GK HAIR Keratin Shampoo 1L Salon Size — Deep Hydration, Repair & Color-Safe Frizz Control

This 33.8 oz professional bottle of GK HAIR Keratin Shampoo is formulated to restore moisture and resilience to hair that’s been weakened by heat, chemical services or environmental stress. The formula centers on keratin protein to reinforce the hair shaft while providing slip for easier detangling and shine. It’s designed to be mild enough for regular use and effective for color-treated hair, helping to maintain pigment without stripping or harsh cleansing.

How does this shampoo repair and hydrate damaged hair?

The shampoo deposits keratin and nourishing agents that temporarily fill gaps in the hair cuticle, improving texture and tensile strength after repeated use. Hydrating components restore moisture balance so strands feel softer and are less prone to breakage.

• Keratin-infused formula rebuilds weakened areas of the hair fiber
• Moisturizers smooth the cuticle to reduce roughness and tangles
• Slip-enhancing ingredients make detangling gentler and faster
• Salon-size 1L supply for frequent use and consistent results

Will this shampoo help my color-treated hair stay vibrant?

GK HAIR Keratin Shampoo is made to cleanse without aggressively stripping color, helping hues retain saturation longer between touch-ups. The gentle surfactants remove buildup while protecting dye molecules so color looks brighter and fresher after each wash.

• Sulfate-free surfactant system reduces color fade
• Formulation balances cleansing and protection for dyed hair
• Maintains shine, which enhances perceived color vibrancy
• Suitable for regular routines that include color-safe products

How does it control frizz and make hair easier to style?

By smoothing the cuticle and adding moisture, this shampoo reduces surface friction that causes flyaways and frizz. The result is more manageable hair with improved shine, so styling tools and products perform more predictably.

• Cuticle-smoothing action decreases frizz and static
• Hydration minimizes humidity-related puffiness
• Prepares hair for conditioners, serums and heat protectants
• Leaves hair flexible for both sleek and textured styles

Is this safe for sensitive scalps and everyday use?
