My probably "overly anlytical" two cents worth:
This "study" is not within the confines of the traditionally accepted scientific method. As was mentioned earlier, the "sampling" is not even statistically significant and the variances are too large. Furthermore, hair growth is only cell regeneration. If AA hair grows slower, then are we metabolizing and regenerating cells at a slower rate? It does not add up. All hair grows at approximately 0.5 inches/month. If not, there is a greater medical issue at the core of the issue. Our growth may grow in "tighter" and not seem to be in alignment with the standard growth, but there should not be any major variances. For example, has anyone gotten a relaxer on an inch of new growth, that turned out to be actually 2 inches of hair after the relaxer stretched it out? But the basis of hair growth is biochemistry, not race. Fundamentally, science has proven that race is just a myth used for political posturing and the like. Statistically, there is more variation within each race than between races.There are dominant and recessive genes, but there are not many scientific differences between races.
True...and well explained
