How long should you wait to wash your hair after a perm?
At least 24hrs.
Now, why the hell did I know that??? Oh yeah, Legally Blonde...
2 day well u can take a shower but dont use soap in ur hair it will undo the curls
At least 24-48 hours so you don't deactive the ammonium thygolcolate!
if you want it to stay in u should not wash it for 24 hours
