Hello Sana ma'am,
So as you must be knowing minioxidil topical lotion is teh FDA approved drug used to control hair fall , its used in both male and female pattern of hair fall , It is used to preserve the exiting hair even it is adviced post hair transplant surgery for the growth of transplanted hair . The adviced dose of minioxidil topical lotion is 1ml twice in day morning + night application.
As per the studies conducted and researches done on the absoprtion of minioxidil , it has been noted taht the absorption of minioxidil in 1 hour after application is about 30% to 40%
After 4 hours the absoprtion is about 60% to 75% , and in 8 hours time its absorption is almost 80 -90%. So ideally it is adviced to keep minioxidil for 8 hour for good results or good action of the medcine.
Also after application let the lotion get dried up on our scalp properly it will take minimum 20 to 30 minutes for the lotion to absorb on scalp then you can wear your cap or helmet post application, but let it dry .
Even at night time application let it dry then you can go to bed , or sometimes immediately after application few people go the sleep so it may get absorbed on bed or pillow and can get in contact with your face or ears, so it may lead to excess facial hair growth , so mostly it is adviced to dry up the minioxidil prropely after application then u can do your daily routine.
You are doing right as of now
Also wash your hands post application of minioxidil.
