports that brief exposure to low intensity and low frequency ultrasound was able to transiently break cellular microtubules and mitigate hair follicle damage, suggesting a potential method to prevent hair loss during chemotherapy with taxanes like paclitaxel.

This study found that mixtures used in permanent hair dyes had irritant effects on reconstructed human epidermis, while individual ingredients alone did not.

This study documented that a CNN-KNN hybrid model achieved 98% accuracy in predicting hair breakage levels due to Telogen Effluvium, highlighting its potential for enhancing diagnosis and treatment in clinical dermatology through early detection of hair-related conditions.

This study explores torsional measurements of single hair fibers to differentiate the effects of cosmetic treatments on hair structure, highlighting their potential to reveal shear stiffness changes related to cuticle damage.

This study found that water-filtered infrared A radiation can induce the release of a model drug from gold nanoparticle-doped particles in hair follicles in an ex vivo porcine skin model, suggesting feasibility for follicular drug delivery systems.

This study reported that sunscreen with SPF50+ provides a high level of DNA protection against UV-induced damage in a reconstituted human epidermis model, comparable to that in skin explants.

In this study, researchers found that loss of OGG1 in a mouse model of systemic lupus erythematosus increased IFN-driven immune responses and aggravated skin lesions, suggesting a protective role for OGG1 in SLE skin disease.

This study found that laser hair removal is optimal for light to moderate skin tones using 10-15 J/cm² at 755 nm and for dark skin with 4.5-10 J/cm² at 755-1064 nm.

The researchers found that SPF50+ sunscreens provided the highest DNA protection against solar-simulated radiation in a reconstituted human epidermis model, with formulation type not affecting efficacy for a given SPF.

This study used molecular dynamics simulations to model the outer surface of human hair, illustrating complex behavior and potential adsorption interactions with fatty acids, which may inform cosmetic formulation development.

This study indicates that vitamin D3 administration may protect rat hair follicles from radiation-induced damage, as evidenced by maintained follicle numbers and increased Vitamin D receptor activity in treated skin.

This study observed that mice with a Cx43 mutation exhibited slower and asynchronous hair regrowth with severe cuticle weathering, mimicking aspects of hair phenotype in some ODDD patients.

This study demonstrated that combining l-cystine and thiamin in a formulation may protect against UV-induced damage in growth-limited human epidermal keratinocytes in vitro.

This study found that the CDK4/6 inhibitor palbociclib may protect human hair follicles from the damaging effects of taxane chemotherapy by inducing G1 arrest in stem/progenitor cells.

Hair styling products can damage hair over time.

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

This article discusses the mechanisms by which Cutibacterium acnes contributes to acne vulgaris and mentions potential triggers like UV light and tobacco, but it reports no new clinical results.

In this study, the researchers observed that post-radiation hair follicle repair in 3D architecture occurs through independent, long-range cell movements along the basal surface, resembling 2D healing processes.

This study suggests that male pattern baldness is primarily caused by heat stress in the brain rather than DHT toxicity, and personal experiments with menthol cooling have shown significant reduction in hair loss.

This study established a rat model of radiation-induced dermatitis using 90 Gy irradiation, which may aid in exploring new treatments and understanding the pathology, particularly highlighting autophagy regulation as a potential therapeutic target.

This study suggests that the synthetic peptide SPIKENET (SPK) may protect against long-term skin alterations in mice following coronavirus infection, offering potential therapeutic intervention for similar effects in humans post-COVID-19.

This study found that tenuazonic acid from Alternaria alternata can cause significant damage to vital organs in mice at low doses and highlights the need for regulatory measures to manage its risk in agricultural products.

This study defines classification criteria for hair follicle dystrophy using a mouse model of chemotherapy-induced alopecia, providing tools for standardized hair damage assessment.

In this study, researchers used a human skin organoid model to show that solar UV exposure damages hair follicles and skin, while exosomes from mesenchymal stem cells reduced inflammation and supported hair follicle regeneration.

This study found that DNA-damaged hair follicle stem cells in mouse models do not show typical senescent markers but are dynamically expelled to maintain tissue health and prevent hair loss.

This study found that oxidative stress in hair follicle melanocytes contributes to premature aging and apoptosis, providing insights into graying as a model for studying aging and testing antiaging therapies.

This study developed a humanized scalp model in mice which demonstrated that transplanted cultured human hair follicle dermal cells contributed to the restoration of damaged hair follicles.
