okay, i have been reading on here and been able to familiarize and start out a little bit of treatment. i am 6'0 240 lbs and smoked lightly 26 days before the test. before this last time, it was a few hits on very scattered days.. i would consider myself a light smoker during the period to be concerned with. my hair is just over an inch long. i shaved any necessary body hair to keep the focus on my head.--the shampoos that i have always used happen to contain propylene glycol as well as the hair gel that i have been using. 2 days ago i had a clarifying treatment and a relaxer done to my hair at the salon (my friend works there so she knew exactly what we were trying to do) the relaxer gel stuff is used for african americans to straighten their hair, its very potent and i could not leave it in for more than 3 minutes before it burnt like hell.. i now have chemical burns all over my scalp. i waited 24 hrs after just rinsing it out and washed my hair several times with paul mitchell 3. i have also in the past week been using neutrogena t sal with 3% salycitic sp*? acid. tomm when i wake up before i go, i will wash several times with pm3 and t sal then follow up with a cholesterol gel conditioner which contains propylene glycol.
from what i know, i am going to an orientation tomm at 1 oclock and during the orientation they will give us 1 hr to go to the testing facility and get the test done. it will be hair and urine.. i believe my urine to be clean (i drink alot)
my questions are... when i am sent to the testing facility right before the test, i can try to go to my friend in the salon and have anything done to my hair.. Any suggestions on what to do basically 1 hr before the test???ANYTHING??
2nd question... before i use pm3 the last time tomm, should i do a baking soda wash first??? i have not included this at all yet.
my hair seemed fried after the relaxer, and after the 24 wait then wash, i decided to use my hair gel with prop gly in it and my hair really doesnt feel too bad now. my scalp is trashed though, very burned. a

thank you for taking your time to read and help me out, any suggestions would be greatly appreciated.
