  intro: "Wash cadence is one of the most personal decisions in a hair routine — and one of the most misunderstood. There is no universal answer to 'how often should I wash my hair?' What exists instead are three distinct frameworks: the full wash day (shampoo, condition, style), the off-day refresh, and the co-wash as a mid-week maintenance option. Below is everything we've published across all three — the beginner's path, what's trending, a cadence decision table, and the full how-to library.",

It isn't about cleanliness — it's about scalp health, strand integrity, and not disturbing whatever curl or wave pattern you're working with. Get the cadence wrong and you're either stripping your hair of its natural oils every 24 hours, or waiting so long that build-up disrupts the scalp. The goal is a rhythm your hair can rely on.",
