Thank you! I think this speaks to the issues we have with ourselves as a people.
What's the big deal if our hair grows slower? As for those who point out taking vitamins, eating the optimal green diet and doing cardio 4x a time will grow faster, umm yeah, but how many people on the average do that.
Even if you control for those variables, black people's hair will most likely grow slower than our caucasian and asian counterpart.
This fact still doesn't mean you can't have MacherieAmour or Candy C's hair.
Yeah, it's not that big a deal, I don't think, if on average black folk's hair grows slower.
Anyway, I just read the full article. It's so short. I'm so used to being in the humanities, where articles are getting longer and longer. This was only 4 pages. It was interesting, though I'm not inclined to call it conclusive. It was not a long term study, but done just over 2 days. And it didn't say whether the study done on the white volunteers was done at the same time of year. I feel like our hair and nails, on average, grow faster at some times of years than others. They did not control for variables like exercise and diet, but they did say all volunteers were "healthy and free from any systemic or cutaneous disease."
They also made reference to some of their earlier unpublished work and also work done by others. They also found that, on average, africans have a lower density than caucasians (I think I read somewhere else that Asians have the lowest?), though the hair density varied among individuals greatly. Like, a lot. Like, some people had 3 times as many hairs on a given spot than some other people. Anyway, the general trend difference in scalp density between Africans and Caucasians was in line with two other studies they cited.
Men were more prone to alopecia (no surprise there).
Though the sample was too small to say anything definitively, the participants over 35 had a slower growth rate.
Let's see . . . hair growth rates did not differ significantly between men and women (I think it was the same for white people), but "women showed a higher hair density in the occipital region than men, and a lower one at the temporal site."
Ummm, what else . .. oh yes, "telogen" hairs. I take this to mean hairs in the telogen, i.e. non-growing, phase. On average, men had more hairs in this phase than women, and Africans had more hairs in this phase than Caucasians.
Then there was a note on "global hair volume," where I didn't fully understand what the numbers referred to, so I'll just copy and paste:
As far as global hair `volume' is concerned, an index
may be estimated by multiplying hair density by the
rate of hair growth, integrating both factors. Such an
index would lead to a nearly twofold difference in hair
`volume' between the two populations, for both sexes
(53,040 vs. 96,471 in Africans and caucasians,
respectively, based on data found on the vertex).
However, this crude and theoretical index does not
take into account additional factors such as curliness,
which plays a great part in the visual perception of
global hair `volume'.
Okay, make of it what you will. If you are able to read it for yourself and want it, it's by Loussouarn, 2001, the British Journal of Dermatology, Vol. 145 issue 2.
