How to use Strengthening Duo: Strengthens and Stimulates ?

To preserve the long term vitality of your hair, the serum should be used before each shampoo. As part of an intensive one month treatment, it can be left on overnight once or twice a week.

Spray the serum directly onto the scalp, close to the roots, parting the hair to ensure even coverage. Gently massage to activate circulation, help remove impurities and promote the diffusion of active ingredients into the upper layers of the epidermis. Leave on for ten to fifteen minutes, or overnight for a more intensive treatment, then rinse thoroughly before shampooing.

The serum can be perfectly combined with the mask, as each addresses different hair needs and can be applied at the same time. Before shampooing, apply the serum to the scalp to purify and rebalance it, massaging gently. At the same time, apply the mask to the lengths and ends to nourish and repair the hair fiber. Leave both treatments on for ten to fifteen minutes, then rinse thoroughly.
