Nu Skin Renu Hair Mask

Product Overview

Nu Skin Renu Hair Mask is an intensive weekly conditioning treatment designed to restore strength, softness, and smoothness to damaged or weakened hair. Positioned within the Nu Skin hair care system, it functions as a deep-repair alternative to standard conditioners, delivering active ingredients directly into the hair shaft rather than coating the surface. The mask addresses common structural concerns including brittleness, dryness, and cuticle roughness — making it suitable for hair that has experienced chemical, thermal, or mechanical damage. Ships from official Nu Skin warehouse through local NuBest stores worldwide.

Key Ingredients & Science

The formula is built around two clinically relevant actives:

• Creatine — A naturally occurring compound known for its role in cellular energy metabolism. In hair care, creatine penetrates the cortex — the inner structural layer of the hair shaft — where it binds to keratin proteins to improve tensile strength, reducing breakage under mechanical stress. Research published in the International Journal of Cosmetic Science supports creatine's ability to reinforce hair fiber integrity from within.
• CS7 — A proprietary cuticle-sealing complex developed by Nu Skin. CS7 works on the outermost layer of the hair shaft (the cuticle), smoothing raised or damaged scales to create a uniform surface. This mechanism produces lasting shine and smoothness that persists through repeated shampooing cycles, rather than washing out after a single use.

Together, these two actives address both internal structure (cortex strength via creatine) and external surface quality (cuticle smoothness via CS7), providing a dual-layer repair mechanism that distinguishes this mask from standard moisturizing conditioners.

How to Use

Use weekly in place of a standard conditioner. After shampooing, work evenly into wet hair with fingertips, paying special attention to ends and damaged areas. Leave on for 5 to 10 minutes depending on conditioning needs, then rinse thoroughly. For best results, use following Nu Skin Clarifying Shampoo as part of the complete hair care system.

Frequently Asked Questions

What is Nu Skin Renu Hair Mask?

Nu Skin Renu Hair Mask is a weekly deep-conditioning treatment formulated to hydrate and structurally reinforce damaged hair. It is designed to replace a standard conditioner in the weekly routine, delivering concentrated actives — Creatine and CS7 — to repair the hair shaft from the cortex outward to the cuticle.

What are the key active ingredients in Nu Skin Renu Hair Mask?

The two primary actives are Creatine, which penetrates the hair cortex to improve tensile strength and reduce breakage, and CS7, a proprietary Nu Skin complex that seals and smoothes the cuticle layer to deliver shine and smoothness that lasts through repeated washing.

How does Nu Skin Renu Hair Mask work?

The mask operates on two structural levels. Creatine enters the inner cortex of the hair shaft and binds to keratin proteins, increasing fiber strength. CS7 acts on the outer cuticle, smoothing raised scales to improve surface texture and light reflection. This dual-action approach repairs damage both internally and externally.

What results can I expect and in what timeframe?

When used consistently as part of the Nu Skin hair care system, users can expect visibly softer, smoother, and stronger-feeling hair. Surface improvements such as shine and reduced frizz may be noticeable after the first few applications, while structural strengthening benefits typically build with weekly use over four to six weeks.
