Keratin smoothing treatments have become one of the most requested — and controversial — salon services globally[1]. Many formulations contain formaldehyde or formaldehyde-releasing substances (methylene glycol) at levels that can exceed occupational exposure limits during heat activation. The EU limits formaldehyde in cosmetics to 0.2% (as preservative); OSHA sets a permissible exposure limit of 0.75 ppm TWA[2].
2. The minimum you must do

4. Dialogue
🦉 & 🐥 & 🐮 — Salon operator dialogue
🐥
Piyo: Poppo, where does keratin treatment actually start in a real salon?
🦉
Poppo: It starts with reading the authority guidance once and writing one decision. WHO sets the international baseline; your national regulator binds you to a specific method.
🐥
Piyo: What if the staff resist the new protocol?
🦉
Poppo: Show them the failure mode it prevents and the time it saves. Authority handbooks describe the minimum viable system — you adapt, you don't reinvent.
🐮
Mou: Strong, kind, beautiful — keratin treatment made blissful for everyone in the salon.
