Joico YouthLock Treatment Masque 5.1 fl oz — collagen-enriched deep repair for dry, frizzy hair and reduced breakage

Joico YouthLock Treatment Masque is a collagen-enriched deep-repair masque designed to soften, strengthen, reduce breakage, and boost shine for mature or damaged hair.

This intensive 5.1 fl oz treatment from Joico's YouthLock line targets dry, brittle, frizzy hair with a formulation that includes collagen and arginine to restore manageability, improve texture, and help protect against breakage. It works as a weekly or as-needed deep conditioner to detangle, add slip for easier combing, and leave hair looking smoother and more luminous without weighing strands down. Sulfate-free and focused on internal strength and surface softness, the masque pairs best with the YouthLock shampoo and conditioner for a complete regimen.

How does the YouthLock Treatment Masque improve dry, frizzy hair?

The masque replenishes moisture and fills gaps in the hair fiber to reduce roughness and flyaways, producing a noticeably softer feel. Its blend of collagen and amino-acid support helps hair appear more supple and responsive to styling.

• Collagen-rich formula smooths the cuticle for reduced frizz
• Adds slip to make detangling gentler and faster
• Leaves hair feeling nourished without heaviness

Will this product actually reduce breakage and strengthen hair?

When used regularly and paired with YouthLock Conditioner, the masque helps fortify weakened strands by delivering building-block ingredients like arginine that support surface resilience. It improves hair’s resistance during brushing and styling, which can lower breakage from mechanical stress.

• Arginine supports fiber integrity and surface strength
• Targets breakage caused by brushing on damaged hair
• Recommended use with the YouthLock Conditioner for best results

How should I use the masque for maximum benefit?

Apply to clean, towel-dried hair, working from mid-lengths to ends; leave on for the time recommended on the bottle for a deep treatment effect, then rinse thoroughly. Use once or twice weekly, or as needed when hair feels dry or frizzy.

• Use after shampooing with a sulfate-free cleanser
• Distribute evenly, focus on damaged ends and porous areas
• Rinse fully and follow with YouthLock Conditioner for a full routine

What visible changes should I expect and how quickly?

Many users notice improved softness and easier detangling after the first application, with cumulative benefits in strength and shine over several uses. Consistent incorporation into a weekly haircare routine yields the best long-term appearance improvements.

• Immediate: smoother texture and easier combing
• Short term: enhanced shine and reduced frizz after a few treatments
• Ongoing: improved hair resilience and reduced breakage when used as directed

Who is this for: Joico YouthLock Treatment Masque is formulated for mature, fragile, chemically-treated, heat-stressed, or naturally dry hair that needs targeted nourishment, softness, and strength. It’s ideal for anyone looking to restore manageability and shine without heavy buildup—especially those who pair it with the YouthLock shampoo and conditioner to address breakage and surface damage.
