  • 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!
  • Easy to apply, mishap-free fibers that outlast the day: Wash, fully dry, and style hair as usual. Shake fibers over desired areas and pat gently to set in place for a noticeably thicker look, instant scalp coverage, and a fuller finish that lasts all day. Set with the spray of your choice to maximize weather and sweat resistance; easily and cleanly remove in a single shampoo.

INDUSTRY-LEADING COLOR MATCH

Made from all-natural plant-based fibers that bond undetectably to existing hair.

Tips & Tricks

Between 2 shades?

Go darker! Always aim to match the hair at the ROOT.

NEVER use the mid-lengths and ends to color match Fibers.

Does the finish look powdery?

Try using less product per application.

Are the fibers noticeable?

Try the next shade darker.

Not getting desired coverage?

Try combining with Hairline Powder as a base!

What do Hair Thickening Fibers do?

They provide instant coverage for bald patches, thinning areas, and wide parts. With a unique sheen for a real-hair effect, our wind/water/sweat-resistant Fibers provide the undetectable coverage you need to regain your confidence and live boldly!

Is this for men or women?

If you have hair, Boldify Fibers are for you...gender is inconsequential!

What’s the difference between Hair Fibers and Hairline Powder?

Hair Fibers are best for those with some hair, while Hairline Powder provides coverage for little to no hair. Fibers are applied with a shake-top bottle and Powder is dabbed on for more precise application. Many customers choose to use both!

What if my hair color is between 2 available shades?

We generally recommend going with the darker of the 2 colors for maximum coverage, as hair is typically darker at the roots. However, mixing/layering 2 different Fiber Colors is also a great way to create a custom color to suit your individuality!

What are the ingredients?

Unlike other brands, BOLDIFY Hair Fibers are all-natural and contain just three safe ingredients. Gossypium Herbaceum (Cotton), Mineral-based colorants (Natural Iron Oxides), Sodium Chloride (Salt)
