Best Hair Formula App 2026

Best Hair Formula App in 2026: StrandNotes vs Charm, Gloss, HairTracker & More

We compared the top hair color formula apps on what actually matters behind the chair — structured formula logging, client photos, client-safe sharing, and price. Including the newest app in the category, StrandNotes.

We made StrandNotes, so we’re biased. We’ve tried to be accurate — where other apps do something better, we say so.
