I faux bleached the knots at the part with pressed powder (lots of peeps use powder foundation but I find pressed powder to give a less dense look and excess is more easily brushed off of the hair IMO). It's technically a glueless wig, but I found that I couldn't get the wig to lay down how I needed it to without adhesive so I applied a thin strip of glue about 3.5 inches wide across the top of my forehead just to help the unit stay in place. Then I took a tiny dab of liquid foundation and patted it into the the very edge of the lace and the very top of my hairline where it meets the wig to help soften the demarcation.
Sorry, that was a lot of text! In essence:
1. Use pressed powder on the part
2. Glue just the very front of the lace down RIGHT in front of the hairline (like, I'm taking less than a half-an-inch away)
3. Blend with liquid foundation at the very edge of the lace.
Hope that was clear enough, if not, feel free to PM me :)
