can you dye hair extensions or will the dye not work under the bonds?

[deedee24]

i have light blonde hair and want to dye it brown, i have indian hair extensions in and would love to dye my hair dark brown for the reminder of my extension period, i've had them in for a month and will be taking them out in 2 mths... my questions is, if i dye my hair at a proper salon, will the dye take to my hair or when i get my extensions out will i be left with loads of blonde marks on my hair where the dye didn't reach underneath the bond???? Does anyone know??? much app x
