You don't need new blood though you just need to find a somali male with no bidaar and large forehead and let him create as many babies as possible and let those with bidaar not have any kids, if you want to use the radical way.That I already mentioned many times. https://www.somalispot.com/threads/receding-hairline.69080/page-3
You are obviously new. I am not radical I am honest man. It's also partially due to genetics.
