Will it work for my hair and look natural?

It works best where some hair is still present, including the crown, temples, hairline and patchy beard areas. Straight, wavy, curly and coily hair can all benefit from carefully blended coverage.

Completely smooth bald areas: results are more limited because there is less hair for the powder to blend with. It conceals thinning; it does not regrow hair.

Choose a close shade match, apply lightly and blend the edges. The result should look like your hair, just fuller.

  • Buildable coverage
  • Natural-looking finish
  • Targeted application
  • Shampoos out
How do I pick the right shade?

Choose the shade closest to the hair around the area you want to fill. If you are between two shades, choose the darker option and apply lightly.

Use Find your shade above the shade selector for help. If your first order is too light or too dark, contact us within 30 days of delivery for help under our Shade Swap Guarantee.

How do I apply it?
  1. Start dry

    Style your hair first. Open the jar and take out the puff applicator.

  2. Load a little

    Pick up a small amount of powder with the puff.

  3. Dab and blend

    Gently dab onto thinning spots. Build coverage gradually and soften the edges.

  4. Let it set

    Allow 3 minutes before touching the area. Check the result in the mirror.

Tip: Start with less than you think you need. You can always add more.

Will it stay in place, and how do I remove it?

The powder is designed to resist everyday sweat and rain. Let it set after application, and avoid rubbing the area, especially when wet. Wear can vary with the amount applied and your routine.

Wash it out with your regular shampoo when you are ready to remove it.
