Understanding Fingernail Growth: Is a Variable Growth Rate Normal?

[lisab]

Is it normal that my fingernail growth rate is not constant?

Mine definitely grow in spurts. I keep them very, very short (about 1 or 2 mm), so it's easy for me to notice how the growth rate changes. About every 3 or 4 months, the rate speeds up dramatically.

I use a certain aftershave lotion that seems to rapidly increase my fingernail growth.
