I tried the invisible part method last year after seeing Youtube videos and never again will I do it. Applying glue to your hair is a NO under all circumstances. Please do not apply glue to your hair! Instead you can use a closure. A top closure is a top piece that is added to the to the crown of your head to give the illusion of a natural part.
I have known about the existence of closures for a while now but they never appealed to me because I would always see people glue it on and I have a NO GLUE RULE.
Recently I came across two Youtube videos that show how to wear closures with no glue at all.
This is how to sew on a closure
Another option is to wear it using the elastic band method.
The elastic band method is so genius... great method for those cannot do cornrows or sew hair.
I will be purchasing a lace closure with my next hair so I can try out both methods for myself. I hope this post helped someone.
Have a wonderful week :)
