Clinically proven to provide conditioning protection against damage from UV rays, mechanical styling and environmental aggressors for up to 3 days, the formula helps fortify, soften, smooth and detangle the hair.

K18PEPTIDE™ helps replenish protein lost during washing, while the pH-optimised formula minimises excess cuticle swelling to help keep hair smooth and maximise shine.

Who is it best for?

K18 DAMAGE SHIELD Protective Conditioner may suit you if your hair:

• is exposed to UV rays
• is exposed to environmental aggressors
• is regularly mechanically styled
• needs protection against daily damage

What problem does it solve?

Hair can experience daily damage from UV rays, mechanical styling and environmental aggressors.

K18 DAMAGE SHIELD Protective Conditioner is designed to protect against these sources of damage while helping maintain hair health and strength.

A biotech-produced polysaccharide acts as a biomimetic shield to help protect against pollution and environmental aggressors, while a fortifying ceramide blend seals damage sites in the hair cuticle to smooth and protect against further damage.

Inside the hair, K18PEPTIDE™ helps replenish protein lost during washing.

The pH-optimised formula also minimises excess cuticle swelling during washing, helping keep hair smooth and maximise its natural shine.

Millies Expert Advice

A little goes a long way with K18 DAMAGE SHIELD Protective Conditioner. Start with a small amount from the mid-lengths to ends and build only as needed. K18 describes the formula as highly concentrated and lightweight, so you may need less than you would typically use with a traditional conditioner.

For best results, use after K18 DAMAGE SHIELD pH Protective Shampoo.

Is K18 DAMAGE SHIELD Protective Conditioner right for me?

Choose this if: you want a conditioner that softens, smooths and detangles while helping protect your hair against daily damage from UV rays, mechanical styling and environmental aggressors for up to 3 days.

Consider another product if: your primary goal is to reverse existing hair damage rather than protect against daily damage. K18 explains that its Leave-In Molecular Repair Hair Mask and DAMAGE SHIELD Protective Conditioner serve different purposes: the mask is designed to reverse damage, while the conditioner protects against daily damage.
