* Average Growth: Fingernails grow about 0.1 mm per day, which translates to about 3 to 4 mm per month.
* Toenails: Toenails grow slower, at about 0.5 mm per month.
* Factors Influencing Growth:
* Age: Growth is faster in children and young adults and slows down as we age.
* Health: Illnesses and nutritional deficiencies can slow down nail growth.
* Finger/Toe: The middle finger nails tend to grow the fastest, while the thumb nails grow the slowest.
* Other Factors: Pregnancy, certain medications, and even exposure to cold temperatures can also affect nail growth.
So, in short, it takes around 4 to 6 months for a fingernail to grow completely and about 12 months for a toenail.
