GK HAIR Keratin Shampoo for Dry, Damaged & Color-Treated Hair — 1L Salon Size, Sulfate-Free Hydrating Repair

GK HAIR Keratin Shampoo is a salon-grade, sulfate-free cleanser that hydrates, repairs and smooths dry or color-treated hair using keratin-enriched conditioning agents.

Formulated to restore strength and manageability, this moisturizing shampoo targets dryness, frizz and faded color while remaining gentle on sensitive scalps. The 1L (33.8 oz) salon-size bottle is designed for frequent use at home or in professional settings, delivering consistent hydration and a polished finish. It supports a full hair-care routine when paired with conditioners, leave-ins and heat protectants.

How does this shampoo repair and hydrate damaged hair?

The formula contains keratin-building ingredients that help replenish the hair surface and improve elasticity, while conditioning agents deliver lasting moisture. Regular use reduces dryness and leaves strands feeling softer and more flexible.

• Keratin-enriched mix to strengthen weakened cuticles.
• Moisture-locking emollients for long-lasting hydration.
• Gentle cleansing preserves natural oils without stripping.

Will it control frizz and make hair smoother?

Yes—this shampoo reduces frizz and flyaways by smoothing the hair cuticle and adding slip for easier detangling. The result is sleeker-looking hair that’s simpler to style and manage day to day.

• Cuticle-smoothing actives minimize surface roughness.
• Reduced static and flyaways for a polished appearance.
• Improves comb-through and styling performance.

Is it safe for color-treated hair and sensitive scalps?

The sulfate-free, gentle formula cleans without aggressively stripping dyes, helping maintain color vibrancy between salon visits. Mild surfactants and a non-irritating base make it suitable for many sensitive scalps, though patch testing is recommended for highly reactive skin.

• Formulated to preserve hair color and vibrancy.
• No harsh sulfates that commonly fade dyes.
• Suitable for routine use on most sensitive scalps.

How should I incorporate this shampoo into my routine?

Use as your primary cleansing step: wet hair thoroughly, apply a small amount, lather and rinse, repeating if needed for heavy product build-up. Follow with a GK HAIR conditioner or treatment to lock in moisture and enhance smoothness.

• Daily or alternate-day use depending on hair type and activity level.
• Pair with leave-in conditioners and heat protectants for styling.
• Ideal in professional or home-care regimens due to 1L salon size.

Who is this for: GK HAIR Keratin Shampoo is aimed at people with dry, damaged or color-treated hair who want a gentle, reparative cleanse that reduces frizz and supports smoother styling. It’s also suited to salon professionals and frequent washers who need a larger bottle for consistent results. If you prefer sulfate-free formulas and look for products that work alongside conditioners and styling treatments, this keratin-focused shampoo is a practical addition to your hair-care lineup.
