Quick answer
In androgenetic alopecia, hair follicles shrink and produce thinner hair. In a double-blind trial with 38 patients, a stem cell extract increased hair count by 28.1% at 16 weeks versus 7.1% with control, and a 2024 meta-analysis linked stem cell-derived products to greater hair density and thickness. At Longevity Clinic, the doctor reviews your scalp photos before you travel and designs a protocol with Wharton's jelly stem cells and growth factors; each application takes about 45 minutes.
Hair loss has many causes, and not all are treated the same way. The first step is understanding why your hair is thinning and at what stage.
What happens in the follicle, at the cellular level
At the base of each follicle, the dermal papilla controls how long hair grows. In androgenetic alopecia that growth phase shortens and the follicle miniaturizes, producing thinner hairs. Signals released by mesenchymal stem cells and growth factors activate pathways that, in the lab, keep the follicle in its growth phase.
What the trials show
- In a double-blind trial with 38 patients, a stem cell extract increased hair count by 28.1% versus 7.1% with control.
- A 2024 meta-analysis linked stem cell-derived products to greater hair density and thickness.

Our protocol
Wharton's jelly mesenchymal stem cells and growth factors from stem cell conditioned medium, applied in the scalp. Longevity Clinic does not use PRP.
How it works if you live in the U.S.
- Send scalp photos and any recent lab work.
- Free review and protocol. The doctor checks for other causes (thyroid, iron, medications) that need a different treatment.
- Travel for each session, about 45 minutes each, scheduled in advance.
- Remote follow-up with control photos; hair changes take months.

A randomized, double-blind, vehicle-controlled clinical study of hair regeneration using adipose-derived stem cell constituent extract in androgenetic alopecia
Reported result: At 16 weeks, hair count increased 28.1% with the stem cell extract versus 7.1% with control; hair diameter increased 14.2% versus 6.3%.

Stem cell-derived conditioned medium for alopecia: A systematic review and meta-analysis
Reported result: Stem cell conditioned medium was associated with greater hair density (mean difference 14.93) and thickness (18.67 μm); in the 3 randomized trials alone, density still improved (mean difference 9.23).
Frequently asked questions
How many trips will I need?
Hair protocols may include more than one session spaced weeks apart. We tell you from the start how many applications your plan includes so you can schedule each trip; follow-up between sessions is remote.
Does it replace minoxidil or finasteride?
Not necessarily. Regenerative treatment is often used as a complement to first-line treatments prescribed by your doctor. Don't stop a medication without talking to your physician.
What should I send?
Clear photos of your crown, temples and hairline in good light, how long you've noticed thinning and, if available, recent thyroid, iron or vitamin D tests.
