BL Lashes Black Diamond | Lash Sealant for Extensions — Extends Fills to 3-4 Weeks | Dark Mascara-Like Finish, Waterproof Coating, Brush Applicator (0.24 fl.oz)

• SHAKE WELL, THEN SEAL FOR LONGER-LASTING FILLS: Customers report extending fills from every 2 weeks to 3-4 weeks with consistent daily use. Apply one thin coat to completely dry lashes after every wash — waterproof protection against sweat, humidity, and daily wear. Shake the bottle for 10 seconds before every use.
• MASCARA-LIKE FINISH WITHOUT THE HASSLE: Dark tinted coating defines and aligns each lash extension for a fuller, polished look — even rogue lashes snap back into place. Delivers the volume of mascara with the protection of a professional sealant, without clumping or flaking.
• LASH TECHNICIANS CHOOSE IT TOO: Used and recommended by professional lash artists in their salons. One verified lash tech reviewer wrote: "My clients' retention is out of this world with this product" — professional-grade formula trusted for both salon application and daily home maintenance.
• GENTLE NOURISHMENT FOR NATURAL LASHES: Infused with Biotin, Panthenol, Allantoin, and Hyaluronic Acid — nourishing your natural lashes while keeping extensions in place. Intertek-certified with zero irritation in a 24-hour patch test. Apply to lashes only; avoid direct eye contact.
• RINSES CLEAN WITH WARM WATER — NO REMOVER NEEDED: Intertek-verified formula improves washability by 96%. Simply rinse with lukewarm water — no special remover, no residue, no fuss. The brush applicator is thin enough to reach every lash, making it easy to apply even half-asleep.
• HOW TO GET THE BEST RESULTS: Shake the bottle well for 10 seconds before every use — the pigment settles and shaking restores full color and consistency. Apply one thin coat to completely dry lashes only. Do not over-apply — a little goes a long way, and the bottle lasts longer than its size suggests.
• BUILT FOR ACTIVE LIFESTYLES: Gym, sauna, swimming pools — this sealant holds through sweat, humidity, and prolonged water exposure. Apply before your workout, and reapply after washing your lashes for continuous protection. Customers with oily skin also report significantly better retention.
• WORKS FOR EXTENSIONS AND CLUSTERS: Whether you get lash extensions at a salon or apply clusters at home, this sealant locks them in place. Customers who apply cluster lashes themselves report 2+ weeks of wear with regular use of this sealant as a final step.
• SMALL BOTTLE, MONTHS OF USE: A single 0.24 fl.oz bottle lasts months with daily use — because one thin coat is all you need. Customers consistently note it outlasts what the size suggests. Use it as your daily lash maintenance step and get the most out of every drop.
