Peeling Nails: What to Check Before Blaming Your Manicure

Someone sits down, holds out a hand with layers flaking off the tips, and asks whether their last set did this. Sometimes the answer is yes. More often the manicure is the thing that made the problem visible, not the thing that caused it. This is the list we run through in the chair, in the order we run it.

Start with water, not polish

Nails soak up water and then dry out again, and every time that happens they swell and shrink a little. Do it all day, every day, and the layers of the nail plate start to separate at the free edge. That is the peeling most people describe. UPMC lists "dehydration from being in the water too long" among the causes of brittle nails, and MedlinePlus puts it plainly: "Long-term exposure to moisture or nail polish can cause nails to peel and become brittle."

Dish washing, hand washing, hair washing, a pool, a wet job. None of it is dramatic on its own. The AAD's tip is the boring one that works: "Wear gloves when cleaning or washing dishes, and make sure to moisturize after hand washing." Hand cream is good. Oil rubbed into the nail and the skin around it is better, because the nail drinks it.

Chemicals ride along with the water. UPMC names cuticle and nail polish removers; U.S. Dermatology Partners adds soaps and cleaning products, which "remove the protective natural oils from your skin and nails." Hand sanitizer counts too: UPMC notes that alcohol dries out nails and skin. If your job has your hands in any of that, the nails will tell on it before the skin does.

What the manicure can and cannot do

Now the honest part about our end. U.S. Dermatology Partners lists trauma to the nail as a cause of peeling: artificial nails can damage the nail plate, and rubbing it with a buffer or any tool can add to the problem. Their advice is to "ask the manicurist to leave your protective cuticles in place and not to buff too much." We agree, and you should feel free to ask.

Removal is where most real damage happens. Gel or dip that is peeled, picked or pried off takes layers of nail with it. Gel that is soaked off and lifted gently leaves the plate intact. That is why removal at Sora is a soak, not a pry, and why files and buffers are single-use (see our policy). If you have been picking off your own gel in the car, that alone can explain a set of thin, bendy nails.

The causes that are not the manicure

Some brittleness is just time. MedlinePlus says "brittle nails are often a normal result of aging," and UPMC notes that nail growth slows from age 25 and that nails get more brittle after menopause. Slower-growing nails sit in the world longer, collecting more wet-dry cycles before they are trimmed away.

Then there are the things a blood test can find and a nail file cannot. U.S. Dermatology Partners says iron-deficiency anemia can cause nails to peel and lists hypothyroidism, kidney problems, nail fungus and medicines such as chemotherapy and Accutane. MedlinePlus says "thyroid diseases such as hyperthyroidism or hypothyroidism may cause brittle nails." UPMC adds Raynaud's syndrome, anemia and cancer treatment.

Psoriasis deserves its own line because it looks different. The AAD describes nail psoriasis as "tiny dents in your nails (called 'nail pits')," crumbling, and nails "separating from your finger or toe." That is not wet-dry peeling, and no amount of hand cream fixes it. It is a dermatologist's job.

When to stop reading and book a dermatologist

We are licensed nail technicians, not medical providers, and this is where our part ends. The AAD's rule is simple: "If your nails change, swell, or cause pain, see your dermatologist because these can be signs of serious nail problems." Their list of 12 nail changes worth an appointment includes pitting, a nail lifting up, a dark streak, thin spoon-shaped nails and color changes.

U.S. Dermatology Partners puts it in terms of time: get an evaluation if you notice "changes to the nail that aren't resolving" after you have removed the likely causes. UPMC says your provider "may run tests to identify why you have weak or brittle nails." If you have diabetes or poor circulation, the AAD says it is especially important to get any nail problem treated. We will say so in the chair, but we cannot diagnose it.

Give it months, and do the boring things

Nails grow slowly. StatPearls estimates toenail growth "at approximately one millimeter per month" and notes fingernails grow faster; the AAD says growing out a nail "can take months," and on the big toe "a year or longer." Whatever you change today, the nail you are looking at was made weeks ago. Judge progress at the base, not the tips.

While you wait, the AAD's routine is short. Cut nails straight across and use a file to slightly round the corners. "Always file the nail in the same direction, as filing back and forth can weaken your nails." Do not use nails as tools. Do not bite them or cut cuticles. UPMC suggests going polish-free for a few months, rubber gloves for dishes and cleaning fluids, and a paraffin bath for dry nails.

One thing UPMC separates that most people lump together: dry, brittle nails want more moisture; soft nails that bend rather than snap "may have gotten too moist," so cut back on lotions and oils on the nail itself and try a strengthening polish. Either way, skip hardeners with formaldehyde and go easy on acetone removers.

What to ask for

Tell your tech the nails are peeling and ask for a classic manicure with minimal buffing, or ask whether a builder gel overlay makes sense for nails that split past the fingertip. If we think the right answer is no enhancements for a while, we will say that rather than sell you another set. And if anything on the AAD list above is true of your nails, book the dermatologist first and come see us after.
