Is No. 6 Bond Smoother safe for sensitive scalps or those prone to allergies?

The treatment is generally well-tolerated, but because it includes fragrance and certain silicones, people with very sensitive skin or fragrance allergies should perform a patch test before full application.

What does Bis-Aminopropyl Diglycol Dimaleate do in No. 6 Bond Smoother?

This patented ingredient penetrates the hair shaft and reconnects broken disulfide bonds, restoring structural integrity, reducing breakage, and improving the hair's overall resilience and shine.

How often should No. 6 Bond Smoother be used and can it be layered with other hair products?

Apply a small amount to damp, towel-dried hair after shampooing, 2-3 times per week or as needed; it works well with color treatments, heat protectants, and styling products, though excessive layering with heavy silicones may diminish the smoothing effect.

Product Insights

Olaplex No. 6 Bond Smoother is a 100 mL leave-in treatment formulated to repair broken hair bonds, enhance smoothness, and add shine to color-treated or damaged hair. Its patented bond-building active Bis-Aminopropyl Diglycol Dimaleate works together with conditioning polymers and lightweight silicones to strengthen the cuticle and reduce frizz. The formula contains fragrance and silicone-based ingredients that may irritate very sensitive scalps, and it does not provide UV protection, so users with such concerns should patch-test before regular use.

Comparative Analysis

Positioned as a premium, salon-grade bond-repair treatment, No. 6 Bond Smoother stands out from regular conditioners by delivering Olaplex's patented bond-rebuilding technology for visibly smoother, stronger hair.
