Hair Extenions Please help!!

Hi girls,

Was hoping someone on here may be able to recommend me an extensionist in Scotland?! I am in Glasgow :)

Also as my hair is sooo think i usually get it razored a bit to take some of the bulk out, i am due a cut and was wondering if i should get it razored before going for my extensions, would this cause the extensionist any problems, would i be best leaving it??

Also as my hair is so thick i am worried about what look i will get with extensions as i would hate just to have a mass of hair

One more question (sorry)!.. I currently have brown hair with some golden blonde highlights but as my hair is naturally quite dark i was thinking about getting an all over brown before my extensions as i don't know what would happen with needing to get my roots done??!

Any help would be much appreciated.
