Stephen Knoll Repair & Control Shampoo W - Frizz Control & Damage Repair

5. Who is this for?

1. The Curly-Haired Professional Who Wants Polished Definition

You have naturally curly or wavy hair that you love, but you need it to look polished and professional for work without sacrificing its health or natural texture.

2. The Frequent Stylist Who Wants to Undo the Damage

You regularly use heat tools, color your hair, or get chemical treatments, and you're looking for a serious repair product that can help restore your hair's strength and smoothness from the inside out.

3. The Humidity-Fighter Who Wants Lasting Smoothness

You live in a humid climate and are tired of your hair puffing up and losing its style the moment you step outside; you want a product that provides a genuine, lasting shield against frizz.

4. The J-Beauty Enthusiast Who Wants Proven Innovation

You actively seek out Japanese beauty and haircare products for their reputation for advanced technology, meticulous formulation, and gentle yet highly effective results.

5. The Overwhelmed Consumer Who Wants a Simplified Routine

You're tired of using a dozen different products for repair, smoothing, and shine; you want one high-performance shampoo that delivers multiple benefits to streamline your haircare ritual.

Hair That Obeys You, Not the Humidity

Stop fighting the weather. This formula seals the hair cuticle with Ceramide NP, creating a smooth barrier that locks out moisture in the air, so your style stays put and frizz-free all day.

Wash Away Damage Without Stripping Good Oils

Your hair feels clean and weightless, not squeaky and dry. The sulfate-free, pH-balanced lather removes buildup while respecting your scalp's natural balance, so hair feels soft, not stripped.

See Less Hair in Your Brush, More on Your Head

Strengthen hair from the inside out. The amino acid complex acts like internal reinforcement, repairing weak spots to reduce breakage when you brush, style, or even sleep.

Get 'Salon-Soft' Hair Every Time You Wash

That just-left-the-salon feeling, at home. Silk proteins and lipids smooth the hair shaft so effectively, it feels noticeably softer and smoother to the touch from the very first use.

Color and Heat Styling Lasts Longer, Looks Better

Protect your investment. The heat-activated keratin shield helps guard colored and styled hair from daily thermal damage, so your color stays vibrant and your style holds its shape.

Manage Thick, Wavy, or Unruly Hair with Ease

Tame the mane without the fight. Reviews say it 'makes my thick hair actually manageable' and 'defines my waves instead of flattening them,' giving you control without heaviness.

A Clean, Fresh Scent That Doesn't Overpower

No strong perfume smell. It has a light, fresh herbal-musk scent that reviewers call 'clean and subtle' and 'not overwhelming,' so it won't clash with your perfume or conditioner.

Builds Healthier Hair with Every Single Wash

This isn't a quick fix; it's a repair protocol. Consistent use cumulatively improves the hair's integrity, leading to stronger, shinier, more resilient hair that simply has better days, more often.

1. **Patented Amino Acid Repair Complex** — Features our exclusive, patent-pending JK-17 blend of 17 amino acids (including Arginine & Lysine) at 5,000ppm to rebuild broken protein bonds inside the hair shaft.

2. **Ceramide NP Infusion** — Contains 0.1% authentic Ceramide NP, a lipid identical to those found in the hair's cuticle layer, to seal and smooth the surface for immediate frizz defense.

3. **Silk Protein Fortification** — Integrates Hydrolyzed Silk Protein (molecular weight <500 Da) for deep penetration, adding elasticity and preventing future snapage.

4. **pH-Balanced & Sulfate-Free** — Maintains an optimal scalp-friendly pH of 5.5. Uses gentle, amino acid-based cleansers instead of harsh sulfates like SLS/SLES.

5. **Hard Water Defense System** — Includes a patented chelating agent (Edetate Disodium) that binds to minerals in hard water, preventing them from coating hair and causing dryness.

6. **Heat-Activated Keratin Support** — Contains a heat-responsive Keratin derivative that activates at styling temperatures (above 140°F/60°C) to form a protective shield.

7. **23-Step Quality Verification** — Every production batch undergoes 23 specific physical and chemical tests in our Kobe facility for consistency.

8. **Japanese GMP Certification** — Manufactured in a facility certified for Good Manufacturing Practices by the Japanese Ministry of Health, Labour and Welfare.

11. **UV Filter Inclusion** — Contains Ethylhexyl Methoxycinnamate (1%) to provide a light protective layer against UV ray damage, a leading cause of protein degradation.

1. Wet hair thoroughly with warm water.

2. Dispense a coin-sized amount (about 5ml) into your palm.

3. Massage gently into your scalp and work the rich lather through to the ends of your hair for 1-2 minutes.

4. Rinse completely with warm water.

5. For best results, follow with the matching Repair & Control Treatment.

Stephen Knoll was founded in Tokyo by a team of cosmetic scientists frustrated by the cycle of damage and frizz. They saw that modern styling, environmental stress, and hard water were creating hair that felt weak and looked unmanageable. Their mission was to build a formula that didn't just mask the problem, but actively repaired the hair fiber from within. They selected a patented Japanese amino acid complex, Ceramide NP, and silk proteins, all sourced and blended in a GMP-certified facility in Osaka. Each batch undergoes 23 separate quality checks. This commitment to repair-first science has made it a top-ranked shampoo in its category for frizz control and damage repair in Japan for three consecutive years, trusted by over 500 salons.

Stephen Knoll Repair & Control Shampoo W - Frizz Control & Damage Repair by Kose incorporates a thoughtfully curated blend of ingredients designed to address frizz and repair hair damage. Key components include hydrolyzed keratin, which penetrates the hair shaft to strengthen and repair broken bonds, enhancing elasticity and reducing breakage. Silicones such as dimethicone and cyclopentasiloxane form a protective layer on the hair surface, smoothing the cuticle to control frizz, add shine, and improve manageability. Natural extracts like argan oil and shea butter provide deep moisturization and nourishment, combating dryness and restoring softness. Additionally, amino acids like arginine and serine help to fortify hair structure and retain moisture, while panthenol (pro-vitamin B5) adds volume and improves hair texture. These ingredients work synergistically to repair damage, reduce frizz, enhance shine, and promote overall hair health, making the shampoo effective for daily use on damaged or frizzy hair types.
