This case report describes two instances of naevoid bundle hair on the scalp, where multiple hairs group from separate follicles into a single sheath and show abnormal reactivity to keratin antibodies.

This study found that acanthosis nigricans in the knuckles correlates with higher insulin and HOMA-IR values, potentially serving as an early, accessible marker for insulin resistance even without excess weight.

Kv1.3 blockers may help treat alopecia areata and promote hair regrowth.

Certain gene variations in EGF and EGFR may increase the risk of alopecia areata in Koreans.

This article discusses the potential of low-dose naltrexone as an adjuvant therapy for trichodynia in alopecias, noting its anti-inflammatory properties and need for further research.

This review examines the use of microneedles for treating alopecia areata, highlighting their ability to enhance drug delivery through the skin by bypassing the outer barrier and promoting hair growth with minimal invasiveness.

This article describes a new instrument, the KD spreader, designed to help novice physicians perform follicular unit extraction hair transplantation with reduced trauma and operator fatigue, but it does not report new clinical results.

This study introduced a new laser-only method called EKA for acne treatment, which is reported to be safe, painless, and heat-free, showing promising results for both acne and scar repair in initial sessions without combining with LED light.

This study investigated Liquid Nitrogen Cryotherapy for alopecia areata unresponsive to standard treatments and found that three out of five patients exhibited excellent hair regrowth, with manageable adverse effects like pain and erythema, suggesting potential as an alternative treatment.

In this study, a woman's hair loss and physical condition reportedly improved with pharmacopuncture and needle-embedding therapy, but further research is suggested to validate these findings.

This study found elevated tissue levels of DKK-1 in patients with both androgenetic alopecia and alopecia areata compared to controls, suggesting DKK-1 as a potential therapeutic target for these conditions.

This study found that non-ablative fractional laser treatments in Korean patients had a low complication rate, with adverse events being temporary and not resulting in long-term consequences.

This study found that simultaneously inhibiting both KLK5 and KLK7 proteases completely rescued skin barrier defects in a mouse model of Netherton syndrome, suggesting both should be therapeutic targets.

This study shows that IKZF1 and the protein IKAROS may play a role in the development of alopecia areata, based on findings from both mouse models and human scalp tissues.

This case study from Ukraine describes a 5-year-old Akita dog diagnosed with sebaceous adenitis, presenting with pruritus, alopecia, and inflammation; treatment over 30 days led to complete restoration of affected areas, implicating potential heritability in Akitas.

In this case series, researchers reported an unexpectedly rapid and positive response to a topical, hydrogel-based botanical treatment for androgenetic alopecia in both male and female volunteers, achieving significant improvement in hair loss within 90 days instead of the planned 270 days.

ITK inhibitors may effectively treat alopecia areata.

This case report indicates that hair transplantation using follicular unit extraction can successfully treat hair loss at the nape of the neck caused by acne keloidalis nuchae.

This review highlights the importance of recognizing neoplastic alopecia as a potential indicator of underlying metastatic neoplasia, as it may be mistaken for other scalp conditions like alopecia areata.

This study suggests that an increase in kenogen phases, along with rising vellus hair cycles and fewer normal hair cycles, is associated with the progression of female androgenetic alopecia.

This source describes a collection of geometric medicine formulations aimed at comprehensive hair restoration and permanent hair removal, with claimed simulation results indicating complete baldness reversal and effective hair removal, but results are sourced from theoretical and simulation-based findings without reported clinical trials.

This document provides supplementary materials for a study on the efficacy and safety of a topical siRNA-based formulation targeting DKK-1 in treating androgenetic alopecia, but reports no new findings.

This case report found that a 48-year-old woman with idiopathic twenty-nail dystrophy experienced significant improvement in nail appearance after six months of treatment with oral Upadacitinib.

This study found that applying a formulation derived from Bacopa procumbens significantly promoted hair growth, pigmentation, and follicular cycle acceleration in mice compared to minoxidil, potentially offering a new therapeutic approach for hair health.

This study seeks to clarify the terminology and classification of keratoacanthoma and similar squamous cell carcinoma lesions with central keratin-filled craters to aid in accurate differential diagnosis.

This study found that the antimicrobial peptide DPK-060 effectively reduced bacterial counts of Staphylococcus aureus and was safe for topical use in preclinical models, although nanocarrier encapsulation did not enhance its efficacy.

This systematic review suggests that topical ketoconazole may improve hair regrowth and thickness in both animal and human studies for androgenetic alopecia, but further randomized controlled trials are needed.

This study reviewed the current state of intralesional therapy for keratoacanthoma, finding that while methotrexate, 5-fluorouracil, and interferon alpha are common agents, guidelines are still needed, and histopathological confirmation is advised to prevent misdiagnosis with squamous cell carcinoma.

This study developed a NIR light-triggered NO-releasing hydrogel that promotes angiogenesis, repairs damaged dermal papilla cells, reduces inflammation, and improves the nutrient supply and follicular environment in animal models, offering a promising treatment strategy for androgenic alopecia.
