Always shampoo the hair and scalp twice. A euro sized amount of shampoo is more than enough. Create a lather in the hands and pop it into the scalp. Spend 30 seconds massaging the scalp, ignoring the hair. After the 30 seconds rinse well. 

Your second shampoo should be half the amount of product. Again, lathering into the hands and straight onto the scalp, this time you should get a much greater lather even when using half the amount of product. This time involve the ends of your hair very gently and leave for two minutes, bringing under the hairline. Rinse well. 

After shampooing, apply to towel-dried lengths and ends. Leave on for a few minutes, comb through and rinse thoroughly.

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).
