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. 

For normal hair: after shampooing, apply to towel dried scalp and hair for 3-5 minutes, comb and rinse.

For fine hair: can also be used as a pre-shampoo treatment for a light conditioning effect. In this case, apply to scalp and damp hair, leave on for 3-5 minutes, then rinse and shampoo.

For normal to thick hair: apply the product as a pre-shampoo treatment and leave on for 3-5 minutes. Proceed to rinse and shampoo. After rinsing, apply conditioner again, leaving on for 3-5 minutes before rinsing. Proceed to dry hair. Apply as frequent as needed, in combination with the products of the Renewing family.
