💇 A UV-curing extension adhesive set in black — built for dark-hair clients where bond visibility at the grow-out line is the difference between a seamless result and a service callback.

The UV-curing formula locks each bond point quickly under a lamp, keeping chair time tight across multi-placement services. Once cured, the adhesive stays pliable rather than rigid, so the attachment zone moves naturally with the hair and clients don't feel a hard anchor at the root. The black pigment is matched for dark brown to black hair, concealing the bond as extensions migrate with natural growth — no dark dots surfacing through lighter regrowth zones.

Stocking a dedicated black-colorway adhesive alongside the clear variant means every client gets a color-matched bond without mid-service workarounds. This set supports that dual-colorway inventory at a practical supply depth for active extension practices.

For salons running consistent extension bookings where bond discretion and efficient cure time are non-negotiable.

• Strong, Reliable Extension Bond: UV-curing chemistry forms a secure bond at the attachment point, helping extensions stay in place through daily wear.
• Lightweight, Flexible Hold: The cured adhesive remains pliable rather than rigid, allowing the attachment zone to move naturally with the hair and reducing the feel of extensions at the root area.
• Rapid UV Cure: Activates quickly under UV light, reducing chair time per application point and supporting efficient multi-placement services.
• Black Colorway for Blending Precision: The black-pigmented formula blends visually at the bond point for clients with dark hair, concealing the adhesive joint for a more seamless result.
• Natural Grow-Out Behavior: The bond is designed to migrate naturally as the hair grows, maintaining wearability over the extension lifecycle without creating a fixed, rigid anchor point.

1. Prepare the client's natural hair by ensuring the application zone is clean, dry, and free of oils or product buildup. Section hair as required for the placement pattern.
2. Dispense a small, controlled amount of Cosimo Luma Hair Extensions Adhesive (Black) onto the extension attachment point or bond tip. Avoid overloading — excess adhesive increases bond bulk and complicates removal.
3. Position the extension strand or weft at the desired attachment site against the natural hair section.
4. Expose the adhesive to a UV lamp at close range. Hold until the bond is fully cured and no longer tacky. Cure time will vary by lamp output — follow the UV lamp manufacturer's recommended exposure distance and duration.
5. Repeat the application and curing process for each extension placement, working section by section.
6. After the service, advise the client on wear care appropriate for bonded extensions. For removal, use only the Cosimo Luma system-matched removal products and process.

Matching Bond Color to Client Hair

Use Black adhesive for clients with dark brown to black hair to minimize bond visibility at the root zone as extensions grow out. For clients with lighter hair — blonde, gray, or highlighted — switch to the Clear variant to avoid visible dark bond points. Keeping both colorways in stock allows seamless client matching without service delays.
