🔧 A three-pack of UV-cure extension adhesive built for specialists running high-volume schedules — the kind of supply depth that keeps your service flowing without mid-week restock scrambles.

The UV-curing photopolymer system stays fully workable until you activate the lamp, giving you precise placement control before the bond locks. That on-demand cure window means fewer repositioning errors and less adhesive waste per set. Post-cure, the bond remains pliable along the hair shaft rather than rigid — so extensions move naturally and stress on the attachment point stays low throughout the wear period. The clear finish disappears against any hair color, keeping bond points invisible at the scalp.

Three units per purchase supports multiple full-head sets or an extended run of partials between orders — practical inventory logic for any specialist who tracks cost-in-use seriously. Note: clean removal depends on the matched Cosimo Luma removal system; confirm availability before booking removal appointments.

Worth stocking for extension specialists who need consistent bond performance across back-to-back client days.

• Controlled Application Window: UV-cure chemistry stays workable until the stylist activates the lamp, giving precise control over placement before locking the bond — reducing waste and repositioning errors during the service.
• Invisible Bond Point: The clear cure finish conceals the attachment area against all natural hair colors, supporting a seamless finish that clients expect from professional extension services.
• Natural Movement and Feel: The flexible post-cure bond moves with the hair shaft rather than creating a stiff attachment point, allowing extensions to feel and behave like natural hair during wear.
• High-Volume Service Efficiency: Three 20g bottles in a single purchase provides sufficient adhesive volume for multiple full extension sets or an extended run of partial applications without mid-service restock interruptions.

UV-Curing Photopolymer System: The core adhesive chemistry that transitions from a fluid state to a solid polymer bond upon exposure to UV light. This cure mechanism allows the stylist precise control over working time — the adhesive remains workable until the UV lamp is applied, then locks instantly into a durable, flexible bond.

Clear Optical Formulation: The adhesive cures to a transparent finish, making the bond point virtually invisible at the scalp and allowing seamless blending with all natural hair colors without visible residue at the attachment point.

Flexible-Cure Bond Chemistry: Formulated to remain pliable after curing rather than setting into a rigid bond, allowing the attachment point to move naturally with the hair during wear and reducing the stress concentration that can cause premature extension slippage or hair breakage at the bond site.

1. Prepare the client's natural hair by ensuring it is clean, completely dry, and free of oils, conditioners, or styling product residue at the attachment zones — any surface contamination will reduce bond strength.
2. Section the hair according to the planned extension placement map. Work in small, consistent sections suited to the extension method being used.
3. Dispense a small, controlled amount of Cosimo Luma Adhesive directly onto the extension bond point or into the bond area, using the bottle tip for precise placement.
4. Immediately position the prepared extension section against the natural hair at the intended attachment point, pressing firmly to ensure full contact between the adhesive and the hair.
5. Apply the UV lamp directly to the bond point and hold until the adhesive is fully cured and the bond is solid. Follow the Cosimo Luma UV lamp specifications for distance and cure time.
6. Check the bond for firmness before moving to the next section. A fully cured bond should be rigid at the attachment point and flexible with natural hair movement along the shaft.
7. Repeat the dispense–position–cure sequence for each extension section, recapping the bottle between placements to protect unused adhesive from ambient light exposure.
8. At service completion, inspect all bond points for complete cure and secure attachment before releasing the client.

Service and Retail Efficiency

The 3-bottle pack is sized for high-volume salons and extension specialists performing multiple full-head sets between orders. Track adhesive usage per service to forecast restock timing accurately — UV-cure adhesives can degrade if stored after opening for extended periods. For removal services, confirm availability of the compatible Cosimo Luma removal product before booking; the brand specifies that clean removal is contingent on using the matched system.
