BOLDIFY Hairline Powder - Root Touch Up Hair Color for Gray Coverage - Bald Spot Concealing Hair Powder for Women & Men - 48-Hour Stain-Proof - Light Brown
Why we love it
Long-lasting coverage up to 48 hours.
Compact and easy to carry.
Precise, mess-free application.
Main highlights- The Ultimate Hair Root Touch Up, No Sticky, Gunky Feel: While root cover up spray (hair color spray) can be messy to apply and leave your hair feeling greasy, gunked up, and...gross, BOLDIFY Hairline Powder glides on smoothly, providing undetectable highlights and grey hair cover up for Women and Men - without the fake feel. An exceptional Root Touchup Spray Alternative for extending the time between salon visits, and more precise than the average hair fiber for easier hairline coverage.
- The Right Shade: For scalp coverage, you'll want to match your root. For color touchups and grey coverage, always match the strand where coverage will be applied. For freshening highlights, matching the ends is usually best. Between 2 shades? Go with the darker option at the root, or the lighter shade for highlights -- it'll look the most natural! Need help? Pick the wrong color? Don't contact Amazon! Click "Contact Seller" so that our dedicated Customer Care Team can assist!
- The BOLDIFY Promise - Supercharge Your Hair & Happiness with BOLDIFY hairline powder.

- Easiest To Use: Unlike other hair toppers for women, hair fibers for thinning hair for women, and hair thickening products for women, Boldify Hairline Powder makes it easy to cover thinning, root re-growth, balding and/or patchiness. The Compact mirrored travel kit design is ‘style change ready,’ Simply remove the base, dab it onto the applicator, and get the ultimate coverage and confidence, wherever you happen to be!
