Good day Dr.Rassman and company. Here is a picture of professional hockey player Ryan Getzlaf back in 2003 when he had gotten drafted to the Anaheim Ducks.
How did he lose hair so fast?
According to Google, Ryan Getzlaf is 27 years old now… so he was a teenager in that first photo from 2003 and his juvenile hairline is clearly evident. In young men (under 35 years old) hair loss is not a steady process, as it may come in spurts. Hair loss over an 8-9 year time frame is not fast from a genetic point of view.
