I hope all is well today. I was curious as to why hair around ones ear and lower hairline (the rim around sideburns/ ears to bottom back part of head / even up to temples) only grows a certain length. I guess I just assumed this hair would keep growing for years and be as long as ones hair on top. I am not experiencing MPB or anything, I was just curious. Seems as though even no matter how long my hair on top and mid sides gets these hairs around the hairline perimeter only grow so long, maybe just a few inches.
Hair that grows in different parts of the scalp and neck vary from each other based upon your genetic programming. We are all different, so what applies to one person may not apply to another. For example, neck hair does not grow long like scalp hair in most people and it may even be different in texture.
