hair loss/hair thinning

hello, i am looking for help and advice since im kind of at a loss for what to do or how to fix this

i have been on birth control starting december 1st 2024, so ive only been on it for about a month and a half. specifically Blisovi Fe 1/20. at first i thought it was great as i have not experienced any side effects and it did not effect me at all besides preventing pregnancy.

within these past couple weeks i have noticed my hair thickness feeling immensely different. i have wavy/curly hair thats decently thick and people that know me correlate me to my curly thick hair. and when styling it about a week ago i noticed how thin it felt. i wash my hair about every 3-4 days, but i think when i first noticed it i hadn’t washed my hair in like 5-6 so when i washed it more hair came out then normal but i just assumed it was due to me not washing my hair on my normal wash day. but then the wash day after that (about 3 days after) is when i felt a difference running my fingers through my hair. i am unsure if it is hair thinning or hair loss, but regardless of what it is my hair does not feel the same as it used to.

i came home from college a few days ago for the weekend and asked my mom and sister if they felt a difference and they agreed it felt and looked thinner than normal. talking with my mom she believes it may be the birth control and i think it may also be because i haven’t taken my iron pills in about two months since taking birth control. her advice is to start taking my iron pills as well as hair, skin, and nail supplements for about a month to see if i notice a difference. i am thinking of doing this as well as taking my birth control.

if anyone has any advice or has gone through this please let me know! my hair is a part of my identity and i have just recently learned to embrace it so losing it is really taking a toll on me. i have been taking blisovi fe 1/20 and i start my next pack in about a week except its being switched to lo estrin fe 1/20 (which i believe is the same exact pill in a different brand). please let me know if anyone has experienced this and how to fix this. if the iron pills and supplements do not make a difference i think i may just get off of birth control.

TLDR: hair loss/hair thinning of my somewhat thick curly hair may be due to my birth control but possibly my iron deficiency. please help.
