Maximum volume, maximum length, one price. The HEC Hair 4-Bundle Deal adds a fourth weft for clients who need extra fullness — thicker hair, longer lengths, or both — and want the install to look genuinely, undeniably full from every angle. Four bundles of 100% Remy human hair in your chosen length and shade, matched for texture and density. The go-to package for longer installs where three bundles would leave the ends looking thin, or for clients who want that thick, camera-ready volume that turns heads. Available in 6 lengths from 14" to 24" across all 7 shades. Add an HEC Hair closure to complete the install. Not sure which shade is right for you?
