Color Lab (Colour Lab in the UK) is a tablet app with a Bluetooth scale for hair salons and independent colorists. Stylists scan the tube's barcode with the tablet camera: Color Lab recognizes over 30,000 professional products from every brand, so nobody types product names. They squeeze the color onto the scale and the grams save to the client's record, so anyone in the salon can repeat the same formula to 0.1 g. If a mix runs short, even by 15 g, Color Lab recalculates every product so the top-up keeps the exact proportions of the original mix; last visit's formula can be repeated in any amount the same way. It also works out the developer for the chosen ratio and weighs the leftover in the bowl so the next mix is smaller. It shows the cost of every color service and usage statistics by product and stylist. The Salon Manager plan adds stock levels, supplier orders by email, deliveries and stocktakes: scan products during opening hours and weigh opened tubes on the scale. Keeps working when the Wi-Fi drops. Used in Poland since 2020 by nearly 100 salons. Prices per location per month, excluding VAT or sales tax: Simple £49 / $65 / €55, Pro £65 / $85 / €75, Salon Manager £99 / $129 / €115. The barcode scanner add-on is free for salons that start in 2026.
