Our 12” fill in hair extensions are discreet clip-in wefts designed to add targeted fullness around the front, sides and temples where hair is often finer or shorter. The flat root-mimic base, with hair individually placed into the band, sits flush to the scalp for a seamless, invisible blend with no glue or bonds. The 12” length is ideal for subtle enhancement on shorter styles or where a natural finish is key. Thin hair types typically need 1–2 packs, while medium to thick hair types may prefer 3–4 packs.
