I remove it to wash 50%of the time. This tides me over so I can keep it clean and only need to remove once every two or three weeks.

I usually throw them away because the hair dries out. Base is never a problem, colour is never a problem really, shedding isn't a problem for me since I started ordering my units with higher densities. I used to have problems with shedding on lower density units but that was years ago. I got tired of looking like I was losing my hair again, so I gradually upped the densities!

But when the hair dries out, you are finished. Nearly natural helps slow down the process, but it will eventually happen, and when it does, no matter how you style the hair, it will look a bit strange. The only way around it is to add some blonde highlights to the piece, and this will magically freshen up the hair and buy you a few more months.

I once made a system last about 10 months. You can darken and recolour the hair easily. Just watch out for the dryness, which can-in severe cases-make it look a bit less natural, and harder to style.

As for the overlap, it isn't an issue at all once the hair is a little longer. But when I had shorter hair, I remember cutting the hair on the base using a thinning shears to make sure it blended exactly with my own hair. I also cut down the base of the unit so that there was no lace overhang and the lace ended exactly where my own hair began.
