About Maitiú

Maitiú founded The Hair Roundup to apply an evidence-led method to hair-care recommendations: every pick is built by cross-checking aggregated Amazon review data against published dermatology and cosmetic-science literature, then pressure-tested against real-world discussion sourced from Reddit and hair-care forums. The aim is honest, source-backed guidance rather than hands-on lab testing. Limitations are stated plainly, and efficacy claims are kept narrower than the evidence.
