Our Progressive keratin straightening light blue is specially formulated for blonde, bleached, fine, or chemically treated hair. This gentle yet powerful treatment smooths, strengthens, and hydrates without compromising color or overloading fragile strands. Designed to straighten hair up to 60–70%, it helps reduce frizz, enhance manageability, and restore lost natural keratin — bringing damaged hair back to life while maintaining its natural movement and tone. Clinically developed in Colombia, this formula is safe for scalp and skin, and delivers visible results after just one use. Expect smoother, healthier, shinier hair that lasts up to 6–7 months, with a soft, lightweight finish ideal for finer textures.

Save money and create the perfect ritual for your hair: Each 1L bottle lasts for 8–10 full applications and has a 3-year shelf life — giving you lasting results and unmatched value over time.

For best results, use within 12 to 24 months after opening. Keep the bottle tightly closed, and store in a cool, dry place, away from sunlight or humidity to maintain product quality.

Tip: Our professional-size bottle is perfect for sharing! You can safely share it with family or friends—just be sure to keep the cap tightly closed between uses to avoid contamination.
