Here’s a heads up for all transitioners and naturalistas (people who are growing their relaxers out instead of cutting off all of their hair). Did you know that taking and/or switching your birth control pills can lead to hair loss? I know, this is the worst thing to hear as you are trying to grow your hair out, but it happens. Because birth control pills cause changes in your hormone levels, one of the side affects is hair loss. This change causes the androgen receptors (male hormone) to activate, thus minimizing hair follicles and leading to hair loss. (Fox News)
If you are taking birth control pills and are worried about this or are experiencing hair loss, talk to your doctor about switching back or switching to a new birth control pill.

Very true, being on birth control caused my hairline to be almost non-existent. Of course I stopped taking them as soon as I realized it was causing my hair loss. It took a long time and a lot of hair treatments for my hairline to grow back.
From my experience the hairline is the hardest hair to grow back. Sometimes once it’s gone, it’s gone.
I know! I had to change my pill 3 times until I found one that didn’t make me go bald lol. Strangely, I was mainly using hair from the center of my head versus my hairline 0_0
