There are men out there who have long hair. Thaliban brothers in Afganistan have long hair past their earlobes (actually I really like their culture there in Afganistan
), so do many Pakistani brothers, and I know this Pakistani brother (he's the "white" kind of Pakistani Muslim) in the UK who has Mashallah beautiful long hair past his earlobes and a good beard, and I know this one young uncle (he's thirty) at my masjid, and he's the white kind of Bangladeshi, and has curly long hair to his shoulders.
Mainly, men who have light skin or a lighter complexion are alright with keeping long hair, whilst those who don't, they don't really fit in good with the looks, but sometimes some brothers do, and they look fine.
Well my skin isn't really white, it's like orange to yellow tan to white, it has a bright look to it (well I'm actually talking about my face here, alot of my body is brown, except my face), so I'm thinking of keeping that "Afgani look" when I'm like 20+, long beard, Pagree, hiar past my earlobes, those Pakistani/Afganistani clothes, etc. kind of like what the Thaliban brothers look like.
