Does it matter if you do the treatments spread out? I have already bleached my hair once, Sun, and had to redye it twice because the first redye didn't come out so great. I was going to do 2 full treatments of the TW. One today, Wed, and the other on Sat right before the test. Do you think that should be sufficient? My last smoking session was mid Feb..and just a few times a week before that. Please let me know if you have any thoughts. I really appreciate all your help, this job means a lot to me.
