After two-three months
Since it takes about 6 months to 1 year to out grow your hair of any chemicals. It is really good to trim the ends of your hair every 6 to 8 weeks. It is best to not cut your hair for a few months it because it was still grow long enough over the time period depending on how many months you don't cut it.
your hair should grow about 1/2 inch a month. i haven't cut my hair in about 8 months. i have only cut of my split ends. i went from my hair being from my shoulders to my boobs.
dont cut it just do trimming 3-6 months once
Is it 1 or 12 months ago? If you haven't cut your hair for 12 months, then technically, there will be one very minute spot where the tiny amount of THC you inhaled was excreted. It would be nearly impossible for them to test for it after 12 months, especially since it was only 2 hits. If you have very long hair, and you haven't cut it in even longer than 12 months, then the history of your marijuana smoking will be present as long as the portion of hair you had when you smoked it is still on your head. Again, 12 months is such a long time, and statistically, you have probably cut your hair more than a few times, and that portion is long gone. If you haven't cut your hair at all, go in for a trim, as the chances are that the strand with the THC in it is probably at the very tip of your hair, and taking off a inch or so would free you from that. Really, these are all "what-if" scenarios. Only you know when you cut your hair, where on your hair the THC portion would have been, and whether or not it was probably cut away 10 months ago to start with.

Well, to be honest, my hair grew to my forehead in three months, and in six months it grew to be about ten inches or so. So about ten inches does your hair grow when you decide not to cut it for the approximate time of six months.
girls: 2-3 months, maybe 4 if you have thin hair. men : 2 months maybe shorter
sometimes if you had heavy use 4 months ago or a little 3 months ago you can cut it down to 1 inch if you have use in the past 2 months better
yes it can, it will stay in your hair until you cut it
No he did not cut his hair
You can trim your hair so oxygen can get to your roots. only cut at least 1 inch off. do that at least once a month and in a few months your hair will be long :)
