Preparing for fusion install

Long time lurker - first time poster!  First of all - many thanks to all of you for all the information I've gotten on here.  I've had extensions for years - always used the fusion method- most recently GLs, however my extensionist is now in her last year of law school so I'm on my own.

Just purchased D-Lux fusion u-tips & I want to be sure I do all the right things to have a successful install. Couple of questions:  Should I wash the fusion strands before installation?  Also - what should I wash my own hair with as a preparation for the best possible bonding (very fine, slippery hair).  My hair is medium brown with highlights just done yesterday (18/22 D Lux is a perfect match). 

Thanks for your help! 

It came out great!!!!  It was a bit tough putting them in by myself though, but I did a pretty good job of it.  Wish I had taken pics. I have thin, fine hair & the D-Lux works just great.  The 18/22 color is perfect.  Thanks to all of you on this board - I've been researching in lurker mode for months and finally took the plunge!  My extensionist is now a busy law student & is no longer doing extensions - so this was my only hope.  So far - so good.  I'm interested to see what will happen after a few washes.
