New Birth Control: Implanon TOP RESOURCE (http://www.epigee.org/guide/implanon.html)
i can't find anything about hair loss. weight gain is a possible side effect of numerous hormonal birth controls. make sure you eat healthy and have a regular work out or exercise routine.
i am a little bit curious why you chose this bc method out of everything out there, if you don't mind my asking. it sounds like there's a lot of possible negative side effects and personally it would drive me crazy if it didn't make my period regular. but maybe that's just because i know so little about it.
