Brittle, Peeling Nails: 7 Home Fixes That Actually Work

Nails that split at the tip, peel in thin layers or snap the moment they pass your fingertip are one of the most common complaints we hear. The good news: in most cases the cause is mechanical and environmental, not mysterious, and a few home habits change the picture in three to six weeks, the time it takes for new nail to grow out.
This is cosmetic guidance. If a nail hurts, lifts from its bed, changes color suddenly or shows a dark band, see a dermatologist.
Why nails peel in layers
The nail plate is made of dozens of thin, overlapping layers of keratin held together by a little water and natural lipids. Every time your hands go in and out of water, the plate swells and shrinks. Do that twenty times a day, add dish soap or acetone, and the layers start to separate at the free edge. That is peeling. Brittle nails are the same story one step further: the plate has lost its flexibility and cracks instead of bending.
1. Gloves before water
It sounds too simple, but it is the single habit that moves things the most. Dishes, cleaning, washing a child's hair: wear gloves. Your nails stop the swell-and-shrink cycle that splits the layers.
2. Castor oil every evening
One or two drops per nail, massaged for a minute before bed. Castor oil is thick and clings to the plate and the skin around it, keeping the layers supple overnight. Consistency beats quantity: every night for three weeks does more than a lot of oil once a week. Read our guide to castor oil for nails.
3. File in one direction, with glass
Sawing back and forth with a metal file tears the layers apart at the tip. A glass file, moved in one direction from the side toward the center, seals the edge instead. More in how to file your nails.
4. Keep them short for now
A long nail is a lever: every knock is transmitted to the weakest layer. Keep a short squoval or oval shape while the new nail grows in. See the nail shapes guide for the shape that suits your fingers.
5. Take a break from gel and harsh removal
Soaking in pure acetone and scraping off gel strips the top layers. If your nails are already fragile, give them a few weeks off, or have gel removed gently.
6. Moisturize the hands, not only the nails
Shea butter or a rich hand cream after each wash keeps the skin around the nail soft, and the cuticle is the nail's seal. A dry, cracked cuticle lets water in and out of the matrix faster.
7. Look at your plate, literally
The nail grows from the matrix under the cuticle, so what you eat shows up months later. Protein (eggs, lentils, fish) and a varied plate matter more than any miracle capsule.
How to know it's working
Take a photo of your nails today and another in two weeks, in the same light. The Ongles Paris app does exactly that: one photo of each hand gives you a strength score and a home routine built around it, and it reminds you to rescan in 14 days so you can see the curve move.
