A controlled multinational study presented at EADV 2026 found nail detachment reported by 39% of GLP-1 users versus 9% of never-users, with weight loss failing to fully explain the gap. The researchers stress the design shows association, not cause.
A review in the Journal of Obesity & Metabolic Syndrome reports that bariatric surgery still produces greater and more durable weight loss than GLP-1 receptor agonists alone, while reaching fewer than 1% of eligible patients. The authors propose treating the drugs and surgery as complementary parts of one chronic care pathway.
Khloe Kardashian has praised Omi Women's Hair Growth Peptides on the record, calling the supplement the best thing that has happened to her hair. The formula's headline ingredient is a patented keratin-derived peptide complex, and every claim about it currently comes from the brand rather than a published trial.
An NYU Langone genetic analysis reports an additional 7 percent hair loss risk linked to GLP-1 receptor activity in men with inherited male-pattern baldness. The study used genetic databases rather than patients on the drugs, and could only examine the question in men.
A paid advertorial on Newswire examines NEOLISE Renewal, a compounded four-peptide injectable protocol priced at $897 to $2,868 per term. It reports no FDA approval for GHK-Cu, BPC-157, TB-500 or KPV as used in the formulation, and unpublished identities for the prescribing group and pharmacy.
Dermatologists quoted in an Allure roundup say peptide scalp serums may reduce shedding and make hair look fuller, but are not a substitute for minoxidil or finasteride. No trial data appears anywhere in the piece, despite a fivefold price spread across broadly similar formulas.
A Vogue explainer quotes two board-certified dermatologists saying hydrolyzed collagen peptides may modestly improve skin hydration and elasticity, with results typically measured after 8 to 12 weeks. Both say supplements are an adjunct to sunscreen and retinoids, not a replacement.
A randomized placebo-controlled trial reports improvements in hair gloss and elasticity after 24 weeks of low-molecular-weight collagen peptide GT, while a separate food-science paper tests fish skin collagen peptides as a cryoprotectant in frozen gluten. The two lines of research measure very different things, and neither supports a conclusion drawn from the other.
