When you’re taking exemestane, a type of aromatase inhibitor used to treat hormone-receptor-positive breast cancer. Also known as Aromasin, it lowers estrogen levels to stop cancer growth—but that same drop can trigger hair thinning in many women. This isn’t just cosmetic. For some, it’s one of the most distressing side effects, affecting confidence and daily life. The good news? Hair loss from exemestane isn’t always permanent, and there are real, science-backed ways to manage it.
Exemestane belongs to a class of drugs called aromatase inhibitors, medications that block the enzyme responsible for turning androgens into estrogen. When estrogen drops, hair follicles can shrink, leading to diffuse thinning, especially on the top of the scalp. This isn’t like male-pattern baldness—it’s more like your hair feels finer, less full, and sheds more than usual. Studies show up to 20% of women on aromatase inhibitors notice some level of hair thinning, but only a small fraction experience severe loss. The key is catching it early and acting smart.
Not all hair loss remedies work here. Biotech serums, expensive laser caps, or unproven supplements won’t fix a hormonal root cause. What does help? First, minoxidil, a topical treatment approved by the FDA for female pattern hair loss. Applied daily, it can slow shedding and even regrow some hair, even while you’re on exemestane. Second, iron and vitamin D levels, two nutrients often low in women on hormonal therapies. Low iron = more shedding. Low vitamin D = weaker follicles. Get tested. If you’re deficient, fixing it can make a noticeable difference. Third, avoid tight hairstyles, heat tools, and harsh chemicals. Your hair is already under stress—don’t add more.
Some women wonder about switching drugs. Let’s be clear: exemestane is often the best option for preventing cancer recurrence. Stopping it just for hair loss isn’t recommended. But if thinning is severe, talk to your oncologist. There are other aromatase inhibitors—like anastrozole or letrozole—that might affect hair differently. No one size fits all, and your team can help you weigh trade-offs.
What you won’t find here are miracle cures or vague advice like "eat more greens" (though that’s fine for general health). This isn’t about boosting estrogen—it’s about supporting follicles while your body adjusts to lower levels. The posts below cover real cases, practical routines, and what doctors actually recommend when hair loss shows up during hormonal therapy. You’ll find what works, what’s a waste of time, and how to talk to your doctor without sounding alarmist. This isn’t just about hair. It’s about keeping your sense of self intact while staying on treatment that saves your life.
Exemestane can cause gradual hair thinning in up to 30% of users. Learn the science behind it, what actually helps, and how to cope emotionally without compromising your treatment.
