Hydrogen Peroxide Question, Hair testing

Heres my info:
I recently failed a psychemedics hair test with a level of 6.8 pg..I had not prepared for the test in anyway (it was a required test for school). Anyhoo, I was informed that I have to take another test 100 days after the original test date. I'm not going to continue smoking, but I was told about the 100 days after policy 11 days after the original test and I smoked everyday save 1 or 2 of those. From my understanding it takes 5-10 days for the metabolites to grow above the scalp so I think it is a perfectly reasonable fear that I could completely abstain from use and still fail with at a low-level.

My question concerns the use of hydrogen peroxide. Is it feasible that periodically treating my hair with low strength-household (3%) hydrogen peroxide could lower my metabolite level to a negligible number? My parents aren't exactly supportive of my drug use, so I can't bleach/re-dye without them accusing me of continued use and I would rather my hair gradually lighten than have to explain a drastic change.
