A 'money piece' is the bright, face-framing section right at the front of your hair — the highlight that does the most work. It can be subtle (a single shade lighter than your base) or dramatic (platinum against dark brunette).
Most stylists charge an extra $50–80 on top of base color for the money piece. This app lets you A/B subtle vs dramatic on your own selfie before you spend it.
Pick a shade, try a width, screenshot the winner, take it to your appointment.
