Lock In Your Look — All Day, Whatever The Weather
Formulated to work in perfect harmony with Hair Guru London Hair Thickening Fibres, this Locking Spray creates a fine, invisible bond between the fibres and your natural hair. The micro-mist secures your style without stiffness or sticky residue, leaving your hair feeling completely natural — just locked in place.
All-Day Protection
Once dry, the spray forms a waterproof, wind-resistant shield that keeps your density looking natural from morning to night. Holds through rain, sweat, and wind without any crunchy or stiff feeling. Stays put until you wash it out with regular shampoo.
The fine-mist nozzle delivers more even coverage than a standard spray, so you get consistent hold across the entire area without oversaturating any one spot. Ideal for daily use and compact enough to carry for touch-ups throughout the day.
Perfect Pairing
For the most natural, long-lasting result, use alongside Hair Guru London Hair Thickening Fibres 28g and the Easy Apply Fibre Pump. The pump delivers precise fibre placement; the locking spray seals everything in place.
