What Causes Brittle Nails During Menopause?

Nails are the most underrated part of the body. They’re strong, durable, and constantly growing and renewing themselves, no matter how many times they’re cut down to size. (Brené Brown, who?) 

But if you’re going through menopause, you might have noticed some major changes in your nails — thinness, split ends, breakage, you name it. Unfortunately, brittle nails are a symptom of menopause, albeit one of the less obvious ones (ahem, hot flash). Why that is, experts aren’t totally sure, but here’s what is known about menopause-related brittle nails, and how to get yours manicure-ready in no time. 

What Causes Brittle Nails During Menopause?

Nails are considered “brittle” when the nail plate (the pink part of the nail) becomes weak and fragile and may split, crumble, or flake as a result. In dermatologist speak, this condition is called Brittle Nail Syndrome (BNS), and an estimated 20 percent of the population experiences it. Women are twice as likely to experience BNS compared to men, with women over the age of 50 being particularly at risk. 

If you have brittle nails, you might have vertical ridges running up and down your fingernails. (These ridges might even split or crack, depending on how brittle your nails are.) Your nails might also peel and flake like sunburnt skin, or have tiny flecks of white all over the nail. 

You can get brittle nails for a number of different reasons. Constantly washing and drying your hands (say, if you’re a teacher, doctor, or just trying to practice good hygiene during a pandemic) can mess with your nail structure and make them brittle. Leaving nail polish on for too long, going overboard on nail treatments, having overly-long nails that break, or doing manicures incorrectly can also damage your nails and leave them brittle. Common skin conditions like psoriasis and eczema can also contribute to brittle nails, as can fungal nail infections. Constant contact with chemicals (like detergents or cleaning agents) can also trigger brittle nails. 

Frustratingly, the most common type of nail brittleness is “idiopathic,” which is science speak for “it just randomly happens.” 

Unfortunately, our understanding of the relationship between brittle and menopause is almost non-existent because researchers haven’t yet compared the instances of brittle nails in premenopausal versus menopausal women. Our best guesses right now: Some aspects of women’s nail structure are weaker than men’s, which could partly explain why women are more likely to deal with brittle nails than men. While everyone’s nails get duller and more brittle with age, post-menopausal women tend to have less of a key lipid in their nails that maintains nail structure and health. Some researchers believe that the hormonal changes that begin in perimenopause may also contribute to brittle nails—and, certainly, many anecdotal accounts from menopausal women appear to confirm this—but no scientific link has been made… at least, not yet. 

Remedies for Brittle Nails 

Brittle nails are largely treated with supplements and lifestyle changes. Here are some of the most commonly recommended treatment options: 

  • Try biotin supplements: Biotin, aka B7, gets a lot of clout for strengthening your skin, hair, and nails. Although it hasn’t been widely researched, one small study found that folks taking a biotin supplement every day saw a 25 percent increase in the thickness of their nails. Five to 10 milligrams per day should cut it. However, check in with your doc before trying biotin to make sure it doesn’t mess with any other medications you take. (Biotin can also affect lab test results, so keep that in mind when you get bloodwork.)
  • Moisturize, moisturize, moisturize. If you wash your hands a lot—or frequently get your hands wet—use a heavy-duty moisturizer on your hands and nails immediately after toweling off and before bed. Look for a formula that has petrolatum, glycerin, or alpha-hydroxy acids to get the most benefit.
  • Skip the soak: As discussed earlier, brittle nails can be the result of too much water exposure. Consider cutting down the time you spend in a swimming pool or submerged in your bath. 
  • Protect your hands: It’s a good idea to wear gloves (vinyl for wet work, cotton gloves for dry work) if your job requires you to regularly use chemicals or harsh cleaners.
  • Prioritize protein. Your nails (and skin, and muscles, and everything else) need protein to stay strong. Eat at least 45 grams of protein per day. 
  • Avoid gel manicures: Gel manicures are so cute, but they cause a lot of damage to your nails when they peel off. Consider applying a clear coat and waiting for the polish to naturally come off on its own. 
  • See a dermatologist. As mentioned earlier, brittle nails can be caused by other skin conditions or infections. Treating the underlying cause with the help of a trained derm may help banish brittle nails for good. 

  • Related Nail Symptoms During Menopause

    While there are no other nail symptoms in menopause that have been widely studied, you may notice other changes in your skin and hair during the menopause transition. As your natural estrogen levels start to decrease, you start to retain less moisture in your skin, and you may notice dark spots, dry or flaky patches of skin, and/or hair thinning. 

    If any of these symptoms crop up, make sure to talk to your doctor about potential ways to lessen the burden of these exterior signs of menopause. 

    When to See a Doctor for Your Brittle Nails

    The American Academy of Dermatology Association (AAD) says you should should see a dermatologist if your nails:

    • Change color (turn white, for example, or develop dark spots or lines)
    • Change texture (you start seeing pits or thick grooves or ridges)
    • Change shape 
    • Stop growing
    • Bleed 
    • Separate from the surrounding skin
    • Swell  

    These symptoms could be a sign of something more serious going on. (Completely white nails, for example, is a sign of anemia.) While the transformation may be completely benign, erring on the side of caution is the way to go. So start a dialogue with your MD if you notice that your nails don’t look quite right. 

    A final note

    We’ll go bad news, good news—okay? The bad news: Researchers don’t yet know a lot about why menopause may wreak havoc on your nails. The good news: There are plenty of remedies you can try to strengthen them. Time to put this frustrating nail issue to bed.
