What should I say to my barber if I want a no-fade hair cut (Just those scissors layers) ?

I've been growing my hair for 3 months now it's like 3 and a bit inches on yhe top and less than one inch on the sides I am trying to get a flow haircut so I was thinking of a maintenance cut because it's unpresentable now How to ask my barber for such thing? What to say exactly (Something like Charles Leclerc's hairstyle)
