SALERM Multi-Protein Fortifying Shampoo — Hydrolyzed Keratin for Chemically Treated Hair, 42.3 oz Concentrated

SALERM Hairlab Multi-Protein Shampoo is a salon-grade, fortifying cleanser formulated with low-molecular hydrolyzed keratin and collagen-boosting agents to rebuild weakened, chemically treated hair.

This concentrated 42.3-ounce bottle delivers a single-step cleansing and strengthening treatment designed to reinforce hair fiber, improve elasticity, and impart a healthy sheen. Paraben-free and crafted for professionals and at-home users alike, the formula targets strands compromised by coloring, heat styling, or chemical processes without weighing hair down.

How does this shampoo repair and strengthen damaged hair?

The formula uses hydrolyzed keratin — smaller protein fragments that can penetrate and fill gaps in the hair shaft — alongside collagen-supporting ingredients that help restore flexibility. Together they create a protective, smoothing layer that reduces friction and visible damage.

• Low-molecular hydrolyzed keratin penetrates deeper into the fiber.
• Collagen boosters help rebuild elasticity and resilience.
• Keratin-filling action smooths cuticle irregularities for shine.
• Concentrated formula provides measurable repair with regular use.

Will this work for my chemically treated or color-treated hair?

Yes — the shampoo is formulated to support hair already weakened by coloring, straightening, or perming. It cleanses gently while reinforcing fragile areas so treatments last longer and hair feels less brittle.

• Safe for use after coloring and chemical services.
• Helps reduce breakage and split ends associated with processing.
• Enhances manageability and shine post-treatment.

How should I use the 42.3 oz bottle for best results?

Dispense a small, coin-sized amount for short hair or more for longer lengths, lather on damp hair, massage from scalp to ends, then rinse thoroughly. For more intensive repair, follow with a compatible conditioner or mask from the SALERM Hairlab line.

• Apply to wet hair, massage for 30–60 seconds, then rinse.
• Use 2–3 times weekly for repair, more often for daily maintenance.
• Pair with SALERM conditioners or treatments for deeper restoration.

Is this product free from harsh preservatives and suitable for salon use?

Formulated without parabens, the shampoo meets professional standards for concentrated performance and economy in a large 42.3-ounce format. It’s designed to withstand repeated salon use while delivering consistent repair benefits to clients.

• Paraben-free formulation for modern salon standards.
• Large professional-size container reduces refill frequency.
• Concentrated texture means less product per wash and better value.

Who is this for: SALERM Hairlab Multi-Protein Shampoo is ideal for stylists and individuals seeking a reliable, high-capacity repair shampoo for weakened or chemically treated hair. If your hair shows signs of processing damage, loss of elasticity, or dullness, this fortifying cleanser provides targeted protein support without heavy residues—recommended for those wanting salon-grade restoration at home or in professional settings.
