For the best results, Frizz Ease Original 6 Effects Serum and Frizz Ease Extra Strength 6 Effects Serum need to be applied to soaking-wet hair. You will not be able to spread it through dry hair. The excess water allows these serums to better spread throughout the hair so each strand is covered evenly. In addition, rough towel drying can further roughen the hair cuticles and create frizz. If you need to remove excess water to prevent dripping, gently blot the ends of your hair with a towel before applying these serums.
