Alterna Professional Color Hold Color Additive Treatment, 5.1 oz – Salon Professional

Alterna Professional Color Hold is a salon-professional color additive, not a styling spray. Mix it into any professional permanent or demi-permanent hair color to turn it into an enzyme-based Alterna color service.

Why colorists use it

• More intense, more vibrant color
• Longer-lasting color through more washes
• Better gray coverage
• Enzymes help color penetrate deeper into the hair shaft and lock in

Alterna reports clinical testing showing over 10x better color intensity and over 10x better gray coverage after 28 days, compared with color alone.
