Hades method improved.
Obtain a pint or so of Propylene Glycol from a respected dealer.
Heat up 1 application to where it is tolerable for a hot glycol treatment to your scalp and hair.
With a dry head & body.
Apply the Propylene Glycol massaging into scalp, hair and other areas that are test worthy.
Distribute evenly and comb through hair
Leave on 6 minutes
Rinse well with luke warm water
Let dry and repeat till your anxiety goes away :-) I would think 5-10 wet to dry applications would remove enough from anyones hair. Just a guess though.
Can also do while wet but I would guess you are increasing the absorbtion by applying it to dry hair. I believe it's increasing absorbtion through osmosis rather than just diffusion :-)
hades65 Reviewed by hades65 on . Theory on method of reducing Cannabinoids in hair Buy some 100% Propylene glycol from a shopping search engine from google, yahoo or similar. A pint can be obtained for about $6. Apply in shower over all hair where you think you could be tested. Rinse and repeat many times. The extraction is probably minimal so repeated application and rinses 25-100+ times improves the results. Time to allow it to penetrate hair cells is unknown by me. Hot water as well as warmed propylene glycol will increase its penetration. Understanding the Rating: 5
