Exosome and small-molecule supply for hair and scalp protocols
ExaVeyra supplies exosome formats for topical aesthetic use to licensed practices, refers prescribers to a 503A compounding pharmacy that prepares hair and scalp formulations against an individual prescription where it holds a non-resident license, and publishes the literature and the FDA position on each formulation class so that a practice can read both before it applies for an account. This page is the door onto all of it: the blog series, the peer-reviewed science pages, the product category, and the supply pages by region and by state.
Written for licensed practitioners and practice operators: the literature, the formulation classes, and the sourcing position for each, with the regulatory notice beside every product.
Two product classes, each on its own pathway
| Product class | Ships to | Regime |
|---|---|---|
| Exosome formats for topical aesthetic use | Every state and Puerto Rico | Topical aesthetic use by licensed practitioners. Lot characterization and a certificate of analysis available on request. No exosome product is FDA-approved. |
| Compounded 503A formulations | Where the 503A pharmacy partner holds a non-resident license | Prescription products prepared for one patient. Not FDA-approved finished drug products. Listed in the hair and scalp formulations category. |

Supply by region and by state
Each regional page answers what a practice in that place can source, how cold-chain material arrives, and where the state law questions are answered. Compounded availability on every page is read from the same registry as the coverage table, so the pages cannot disagree with each other.

Program questions
- Are GHK-Cu or exosome products FDA-approved for hair loss or any form of alopecia?
- Oral one-milligram finasteride and topical minoxidil are the two FDA-approved actives in this area. The FDA has approved no exosome product of any kind, and GHK-Cu is not approved for hair loss or any form of alopecia; compounded formulations that contain them are not FDA-approved finished drug products and are prepared under section 503A against an individual prescription. The evidence pages state the regulatory position for each formulation class beside its literature.
- What does ExaVeyra supply for a hair and scalp protocol, and under which regime?
- Two product classes, each on its own pathway. Exosome material for topical aesthetic use, characterized per lot with a certificate of analysis available on request, ships to licensed practices in every state and Puerto Rico. Compounded 503A preparations, the topical solutions, creams and oral capsules listed in the hair and scalp formulations category, are prepared to an individual prescription by the 503A pharmacy partner and dispensed by that pharmacy where it holds a non-resident pharmacy license; the coverage page and the regional pages state where that is.
- Who is the program written for?
- Licensed practitioners and practice operators. The blog series is written to be read; the science pages are written to be cited, with the study design labeled beside every reference; the regional and state pages answer what a practice in a given place can source and how it arrives. None of it is written for patients, and ExaVeyra takes no part in any diagnosis, treatment decision or plan of care.
- Does ExaVeyra supply controlled substances?
- No. Testosterone and the other anabolic agents that appear in the hormonal-context article are discussed there because the literature connects them to shedding, and the article says so; ExaVeyra Sciences does not supply controlled substances.
