Nexplanon
"If you have any sort of history of hair loss in your family, do NOT get this birth control. It's high in androgenic activity, which in turn can cause hair follicles to shrink and lead to hair loss. I have VERY thick hair, and I had been on Nexplanon until a little over a week ago when I got it removed. I had for it a little over a year, but the hair loss was so gradual, I didn't notice it until recently after taking a shower and realizing that my scalp was a LOT more visible than it normally is. Now, I'm consulting with my GP and a dermatologist to get my iron and hormone levels checked to make sure there's not any lasting damage. I'm also taking a hair/nail supplement, but I'm told hair regrowth takes a year at least."
