Spectra is used to create a fully glossy section or a short area of contrast. Combining it with a matte material focuses the highlights exactly where you want them. Space out the wraps to maintain an airy body, or bring them closer together to create a denser texture. While applying, tuck the already-wrapped hair back toward the nape of the neck so it doesn’t get trapped under the next wrap. WSP strands are packaged in sets of four.
