Spectral RS - How To Use

Spectral RS should be applied twice per day, whether your hair has been washed or not.

Since there is no possibility of side effects, it is possible to apply Spectral RS three times per day to accelerate the results. With twice per day use, a bottle of Spectral RS will last approximately 30 days.

For best results, it is important to apply Spectral RS regularly without skipping applications.
