After your hair wash - this will work best as there will be very little barriers in the way. So always take advantage of a clean scalp.

Pop some all over the scalp or just on the areas of concern, massage in, pop some detangler/ heat protect into the ends of your hair and brush through and style as normal.

In between washes - spray Cellagen on dry scalp, distribute with fingertips, do not rinse. After application, the skin may show a red glow, this is a normal reaction and disappears after about 20 minutes. Apply twice a day (morning and evening if required).
