When a man’s forelock hangs in while everything around it has hair loss, you should recognize its value for properly styling a good hairline. These forelocks, if they remain after the age of 35, will usually stay for life if they are strong at 35. His balding pattern relates to the area of balding, ignoring his forelock, making it a Class 3A pattern with a persistent forelock. The arrows show the balding around the forelock. If this man is young (18-25), he has a good chance of reversing this with appropriate medications like oral finasteride and oral minoxidil.
