Figure 8
Photos demonstrating the division of the scalp in four halves: frontal, parietal, vertex, and occipital (a). Patients with hair loss localized to the frontal and parietal areas were injected with the AA-PRP only on the frontal areas (b); the parietal area was treated with placebo based on the injection of physiological solution. Patients with hair loss in the parietal and vertex parts were injected with the AA-PRP only in the parietal part of the scalp (c); the vertex area was treated with placebo based on the injection of physiological solution.
