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 There is no independent evidence that Baicapil revives dormant follicles; the only human data are the supplier's own unpublished test.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.
