1. How much product should I actually use?

For fine or short hair, start with just one pump. For medium-length or thick hair, 2 pumps should be perfect. For very long or coarse hair, you might need 3 pumps. Always start with less and add more if you feel certain sections weren't covered.

2. How often should I use the mask for the best results?

For a total transformation, use it for the first 4-6 consecutive washes. After that, you can switch to maintenance mode and use it every 3-4 washes to keep your hair in its absolute best condition.

3. Can I heat style after applying the mask?

Yes, you certainly can. After the 4-minute activation period is complete, you are free to blow-dry, flat iron, or curl your hair as you normally would. The mask actually helps fortify your hair against heat damage.

4. Is this safe for my color-treated or keratin-treated hair?

Absolutely. The mask is fabulous for all chemically treated hair. It works on a molecular level to repair the damage caused by these services, making your hair stronger and more resilient, which can even help your color look more vibrant.

1. Prepare Hair: Shampoo, but skip the conditioner. Towel-dry your hair until it's just damp. This prepares your hair for the treatment.
2. Apply the Mask: Dispense 1-3 pumps of the K18 Molecular Repair Leave-In Mask into your hands. Distribute it evenly from ends to roots. A little goes a long way.
3. Let It Sit: Wait exactly 4 minutes for the K18Peptide™ to penetrate and work its magic. Do not rinse. This is where the transformation happens.
4. Style Confidently: After 4 minutes, comb and style as you normally would, using heat if you like. You'll immediately notice the incredible softness, smoothness, and bounce.
