You started birth control for many reasons, but finding more hair in your brush or shower drain probably wasn’t one of them. It can be a surprising and worrying side effect. The short answer is yes, certain types of birth control can contribute to hair loss. The good news is that this is often temporary and manageable once you understand the connection.
The Hormonal Link to Your Hair
Hair loss related to birth control is almost always tied to hormones. Many contraceptives work by manipulating your body’s natural hormone levels to prevent pregnancy. Some pills contain progestins (synthetic progesterone) that have “androgenic” activity. This means they can mimic male hormones in your body, which can sometimes cause hair follicles to shrink and lead to a type of hair thinning called telogen effluvium.
Which Types of Birth Control Are More Likely to Affect Hair?
Not all birth control is created equal when it comes to this side effect. Older, first-generation progestins like norethindrone or levonorgestrel tend to have higher androgenic activity. Low-androgen or anti-androgen pills, however, are often a better choice for those concerned about hair. These include options with progestins like norgestimate, drospirenone, or desogestrel. If you’re noticing changes, it’s a great topic to discuss with your doctor.
What to Do If You’re Experiencing Hair Loss
First, don’t panic. This kind of hair loss is usually temporary. Your body is likely just adjusting to the change in hormones. It can also happen if you stop taking the pill, as your body goes through a hormonal shift. If the thinning continues for several months, talk to your healthcare provider. They can help you determine if your birth control is the cause and may suggest switching to a different formulation with a lower androgen index.
Supporting your hair health during this time is also key. Eating a balanced diet rich in iron, protein, and vitamins, managing stress, and using gentle hair care products can all make a positive difference. Remember, you’re not alone in this experience, and there are steps you can take to help your hair recover.
