Does hormonal coil (IUS) cause hair loss?

I’m 44 with recently diagnosed PCOS and endometriosis which is why my specialist told me to try the Mirena to lighten the lining of my uterus and help with my awful periods. I had to go off of the pill at 40 and suffered for 2 years while debating what to do. I got the mirena in at 42 and have had it 2.5 years now. I do get pelvic pain and cramping twice a month for a few days randomly and feel like I can tell which ovary is active but it is still better than dealing with the bleeding and irregular periods I had previously. My periods are non existant apart from spotting for a few days but not enough to even merit wearing a liner! Sex drive is definitely lower and dryness comes and goes as well but breasts have grown which I’m not upset about! I’m leaving it for another 2 years then will decide if I should opt for a hysterectomy.

After being on and off oral contraceptives (most of the time cyproterone acetate 2.00 mg and ethinylestradiol tablets 35 mcg) I found moving to a hormonal IUD to be a total game-changer. Positives: Predominantly for my moods and the feeling of being in tune with my body (less water retention etc.). Although my hormonal prone acne got worse for a period of time (2-3 months), this eventually came right. I also lost the positive anti-androgen effects that I was on the pill for. I would say the improvement in mood was so significant for this alone it was worth switching the IUD. Other benefits; not having to think about the pill every day and going from heavy bleeding to light and then non-existent bleeding. Negatives: After nearly 1 year and a half of having the IUD I had a recurring UTI and several courses of antibiotics. I developed lower abdominal pain, bloating, pain after sex and thrush. This would come and go. Results only came back with BV. My gynaecologist suggested a course of Uro-Vaxom (3 months). This didn't resolve my symptoms so I suggested I would like to remove the IUD to see if it would help getting my periods back to rebalance my vaginal microbiome. After removing the IUD and two menstrual cycles later, all my symptoms were gone. I would still highly recommend this contraception - I had zero problems and only benefits up until the UTI and antibiotics.

Insertion not too bad, just a small quick pain. Found to be a good contraceptive over 8-9 months - no weight change/mood change. A little uncomfortable during sex. Main issue was the dramatic hair loss. I lost around a quarter of my hair around hairline and in volume. Had removed for this reason.
