Product Requirements Document

Original Business Idea

I'm a hairstylist who wants to remember each client's preferences. I want 'StyleNotes' - an app to save client photos, colors used, and next appointment notes.

StyleNotes is a lightweight client memory app for hairstylists to store photos, formulas/colors used, cut and style preferences, and next-appointment notes in one searchable place. It helps stylists deliver more personalized, consistent service, reduce repeat questions, and build stronger client loyalty across every appointment.

Business Goals

Increase stylist weekly active usage by 35% within 6 months through repeat appointment workflows and fast note capture.

Improve client retention by 10% for independent stylists and small salons that use StyleNotes to personalize follow-up visits.

Drive a 20% conversion rate from free trial to paid subscription by proving value after the first 3 client profiles are created.

Position StyleNotes as the category-leading client memory tool for beauty professionals by capturing product usage, photos, and appointment history in one app.

User Goals

Quickly recall each client’s haircut, color formulas, and style preferences without relying on memory alone.

Capture appointment notes in under 30 seconds after a service so nothing important is forgotten before the next visit.

Store and compare before/after photos to communicate results and track style evolution over time.

Prepare for upcoming appointments with clear reminders about client preferences, allergies, and goals.

Build stronger client trust by consistently remembering details that make each visit feel personalized.

Non-Goals

StyleNotes will not be a full salon POS, payment processing, or inventory management system.

StyleNotes will not replace professional image editing or advanced photo retouching tools.

StyleNotes will not include public social networking or client-facing profile sharing as a core feature.

StyleNotes will not provide automated hair color formulation recommendations based on chemistry or AI diagnosis in v1.

Ava runs a busy independent salon booth and sees the same clients every few weeks, but the details start to blur after long days. One client asks for the same blonde tone as last time, but Ava has to dig through texts and scattered photos to remember the formula. With StyleNotes, she logs the service in under a minute, adds the toner mix, snaps a before-and-after photo, and sets a reminder for the client’s next maintenance visit. A few weeks later, the client returns and Ava opens the profile in seconds. She immediately sees the previous color formula, the styling notes, and the reminder about avoiding warm tones. The client feels remembered and cared for, Ava saves time, and the appointment starts with confidence instead of guesswork. Over time, that consistency helps Ava build trust, improve rebooking, and turn great service into a stronger business.

Team sharing creates privacy complexity, so permissions must be simple but strict enough to prevent accidental exposure.

Search quality must remain strong even with messy, incomplete, or duplicate client records.

Monetization can be challenging if stylists expect a low-cost tool, so premium value must be tied to clear productivity gains.
