K18 Damage Shield pH Shampoo 250ml - Protective pH Balanced Shampoo

K18 Damage Shield pH Shampoo is a pH-balanced shampoo that protects hair during washing. It is suitable for those seeking a gentle daily cleanser that maintains the hair's natural balance.

What is K18 Damage Shield pH Shampoo

Shampoo formulated with an optimal pH that respects the natural acid balance of the hair and scalp. The patented K18PEPTIDE™ technology creates a protective shield that prevents protein loss during washing. The certified microbiome-friendly formula preserves the scalp's ecosystem without altering its natural bacterial flora.

Who is it for

Suitable for those who wash their hair frequently and are looking for a gentle product. It works on all hair types, especially chemically treated, colored, or sensitized hair. Ideal for those who want to maintain the results of K18 repair treatments over time.

Key Benefits

Protection during washing: The patented peptide forms a barrier that reduces keratin loss caused by water and surfactants.

pH balanced: Maintains the natural pH of the hair between 4.5 and 5.5, sealing the cuticles and reducing frizz.

Microbiome respect: Certified formula that does not alter the bacterial balance of the scalp, reducing irritation and sensitivity.

Preserved hydration: Does not strip natural oils, keeping hair soft without weighing it down.

Technology and ingredients

The formula contains 17 skincare-derived ingredients, selected for effectiveness and tolerability. K18PEPTIDE™ is a biomimetic sequence of 18 amino acids that penetrates the hair's cortex. Gentle coconut-derived surfactants cleanse without aggression. Dermatologically tested, vegan, and cruelty-free. Free from harsh sulfates, heavy silicones, and parabens.

How to use

Apply to wet hair. Gently massage the scalp for 30-60 seconds. Rinse thoroughly. For very dirty hair or hair with product buildup, first use K18 Peptide Prep Detox Shampoo. Follow with conditioner or treatment. Can be used daily.

Expected result

Hair is clean but not dry, with sealed cuticles and enhanced shine. The protein structure remains intact wash after wash. The scalp feels balanced, without itching or flaking. With continuous use, hair maintains elasticity and resistance to breakage. Compatible with K18 oil-based treatments for a complete system.
