Is my hair growinf ridiculously fast?

Most of my family's hair grows at most a few inches a year, but for me, it grows muh faster. I recently donated my hair and it brushed my collarbone in a picture I took no more than 5 weeks ago, and now it's over an inch longer. I tend to have lots of natural fats and oil in my diet, my family has salmon and avocado on salads a few times a week. Does this influence my hair growth? It does nothing for my mother or siblings.
