Podcast episode (recorded June 20, 2025) in which host Natalie Jill interviews Carolina Reis Oliveira (co-founder, One Skin) about midlife hair thinning and One Skin’s OS-01 hair serum. They explain senescent ("zombie") cells as drivers of scalp aging and hair-cycle disruption, DHT/hormone roles, and multifactorial contributors (genetics, stress, nutrition, oxidative/sun damage). Carolina describes OS-01 (a proprietary peptide previously developed for skin), lab validation showing reduced senescent cell load and increased hair growth, formulation additions (Panax ginseng root extract, fisetin antioxidant), and a small clinical trial (n=30) with measurements at 3 and 6 months. Reported clinical outcomes at six months: 86% of participants showed an average 40% increase in hair density, 43% increase in follicle thickness, and 38% more hairs in anagen phase. Product is drug-free, intended for twice-daily topical use (can be combined with minoxidil or other treatments), generally presented as safe with no contraindications cited (speaker stated safe even in pregnancy). Host reports personal early results (visible fine fuzz ~11–12 weeks) and encourages 3–6 month commitment to assess efficacy.
