Hair Ethnicity 214 integrity. Results showed that the propensity of breakage was higher for hair that was identified as being Afro compared to Caucasian. Internal studies on the effect of ethnicity have been expanded to include more ethnic groups where curl classifications have been determined. The ethnic groups and distribution of curl from one study are seen in Table 4. Results located in Figure 9 revealed that the strength in hair increases in this manner: Kenyan Liberian = Ghanaian Jamaican = African American Brazilian Caucasian American.

Caucasian American and Kenyan hair had the smallest cross- sectional areas and that from Jamaica had the highest. Brazilian, African American, Ghanaian and Liberian hair were statistically the same (Figure 10). Results from ellipticity values were as expected based on common knowledge. Caucasian hair was the least elliptical followed by Brazilian hair. All hair from African descent were the most elliptical (Figure 11). From the study above, the same data was used to observe changes in physical properties as a function of curl. Curl types II through
