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 cannabinoid reducing process:
Propylene glycol is a solvent and can be used for making of THC tincture as well as the active ingredient in many extraction shampoos. The difficulty with Carboxy-THC extraction is due to it being deep within your hair that is surrounded by numerous hair cells. Penetration of the solvent happens through diffusion. Diffusion is the resulting net transport of molecules from a region of higher concentration to one of lower concentration. Using 100% Propylene glycol increases the effectiveness of the diffusion process by increasing what little bit may penetrate and come in contact with Carboxy-THC. The solvent binds with the Carboxy-THC within the hair and then is washed out.
What needs to be further studied:
1. How quickly Propylene glycol diffuses across the cell membrane of hair and how long should it be soaked before rinsing? There is a double edge sword here. Allowing it to soak more will increase the time of the process thereby reducing the applications & rinsing you are willing to put up with. A mix of a few prolonged soaks along with many quick soaks & rinses could be the best approach until more is known.
2. What percentage Carboxy-THC is washed out? Washing out something as minor as (for example 0.5%) on each rinse could make this a very time consuming process as well as a big chance of failure if not enough rinses were done.
3. Do better solvents exist for extraction? Propylene glycol is virtually a non-toxic extractor and having another solvent that diffuses better or binds with Carboxy-THC better might not be as good if you can't apply it as long due to toxicity.
