DAMANCI ZerØ Keratin Treatment is a professional, formaldehyde-free keratin smoothing service for stylists who need predictable frizz control, cuticle refinement, and fiber support across fine/colored to coarse and resistant hair.

Built on an acidic pH smoothing system with glycolic and acetic acids to compact the cuticle, it pairs keratin and hydrolyzed proteins to reinforce the hair fiber and improve elasticity, while advanced silicones and cationic conditioners boost slip, softness, and high-gloss manageability. The result is immediate client-visible smoothness, reduced frizz, shine, and a more supple feel after the first service.

Add ZerØ Keratin to your smoothing menu to deliver formaldehyde-free, glossy control with a streamlined, pro-tested workflow.

Pro tips for using this product
