Also, if THC is kept in the fat cell is there a way that they can be released into the hair at any time so long as they are in the fat? You say that waiting 7-10 days will be more than enough for new hair to come out clean so is it possible that if the THC stays in the fat longer than the hair is it possible that it will get released from the fat into the blood and then show up in the new hair growth, even after the 10 days?
bsynder21 Reviewed by bsynder21 on . Hair test Hi I was wondering just how the hair tests worked for marijuana. Hypothetically speaking, if a person smoked for the first time ( lets say last week) I'm wondering how long it will take for them to get clean. What I mean is if a lab needs the first 1.5 inches of hair which takes on average 90 days to grow how long will it take for none of their hair to show traces of THC? On average how long will it take the hairs on their head and body to show no traces of THC while growing? Rating: 5
