Common questions
What's the actual difference between Empowering and ZerØ?
Empowering Keratin Treatment uses a low-dose formaldehyde formula for maximum straightening strength. ZerØ Keratin Treatment uses an amino-acid smoothing technology with no formaldehyde at all. Both target frizz and smoothing — the choice comes down to formula preference and how much straightening strength you need.
Is the formaldehyde-free formula as effective?
ZerØ is designed for smoothing, frizz control, and hydration with no formaldehyde and no reported irritation. The Empowering formula is positioned specifically for maximum-strength straightening — if straightening power is your top priority, that's the stronger option; if avoiding formaldehyde entirely is non-negotiable, ZerØ is the formula to choose.
What's the difference between buying the treatment alone vs. a kit?
The standalone treatments (Empowering or ZerØ Keratin Treatment) are just the core formula. The kits bundle in the prep and finishing steps — a Clarifying Shampoo to open the cuticle before treatment, and for the ZerØ kits, a Nutritive Hair Mask to seal it in afterward. Kits give you the complete routine in one purchase.
Should I start with a trial size or go straight to full size?
If this is your first keratin treatment from DAMANCI, the Discovery Kit (ZerØ) or Keratin Express Kit (Empowering) let you test results and fit at a lower price point before committing to the full-size Revival or Recovery kits.
