SHAKE WELL. Non-aerosol format may feel slightly damp but will not disturb your style.

1. Hold the bottle 4-6 inches away from scalp for even distribution
2. Section hair and apply just 1 spray per section. Less is more. Add only as needed
3. Massage in and brush or style as usual

If the hair feels gritty or powdery, you may have applied too much product. Brush hair to distribute the product, or reset hair with an in-shower shampoo.

Check out our team’s K18 mask doses across all different hair types, lengths + levels of damage.

Once you’ve got your dose perfected be sure to follow these tips for your best #k18results

CLARIFY FIRST to remove heavy buildup + metals for maximum K18PEPTIDE™ penetration.

SKIP CONDITIONER so it doesn't block the K18PEPTIDE™ from reaching the innermost layers of hair.

APPLY TO DAMP HAIR so the cuticle is swollen and able to accept the K18PEPTIDE™. If hair is too dry the peptide can't penetrate, if it's too wet the product gets watered down. Think about 65% wet.

WAIT 4 MIN before doing anything else. After 4 minutes, your healthy hair results won’t wash out—so comb + style as usual.
