Hair loss in both men and women commonly manifests in the upper scalp regions, such as the temples and crown. Conversely, hair follicles located at the nape of the neck and behind the ears are genetically predisposed to maintain their resilience and health. Regenera Activa is a sophisticated supportive therapy. It operates on the principle of preparing a specialized cellular suspension from these naturally robust hair follicles. This suspension is then carefully applied to areas affected by hair loss, aiming to stimulate dormant or weakened follicles. The procedure begins with the collection of a small tissue sample, typically containing 3-4 hair follicles, from behind the ear under local anesthesia. These harvested follicles are then processed within the Regenera Activa system to yield a unique 'super cell' suspension. This personalized treatment, entirely derived from the patient's own tissue, is subsequently injected into the target areas experiencing hair thinning. A single treatment session is often sufficient. The potential need for an additional session, possibly several years later, is determined in consultation with a dermatology specialist.
