1) Each XYON bottle has a built-in safety lock. Turn the safety lock to the open position and press down once to dispense a pre-measured amount (1 mL) of treatment. 2) Focus application of XYON topical finasteride to the affected areas of the scalp. If you have long or curly hair, you can try parting your hair to better access the scalp skin. Gently massage the treatment into the scalp for 20-30 seconds. 3) You're done. Style your hair as usual, but make sure that you wash your hands with soap and warm water after applying and/or touching the gel.
