why do my nails grow so fast

Your nails may grow fast due to several factors including genetics, overall health, nutrition, hormone levels, and the use of your dominant hand. Genetics largely determine your baseline nail growth rate, so if fast nail growth runs in your family, you might naturally have faster-growing nails. Good nutrition with sufficient protein, vitamins like biotin, and minerals such as zinc and iron supports nail growth. Hormonal changes, such as those during pregnancy or puberty, can also speed up nail growth. Additionally, nails on your dominant hand tend to grow faster because frequent use causes minor trauma, boosting blood flow and nutrient delivery to the nail area, which supports quicker growth. Warm weather and younger age also promote faster nail growth due to better circulation and metabolism. In essence, fast nail growth is influenced by a mix of genetic, physiological, and environmental factors that stimulate the nail matrix to produce new cells more rapidly.
