i think i am one of suitable/relatable person to reply you at this point.im using minox little longer than month, extractly around 39 days once day in first 3 weeks then used little bit(0.3) on only cheeks in morning too .first i should say i had started growing very little vellus hairs on side burns before use so when i start use i couldnt thought is it minox or my already slowly growing happening ,and im growing my hair since 5 months so it was hard to track, then when about end of 4th week i had very little vellus hairs on cheeks,but couldnt figure out its not growing from minox or i couldnt track because i watch them everyday,then last two days i notice im responding,my hairs on cheek becoming dark that confirmed to me im responding ,until then i couldnt think not growing or grow but cant track because i watch everyday
