- Trim: Limit the damage by trimming back your nails. Make them short and round the sides with a file. Nails don’t grow very fast — no more than.12 inches (3 millimeters) each month — so don’t risk snagging them. The regrowth period for an entire nail can last three to six months.
- Moisturize: Dry nails lead to cracked nails. Apply a little moisturizer to your cuticles and nails each night to keep them supple but strong. A good moisturizer includes protein like keratin and collagen; occlusives such as petrolatum, mineral oil or lanolin; and humectants like urea or lactic acid.
- Avoid chemicals: Cleaning products or even some dishwashing liquids can make your nails dry and brittle. You can’t leave your home and dishes dirty, but you can experiment with less harsh products and limit your exposure.
- Consider gloves: If you’re often exposed to chemicals or if your hands are regularly wet, a pair of plastic or latex gloves can be a big help. Some people find plastic gloves uncomfortable, however. In that case, consider buying rubber gloves with a cotton lining.
- Limit remover: Using nail polish remover more than every two weeks can cause brittle nails. If you can’t cut back on the nail polish remover, at least buy those that don’t contain acetone.
