Step-by-Step Guide:

1. Brush your brows: Start by brushing your eyebrow hairs upwards and outwards with the spoolie to see your brow's natural shape and identify areas that need filling. 
2. Create hair-like strokes: Using a light hand, draw short, flicking strokes that mimic natural eyebrow hairs. Follow the direction of your natural hair growth. 
   • For the front of the brow, flick upwards and slightly curve the top. 
   • For the middle section, use downward strokes as hairs tend to grow down at an angle. 
   • For the sparse outer corner, use very light-handed strokes. 
3. Fill in sparse areas: Focus on the areas that look the most sparse to build your brow's fullness. 
4. Blend with the spoolie: Use the spoolie to gently comb through the pencil strokes. This will soften any sharp lines and blend the product into your natural brow for a more diffused and natural look. 
5. Repeat on the other brow: Follow the same steps for the other eyebrow to create a balanced look.
