Well, I am glad tgat you actually tried and it work for you guys though partially to begin with.
I can suggest many erotic and exotic things that can bring back the lost pleasure ..would you be interested then wait for my email.
Until then, do remember wig can be just a temporary solution, the ultimate objective of your wife should be still to grow her hairs long..infact very long to revive the lost glory and not just look for easy alternate.
