The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This study found that a single ablative fractional laser treatment significantly reduced hedgehog pathway gene expression in microscopic murine basal cell carcinomas, nearly matching the effects of repeated topical vismodegib applications.

This case report describes a high school wrestler whose forearm rash was initially misdiagnosed as eczema, later identified as Majocchi's granuloma, and successfully treated with oral antifungal therapy after a biopsy.

This study demonstrated that ablation of individual somatostatin-expressing interneurons increased activity in nearby neurons of the mouse motor cortex during motor learning.

In this study, 13 androgenetic alopecia patients receiving Er: Yag laser treatment showed a significant increase in Staphylococcus spp. three days post-treatment, suggesting the laser may help modulate scalp microbiota balance.

This case report describes the first use of laser capture microdissection to confirm that atypical lymphocytes in a folliculotropic mycosis fungoides case involving the central nervous system were part of the same tumor clone.

This pilot study employed in-vivo multiphoton microscopy to visualize pigment-producing melanocytes in vitiligo patients, aiming to enhance understanding of treatment impacts and potentially improve transplantation therapies.

This study found that fractional laser treatment significantly enhances the penetration and targeting of certain permeants, such as imiquimod and FD, to skin follicles, but not hydroquinone.

This study found that the TrichoScan method detected significant increases in hair counts and cumulative hair thickness in men after finasteride treatment, suggesting its potential for monitoring hair treatment responses.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This study showed that ultrapulse carbon dioxide laser ablation can precisely remove rabbit skin without scarring, facilitating normal skin and hair restoration within one month.

This study presents the first reported case of woolly hair nevus appearing during adolescence, with significant improvement observed 5 years later and structural changes in the hair documented.

This review discusses the diagnosis and characteristics of dermatophyte infections and offers no new research findings, emphasizing the importance of microscopy and culture for accurate identification before treatment.

Laser hair removal might also work by damaging blood vessels around hair follicles.

This study found that combining liposuction with diode laser ablation was effective in treating axillary osmidrosis, with high patient satisfaction and no significant complications reported over a 10-month follow-up period.

In this study, red-light irradiation significantly increased hair follicle numbers and ATP levels in a mouse model, highlighting low-level laser therapy's potential to enhance hair regeneration and alter the skin metabolic microenvironment.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study documents dominant transmission and complete penetrance of uncombable hair syndrome in a family, despite the father lacking visible abnormalities.

This study reports that different animal species exhibit distinct hair scale patterns and elemental compositions, which can aid forensic investigations in identifying animal hair.

Er:YAG laser therapy effectively treats Hailey-Hailey disease, leading to long-term remission and improved quality of life.

This source highlights that fractional CO2 laser, as a minimally invasive technology, shows significant benefits in treating various skin and mucosal conditions by improving therapeutic outcomes, shortening recovery times, and enhancing precise personalized interventions through emerging technologies like AI and biomarker monitoring.

This study observed that undifferentiated matrix cells at the base of the hair follicle differentiate into the medulla, cortex, cuticle, and inner root sheath cell types through specific morphological changes.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

This study successfully cultured human fetal hair follicle-derived melanocytes, which showed high proliferative capabilities and unique morphological characteristics compared to adult-derived cells, potentially advancing hair disease research.

This study found that Hex gene expression patterns in chick embryo dorsal skin during feather bud development suggest a significant role in initiating feather morphogenesis.

This study found that somatosensory axons innervating Merkel cells in adult mouse skin exhibit significant plasticity, influenced by epithelial and neural factors, indicating a complex interaction in maintaining homeostasis.

This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.

This review discusses potential causes of alopecia and hair overgrowth in pediatric patients, detailing diagnostic techniques and treatments, but presents no new research findings.
