Hi there,
does anybody know a good software for Hairstyle simulation where I could import my pic and create the style I want just on the monitor ?
They exist but those, that I found so far contain only womens haircuts and the "view mode" is allways frontal what makes it boring...
Those simulators never look good. They just look like they slapped a wig on the woman's head. They aren't very effective for figuring out a good style.
Your best bet is to figure out your face shape, your side and temple recessions, and the style you want and go from there.
