How Long Can Vellus Hairs Get?

Hey Doctor

My question is a brief one, in regards to Vellus hairs, how long can they grow?

Occasionally i will find that a hair has fallen out that is quite abit shorter than the rest on my hair, and alot thinner. For example my hair is 5 inches long, and the smaller thinner hair that falls out is 2 inches long. Is this a vellus hair?

Thanks

Vellus hairs are present in every follicular unit (one or two of them), and I believe they are defined as the peach-fuzz like hair usually 2mm or less in length. So if you’re seeing a 2″ long hair falling out, it’s not going to be a vellus hair.
