This review discusses the mechanisms behind alopecia areata and primary cicatricial alopecia and reports no new clinical results, aiming to guide the development of targeted treatments.

In this cadaveric study, lipofilling was found easier to perform on the face than the scalp, whereas nanofat grafting was particularly suited for precise injections in scalp areas, suggesting a combination of techniques could aid in treating alopecia.

This study found that trichoscopy is an effective noninvasive technique for diagnosing frontal fibrosing alopecia, confirming its valuable role alongside traditional histopathological examination.

This study reports that a third of patients with SARS-CoV-2 infection developed acute telogen effluvium within three weeks, highlighting a notable pattern of early hair loss following COVID-19.

This study found that in alopecia areata, treatment with the oral JAK-inhibitor tofacitinib decreased clonally expanded CD8⁺ T cells in the scalp, but many expanded clones did not completely disappear, potentially leading to relapse after stopping treatment.

This open-label study found that oral tofacitinib led to significant hair regrowth in patients with moderate-to-severe alopecia areata, supported by changes in gene expression and T cell dynamics.

Finasteride and dutasteride can increase beard thickness in men.

In this study, distinct molecular mechanisms of action were identified for three drugs used in alopecia areata clinical trials, providing insights for precision medicine and treatment selection.

This case study identified the condition as Monilethrix in a 17-year-old female, characterized by a beaded hair appearance and linked to a genetic cause.

This article reviews the National Alopecia Areata Foundation's biennial research summits, aimed at advancing treatment development for alopecia areata, and reports no new results.

This study found distinct gene expression profiles in the parietal and occipital scalp of individuals with androgenetic alopecia, linked to developmental origins and susceptibility to hair loss, offering insights into genetic and epigenetic factors involved in AGA.

In this study, a daily low-dose regimen of oral minoxidil and finasteride over 12 months led to significant hair density improvements in over 92% of adult men with androgenetic alopecia, including those with advanced stages, though inter-rater reliability in photo assessments was modest.

This article discusses SARS-CoV-2-induced telogen effluvium in a multicentric study and reports no new clinical results.

This study found that a genetic test using 5 to 20 SNPs can predict male pattern baldness with variable accuracy in European men, especially those aged 50 and older.

This study examined the application of new clinical guidelines for diagnosing frontal fibrosing alopecia in 18 men, highlighting that current diagnostic criteria may often overlook early beard involvement and sideburn recession.

This case report describes a dual transposition flap technique for closing large scalp defects post-Mohs surgery, achieving minimal alopecia and scar visibility, though it is based on a single patient.

This review examines the potential of bimatoprost for treating various types of eyelash and eyebrow hypotrichosis, discussing its pharmacological properties but providing no new clinical results.

This review discusses scalp micropigmentation techniques and their customization to individual patients, but reports no new clinical results.

This study found that intraoperative tissue expansion increased the amount of excised scalp by 20-30% during scalp reduction surgery for male pattern alopecia.

In this report, a 17-year-old boy received successful scalp reduction surgery for alopecia due to a thermal burn, achieving excellent cosmetic results without hypertrophic or keloidal scarring.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This article discusses surgical treatments for male pattern hair loss in black individuals, emphasizing the need for technique adjustments due to specific characteristics of black skin and hair, but reports no new clinical results.

Laser hair removal can be an effective last-resort treatment for men with stubborn Alopecia Areata who want to be uniformly bald.

This review explores the efficacy and safety of treatments for dissecting cellulitis of the scalp, revealing a predominance of case reports and series, and concludes that randomized controlled trials are needed for better evidence-based therapies.

This study observed that dermoscopy is a valuable tool for hair transplant surgeons to evaluate and improve the aesthetic outcomes and address technical errors in transplant procedures.

This article reviews surgical techniques for addressing scalp defects and highlights hair restoration as a cosmetic improvement strategy, but it reports no new clinical results.

Tattooing improves appearance of scalp alopecia and scars.

This study reviews the efficacy and safety of advanced therapies like TNFα inhibitors and IL-17/IL-23 inhibitors for dissecting cellulitis of the scalp, finding TNFα inhibitors particularly effective for severe or refractory cases, although prospective validation is needed for early intervention benefits.

In this guide, the authors describe a scalp incision technique that minimizes damage to hair follicles and results in barely noticeable scars in hair-bearing areas.

This study outlines a technique for hair transplantation that maintains natural hair flow and density by mimicking natural hair direction and angle without accelerating hair loss in the recipient area.
