Help me make the most frugal decision. Move up hair extensions for $300 or remove wasting $1000 worth of life to them ?

I have full and long hair mid back but wanted hair down to my lower back and spent (an insane and stupid) $2000 in hand tied hair extensions. Have had them since February and the hair will last me until January. I have to move them up every 2 months for $300.

The decision in itself was the opposite of frugal and though I do enjoy the super long hair, the money isn’t justified at all.

So.. do I stick to this and move them up 3 more times for $300 each time or remove and waste half the life of this very expensive hair ? Perhaps could be saved to use later
