When to cut your sons hair

I have a 14th month old that was born with a lot of hair. I took him for a hair cut once and they really made it look bad. Me and my mom has trimmed it up but it is getting to the point where people are thinking he is a girl. I really need to get it shaped but me and my husband loves his hair and just want it shaped not cut short. I am not sure what we should do? Please leave me some comments and let me know what we should do.
