Swelling of hair fibers at room temperature. Fibers from a Caucasian male were incubated in water or 0.1 M sodium phosphate (pH 7.8), in the latter case with 20 mM DTE and/or 2% SDS. Samples were examined after 6 hr except as indicated (2 hr). Shown are the means and standard deviations of diameters of 6–30 fibers for each condition measured microscopically (16×) using Slidebook 5.0 software. Swelling and increased flexibility are first noticeable visually after 1–2 hr, at which time hair fibers can be fixed and embedded.
