Minoxin Hair ReGrow 5% Plus Hair Loss Treatment Korean

How is minoxin 5% plus to treat hair loss ?
hello doctor i am 20 years old female. i am excessively losing my hair . i started applying minoxin 5% plus. initially it stopped my hair fall for atleast a month. and i can even see my small hair grow. but its been 3 months now my hair have started shedding again. i read it on net that minoxin initially causes your hair to shedd. i just wanted to confirm is it normal. i am really worried. i actually feel like crying when i see loads of hair every morning on my floor. and for how long this shedding will continue as a result of minoxin.
