Joico YouthLock Shampoo — 10.1 fl oz sulfate-free cleanser with collagen & arginine for softness, shine and reduced breakage

Joico YouthLock Shampoo is a sulfate-free cleanser enriched with collagen and arginine that gently removes buildup while improving softness, shine, and resilience for aging or fragile hair.

This sulfate-free formula is designed to refresh mature or weakened hair without stripping moisture. Infused with collagen and arginine, the shampoo aims to restore bounce and manageability while supporting smoother comb-through and increased surface shine. Lightweight surfactants cleanse dirt and styling residue so strands feel clean and conditioned rather than dry or brittle.

How does this shampoo protect hair from breakage?

The YouthLock blend targets mechanical breakage by improving slip and reducing friction during detangling and styling. When paired with the matching YouthLock Conditioner it helps lower hair fall due to breakage from brushing, supporting stronger-looking strands over time.

• Collagen helps improve strand flexibility and surface integrity.
• Arginine supports the hair fiber for improved resilience.
• Formulated to boost slip for easier comb-through and less tugging.
• Designed for daily use without harsh sulfates that can dry hair.

Will this work on fine, thin, or color-treated hair?

Yes — the gentle cleansing system is suitable for fine or thinning hair and won’t weigh hair down. It removes impurities while maintaining body and shine, and is compatible with color-treated hair because it avoids SLS/SLES sulfates.

• Lightweight formula preserves natural volume and movement.
• Sulfate-free cleansing helps protect color vibrancy longer.
• Boosts shine without coating or heavy silicones.

How should I use Joico YouthLock Shampoo for best results?

Apply to wet hair, work into a lather focusing on the roots and scalp, then rinse thoroughly. For optimal reduction in breakage and added softness, follow with the Joico YouthLock Conditioner and detangle gently when hair is conditioned.

• Wet hair fully before applying a quarter-sized amount or more for long hair.
• Massage scalp to lift buildup and stimulate circulation.
• Rinse well and use YouthLock Conditioner to complete the system.

What key ingredients power the YouthLock Shampoo?

The formula centers on collagen and arginine to support elasticity and strength, combined with mild cleansing agents that remove dirt without stripping natural oils. It is free from SLS/SLES sulfates for gentler daily use.

• Collagen-derived components to help improve texture and suppleness.
• Arginine for fiber support and improved strand resilience.
• Sulfate-free surfactants for effective but gentle cleansing.

Who is this for: Joico YouthLock Shampoo is ideal for anyone noticing reduced bounce, more friction during styling, or increased breakage, especially mature or fragile hair types. It's suited to those seeking a gentler daily cleanser that supports softness and shine while working best as part of the YouthLock system with its conditioner for maximum benefits.
