This article describes cases of unusual scalp whorl patterns, including triple parietal and right temporal whorls, that were associated with normal development, and discusses theories of hair whorl development.

This article proposes a standardized naming system for areas of the balding scalp to improve communication among hair restoration professionals, but it reports no clinical results.

This proposal presents a standardized system for naming areas of the balding scalp to improve communication among hair restoration professionals, defining major regions and introducing new landmarks.

In this study, researchers observed that men with androgenic alopecia in a Pakistani population had significantly lower hair density than those without hair loss, particularly at the frontal and parietal scalp regions.

This article reviews androgenetic alopecia in women, highlighting diagnosis criteria and noting that topical minoxidil is currently the only proven treatment for hair growth; it reports no clinical trial findings.

This case report describes androgenetic alopecia in two young siblings, highlighting its occurrence in children and suggesting a possible familial pattern given their mother's similar condition.

In this viewpoint, researchers discussed the possible role of the developmental origin of scalp dermis in influencing the specific pattern of hair follicle miniaturization seen in male pattern hair loss, noting that frontal follicles are more susceptible while occipital follicles remain largely terminal.

This article discusses how dihydrotestosterone (DHT) contributes to male pattern baldness by affecting genetically sensitive hair follicles and includes no new research findings.

In this study, a 40-year-old man with hair loss showed complete hair regrowth and no relapse 24 weeks after receiving umbilical cord mesenchymal stem cell and secretome injections, highlighting their potential for alopecia treatment, although further research involving larger populations is needed.

This study concluded that hair transplants including the parietal eminence area can enhance aesthetic balance and provide indirect cosmetic benefits, even when the vertex is left untreated due to limited donor availability.

The authors suggest that during hair transplantation for hair loss, the parietal eminence area should be prioritized along with the mid-scalp to address future noticeable thinning, especially since this area often becomes more conspicuous over time.

This case report describes a unique presentation of frontal fibrosing alopecia characterized by a hair loss pattern that resembles the Greek letter upsilon, supported by trichoscopic and histological findings.

In this study, researchers found that using a handheld digital microscope, hair diameter was a better determinant of perceived alopecia severity in androgenetic alopecia than hair density.

This study suggests that male androgenetic alopecia and female pattern hair loss follow distinct progression pathways, characterized by different trichoscopic patterns related to hair diameter and follicular unit changes.

This study observed that progressive frontal recession in postmenopausal women may exhibit features of fibrosing alopecia, suggesting a distinct reaction pattern from typical lichen planopilaris.

In this study, lupus panniculitis of the scalp was associated with a high incidence of recurrence and progression to systemic lupus erythematosus, despite various treatments showing complete response within weeks.

This study suggests that surgical intervention for scalp infantile hemangiomas, often necessary due to complications like alopecia and ulceration, generally leads to good aesthetic outcomes and satisfactory hair growth.

In this study, researchers characterized alopecia areata incognita in men, finding that all 29 male patients had concurrent androgenetic alopecia, and treatment with ultra-potent topical corticosteroids and minoxidil led to remission in 4-8 months.

This study developed a method to measure local steroid hormone concentrations in hair, providing new insights into hormone dynamics associated with androgenetic alopecia.

This review discusses the pathophysiology, diagnosis, and treatment of polycystic ovary syndrome, emphasizing the critical importance of early diagnosis and treatment to prevent metabolic complications and improve quality of life.

This report describes a case of isolated congenital atrichia combined with nevus flammeus.

This study found that women with androgenetic alopecia demonstrated higher androgen receptor gene expression compared to controls, with a correlation found between higher AR expression and fewer CAG repeats in the AR gene.

This study found significant differences in hair density, non-vellus hair diameter, and percentage of miniaturized hair between normal women and those with female pattern hair loss, particularly in the midscalp and parietal areas.

This article reviews the complex challenges of managing scalp and cranial deformities post-trauma or surgery, advocating for better multidisciplinary approaches to enhance outcomes, but reports no new results.

This study found that scalp medical tattooing effectively improved cosmetic appearance and concealed bifid parietal whorls without complications in the patients evaluated.

This study observed an alopecia syphilitica-like pattern of hair loss in a woman with frontal fibrosing alopecia, suggesting it may be another atypical presentation of the condition.

This study observed that frontal fibrosing alopecia is increasingly diagnosed in Italian Caucasian females, often showing premenopausal onset and eyebrow alopecia as an early sign.

This review discusses the classification and diagnosis of primary scalp alopecia, focusing on scarring and non-scarring types, and reports no new clinical results; it emphasizes simplified diagnostic pathways and tissue processing techniques.

This case report describes an atypical presentation of alopecia areata in a 53-year-old postmenopausal woman, which may resemble frontal fibrosing alopecia and complicate diagnosis.

Balding men have harder scalps.
