Thanks for the query.
It might be a side effect of minoxidil
therapy or may be unrelated to it.
Yes it can be removed by LASER
Another option is eflora cream,
I would suggest you to use this cream first,
If there is no response you can go for LASER.
Please meet a dermatologist
and discuss regarding this.
