SUNATORIA Korean Keratin Hair Mask for Dry & Damaged Hair — 8.4 fl oz, Hydrolyzed Keratin & Argan Oil for Strength and Smoothness

SUNATORIA Korean Keratin Hair Mask is an intensive weekly treatment that rebuilds and smooths dry, damaged, or color-treated hair using dual proteins, 8 amino acids, and argan oil.

This rich, salon-style mask combines hydrolyzed keratin and silk proteins with argan oil, vitamin E, and eight amino acids to strengthen strands, reduce frizz, and add shine. Formulated for all hair types and free of sulfates, the New & Improved 2026 formula targets cuticle damage from heat, chemical processing, and environmental stress while rinsing clean and feeling lightweight.

How quickly will I notice improvement after using this mask?

Many users report softer, smoother hair after the first application, with progressive strengthening over several weekly uses. The proteins and amino acids repair and reinforce the hair fiber while argan oil restores surface smoothness and shine.

• Visible softness after one 3–5 minute treatment
• Reduced breakage and improved elasticity with regular weekly use
• Frizz control becomes more noticeable in humid conditions

Can this product work on color-treated or chemically processed hair?

Yes — the formula is built to support weakened hair regardless of processing. Hydrolyzed keratin and silk proteins penetrate the strand to rebuild structure, while the amino acids replenish lost building blocks.

• Safe for color-treated and bleached hair when used as directed
• Sulfate-free to help preserve color vibrancy
• Use weekly to maintain softness and minimize split ends

How do I use the mask for the best results without weighing hair down?

Apply to clean, towel-dried hair concentrating on mid-lengths and ends, leave for 3–5 minutes, then rinse thoroughly. For extra repair, leave up to 10 minutes or use on drier areas only; shorter application prevents buildup on fine hair.

• Shampoo first, remove excess water, then apply
• Start with a small amount for fine hair, more for thick or very dry hair
• Rinse well and style as usual; weekly use recommended

What key ingredients deliver the benefits, and why do they matter?

The mask pairs hydrolyzed keratin and hydrolyzed silk to repair and smooth the cuticle while eight amino acids restore elasticity and resilience. Argan oil and vitamin E provide surface nourishment and antioxidant support without greasy residue.

• Hydrolyzed keratin – rebuilds internal hair structure
• Hydrolyzed silk – smooths and enhances surface shine
• Argan kernel oil + Vitamin E – locks moisture and protects against dryness
• 8 amino acids (including arginine, lysine) – restore elasticity and strength

Who this is for: SUNATORIA Korean Keratin Hair Mask is ideal for people with dry, chemically treated, heat-styled, or frizz-prone hair who want a salon-level repair treatment at home. It suits straight to coily textures and works well for anyone looking to add strength, manageability, and shine to tired-looking hair without heavy residues.
