Try styleing without exposing the hairline. As far as getting the WET look, there are products but using the mist leave in conditioner, and then a bit of hair spray to set it and then it shouuld stay wet looking when it dries. You are not familiar with styleing all that hair. What is the density?

Bleaching the knots will make the hairline look a lot more natural. I used Debbies knot bleaching process and it worked well. Is this system from TOPLACE? Ask one of the founders for some help,.
