Nanogen Hair Locking Spray
STEP 1 - Apply your Keratin Hair Fibres as normal.
STEP 2 - For a secure hold, hold the bottle 10cm from your hair and spray four times.
STEP 3 - For maximum water resistance, hold the bottle 5cm away and spray eight times ('double sprays').
STEP 4 - If your hair gets wet, allow it to air dry without touching it, then reapply Locking Spray as required.
*In clinical tests using 'double sprays', 90% of Fibres remained in place after five minutes immersion in water.
