I've been wearing hair for a while. And I've come across a few "you HAVE to do this", stuff that works for me, but everyone is different.

I must apply a thin layer, using a cocktail stick.
Then use a hairdryer for 1min on medium to hot, I time myself.
Then repeat at least 3 times.
Press the lace in gently with the teeth from the comb.

Try superstick and see how it goes.
