How do I apply Fibolica? For best results, your hair should be clean and dry. Hold the bottle at a 45 degree angle 2-3 inches above the thinning area. Gently shake or tap small amounts of the hair fibers over the thinning area starting from the back of the head and work your way up towards the front. Slowly build up to a more natural coverage by repeating the application a few times till desired result. Lightly brush or pat the fibers to blend them in with your natural hair. For added control, apply a light coating of hair spray to lock fibers in place (optional). Click here to see detailed application instructions.
