If you’re one of the millions of women dealing with hair thinning or hair loss, you know the search for something that works can be daunting, all-consuming even. KilgourMD, a dermatologist-founded brand that launched at the end of 2023, has become part of that conversation—and as of Tuesday, November 10, it’s gotten a glow-up.
So what’s actually new? Not the lineup. KilgourMD still offers the same four products: The Prevention Serum ($89) and The Treatment Serum ($89), which the brand launched with, and The Shampoo ($49) and The Conditioner ($49), which joined in January. Everything has sleeker new packaging, but the bigger news is inside the serums. The core actives are largely the same, including Redensyl in The Treatment Serum and the peptides and vitamin C in The Prevention Serum, but each now comes with a proprietary technology to move key botanicals deeper into the follicle.
Meet the new hero technologies, each with a suitably catchy name: GlycoRoot, in The Prevention Serum, packages basil root extract in tiny particles of plant glycogen, a natural energy source. The thinking is that building a single hair shaft takes an enormous amount of energy, so the glycogen is meant to power the follicle while ferrying the basil inside. AndroLock, in The Treatment Serum, is a peptide carrier that the brand says pulls saw palmetto, long a staple of hair-loss formulas, into the follicle, where it’s meant to help calm the effects of aging hormones. The promise for both is less shedding and visibly thicker hair by day 90.
Then there are the numbers, and they’re big. The press materials cite a 172.1 percent boost in “hair growth” and a nearly 50 percent drop in the activity of 5-alpha reductase, the enzyme that produces DHT, the hormone linked to pattern hair loss. (Worth noting: Figures like these often come from lab testing rather than from actual people, and the brand hasn’t clarified which these are, so it’s smart to keep that context in mind. The brand’s own study of 43 women found meaningful drops in shedding, but it was company-funded and had no placebo group.)
Of course, a scalp serum isn’t a replacement for minoxidil, which remains the only FDA-approved topical for regrowth. KilgourMD may make the most sense for women who can’t tolerate minoxidil, or as a complement to a routine that already includes it. The main takeaway is that there’s no miracle fix for hair loss, and no product is worth draining your bank account for. As always, check in with your dermatologist or health-care provider about what’s right for you.
After testing the new formulas, I can confirm that they work well and leave my hair feeling remarkably soft. Whether they’ll deliver on the growth promise is a longer game, so I’ll be sticking with the routine through day 90 to see what happens. In the meantime, if you’re curious, shop the line below.
