Which nail growth factor typically decreases with age?

Biotin is a vitamin that plays a crucial role in the growth and maintenance of healthy hair and nails. As individuals age, their bodies often experience a decrease in the production and absorption of various nutrients, including biotin. This decline can lead to slower nail growth and potentially affect the overall health of the nails, making them more prone to brittleness and breakage.

In the context of nail health, adequate levels of biotin are vital for promoting the strength and resilience of nails. When biotin levels are lower, one may observe changes such as slower growth rates and changes in texture or appearance. Hence, understanding the impact of aging on biotin levels helps in recognizing its importance in nail technology and overall nail care practices.
