Fast nail growth doesn't necessarily mean good health
While poor health can slow nail growth, fast nail growth doesn’t necessarily mean good health. There are a number of factors that can affect the rate of nail growth, including which hand it is, your age, hormone levels, and overall health. The nails on your dominant hand grow faster than the rest, as do the nails on your longer fingers. Toenails, for example, grow three times slower than fingernails because they are subjected to less trauma.
Fingernails are a window to your health. They are made up of layers of the protein keratin and grow from beneath the base of the nail under your cuticle. As new cells grow, older cells become hard and compacted and are eventually pushed out toward your fingertips. While there aren’t any scientifically proven methods to make nails grow faster, there are a number of ways to increase the overall health of your nails.
Nutrient deficiencies may affect your nails' appearance. For example, erythema multiforme can cause oral symptoms such as ulcers.

Poor health can slow nail growth
While fast nail growth doesn't necessarily mean good health, poor health can slow nail growth. Fingernails grow at an average rate of about a tenth of a millimetre per day, or 3.47 millimetres per month. However, this rate can vary depending on factors such as which hand it is, your age, hormone levels, and overall health. Poor blood flow to the area can slow nail growth, and researchers have found that applying a 5% minoxidil solution to the nails stimulates blood flow and promotes nail growth. In some cases, a change in your nails may be caused by stress in your body. For example, if you have a high fever, a serious injury or infection, or another severe illness, your nails may stop growing for a while. This is because your body shifts energy away from the low priority of growing nails to focus on healing. Your nails are made up of layers of the protein keratin and grow from beneath the base of the nail under your cuticle. As new cells grow, older cells become hard and compacted and are eventually pushed out toward your fingertips. Nutrient deficiencies may also affect the appearance of your nails.

Nutrient deficiencies can affect nail appearance
While poor health can slow nail growth, fast nail growth doesn’t necessarily mean good health. Your fingernails can say a lot about your health, and nutrient deficiencies may affect your nails' appearance.
Nails are made up of a protein called keratin, which your body needs nutrients to produce. You also need healthy fats and oils from your diet to keep your nails strong and moisturised. Nutrient deficiencies that can affect nail appearance include iron, zinc, calcium, and vitamins A, B, C, and E. Nails can become rough, weak, or brittle due to nutrient deficiencies.
Malabsorption syndromes, such as conditions affecting the gut’s ability to absorb nutrients, can contribute to vitamin deficiencies. Excess alcohol consumption can also interfere with the body’s ability to absorb nutrients. Certain medical conditions can also impact the body’s ability to absorb or utilise vitamins properly.
If you notice any nail changes, it is important to talk to your doctor or a dermatologist. They can help you figure out the root cause behind the shift in appearance.

There are no scientifically proven methods to make nails grow faster
While poor health can slow nail growth, fast nail growth doesn’t necessarily mean good health. Your fingernails can say a lot about your health, and nutrient deficiencies may affect your nails' appearance. For example, changes in nail colour and growth patterns can signal health concerns.
You can also prevent nails from breaking by using nail hardeners, which are painted onto nails like a polish and are later removed with nail polish remover. Filing your nails can also keep them free of snags that may catch and cause splitting. To ensure your filing isn’t too harsh, it is recommended that you wet your nails first to soften the structure and make it pliable.
Biotin is an important type of B vitamin that allows the body to turn food into energy. Several human studies suggest that taking a biotin supplement daily can help strengthen nails. Some scientists say a dose of 2.5 milligrams of biotin daily can improve nail strength in just a few weeks.
