Glossary Serum

clear fluid remaining after blood clots, minus cells and proteins

Serum is the clear, yellowish fluid that remains after blood has clotted and the blood cells and clotting proteins have been removed. It contains important components like electrolytes, antibodies, hormones, and proteins, which are crucial for various bodily functions and diagnostic tests. In the context of hair and alopecia, serum can refer to specialized topical treatments designed to nourish the scalp and promote hair growth.

learn Hyaluronic Acid

What’s the difference between using hyaluronic acid as a serum on the scalp versus taking it as a supplement? A serum sits on the scalp surface. Oral hyaluronic acid has small trials on facial wrinkles, none on the scalp or hair.

learn Baicapil

Could a daily serum with Baicapil help revive dormant hair follicles before it’s too late? There is no independent evidence that Baicapil revives dormant follicles; the only human data are the supplier's own unpublished test. A dermatologist can tell whether follicles are still active and which treatments have evidence.

learn Bimatoprost

Can a lash-growth serum like bimatoprost actually work for your scalp? Bimatoprost (Latisse) is FDA-approved only for eyelashes, not the scalp. In the larger of two Allergan phase 2 scalp trials, every bimatoprost formulation gave smaller hair-count gains than minoxidil 5%; the results were posted to ClinicalTrials.gov but never published in a journal, and scalp use remains off-label and experimental.

learn Exosomes

Are exosomes applied as a serum, an injection, or combined with other hair treatments? Clinics offer exosomes as scalp injections, as serums applied after microneedling, or combined with PRP. No exosome product is FDA-approved, and no reliable evidence shows that any of these methods works.

learn Omega 3

Can topical omega-3 oils or serums nourish the scalp, and is taking omega-3 by mouth any better? There is little evidence that omega-3 helps hair, whether taken by mouth or applied to the scalp.
