Use by itself or combine with BOLDIFY Hair Fibers for thinning hair for next-level coverage. Works great for grey coverage, rootline touchups, and brightening highlights, too!
  • 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?
