See Lace Closure reviews and prices on Amazon:
Silk base closures look more like skin, but can be difficult for some stylists to lay flat without glue. Silk/Skin closures are typically more expensive.
Lace closures require a bit more prepping and dressing. To help it blend better, you can bleach the knots and/or use a Q-tips to apply foundation make-up to the part, making it blend with your skin tone.
Free part, middle part and 3 part closures are available.
