Right I went to the college today and think I get this which i think has been explained here but let me try explain and see if I am right...
A VRQ diploma and an NVQ is the same course in terms of things you learn the only difference is..
VRQ diploma is a college based course, you do all your learning in college and maybe a college salon, models and sometimes a 5 day work experience in a salon.
NVQs are work based, so you need to be employed in a salon as an apprentice, u work so many days in the salon and u go to college 1 or 2 days a week for learning.
An NVQ level 2 and VRQ level 2 diploma are the same qualification, u could do 1 of them on level 2 and qualify for a level 3 on the other.
VTCT is the name of the awarding body, like city and guilds or OCR.
Both qualifications are recognised (NVQ and VRQ diploma). NVQs are meant to be better as you have more salon experience.
Hope that is right otherwise I am confused! Lol
