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 because 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.

I choose it because its like in your skin and you don't really think about it, but the periods I'm not bothered about :) weight gain I am :( I'm already 7st something I think..

I see. That makes sense. Like I said, diet and exercise is the only way. It doesn't have to be anything extreme. In fact, it shouldn't be extreme at all. Lots of fruits and veggies, lean proteins, no fried foods, junk food, soda.
