Go to a beauty supply place, buy the strongest hair relaxer you can find. Propylene Glycol should be the primary ingredient. Ammonia would be a good ingredient as well.

Leave it in as long as you can stand.

With 45 days clean, you have a pretty good chance.

If you can trim your hair to a little over one inch, that would help too.
Jerry G Reviewed by Jerry G on . Quest Diagnostics Test Question I just got my Hair/Urine Custody and Control Form. Under the type of tests it has the following listed 6405N SAP 5-50 GC/MS 1793N SAP 9-50/2000 6633N SAP 10-50 GC/MS and 19870N HAIR-5 Each test has a box next to it where one could place a check mark, but there is no check mark on any of the boxes. After searching the codes it looks like 6405N SAP 5-50 GC/MS, 1793N SAP 9-50/2000 and 6633N SAP 10-50 GC/MS are all urine tests. Rating: 5
