What Is Regenera Activa?
Regenera Activa is a single-session regenerative treatment that reactivates dormant hair follicles using your own cells. Two to three tiny punch biopsies (approximately 2mm each) are taken from behind your ear, processed through the Regenera device, and injected into thinning areas. The entire procedure takes 45-60 minutes with minimal discomfort. There is no repeat session needed, no downtime, and no visible scarring at the biopsy sites.
At Dr. Top Hair Hospital, Regenera Activa is recommended for patients with dormant follicles that can still be reactivated. It works best for early to moderate thinning where follicles have slowed down but are not yet lost. Results typically become visible at 3-6 months as dormant follicles restart their growth cycle. Results last 2-3 years from a single session, significantly longer than PRP which requires sessions every 3-6 months. It can be repeated annually and combined with other treatments like PRP or ERP for a stronger overall response.

Start with a video consultation from anywhere in the world. Your hair loss pattern is evaluated to confirm dormant follicles are present and can respond to treatment.Micro-Biopsy Collection
Two to three tiny punch biopsies are taken from behind your ear or scalp under local anesthetic. Minimal discomfort, no visible scarring, and heals within days.Cell Processing
The biopsies are processed through the Regenera device to create a suspension of progenitor cells and concentrated growth factors.Scalp Injection
The regenerative solution is injected into thinning areas. The entire process takes 45-60 minutes from start to finish.Recovery
Mild soreness for 1-2 days. No repeat sessions needed. Results typically visible at 3-6 months as dormant follicles reactivate.
Every Step of Your Procedure, Explained
No Surprises
Day 1
Mild soreness at the micro-biopsy sites behind your ear. Small bandage for 24 hours. Resume normal activities immediately.
Days 2-7
Biopsy sites fully healed. Progenitor cells are beginning their work beneath the scalp surface. No visible changes yet.
Week 2-6
Cellular regeneration is underway. Dormant follicles begin receiving signals to reactivate. Hair loss stabilization is often noticed first.
Month 3-6
Early signs of improvement. Reduced shedding, finer new hairs, and improved scalp condition. Growth becomes more apparent over coming months.
Month 6-12+
Final results established. Reactivated follicles maintain their improved growth cycle. Results last 2-3 years. Can be repeated annually for extended benefit.
Frequently Asked Questions
Real questions from real patients. Straight answers from the doctors who perform your procedure.
Each treatment works differently. PRP uses growth factors from your own blood to stimulate follicles and is best for early-stage thinning. Regenera Activa uses a small tissue sample from your scalp to deliver progenitor cells directly to areas of loss. Stem cell therapy (ALMI Nanofat Transfer) harvests fat-derived stem cells, offering the most concentrated regenerative effect, and is often paired with a hair transplant. Dr. Top will recommend the right option based on your specific pattern of loss.
2-3 tiny punch biopsies (about 2mm each) are taken from behind the ear or from the back of the scalp. The area is numbed with local anesthetic. The punch sites heal quickly and are invisible within days.
Most patients describe non-surgical treatments as very comfortable. PRP and ERP involve small injections into the scalp under local anesthesia, with minimal discomfort. Regenera Activa requires a small tissue sample, also under local anesthesia, and patients report little to no pain. ALMI Nanofat Transfer involves a minor fat harvesting step, but most patients find it very manageable. RF Microneedling may cause a mild warming sensation. Overall, patient-reported pain ratings for non-surgical treatments are consistently low.
Hair shedding typically slows within weeks. Visible improvement in thickness and density at 3-6 months. Full results at 6-12 months.
It depends on your stage of hair loss. If you’re in the early stages with thinning but no significant baldness, non-surgical treatments like PRP, exosome therapy, or medication may be enough to slow progression and restore density. If hair loss is more advanced and follicles are no longer active, a transplant is likely the most effective path. Many patients benefit from both. Dr. Top will assess your situation and recommend the right approach during your consultation.
