Suggested Usage:
-While in the shower, massage detox shampoo into hair and scalp to remove excess buildup.
-Thoroughly rinse.
-Repeat as needed.
-Skip conditioner.
-Once out of the shower, gently towel dry hair until damp.
-Begin with one dime-size amount of K18 Mask.
-Only add more as needed. The average use is two dime-size amounts. This is a highly concentrated formula, so you‘ll need much less than traditional masks.
-Work evenly into hair from ends to roots.
-Let sit for four minutes.
-Don‘t rinse out.
-Style as usual after the four minutes is up. It’s now fine to add heat protectant or styling product.
-Use for the first four to six washes, then swap to maintenance mode and use as needed.
