Been wearing well over 40 years and skin units for a long time!
Maybe my method will help you ! It works great !
For adhesive I use Davlyn, black label, 1/2 oz., comes with applicator brush. Been using it for years !
Just apply around the perimeter of the base, maybe 1/2 inch or less. And sometimes I put a few dabs down the middle!
I use the Davlyn, for initial attachment. After a day or two, remove unit, either wipe the base with an alcohol wet cotton ball or under running faucet, rinsing the hair off also.
Now before reattaching, I use Got2b, Freeze Spray, Spiking Glue, or Rubber Cement, all over the base, plus my scalp, light coating on both, wait a minute,or moment or two, and attach, pressing firmly all over!
I do this over a period of a week, ten days.....
Than do a complete cleaning of the base, using alcohol saturated cotton balls, ringing the perimeter, leaving on an hour or so, whatever your time period fancy.
Use the balls after the time period to rub away the Davlyn glue, rinse base, shampoo hair.
And repeat the method! Quick, easy, good results. Been doing this for years !! Before some of you were born !
