Where/how do you apply it?
Do you apply Fray Check only on your hair system before you put it on your head or after; on your skin, when your hair system is all fixed, (you put it directly on your forehead where your lace/frontline begins to hide any demarcation)?
If it's the 2nd option; has it ever produce a rash or irritation to put that product directly on your skin?
