This study found that individuals with patterned hair loss, both male and female, showed a slower linear hair growth rate compared to controls with hair of equal thickness.

This review discusses the clinical, epidemiological, and pathophysiological aspects of female pattern hair loss, reporting no new research findings.

This report describes a case of a 4-year-old boy diagnosed with linear alopecia areata, characterized by patchy hair loss and associated with unique hyperpigmented skin lesions.

This paper reviews follicular hair transplantation techniques and planning, emphasizing careful evaluation and long-term strategy for achieving excellent cosmetic results.

In this retrospective study, researchers identified a previously undetected pattern of hair regrowth resembling androgenetic alopecia in 13 of the 1604 alopecia areata cases examined.

This review discusses the pathophysiology, diagnosis, systemic associations, and treatments for female pattern hair loss and reports no new clinical findings.

In this case report, a 20-year-old woman exhibited progressive asymptomatic hair loss with a pattern inconsistent with alopecia areata or female pattern hair loss, showing areas of both extending and improving hair loss.

This review compiles recent scientific evidence and insights on female pattern hair loss for aesthetic physicians, but it reports no new clinical results.

This study found that lichen planopilaris was the most common variant of cicatricial alopecia among patients, with perifollicular fibrosis being a prevalent histopathological feature.

This case study details a 26-year-old male with depilating folliculitis, emphasizing its higher prevalence in warmer climates and showing good treatment response.

This case report discusses a rare instance of pseudolymphomatous folliculitis in a 19-year-old man, highlighting the challenge in diagnosing PLF due to its low clinical suspicion index and variable initial clinical diagnoses.

In this study, trichostasis spinulosa was observed in 51 patients with lesions on the nose, where some follicles contained up to 86 hairs each, possibly influenced by endocrine factors and actinic rays.

This study found that peripilar signs on the scalp are linked to perifollicular lymphocytic infiltrates in early androgenetic alopecia, detectable even in areas with high hair density.

This retrospective study reviewed 31 years of follicular unit transplantation data for female pattern hair loss, finding that the surgery is effective with low complication rates and avoids the need to shave recipient sites.

This study found that elevated luteinizing hormone levels were significantly associated with female pattern hair loss, and implicated LH/LHR signaling in the aging and damage of hair follicles.

This review discusses the characteristics and diagnostic challenges of fibrosing alopecia pattern distribution, proposing an algorithm for hair transplantation, but reports no new clinical results.

This study found that dermal papilla cells may play a critical role in hair follicle development and cycling by promoting epidermal proliferation and potentially mediating systemic factors that influence follicle behavior.

This study observed that male and female androgenetic alopecia share similar trichoscopic characteristics, such as hair shaft thickness heterogeneity and increased thin and vellus hairs.

This study reported that low-dose oral minoxidil combined with a 5α-reductase inhibitor improved hair density in most men with female pattern hair loss after 6 months or more of treatment.

In this study, researchers found that adults with alopecia areata exhibited trichoscopic features of empty follicular openings and tulip hair, while children showed more honeycomb pigment patterns and pohlpinkus constriction on their scalp lesions.

The researchers reported that exposure to long days after short-day treatment induced a synchronized, out-of-season wool growth cycle in New Zealand Wiltshire sheep, similar to cycles induced in other species.

This study evaluated 129 patients with androgenetic alopecia and identified an inflammatory pattern of perifollicular infiltration linked to treatment resistance. Targeting both hormonal and immune pathways improved outcomes for 67% of patients, suggesting inflammation may play a role in some cases of stubborn hair loss.

In this study, key histologic features such as mucinous perifollicular fibroplasia were identified to aid in the diagnosis of lichen planopilaris.

This study found that the occipital scalp is significantly involved in female pattern hair loss, with some patients showing clinically visible alopecia.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

This study suggests that targeting skin-infiltrated memory phenotype T cells could offer a new therapeutic approach to manage lymphopenia-related diseases like graft-versus-host disease and immune reconstitution inflammatory syndrome.

This report presents a case of alopecia areata manifesting in a linear pattern, deviating from the typical presentation of sharply demarcated round patches.
