So,
Being a skeptic, I have a system that I wanted to experiment with.
This is a little crazy so hang on.
I wanted to experiment with a topper and a variety of adhesives. . .for 1) undetectability 2) alergies 3) Strength.
I shaved a part of my upper thigh and preped it with alcohol and scalp protector.
On the left side of the system I attached with Pro-Flex tape. The blue one with the holes in it (the tabs).
On the right side I used walker no shine (from a roll).

Afrer the completed attachment, I sprayed the hair wet and applied blue max sealer for that healthy slilck look and combed the system in a comback fashion.
When I pull on the hair of the hairline the hold is so strong (both kinds of tapes) that my skin is lifting with the hair.

i intend to report how it goes over the next few days.
For now I have to say that the hairline (thigh-line LOL) looks very good so far.
I will give that area 24 hours to let it set well and then hit the shower and expose it to cool water gently.

I did something similar with liquid adhesives a few weeks ago.
Granted I'm not an expert yet. But, I found them to be unforgiving.
The white type glues (2 layers) worked fine but tend to attract dirt like no ones business.
The ultra-hold is super aggressive in it's tackiness. It needs perfection when it comes to applying it on the scalp.
It also attracts dirt over the course of a few days.

Will be keeping you all posted on how this all goes
Thanks,
