pure NV BKT Humidity Defense Hair Spray (non-aerosol) is a keratin infused, lightweight, non-flaking hair spray with a flexible hold for damp or dry hair styling. pure NV BKT Humidity Defense Styling Spray, with its soothing aroma, is perfect for a beach wave textured effect on damp hair or for volume, shine and hold on dry hair. BKT Humidity Defense Styling Spray is unique to other hair sprays. Conventional hair spray fibers are either long and straight or short and straight. When long, straight fibers are overlapped in a mesh pattern they create a strong hold, and when short straight fibers are overlapped in a mesh pattern they create a light hold. BKT Humidity Defense Styling Spray is uniquely formulated in that the fibers are OVAL shaped and small, which leaves little room in between them, blocking humidity out of the hair. This technology allows for a light hold when sprayed sparingly or a more firm hold when sprayed more heavily. BKT Humidity Defense Styling Spray is beneficial for all hair types, whether or not a pure NV BKT service has been applied. When used after a pure NV BKT service, pure NV BKT Humidity Defense Styling Spray will hep rolong its duration.
