🚫 “냄새 없는” 함정: 머리카락이 녹는 이유!
혹시 향이 더 좋아서 “암모니아 무첨가” 염색약으로 바꿔본 적 있으세요? 그 기분 좋은 향 뒤에는 모발을 조용히 손상시키는 화학 물질이 숨어 있을지도 몰라요.
🔍 비밀 재료: 에탄올아민(MEA)
많은 브랜드들이 암모니아 특유의 자극적인 냄새가 없다는 이유로 “순한” 제품이라고 광고하지만, 실제로는 암모니아 대신 MEA를 사용하는 경우가 많습니다 .
| Feature | Ammonia (The Smelly One) | Ethanolamine/MEA (The Odorless One) |
| Scent | Pungent & strong | Odorless & pleasant |
| After-care | Evaporates quickly into the air | Sticky; clings to the hair shaft |
| Residue | Leaves very little behind | Stays in hair even after rinsing |
⚠️ The Danger Zone: Perming After Self-Dyeing
If you dye your hair at home with MEA-based products and then get a perm, you are at high risk for “Melting Hair.”
- The Reaction: The residual alkaline from the MEA reacts violently with perm solution.
- The Result: Excessive softening that turns hair mushy, brittle, or “melted”—often causing irreversible damage.
✅ How to Save Your Hair (Pro Tips)
- Check the Label: Look for “Ethanolamine” or “MEA” on your box dye.
- The 3-Day Rule: For 2–3 days after dyeing, use an acidic (low pH) shampoo. This helps neutralize the alkaline residue.
- Ditch the Heat: Avoid straighteners or curling irons immediately after dyeing. High heat accelerates the chemical reaction with residual MEA.
- Rinse Twice: If using “odorless” dye, rinse much longer than you think you need to.
💡 Summary: Just because it doesn’t smell doesn’t mean it’s safe.
