Remove scalp and hair plaster from the refrigerator an hour before use to bring it to room temperature.
Start the process with dry hair, separated into small sections. Using your fingertips, scoop out a large dollop of plaster, and gently massage it into your scalp, pressing down to the ends of each strand. Repeat this system until your full head of hair and scalp are saturated with the plaster. Use the entire serving of the plaster.
Depending on your hair’s health and nutritional needs, leave plaster in place from 1 to 3 hours.
To remove, do not get hair wet! Apply a generous amount of shampoo directly onto plastered hair, from scalp to ends. Then add a small amount of water to create a light lather. Proceed to shampoo hair as usual, rinsing thoroughly until water runs clear. A second shampooing may be needed.
Follow up with conditioner if desired.
