Linear viscoelastic measurements
All the oscillatory measurements were done at a constant frequency of 1 Hz. Figure S1 shows the frequency dependence of G’ and G” in the linear regime for three samples: Carbopol, emulsion and hair gel. These measurements were conducted at a later date than the
measurements in the body of the article. The linear moduli for Gillette Foamy were reported in an appendix to [Mora et al. (1991)].
