Advanced Scalp Mesotherapy for Hair Loss “Regenera Activa” is an innovative treatment for hair loss that leverages the potent regenerative properties of stem cells, growth factors, and progenitor cells. A healthy tissue sample is harvested, processed into a special suspension, and injected into the scalp. This therapy stimulates hair follicles, leading to hair growth, thickening, and reduced hair shedding within 1-3 months.
