Color treated hair Hayashi System 911 shampoo is designed for people who want to protect their hair color while repairing dryness, breakage, and chemical damage. Coloring, bleaching, and chemical treatments can weaken hair over time, making it dull, fragile, and difficult to manage. Choosing the right shampoo is one of the most important steps in maintaining healthy, vibrant hair.
This in-depth guide explains what Hayashi System 911 Shampoo is, how it works, its ingredients, benefits, and why it is especially effective for color treated and damaged hair. You will also learn how to use it correctly and whether it is the right option for your hair type.
What Is Hayashi System 911 Shampoo?
Hayashi System 911 Shampoo is a professional-grade, sulfate-free shampoo created to support damaged, over-processed, and color treated hair. It is often referred to as an emergency repair shampoo because it helps restore hair that has been weakened by chemical services such as coloring, bleaching, perming, or excessive heat styling.
Unlike many standard shampoos, this formula focuses on gentle cleansing combined with deep nourishment. Instead of stripping the hair, it works to strengthen strands, improve elasticity, and enhance overall hair health.
Hayashi System 911 Shampoo is available in multiple sizes, including 10.1oz (300ml) and 33.8oz (1000ml), making it suitable for both home use and professional salons.
Why Color Treated Hair Needs Special Care
Color treated hair is more vulnerable than natural hair. The coloring process opens the hair cuticle, allowing dye to penetrate. While this creates beautiful color, it also makes hair more prone to:
- Moisture loss
- Color fading
- Breakage and split ends
- Dry, rough texture
- Reduced shine
Regular shampoos often contain sulfates that aggressively cleanse the hair. These sulfates can wash away color molecules and natural oils, leaving hair dull and dry. That is why a sulfate-free shampoo for color treated hair is essential.
Hayashi System 911 Shampoo addresses these issues by providing gentle cleansing while preserving color and strengthening damaged hair fibers.
Key Ingredients and Their Benefits
The strength of Hayashi System 911 Shampoo lies in its carefully selected ingredients. Each ingredient plays a specific role in repairing and protecting hair.
Pro-vitamin B-5
Pro-vitamin B-5 is widely known for its moisturizing and strengthening properties. It helps hair retain moisture, improves flexibility, and enhances shine. For color treated hair, this ingredient supports smoother texture and reduces brittleness.
Panthenol
Panthenol penetrates deep into the hair shaft, helping to lock in hydration. It improves hair elasticity, making strands less likely to snap or split. This is particularly important for hair that has been chemically processed.
Hydrolyzed Proteins (Soy and Wheat)
Hydrolyzed proteins reinforce weak areas in the hair shaft. They help rebuild damaged strands and improve manageability. For over-processed or heat-damaged hair, these proteins provide structural support.
Ginseng Root Extract
Ginseng root extract nourishes the scalp and supports healthier hair growth. It also helps revitalize tired, stressed hair, making it feel stronger and more resilient over time.
Benefits of Hayashi System 911 Shampoo for Color Treated Hair
Using the right shampoo can significantly extend the life of your hair color. Hayashi System 911 Shampoo offers several important benefits:
1. Protects Hair Color
The sulfate-free formula helps prevent color molecules from being washed away too quickly. This means your hair color stays vibrant for longer between salon visits.
2. Restores Moisture
Color treated hair often becomes dry due to chemical processing. This shampoo replenishes lost moisture, helping hair feel softer and smoother after each wash.
3. Improves Shine and Smoothness
By sealing the hair cuticle, Hayashi System 911 Shampoo enhances shine and reduces frizz. Hair looks healthier and more polished.
4. Strengthens Weak Hair
Hydrolyzed proteins help strengthen fragile strands, reducing breakage and improving overall hair resilience.

- Bleaching
- Perming
- Straightening treatments
- Heat styling
Key benefits include:
- Gentle cleansing without dryness
- Improved elasticity and flexibility
- Reduced split ends and breakage
- Easier detangling and styling
With consistent use, hair feels more manageable and healthier overall.
Is Hayashi System 911 Shampoo Sulfate-Free?
Yes. Hayashi System 911 Shampoo is sulfate-free, which makes it an excellent choice for sensitive scalps and chemically treated hair. Sulfate-free shampoos are known for being gentler and less drying, especially for color treated hair.
This makes the shampoo suitable for people who want to cleanse their hair without sacrificing moisture or color longevity.
