The short answer
- What they are: Extracellular vesicles involved in cell signaling; commercial hair products vary widely in source and processing.
- FDA: Exosomes are not FDA-approved for hair growth. MOHR states this plainly.
- At MOHR: Considered only as an adjunct in the Advanced program when clinically appropriate and legally permissible, never as a standalone miracle.
- Decision path: HairCheck or $299 assessment before any program.
What are exosomes in a hair-loss context?
Exosomes are tiny extracellular vesicles that cells use to exchange signals. In aesthetic and regenerative marketing, “exosome” products are promoted for scalp rejuvenation, but products and evidence quality are not uniform.
That variability is why clinic claims should stay modest. Source material, purification, storage, and application method all differ across vendors and practices.
What does the evidence say?
Interest is real; definitive, large, standardized clinical proof that a specific exosome product reliably restores hair density is not. Patients should be wary of before/after marketing that omits diagnosis, concurrent treatments, and follow-up length.
MOHR’s core regenerative workhorse remains autologous PRF, which uses the patient’s own blood. Exosomes, when used, are adjunctive, not a replacement for measurement or candidacy judgment.
FDA and regulatory honesty
Plain language
Exosomes are not FDA-approved for hair growth. They are offered at MOHR only where clinically appropriate and legally permissible, as decided at the in-person assessment, not from a website quiz.
How MOHR uses them
Exosome adjunctive treatment appears in the Advanced three-treatment program alongside PRF, LLLT, and the hair-growth IV, not in Essential. Your provider decides fitness during the $299 assessment at 910 Park Avenue. See pricing for current program inclusions.
If exosomes are not appropriate for you, that is a successful assessment outcome, not a failed sale.
Frequently asked questions
Are exosomes stem cells?
No. Exosomes are vesicles that can carry signaling cargo; they are not intact stem-cell transplants. Marketing that blurs those terms is a red flag.
Can I buy exosomes online and skip the clinic?
MOHR does not endorse unregulated self-experimentation. In-clinic decisions follow evaluation and local regulatory constraints.
