Discard Unused Solutions
But I have always wondered why and what damage would it do after being stored away? My thought is it loses its' ability to do the curling and stabilizing am I correct?
In many perms the main consideration is the fact that the perming chemicals will lose their potency after opening and exposure to the air. However, there are some perm formulas that are "self-heating" or require an activator and which could continue to react if stored away.
Even if you managed to find a means to re-cap the mixed chemicals, the reaction would give off by-product gasses that would build up and potentially explode the container.
Aside from weakening solutions and potentially dangerous build-up of chemical heat, there is also the matter of caustic fumes that are impossible to control and would constantly be wafting throughout the area where the remnants are stored.
