Can I use the wig for some time after transplant? I will quit once the hair grows.

You may use hair piece after 15 days of transplant with some care when the wound have healed and then remove it once the transplanted hair grows. You must know that transplant will never give you as much density as the hair piece or wig can give and there for it is better that you get the hair piece trimmed to lighter density serially before you finally quit it . But still better method s shave the head completely during the transplant and maintained like that for 4-6 months and after that and let the transplants grow with other hair thereafter.

I read about the side effects ; should I stop Medications?

Every thing you read on internet may not be written in the right perspective. Minoxidiil may be very rarely a possible cause of hepatic ( liver) damage but when it is consumed orally and not when you apply it on the scalp. Same way Finasteride side effect is mainly reduced sexual libido ( a psychological manifestation) and not really impotency or sterility ( organic manifestations) more over this is very well studied to be experienced by only 1% of those who use it and majority of the time that is experienced in initial few weeks. Most important and interesting is the sexual symptoms are reversible on stopping the medication and it has been seen that many of those who have continued in spite of the experience of initial sexual symptoms had observed that the said side effect disappeared. By not taking this you lose a chance of falling in to 99% of those who do not have such side effect and have benefit of medication. for more ref to:

http://goodbyehairloss.blogspot.com/2010/01/hair-loss-and-medications-finasteride.html If you have been using this medications for long time and you already had benefit if improving your the thickness and length of your miniaturized hairs you may start rapidly losing those hairs which are supported by the medications if you suddenly stop the medications. Minoxidil is better used as 5% instead of 2% for more efficiency and use twice instead of oncee a day. In my experience Instead of plain Minoxidil as you have been using; use the combination with Reti-A which is more effective and have to be used once a day. check: http://goodbyehairloss.blogspot.com/2010/01/minoxidil-with-retin-or-minoxidil.html Finasteride is better than Minoxidil in effect when used alone but since both medications have different mechanism of action there is more benefit when used in combination.
