This article provides a diagnostic guide for clinicians to differentiate between various hair shaft disorders by using a structured question-by-question approach but does not report new clinical findings.

This chapter reviews patchy hair loss due to skin disease, nail disorders related to chronic trauma, and treatments for small carcinomas, but it reports no new clinical findings.

This paper reviews plica polonica, a rare hair disorder linked historically to poor hygiene and now to severe self-neglect or medical conditions, and outlines various treatment and preventive strategies but reports no new findings.

In this case report, a 62-year-old woman with suspected discoid lupus erythematosus experienced worsening skin and hair symptoms despite treatment with topical corticosteroids, immunomodulatory therapy, and hydroxychloroquine, leading to her referral to a tertiary dermatology center.

This review provides an overview of the etiology, presentation, and diagnosis of steatocystomas, including subtypes and complications, while detailing their history, epidemiology, and management strategies.

In this case report, researchers documented a 19-year-old male professional athlete with acquired trichorrhexis nodosa, noting environmental factors like chlorine exposure during swimming may have contributed to his condition, which improved after advice on hair care changes.

The study developed a hair cream using extracts from plants like Hibiscus rosa sinensis and Nigella sativa, reporting that it may protect the scalp and hair by providing antimicrobial effects, promoting hair growth, and preventing hair fall and graying.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

This genetic study identified a potential interval for the Marie Unna hypotrichosis gene but found no mutations in the nearby hr gene, suggesting its involvement remains unconfirmed.

This case report describes a man with trichorrhexis nodosa of the beard, who experienced symptomatic improvement after being advised to shave and avoid brushing, confirming the diagnosis.
