These are the best nail strengtheners and treatments for stronger, healthier nails.

If you struggle with brittle, weak nails, then you’re in good company. It’s actually fairly common for nails to peel, split, and break. Frequent hand-washing and sanitizing during the coronavirus pandemic could be the culprit. So can age, iron deficiency, and too many trips to the nail salon. 27 percent of women have brittle nails (or onychoschizia), according to Harvard Medical School.

There are two basic types of brittle nails: dry and brittle (caused by too little moisture) or soft and brittle (caused by too much moisture). Repeated hand-washing, dry heat, and lack of humidity can contribute to dry nails. Excessive exposure to the chemicals in nail polish removers and cleaning products can cause soft nails. For strong, healthy nails, it’s all about achieving just the right amount of moisture for your nails — not too little and not too much.

Once you’ve diagnosed the problem, it’s pretty easy to course correct. To treat dry and brittle nails, apply a moisturizing strengthener that’ll restore much-needed hydration. Make sure to cut, shape, and file your nails regularly to help prevent further breakage. For soft and brittle nails, wear rubber gloves while washing the dishes or performing any other household chore that involves getting your nails wet. Apply a weekly nail strengthener that improves your nail’s thickness and health, steering clear of formulas with formaldehyde in them.
