BOLDIFY Hair Fibers (28g) Fill In Fine and Thinning Hair for an Instantly Thicker & Fuller Look - Best Value & Superior Formula -14 Shades for Women & Men - DARK BROWN

Clump-proof fibers for a real hair effect & undetectable finish: Boldify Hair Thickening Fibers are the premium solution to instantly disguise thinning and patchiness at the crown and along the partline. Our advanced hair powder fibers boast follicle-mimicking molecules that allow seamless blending and a natural, real-hair finish. For best results, at least some hair must be present. Looking for more coverage for areas with less hair? Boldify Hairline Powder may be a better fit!
The Right Shade, Guaranteed: When selecting one of the 14 available shades, always seek to match your hair at the roots; matching the midlengths/ends is the number one color match issue we see. If you think you're between 2 shades, always go with the darker option -- it'll look the most natural! Fibers that are too light will always create an undesireable finish. Need help? Pick the wrong color? Don't contact Amazon! Click "Contact Seller" so that our dedicated Customer Care Team can assist!
Superior products made better: Our natural, Cruelty-Free Hair Building Fibers are made under strict quality standards in our ISO 9001 facility. We responsibly and sustainably source only the finest ingredients to create a superior - yet affordable - product that works far better than other overpriced keratin fibers!
Hassle Free Satisfaction Guarantee: We’re so sure that you’ll regain your confidence and adore your results that we back each bottle with our comprehensive risk-free guarantee. Buy and try a bottle of Boldify Fibers and love it - or we’ll refund the purchase price upon request. Period. No hassle, no questions asked, no return required!
