One of the main reasons people return hair fibers is simply because they haven’t mastered the application technique. Hair fibers are a “buildable” product—a little goes a long way, and the right method makes the difference between a patchy look and a full head of hair.

Follow this step-by-step guide to get professional results on your first try and ensure your Finally Hair Fibers stay locked in all day.

Step 1: Start with Dry, Styled Hair

Hair fibers rely on static electricity to cling to your hair shafts. If your hair is damp or oily, the fibers will clump together.

The Pro Tip: Wash and dry your hair completely. Apply any styling products (gels or pomades) before adding fibers. Let the styling products dry before proceeding.

Step 2: The “Sprinkle and Pat” Technique

Don’t rush this part. Aim for the “less is more” approach.

The Sprinkle: Hold the Shaker Bottle 2-3 inches above the thinning area. Tilt it at a 45-degree angle and gently shake it over the area.
The Pat: After a few shakes, use your hand to gently pat the fibers down. This helps the fibers settle further down the hair shaft and prevents them from sitting loosely on top.
Repeat: Build up the density in layers until the scalp is no longer visible.

Step 3: Mastering the Hairline

Applying fibers to the forehead area is where most beginners struggle. You want to avoid a “straight line” look.

Use a Shield: Use the Finally Hair Hairline Optimizer or a simple business card to shield your forehead.
The Edge: Place the optimizer against your forehead and sprinkle lightly behind it. This creates a soft, natural, irregular hairline that looks like real growth.

Step 4: Lock It in (Essential for Success)

If you skip this step, the fibers may shift during the day or come off on your pillow.

The Spray: Once you are happy with the look, apply a light mist of Finally Hair Fiber Lock Spray.
Why it Matters: This specialized spray increases the bond between the fibers and your hair, making the look wind and sweat-resistant.

Common Beginner Mistakes (And How to Fix Them)

Problem	Likely Cause	Quick Fix
Visible Clumps	Applied to wet hair or used too much at once.	Use the “Pat” method and apply in thin layers on dry hair.
Fibers on Forehead	Shaking too close to the face without a shield.	Use the Hairline Optimizer for a clean edge.
Color Looks Off	Choosing a color based on your roots instead of the ends.	Match the color to the hair that will be covered by the fibers.
Fibers Rubbing Off	Skipping the locking spray.	Always use Fiber Lock Spray to set the look.
