Regenera Activa Designed to Restart Your Natural Hair Growth Cycle
Most countries restrict stem cell treatments. Thailand does not. Patients travel to Bangkok for SVF therapy, a regenerative treatment that uses stem cells from your own fat tissue to rejuvenate dormant follicles. Your own cells. No foreign substances. No rejection risk.
Procedure Time: 2-3 hours
Recovery Period: 24-48 hours
Full Results: 3-4 months, optimal at 6-12 months
Success Rate: 95%


What Is Stem Cell Therapy for Hair?
Stem cell hair therapy (SVF) uses your body’s own regenerative cells to stimulate hair growth. A small amount of fat is collected through minor liposuction under local anesthesia. This fat is processed to extract concentrated stem cells and growth factors, which are then injected into thinning areas of your scalp. The entire process takes approximately 2-3 hours. Because it uses your own cells, there is no risk of rejection or allergic reaction.
At Dr. Top Hair Hospital, this treatment is delivered through ALMI Nanofat Transfer, which is also Pillar 3 of Dr. Top’s Protocol. Adipose-derived stem cells are delivered directly to the scalp, promoting follicle regeneration, improving blood supply, and increasing graft circumference by approximately 33% at 12 months. This treatment is not available in Australia, New Zealand, Singapore, Hong Kong, Canada, or the UK due to stem cell regulations. It can be repeated annually and combined with transplants or other treatments for stronger results.

How Stem Cell Therapy Works: Step by Step
What to Expect
Every Step of Your Procedure, Explained
No Surprises
Day 1-2
Mild soreness at both the liposuction and scalp injection sites. Most discomfort resolves within 48-72 hours. Light activities are fine.
Week 1-2
Both treatment areas fully healed. Your body is processing the concentrated stem cells and growth factors. No visible changes yet.
Month 1-3
Stem cells are actively working to regenerate follicles and improve blood supply. Cellular repair is happening beneath the surface. Early signs of reduced shedding may appear.
Month 3-6
Noticeable improvement in hair density and thickness. Hair may appear stronger and more resilient. Most patients see meaningful results at this stage.
Month 6-12
Optimal results emerge. Hair grows stronger and fuller. Approximately 33% increase in graft circumference at 12 months. Can be repeated annually for continued 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.
Results can be long-lasting but are not considered permanent in the way transplantation is. Maintenance treatments may be recommended every 12-18 months to sustain benefits.
FUE-based techniques (FUE, FUI, DHI) extract individual follicles through tiny circular incisions less than 1mm in diameter. These heal as nearly invisible dot marks in the donor area, easily concealed even with short hair. There is no linear scar like older strip (FUT) methods. At the recipient area, the implantation sites heal without noticeable scarring. Dr. Top’s team uses precise instruments and careful technique to minimize any visible marks. Our complication rate is approximately 2% or less.
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.
The fat harvest is done under local anesthetic, and most patients describe it as comfortable. A small amount of fat is taken from the inner thigh or abdomen through a tiny incision using gentle liposuction. The whole ALMI process – harvest, processing, and scalp injection – takes about 60 – 90 minutes.
