Most nail problems are mechanical rather than nutritional. Nails split because they bend, peel because they get sawed at with a coarse file, and break because they are dry. Very little of it is about what you eat.
A nail that is painful, swollen, warm, separating from the bed, changing shape, or developing a dark streak is a medical question. So is a rash around the nail after using a product. None of that belongs on a blog.
The habits, in order of impact
- Oil daily. Cuticle oil is the single highest-impact thing on this list. A dry nail plate is brittle and a brittle nail breaks. Once a day, worked into the cuticle and the surrounding skin.
- Stop using the metal file. Anything coarser than 180 grit tears the layers apart at the free edge, and that is what peeling is.
- File in one direction. Sawing back and forth separates the layers even with the right grit.
- Wear gloves for washing up. Repeated wet and dry cycles are what soften a nail plate and make it bend.
- Do not use your nails as tools. Opening cans, scratching labels and prising lids account for most single breaks.
- Keep them shorter than you want them, for a while. A nail that keeps breaking at a certain length never gets past it.
- Push cuticles, do not cut them. The cuticle seals the gap at the base of the nail. Cutting it opens the seal.
- Use a base coat under dark shades. It prevents staining and improves adhesion.
- Take a break between enhancement sets if your nails feel tender, and oil daily through it.
- Do not peel gel or polish off. This is the fastest way to thin a nail plate.
- Buff sparingly. Once a fortnight at most, and stop as soon as the surface is even.
- Consider builder gel if nails bend and split. An apex stops the flex, and flex is the cause.
What does not work
- Nail hardeners used continuously. Most contain formaldehyde and make a nail rigid rather than strong. Rigid nails shatter.
- Biotin, unless you have a deficiency, which is rare. The trials showing benefit were mostly in people who were deficient.
- Garlic in the polish bottle. It is folklore.
- Soaking before filing. Wet nails are soft and tear.
Realistic timelines
A fingernail replaces itself in about six months, a toenail in twelve to eighteen. Nothing you do shows up in less than a few weeks, and a change at the cuticle takes months to reach the tip. Damage you can see now was done a while ago.
A routine that takes two minutes
- Oil in the evening, every evening.
- File once a week, dry, one direction, 180 grit.
- Push cuticles after a shower, gently, once a week.
- Hand cream whenever you wash your hands.

Questions people actually ask
How can I make my nails grow faster?
You mostly cannot. What you can do is stop them breaking at the length they currently break at, which is what makes them appear to grow. Oil daily and file properly.
Why do my nails peel?
Almost always a file that is too coarse, or filing back and forth. Both separate the layers at the free edge.
Do nail hardeners work?
Short term, and used continuously they make nails rigid rather than strong. Rigid nails shatter rather than bend. Use them for a few weeks, not permanently.
Does biotin help nails?
Only if you are deficient, which is uncommon. The studies showing a benefit were largely in deficient patients.
How long does it take to fix damaged nails?
A fingernail replaces itself in about six months. Improvements start at the cuticle and take that long to reach the tip.
