Blonde remy hair - how long should it last

I wear Bohyme in #613 and/or #22 & #24 sometimes, and I get at least 3 installs out of it (average 6/7 weeks) each install, before I am ready for new. None of the Bohyme is in poor enough shape to throw away, in fact I still have all of the Bohyme hair that Ive worn in the past 2 years. I put it away for future use. I keep telling myself that Im going to make clip ins or hairpieces out of them!
