On which finger does nail growth typically occur at a slower rate?

Nail growth rates can vary among different fingers due to factors such as blood circulation, region of the finger, and the natural movement each finger experiences. The thumb generally has a slower nail growth rate compared to the other fingers. This is often attributed to its use and functionality, which is not as consistently engaged as the other fingers during repetitive tasks.

Blood supply may also be more concentrated in the index and middle fingers as they are often used more actively, leading to more rapid growth in those areas. In contrast, the thumb, despite being crucial for grip and dexterity, may have slower growth due to its unique positioning and how it is utilized in everyday tasks. This physiological aspect is important for understanding nail health and growth patterns within the field of cosmetology.
