For a windblown, well-textured look, work Reuzel Surf Tonic through damp or nearly dry hair with your fingers; blow dry if desired.
For a smoother look with volume, spray the tonic as you comb upward, aiming for the middle of the hair shafts. Let air dry for rougher texture, or blow dry for smoother results.
You can also use Reuzel Surf Tonic Spray on towel-dried hair for volume and finish with additional product like matte styling paste for more aggressive texture and stronger hold.
