Nioxin System 4 Leave-In Treatment offers advanced care for color-treated hair with progressed thinning, offering a refreshing finish that enhances volume and body. This professional leave-in formula helps improve the look of thickness from root to tip while maintaining a comfortable, balanced scalp environment. Designed for daily use, it adds fullness and strength to fragile strands without heaviness. With each application, hair feels revitalized, more manageable, and visibly denser, supporting a vibrant and healthy-looking finish that lasts throughout the day.

Key Ingredients:

  • Caffeine: Helps support the appearance of thicker, fuller hair while leaving the scalp feeling energized and refreshed.

  • Wild Mint Oil: Provides a cooling, invigorating sensation that helps refresh the scalp and enhance a clean, airy feel.
  • UV Protective Agents: Commonly used sun filters that help protect hair from the dulling effects of environmental exposure, maintaining vibrancy and shine.

Nioxin System 4 Leave-In Treatment combines the science of scalp care with styling performance, giving you a refreshed, fuller-looking result with every use. Its blend of revitalizing botanicals, energizing caffeine, and UV-protective agents work together to nourish and protect your hair’s natural strength and color vibrancy.

98% cotton comfort
Color: Black, Size: Large
It's true to size. I have a 42" chest and typically wear a large. I ordered large and it fits. Grab these while you can as most of these mock neck t shirts are a cotton poly blend. These are 98% cotton. This is important because although the cotton/poly blends dry quicker, they are uncomfortably warm if it gets above 70 F. I have purchased other mock turtlenecks and had my local dry cleaners convert them from long sleeves to short, but they are slightly heavier weight than these. I do wish that they made these in a dark green or military green color.

100% SYNTHETIC CONSTRUCTION!!!
Color: All White, Size: XX-Large, Color: All White, Size: XX-Large
When I bought this shirt, the listing claimed it was 95% cotton and 5% spandex... the shirt that arrived was 51% polyester, 43% viscose and 6% spandex! I have been impressed by some of their other clothing, but this is the first time I was completely lied to and bamboozled. I probably wouldn't have noticed if the shirt wasn't so hot, shiny, and uncomfortable! I will absolutely be returning this shirt. Not even CLOSE to what I wanted. Quite, quite disappointed.
