KUURL — Curly Hair Product Finder Platform
Hamid Sabri / April 21, 2026
People following the Curly Girl (CG) method face a frustrating problem: finding products that are silicone-free, sulfate-free, cruelty-free, and actually available where they live. The r/curlyhair community had been maintaining a massive spreadsheet to track this — functional, but not user-friendly, not searchable, and not localized.
I built KUURL to turn that raw community data into a fast, clean, searchable product discovery platform — available in English and French, with country-level availability filters.
The Problem
Curly hair care is a rabbit hole. Between decoding ingredient lists, cross-referencing cruelty-free certifications (PETA, Leaping Bunny, Choose Cruelty-Free, Vegan), and figuring out what's even sold in your country — it can take hours to vet a single product.
The community knowledge existed. It just wasn't accessible.
What I Built
KUURL is a full-stack web platform with three core pillars:
1. Smart Product Finder
Users filter by country (France, Germany, Morocco, Spain, United States — more being added), product type, and CG approval status. Results show certification badges and direct purchase links — online or local. Try it →
2. Community Submissions
Anyone can submit a new product in seconds. This keeps the database growing without relying on a single curator.
3. Bilingual Support (EN/FR)
Built with French and English-speaking curly communities in mind from day one — not an afterthought.
Key Features
- CG Approval Status — Approved, Unclear, or Not Approved labels on every product
- Cruelty-Free Badges — PETA, Leaping Bunny, CFK, and Vegan certifications surfaced clearly
- Country Filter — Only shows products you can actually buy where you are
- Direct Buy Links — No dead ends; links go straight to retailers
- Product Submission Flow — Authenticated users can contribute new products
- Guides — Educational content for people new to the CG method
- Responsive Design — Works seamlessly on mobile, where most users land
Architecture
The platform is built around a structured product database with a filtering layer on top. The data originated from the International CG List compiled by the r/curlyhair community, which I cleaned, normalized, and loaded into a scalable schema.
The frontend handles filtering client-side for speed, with server-side rendering for SEO and initial load performance. User authentication gates the product submission flow to reduce spam while keeping contributions open to the community.
Design Decisions
A few intentional choices that shaped the product:
- Country-first filtering — Most existing CG tools are US-centric. Leading with country selection makes the experience immediately relevant to the user.
- Status over perfection — Rather than only showing "Approved" products, surfacing "Unclear" items gives users the full picture and mirrors how the community actually talks about products.
- Low-friction contributions — The submit flow is deliberately short. More friction = fewer submissions = a stale database.
Outcomes
- A searchable, filterable database replacing a hard-to-navigate community spreadsheet
- Multi-country support making CG-friendly shopping accessible beyond the US market
- A self-sustaining contribution model that keeps the database growing over time
- Bilingual reach across English and French-speaking curly communities
