SALERM Multi-Protein Fortifying Shampoo 42.3 oz — Hydrolyzed Keratin & Collagen Boost for Strength and Shine

SALERM Hairlab Multi-Protein Shampoo is a concentrated fortifying cleanser formulated with low molecular weight hydrolyzed keratin and collagen boosters to strengthen, rebuild and add shine to weakened hair.

This professional-grade shampoo targets hair that has been weakened by chemical services, heat styling or daily wear. The lightweight hydrolyzed keratin penetrates the fiber while collagen-promoting ingredients help restore elasticity, so strands feel firmer and look smoother after regular use. The formula is paraben-free and designed to be a concentrated, salon-strength step in a rebuilding routine.

How does this shampoo improve the strength and elasticity of hair?

The shampoo uses hydrolyzed keratin, a smaller protein fraction that more readily adheres to damaged areas of the hair shaft. By coating and filling weakened zones, it helps reduce friction between cuticle layers and improves tensile strength. Over time, repeated use supports better elasticity and fewer breakage points.

• Low molecular weight hydrolyzed keratin for deeper fiber penetration
• Collagen-boosting ingredients to support elasticity
• Concentrated formula reduces the need for heavy applications

Will it work on chemically treated or heat-damaged hair?

Yes — the formula is specifically formulated for hair that has undergone coloring, bleaching, smoothing or frequent heat styling. It focuses on rebuilding the internal structure of the strand rather than only smoothing the surface, which helps hair better tolerate future salon services and styling stress.

• Safe for color-treated hair when used as directed
• Targets cuticle roughness and weakened mid-lengths and ends
• Helps reduce visible split ends and frizz when paired with conditioning care

How should I use it to get the best results?

Apply to wet hair, emulsify into a gentle lather from roots to ends, then rinse thoroughly. For stronger repair benefits, use twice: first to remove residue, second to let the active keratin and collagen boosters adhere to the fibers. Follow with a compatible conditioning or mask for longer-lasting softness and manageability.

• Use on damp hair; massage into scalp and lengths
• Rinse completely; repeat if hair is heavily product-laden
• Pair with a SALERM conditioner or mask for optimal repair

What results can I expect and how quickly?

Immediate effects typically include cleaner, smoother-feeling hair with improved shine. Noticeable improvements in strength and reduced breakage usually appear after several washes as the keratin rebuilds stressed areas. Consistent use as part of a repair regimen will deliver the most durable results.

• Instant: improved texture and surface smoothness
• Short-term (a few washes): enhanced shine and reduced frizz
• Ongoing: stronger strands and better elasticity with regular use

Who is this for: SALERM Hairlab Multi-Protein Shampoo is intended for people with damaged, weakened or chemically treated hair who want a salon-grade repairing cleanse. It's suitable for anyone seeking a paraben-free, protein-enriched product to reinforce hair structure and improve manageability. If your hair is very fine or protein-sensitive, consider using less frequently or alternating with a nourishing, low-protein shampoo to maintain balance.
