Table 1.
Microscale surface texture parameters in pristine and halloysite-treated hair, coated with halloysite (HNT). Sq (root mean square height if roughness); Sz (maximum roughness height); Ssk (Skewness); Sku (kurtosis-deviation from Gauss distribution; Sal (autocorrelation length); Str (texture aspect ratio); Sdr (developed interfacial area ratio).
