My DS has curls as well, not masses of them but really cute ones at the end. I had also put off taking him to the hairdressers for well after he needed to get his hair cut for that very reason - I was afraid his curls would go! But they didn't - he still has them but now hair looks lot nicer and less surf bum look (which is quite an achievement for a 2 year old). Only thing that I did do was to make sure I took him to a place where they cut kids hair the whole time that way I felt they would know how I'd feel with him getting his hair cut for the first time and how important super cute curls are to a Mommy
