Review title is wonderful to add thickness! [SEP] These are the first extensions I've ever owned.  I've worn them twice now -- and overall, I'm enjoying them.  The bleached blond streaks are very bleached -- too much so for my hair color (dark blond), so I plan to darken these streaks with a darker hair color.  We'll see how that works :-)  I wish I'd gotten the more solid, dark blond or light brown.  I purchased the 18&#34; extensions based on other reviews that said they are very thin at the bottom -- I wanted more thickness to my hair, not more length (although I would have been open to additional length if that worked out) and I wanted enough length that I could trim them, if needed.  I'm glad I did this -- I was able to cut off about 2&#34; of very wispy ends to match my own hair length.  When I clipped them in before cutting them to length, the wispy ends looked obvious and weird where they extended beyond my own hair length because there just wasn't enough hair at the ends to look right.  In any case, when I cut them to match my own hair length, they did exactly what I wanted -- I ended up with a nice thick braid.  These extensions are totally straight -- to achieve the look of the woman in the photo with wavy hair, you'd need to use a curling iron or curlers to add that wave.
