Keratin Republic Hair Smoothing Kit | Shampoo, Conditioner, Hair Mask & Smoothing Creme for Frizzy, Dry or Color Treated Hair

You just spent $200–$400 on a salon keratin treatment or color. Now protect it. Keratin Republic's Smooth & Hydrate 4-Step System was designed specifically for color-treated, keratin-processed hair giving you the same professional-grade ingredients your stylist uses, in your own shower. Step 1 — Hydrating Shampoo (10.1 oz) Sulfate-free, color-safe cleansing that lifts buildup without stripping your keratin treatment. Your blowout lasts longer starting in the shower. Step 2 — Hydrating Conditioner (10.1 oz) Keratin + Collagen formula floods each strand with moisture, seals the cuticle, and detangles without weighing hair down. Color stays vibrant. Frizz stays gone. Step 3 — Hydrating Mask (8 oz) Use weekly as a deep treatment to replenish protein bonds between salon visits. The difference between a keratin treatment that lasts 8 weeks and one that lasts 5 months is how you maintain it at home. Step 4 — Daily Smoothing Creme (6.7 oz) Apply to wet hair before blowdrying or flat ironing. Heat-activated keratin and collagen create a frizz-free barrier that protects your style and your treatment through humidity, rain, and everything in between. The result: Salon-smooth, color-protected hair every single day — not just the week after your appointment. Sulfate-free. Paraben-free. Vegan. Safe for all keratin treatments. Formulated for color-treated, chemically processed, dry, frizzy, and humidity-prone hair.

• EXTEND YOUR SALON KERATIN TREATMENT AT HOME — Most keratin treatments fade fast because of what you use in the shower. This sulfate-free, paraben-free 4-step system was formulated specifically for keratin and color-treated hair so your $200-400 salon investment lasts months longer between appointments.
• COMPLETE 4-STEP DAILY SYSTEM — Everything your keratin-treated hair needs in one set. Hydrating Shampoo gently cleanses without stripping. Conditioner seals and detangles. Weekly Hydrating Mask replenishes protein bonds. Daily Smoothing Creme preps wet hair for blowdrying and flat ironing with frizz-free, heat-protected results.
• FRIZZ CONTROL THAT ACTUALLY LASTS — Keratin + Collagen technology works at every step to smooth the cuticle, block humidity, and keep hair straight and sleek through rain, heat, and everything in between. For all hair types including thick, coarse, curly, frizzy, or humidity-prone hair types that need more than a regular shampoo can deliver.
• COLOR SAFE AT EVERY STEP — Sulfate-free formula cleanses without stripping color or breaking down your treatment. Your salon color stays more vibrant, your keratin stays smoother, and your hair stays healthier wash after wash. Safe for all color-treated and chemically processed hair.
• Compatible with all professional smoothing and keratin treatment systems
