I think i should get a trim every 1 or 2 weeks to grow longer hair. what do you think?

im a 17 year old boy, and my hair is just like 1/2 inch shorter than zach efron's hair. so yeah, it's that long. i got a trim 2 weeks ago just taking 1/2 inch off and in a week my hair has grown like 1/2 inch, but then it would grow very very slowly after that. Would it be a good idea to trim it like 1/8 of an inch every week or two weeks to have it longer in a faster time? would the hairstylist think i'm weird for only wanting 1/8 inch off?
