Lacefront Wigs: Donts
DO NOT glue down your lacefront wig. I have seen people wear their lacefront wigs and the residue of the glue is still visible along the hairline. A lot of people use glue but I wouldn't recommend it just because I worry about the long term effect the use of glue could have on your hairline.
DO NOT wear the wig way in front of your natural hairline, this will create a very unnatural looking hairline and that helmet look you do not want.
What I used to do: I would part my hair from temple to temple leaving some hair out in front. Then I would attach the lacefront to my hair using the combs and then comb the left out hair over to cover the lace front. This would create a more natural looking hairline because from the front it is my natural hairline showing. Also it gives you a little bit more parting room since a lot of lace front wigs do not come with a lot of parting room.
One good thing I can say about lace front wigs is that they are a good protective style. But other than that, I would not wear one again because it is hard to make them look believable without leaving some of your hair out in front. This eliminates the "purpose"... I might as well have worn half wigs.
I would recommend Glueless full lace wigs because I have seen a number of nice ones on Youtube and they do not require you to use glue and can be parted anywhere.
