ReNu Smoothing Conditioner(1000ml) (USA)

Nu Skin ReNu Smoothing Conditioner 1000ml — Frizz-Control Conditioner for Sleek, Manageable Hair

If the smoothing shampoo begins the anti-frizz process, the smoothing conditioner finishes it. Nu Skin ReNu Smoothing Conditioner seals the cuticle smooth, locks in moisture, and provides the slip and detangling that prevents breakage during brushing. The result is hair that air-dries sleeker, takes less time to style, and holds its shape better in humidity. Paired with the Smoothing Shampoo in 1000ml professional size, this conditioner completes a frizz-management system designed for months of consistent results.

Conditioner's primary job is to neutralize the negative electrical charge that washing creates on hair fibers (which causes static and flyaways) and to smooth the cuticle layer. Smoothing conditioners go further by depositing lightweight agents that keep the cuticle flat even after drying and styling. For frizz-prone hair, this extended smoothing is the difference between hair that behaves and hair that poofs the moment you step outside.

Key Benefits

• Cuticle sealing — Locks the cuticle flat for sleeker, shinier, more manageable hair
• Frizz resistance — Helps hair resist humidity-induced frizz throughout the day
• Easy detangling — Provides slip that prevents breakage during brushing
• Moisture balance — Hydrates without weighing hair down
• Professional 1000ml size — Months of conditioning from a single bottle

Key Ingredients

The conditioner complements the smoothing shampoo with cuticle-sealing and moisture-locking technology.

• Smoothing Agents — Lightweight conditioning molecules that coat the hair fiber, laying the cuticle flat and creating a smooth surface that reflects light (shine) and repels excess humidity (frizz resistance). These agents provide the "sealed" finish that keeps hair looking sleek between washes.
• Detangling Complex — Reduces friction between hair strands, making combing and brushing easier and less damaging. For frizzy hair that tends to knot, this is essential — aggressive detangling causes breakage, and breakage creates the short, flyaway strands that contribute to the appearance of frizz.
• Hydrating Agents — Balanced moisture delivery that hydrates the hair shaft without the heaviness that weighs down limp hair. Well-hydrated hair is inherently less frizzy because it doesn't absorb moisture unevenly from the environment.
• Panthenol — Adds internal flexibility and strength to each strand, reducing the brittleness that causes breakage and split ends.

What Sets It Apart

The ReNu Smoothing Conditioner is formulated as a system partner to the Smoothing Shampoo — they use complementary technologies. The shampoo cleanses without cuticle damage; the conditioner seals the cuticle flat and adds lasting smoothness. Using both together produces better results than using either alone because the shampoo creates the smooth foundation and the conditioner locks it in.

The 1000ml format matches the shampoo, so both products run out at approximately the same time — no awkward mismatches where you've run out of conditioner but have half a bottle of shampoo left (or vice versa). It's a practical detail that matters when you're buying a matched hair care system.

How It Compares

How to Use

After shampooing with ReNu Smoothing Shampoo, squeeze excess water from hair. Apply conditioner from mid-length to ends — where frizz and damage are most concentrated. Leave on for 1-2 minutes, then rinse with cool water (this is important — cool water seals the cuticle flat, which is the entire point of a smoothing system). For extra conditioning, leave on for 3-5 minutes under a shower cap before rinsing. Use daily as part of your smoothing routine.

Best For

ReNu Smoothing Conditioner is designed for anyone with frizz-prone hair — curly, wavy, or straight hair that puffs in humidity or develops flyaways. Ideal for medium to thick hair textures and for color-treated hair. If you have very fine hair that tends to go flat, the Volumizing Conditioner is a better match — smoothing conditioners can weigh fine hair down.

Frequently Asked Questions

Q: Do I need to use the matching shampoo?

A: For best results, yes — the products are formulated as a system. If you use a sulfate-based shampoo, it will rough up the cuticle that this conditioner is trying to smooth, partially undoing its work.

Q: Can I use this on curly hair?

A: Absolutely — smoothing conditioner enhances curl definition by reducing frizz and flyaways. Your curls will look more defined and less puffy. It doesn't straighten curls — it refines them.

Q: How often should I condition?

A: Every time you shampoo. Some people with very thick or dry hair also "co-wash" (condition without shampooing) on alternate days for extra moisture. This conditioner works for both approaches.

Q: Will this build up on my hair over time?

A: The lightweight smoothing agents are designed to rinse clean each wash. However, if you notice buildup after several weeks, use a clarifying shampoo once to reset, then return to the smoothing system.

Q: How long does the 1000ml bottle last?

A: 4-6 months with daily use on medium-length hair. Thicker or longer hair may use more product per wash, bringing it to 3-4 months. The bottle is designed to last approximately the same duration as the matching shampoo.
