There is no proven way to encourage quicker nail growth. Fingernails typically grow at a rate of around 2 to 3 millimeters (mm) per month, while toenails grow at around 1 mm per month.
Taking care of your nails may help keep them strong and less prone to breakage.
Some tips for taking care of your nails include:
- keeping nails clean and short to prevent bacteria growing beneath the nails
- wearing gloves when washing dishes to reduce the risk of nails splitting or peeling from exposure to too much water
- avoiding using nails to open cans or other objects, as this can lead to splitting or lifting of the nail bed
- applying moisturizer after trimming your nails to prevent dry nails from splitting
- cleaning your nails with a soft nail brush rather than a hard brush or sharp objects
- avoiding biting your nails
- trimming injured nails to prevent them from catching on anything
- trimming toenails regularly
- wearing footwear that fits correctly and does not pinch your toes
- wearing flip flops in public showers and pools to reduce the risk of infection

There is no specific nail shape that is easier to maintain, but shorter nails are less likely to have a buildup of bacteria beneath the nails.
Nails with rounder edges are typically stronger. This can help reduce the likelihood of the nail breaking.
While keeping your natural nails short may be best for nail health, you may wish to wear artificial nails for more length.
Without proper care, acrylic nails and other false nails can damage the natural nail. Tips that can help reduce damage include:
- visiting a salon that uses LED curing lights rather than UV curing lights, as LED lights emit less UV radiation than UV lights
- opting for gel nails that soak off rather than acrylic nails, as gel nails are more flexible and less likely to crack the natural nail
- avoiding cuticle trimming before manicures or applying artificial nails
- only wearing artificial nails occasionally, such as for a special occasion, so that your natural nails have time to heal in between applications
You can speak with a dermatologist for more advice on the safety of artificial nails and steps you can take to protect your natural nails.

Some nail changes to look out for include:
- the nail bed lifting up, which could indicate psoriasis or a fungal infection
- spoon shaped nails, which could be due to:
- nutrition issues
- celiac disease
- issues with the stomach or intestines
- grooves or ridges in the nails, which could happen due to pushing back the cuticles
- onychogryphosis, or ram’s horn nails, where the nail thickens and becomes overgrown
- pitting, or tiny dots on the nail, which could indicate:
- psoriasis
- atopic dermatitis
- alopecia areata
- color changes, which could affect the whole nail or part of a nail
Nails may also change with some medical treatments. For example, some cancer treatments
