Step 1

The Application starts with washing the hair twice with GKhair pH+ Clarifying Shampoo. The Clarifying Shampoo preps the hair for the Juvexin treatment and removes excess build up and styling products from the hair. Wash hair twice with the GKhair pH+ Clarifying shampoo and 3 times with virgin hair. Towel dry and brush the hair.

Step 2

Section the hair in ½-inch each and use the application brush to apply “The Best” on each ½-inch section of hair. DO NOT APPLY ON THE SCALP. Be sure to stay ¼-inch away from the scalp while combing or massaging the product through the hair. Be generous with the strokes as all of the hair needs to be saturated in order for the treatment to have maximum effect.

Step 3

Allow the product to sit on the hair for 40 to 60 minutes.

a) 40 minutes for fine, wavy hair

b) 60 minutes for thick, coarse, tight curly hair to maximize the smoothing results. Cover the hair with a plastic cap.

Step 4

Rinse the hair with warm water until the products runs clear out of the hair. If hair is over-processed or red, shampoo the hair with GKhair Moisturizing Shampoo focusing on the ends to remove excess product.
