🧠 Introduction

The global “keratin serum” market is booming, promising salon-smooth hair, heat protection, and “reconstruction” in a bottle.
Yet most formulas simply coat the hair rather than repair it — using silicones, film-formers, and synthetic polymers.
Some are harmless; others contain irritants or even trace formaldehyde, raising concerns for long-term users and professionals.

This investigation compares four best-selling products on Amazon Mexico, rating ingredient safety from 1 (risky) to 10 (safe), focusing on health impact, scalp absorption, and environmental persistence.

⚖️ Summary Table — Health & Environmental Safety

Brand / Product Key Concern Human Safety Eco Impact Overall Rating

🌿 Consumer Guidance

💧 Avoid heat-activated “keratin straighteners” that contain formaldehyde or glyoxylic acid. These chemically alter hair and release irritant fumes.

✨ Choose leave-in serums with hydrolyzed proteins, vitamins, and plant oils — preferably silicone-free or low-silicone.

🌀 Clarify once weekly to prevent buildup if using silicones.

🌬️ Ventilate or use outdoors if any product instructs blow-drying or flat-ironing after application.

👃 Fragrance-sensitive users: opt for unscented or natural oil–based formulas.

🔍 Conclusion

Most “keratin serums” are safe surface treatments, not real reconstruction therapies.
Their results are optical — a smooth cuticle reflection, not molecular repair.
For true hair health, hydration and nutrition matter more than synthetic coating.
