I am not an expert but I believe that as hair is inert, if the chemical signature for weed got into the hair as it was growing 4 months ago, it will still be there until you cut that bit of hair off.
One incident 90 days ago is probably not too bad - it all depends on many factors unique and individual to you. Won't matter if your hair is one inch or one foot long.

It depends on the growth rate of your hair. The tests usually use around 1/4 inch taken as near the scalp as possible, so if your hair grows more than 1/8th an inch a month (which it probably does) you should be fine.
Doesn't matter how long since you last smoked. Weed stays in your system from 2 weeks to a month.
Research tell us that it can take as long as 6 months to keep in hair follicles.
Yes. It stays in the hair for several months and any "hits" will show up.
yes, i just passed a hair folicle test and i did smoke 2 hits about 60 days ago.
2 - 3 days would be safe for a couple of hits. 4 -5 days would be safe for 1 joint. Chronic users should allow 2 - 3 weeks.
3 days max
if you hit weed a couple of hits 2 months ago will it show in your hair
As far as i know, hair tests can go as far back as 6-8 months
None

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.
yes it will. it lasts a minimum of thirty days and hair tests can show for years
