So have INope,
It is much much kinkier. I have observed both groups in large numbers.
Like I said Eritreans tend to have type 4 hair, but not 4c like West Africans. That’s why they typically have longer hair.
Somalis have type 3 hair. Typically type 3b-3c. That’s tightly-curled hair but not exactly kinky.
There are some Somalis with type 2 wavy hair but I have never seen a Somali with type 1 pin straight hair. There are also Somalis with type 4 kinky hair but I have never seen one with 4c hair.
