This research review explores an algorithmic approach to scalp reconstruction, emphasizing the importance of considering defect location, size, and local scalp anatomy in optimizing cosmetic and functional surgical outcomes.

The study concluded that a new method can effectively assess scalp sun damage in balding men, which increases with age and sun exposure.

This study found that isolated human scalp hair follicles express PGE2 genes and EP2 protein, suggesting PGE2 may play a crucial role in regulating hair growth.

In this study, hormonal abnormalities were detected in all investigated hirsute Saudi women, with elevated major androgens in 85.9% and polycystic ovaries in 59% of cases.

This study found that the stratum corneum of scalp skin in humans has distinct functional characteristics compared to the facial skin and volar forearm, including higher hydration levels and intermediate epidermal turnover rates.

This report reviews familial cases of aplasia cutis of the scalp, noting large irregular defects at the vertex or anterior along the sagittal suture in six families.

This article discusses using cosmetic hair products alongside medical treatments for hair conditions to enhance patient self-esteem and quality of life, without reporting new clinical results.

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

This review examines the use of dermoscopy for diagnosing common hair disorders and highlights its importance, but it does not report new clinical results.

This case report describes a flap advancement technique following skin expansion as a successful method to address primary essential cutis verticis gyrata, preserving hair growth and improving cosmetic outcomes.

Hair changes could indicate neurological diseases and help monitor treatment.

This paper reviews Behcet's disease, noting diverse manifestations with oral aphthosis most common, but reports no new results beyond existing surveys and case series.

This study reported the case of a 30-year-old man with a bluish-grey scalp nodule that developed over a previously stable hairless plaque, revealing histopathological features consistent with epithelioid cell nests and spindle-shaped dermal melanocytes embedded in collagen.

In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.
