If your hair dye is fresh, we ask you to wait at least one week after your color stops coming out in the shower or color remains on the towel following your shower. We understand hair treatment is expensive and would not want your freshly dyed hair to be ruined.  New hair dye will also etch the inside of our tank and cause us to shut down the tank for remediation. If you use any straightening treatments, especially with keratin, the salt may also disrupt the hair treatment.
