What’s the chances of one of them being on this site they’re probably less than 0.5% of all somalis
They're honestly not as uncommon as one might think. I have at least 2-3 in my close extended family and at the local largest masjid in Boston that is quite dominated by Somalis I'd say at least 1 in 10 or so of the adeers I see there have that hair-type. But they are definitely a minority. The majority of Somalis and indeed all Horners have some variation of curly hair, some have true afro-textured hair (more common among Highlanders) but yeah, some do have straight to wavy hair.
