It looks like it is buildup of glue - and/or too much glue was applied. I would try cleaning it all up as others suggested, then using less of the ghost bond, and leave the area near the hairline without ghost bond, maybe ½ inch and perhaps trying a 2 thin layers of Walker Ultra Hold if you are going for a couple weeks or a month hold. Apply one THIN layer, let it dry, apply another and you should be good to go - would do this around the entire base

I am not expert, but I am learning and moving along – honestly, it looks like too much glue, and dirty for sure. Also, use some rubbing alcohol/ 91% isopropyl alcohol, once in a while to clean up near the hairline, don’t the hairline, just clean right up to it – a makeup sponge helps. I did this during the horrible summer months when I was working outside, kept my hairline clean as a whistle. This is going to be trial and error, but we are all here for you and want you to succeed.
Also, on a side note, if that it sweat and grim buildup, you may want to try a scalp prep from HairDirect like No Sweat – I hear its good stuff.
Again, I am new to all of this, hope this can at least help you along a bit.
