exactly!
for people who are growing hair, dhumalla is a better option, when you tie a keski underneath, you take a support of turban material which help you in wrapping your small amount of hair and then tie your dhumalla on top of the keski. If you want I an probably help you with Dhumalla videos and or we can have a web acam session.
No offense but If highschool guys are wearing a patka ( it doesn't make it right). we should rather stick to our maryada and display a Khalsa image.
I know that you are a "Gora" Sikh .. For me a Sikh is a Sikh, I don't divide them in Gora/Kala/Neela/Peela

but yeah I got your point!
Trust me if you need a help, I can help you out for sure!
