hello doctor, im 22 yrs old I was having severe hairfall for the past 5 years, i started using minox+finpecia 4 months back, my hairfall stopped after 2 months, but I have been working in night shifts for the last one month, and now i see that my hairfall has once again started as it was when I started using the minoxidil 4 months back, is this ordinary, or am I not responding to the medication , or should I stop working in night shifts.
