after shampooing your hair, dry your hair enough with a towel then spray  directly the hair loss area that  you have. After 30 minutes, apply one ml 2times a day with MINOXIDIL(3% for wemen, 5% for men).  You can get marvelous synergy effects.  If you want to have a younger face,  spray it on your face two times a day.   More in details, please refer Wikipedia (copper peptide GHK-Cu)
