Studysummary In this study, researchers examined men with early-stage androgenetic alopecia and found distinct patterns of hair loss correlated with genetic and hormonal factors, noting that parietal region pattern hair loss responded better to minoxidil and micronutrient treatment compared to occipital region pattern.

The document "Parietal and Occipital Hair Loss Patterns in Initial Stages of Androgenic Alopecia in Men" presents multiple studies investigating early-stage male pattern baldness, focusing on hair loss in the parietal (top) and occipital (back) regions of the scalp. The studies involved a total of 547 men aged between 20 and 40 years, all diagnosed with initial stages of androgenic alopecia. The research identified two patterns of hair loss: one associated with hair density and diameter in the parietal area, and another associated with hair diameter in the occipital area. Hormonal factors, specifically increased dihydrotestosterone levels and decreased total testosterone levels, were found in patients with the parietal hair loss pattern. In contrast, patients with the occipital pattern showed a moderate increase in 17-OH-progesterone levels. The studies concluded that these two patterns of hair loss have different characteristics, pathogenesis mechanisms, and responses to conservative therapy, with the parietal pattern responding well to treatment with 5% minoxidil and personalized micronutrient correction, while the occipital pattern did not.
