"if you have any sort of history of hair loss in your family, do not get this birth control. it&#039;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&#039;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&#039;m consulting with my gp and a dermatologist to get my iron and hormone levels checked to make sure there&#039;s not any lasting damage. i&#039;m also taking a hair/nail supplement, but i&#039;m told hair regrowth takes a year at least."
