Wearing extensions continuously?

My hair matched well, my highlights were just a little harsh. I'm okay spending $1500 every 12 weeks as long as it looks good. Maybe that is silly of me. This is my first time with extensions that weren't clip-ins, so I felt like I needed to pay a lot to get the best results I could, plus this was my regular salon and I feel confident with the stylists there.  I had a consult in August and was told my hair was too short then and to wait 3 months so that I would get nicer blending. I appreciated that they didn't just say "sure" back then and take my money (which I feel a lot of places would have done)- so for me, they started out on the right foot and I feel like I got excellent work for the price I paid. We'll see if I still think the same thing this time next month, right? :)

This is something I've been wondering also, but for different reasons.  I've had extensions since July & it's making me nuts that I can't give my scalp a good scrubbing!  I mean, I guess it's clean b/c I know the shampoo & water hits it, but I'm dying for a good scrubdown.  I'm wondering if it's healthier to take the extensions out periodically for at least a few days & let your scalp "breathe" a little, so to speak?

Thanks for the reply! i don't want to reuse the hair- new hair every three months is fine by me. I just didn't want to have to go a few weeks with the short hair in between installs.

I just had my first install one week ago with Cinderella fusion extensions. I absolutely LOVE them! My question- I am able to afford maintaining these and replacing them properly (this set was $1500, plus a $250 tip). Does that mean that every 3 months they can be replaced (re-install)? Will I have to have them taken out and then wait between installs for a few weeks or more? Can my stylist just taken the ones that need repair out and replace them? My real hair is cut in the Posh bob- these extensions are 22 inches.
