Sebastian Penetraitt Shampoo & Conditioner Duo 33.8 fl oz Liter Bottles with Pumps — Repairing, Color-Safe for Dry Damaged Hair

Sebastian Professional Penetraitt Shampoo & Conditioner Duo is a salon-grade repair set that gently cleanses, intensely conditions, and helps strengthen dry, damaged, or color-treated hair.

This duo pairs a fortifying shampoo and a rich conditioner formulated to restore manageability and surface smoothness while preserving color vibrancy. Packaged as two 33.8 fl oz (1 L) bottles with pumps included, the set is intended for regular in-home use or backbar professionals who want long-lasting sizes. The system focuses on penetration and reinforcement of hair fibers to reduce breakage and improve detangling without weighing hair down.

How does the Penetraitt system help repair damaged hair?

The formula targets weakened areas by delivering conditioning agents and strengthening ingredients that work throughout the hair shaft. It reduces the appearance of frayed ends and improves elasticity so strands resist stretching and snapping during styling.

• Deep-penetrating conditioning to reinforce internal structure
• Detangling agents that lower mechanical breakage while combing
• Shampoo cleans without stripping essential moisture
• Conditioner smooths cuticles to restore shine and softness

Will this duo keep my color looking fresh?

Yes—the gentle cleansing action and protective conditioning help preserve color tone by minimizing surface damage and preventing premature fading. Ingredients are selected to support vibrancy rather than aggressive clarifying, making the set suitable for color-treated hair when used as directed.

• Mild surfactants that remove impurities but are not overly drying
• Cuticle-smoothing to reflect light and enhance color depth
• Conditioner adds moisture to reduce color loss from dryness
• Large 1 L bottles reduce frequent repurchase and product waste

How do I use these bottles and pumps for best results?

Dispense shampoo into wet hair, lather, and rinse; follow with conditioner focusing on mid-lengths and ends, then rinse. For stronger results, leave the conditioner on for one to three minutes before rinsing and use a wide-tooth comb to distribute evenly.

• Pumps included for controlled, mess-free dispensing
• Apply shampoo twice for heavy buildup or first-time use
• Conditioner works best on towel-dried hair for even coverage
• Use regularly to maintain improved texture and strength

Does the set protect against heat and chemical styling?

The Penetraitt duo helps minimize additional stress from heat and chemical services by improving strand resilience and smoothing the hair surface. While it supports protection, pairing with a dedicated heat protectant is recommended for frequent high-temperature styling.

• Strengthening components reduce vulnerability to styling damage
• Smoother cuticles lead to less friction and breakage
• Ideal as a preparatory system before chemical services
• Complements separate heat-protectant products for best results

Who is this for: The Sebastian Professional Penetraitt Shampoo & Conditioner Duo is designed for people with dry, weakened, chemically-treated, or color-treated hair who want salon-quality repair and ongoing maintenance in larger bottles. It suits savvy home users, busy stylists, and anyone seeking to reduce breakage, improve detangling, and keep color looking lively without daily heavy buildup. Packaging may vary, but both 33.8 fl oz (1 L) bottles come with pumps for convenient, professional dispensing.
