I have been wearing NOTHING
I have been wearing NOTHING but BFB extensions (the UP, the FILL-INS, the CLASSIC, the heavy weight FILL-INS) the latex clip-ins ,are genius for those of us with thin hair, lay flat against the head. If not , you can always use flatiron (on low heat) to flatten out the clip-in area. I love these. I have had mine for years. Treated like a fine car, they will last forever. Treat them carefully -oil treat them- hang on hangers and the quality speaks for itself. LOVE LOVE LOVE!! I’m never using any other hair.
