This study found that in patch- and plaque-stage scalp psoriasis, sebaceous gland atrophy and reduced hair follicle size were common but there was no evidence of alopecia.

This study found that specific junctional proteins are significantly downregulated in balding regions of the scalp in men with androgenetic alopecia, suggesting disrupted cell communication may play a role in hair loss.

Sparse hairs below frontal hairline can indicate early male balding.

In this study, trichoscopy was identified as a useful non-invasive tool to aid in the diagnosis of female pattern hair loss, with peri pilar sign and hair diameter variability being common findings.

This study suggests that congenital atrichia with papular lesions may be more common than previously thought and proposes diagnostic criteria including the observation of hypopigmented whitish streaks on the scalp.

This study found that individuals with androgenic alopecia have an increased number of thin hairs (less than 40 microns in diameter) per cm², which may affect their clinical appearance.

This review of 1360 scalp biopsy specimens revealed that 12.5% of cases involved multifactorial alopecia, highlighting the diagnostic complexity of multiple forms of alopecia present in single biopsies.
