I had the implanon put in back in feb of this year. I didnt notice the loss of curls right away as I went travelling and blamed it on change of water and the sun. However after coming back home I realised that my hair is now has a tendency a) to be a lot more greasy - it used to be dry and b) its now only wavy. I am thinking of having it taken out as this was never a problem when I was on the birth control pill. I feel a little like Ive lost my identity! My curls were def one of my best physical features. I will let you know how it goes!
