i realize that wearing a cap doesnt make you go bald but it is VERY detrimental those with a new h/t! i am now 1 month post op. i had hair added to both the crown and front. i wore a cap from day 1 to try and conceal the surgery, being more than careful not to rub the cap front against the new transplants (wearing it way down on my forehead. just fyi-i have lost nearly all the hairs along my front hairline and still have all the hairs that were transplanted on the crown. i know just the friction of putting on and taking off the hat is what made them fall out in front. they very well may come back/or not but if you want to hang on to themfor long as possible...dont do the cap thing!
