The rapidly growing reports of drug abuse in the United States and other neighboring countries have made research organizations worried and determined to check its growth and find an immediate solution to lessen it. Found to be ten times more effective than urine drug testing, hair drug testing has been found to detect drugs such as marijuana, cocaine, methamphetamine, phencyclidine, and opiates, these five drug classes are mandated to be tested by the government.

This method of drug testing is frequently used for tremendous critical situations where there is zero resistance for drug use. Hair drug screening can detect drug use over a much longer period of time compared to other tests and not to mention this is the most convenient method to use even in schools and in offices regarding the testing of students and the employees respectively, to determine whether or not they have drugs in their system.
Handy kits containing instructions on how to perform the test is given to those who are to be screened for drugs. The hair sample is taken near the scalp and a minimum of 40 to a maximum of 120 hair fibers are collected for this test. If there is lack of hair on the head, hair on the body may be applied as a substitute, this includes hair on the face, legs and arms or even on the pubic area, but be aware that body hair and hair in the head do not grow at the same rate and so the results may vary.

After this step, the hair specimens are sent to the laboratory to be evaluated. Lab officials evaluate the hair for drug residuals that are stored when the person recently took the drug. They measure the molecules of the substance and their particular metabolites that are conceived after the substance has been altered by the human body. The reason that they examine the hair is simple; when we take drugs, it enters our system as with anything we ingest like food, drinks, and medicine. All of these are mixed with our blood, and as we are all aware of, blood nourishes all parts of the body including the head. Hair follicles trap and filter traces of the drug in the later period. And as the gradual growth of hair is inevitable, these chemicals are found to be stored in the hair and can be found during the hair drug test. The possibility of the chemicals becoming a part of the hair is also great.

I have to take a hair follicle test for cocaine….i am desperate..what should i do?
Hi, Tania.
It depends on 2 factors: when was last time you took cocain and how long is your hair. Hair growsin an inch every 2 month, so if your hair is short and last time was long ago – you have a chanse to pass.
I’d recommend you to buy and use masking shampoo: http://mbdetox.com/Ultra-Cleanse-Hair-Cleansing-Shampoo-Conditioner_p121/ / Use it and you’ll pass your test.
If you have questions – just call the phone on that site (it’s toll free) and they will help you
I have hair test in a week or so and barely smoke last time I did was possibly July. Will I be ok?
Please delete previous post.
I smoked for the 1st time on OCT 1ST took like 3 pulls didnt even no wht to to and was blowing it back out and took a urine test NOV 3rd and passed it just took a hair test on Dec 15th…Do you think i will pass the hair test???
Hi, I was aware of the NYPD that I have to take a hair follicle test and I have long dreadlocks past my shoulders. I’m planning to cut my dreadlocks because I am too concern about this test. I’ve been growing my hair since December 2006 and on December 31, 2006, I smoked marijuana for the last time. On Friday December 3, 2011, five years after the last time I smoked marijuana I was hanging out with a friend who smokes marijuana and started smoking marijuana for that night only. I think that I only smoked about two or four puffs of it while inhaling it in my system. Do you think I’ll pass the test by the end of January if I only smoked about two to four puffs of marijuana? I heard it stays in your hair for a long period of time.
Hi, Jay.
Yes. I think we can say it stays in your hair forever and the only way to remove it it’s cut the hair.
So let’s checs. You’ve smoked 31-Dec-2006. 5 years have passed. Hair grovs an inch every 2 month. 5 years, 12 month in each, 2 inches per month – so if your hair is shorter then 30 inches (it’s nearly 20-inches dreadlocks, which I think are the coolest thing in the universe after Star Track and jamaica tour).
You’ve smoke last time 25 days ago and a small amount. For now nearly half an inch is dirty. Knowing the police methods I can say you that mostly sure you’ll be clean!
So you don’t need to cut your dreadlocks. Oh, and you know what? You can simply check yourself with home test like this one: http://mbdetox.com/Home-Hair-Test-Kit_P50335/
Ok thank you. That’s the information I’ve needed it because I was worried about how long it stays in your hair. Well explained. Thanks again!
I have to take a hair test on Tuesday Jan. 10th and i had smoked on new years eve Dec.31st. what can i do to get my hair straight.
I have to do a hair follicle drug test on Friday but I’m worried because I’m around people that smoke marijuana so Im wondering if I will fail the hair follicle test
Had 8 hits off crazy joint on Oct 30, 2011…now Feb. 8, 2012…6′ 3…225…athletic build…..had very little fat at time of smoke..little more now…any THC test that I would fail????
I weigh 135 and im 6 foot i am trying to get this job but they do hair follicle test that at the time of my interview i havent smoked in a little over two months. From what i know about the test is that they dont test back that far. will i pass the test if not what can i do to pass the test.
how does somebody whos mad for it aka drugs beat a hair test
I smoked for 6 year on a daily basis quit for 5 months and started again for about 3 months. How long do you think it will take for me to pass a hair follicle test?
To add to last comment I was smoking marijuana.
i am taking a company hair test in 6 months and i quit a week ago and i was an habitual marijuana smoker, like almost everyday multiple times a day for 3 years… and i was wondering if i waited 6 months and just cut my hair down to 1 and a half inches would i be able to pass?
i have a hair test in a couple hours. I have not done any drugs in three months. do you think i will pass?
Amber
How long is your hair? Your hair grows approximately 1/2 inch per month and if is longer than 1 1/2 inches then whatever drugs that you have done before that will show up in your hair. If you can postpone your test you can use a detox shampoo to mask the drugs in your hair. Zydot http://mbdetox.com/ZYDOT-Ultra-Clean-Shampoo-and-Conditioner_p96 is a good shampoo for marijuana but if it is something else then you will need to use Follikleen http://mbdetox.com/Folli-Kleen-Intense-Hair-Cleanser_p118 in addition to the Zydot. You will need one package of each for every 5 inches in length of hair.
Tried it 5 months ago. Got hair test. Longest hair is 8 inches. Hair is cut every month about an inch off. Will I pass
Stupid
You probably will need some type of detox shampoo like Folli Kleen http://mbdetox.com/Folli-Kleen-Intense-Hair-Cleanser_p118 to mask the THC in your hair. You would need one bottle for every 5 inches in length of hair. If you would like to do your own test run by a private lab you can get a home hair test kit http://mbdetox.com/Home-Hair-Test-Kit_P50335 and get the results in complete privacy.
So you think it is still in my hair after getting it cut every month ?!? I tried it once.
Stupid
Unfortunately the THC does not leave the hair until it grows out. It is kind of like on a time line where the toxins enter at the root and moves along with the growth of the hair.
hi i was wondering i quit weed today and i have a hair test around January or maybe march and i was wondering if i went bald the September would i be clean to past my test?
and im planing on going to the gym and i drive about 5 glasses of cranberry juice a day should i be ok ?
love weed
Hair test is the hardest test to pass. Your hair is a dead element. The only way to clean them out permanently is to clean your body/blood, then the hair that will grow will be clean hair (might take up to 3-4 month, since the speed of hair growth is about 0.5 inches per month). As long you have a toxin in your system (by
ingestion) it will be in your blood stream, which travels through the hair follicles and deposits some toxins so that as your hair grows out
it carries these toxins with it. It’s one of the many ways your body has to clean itself from unwanted impurities like drugs. Blood might be clean in 1 month. Hair samples (usually its 1-1.5 inches of hair) are being taken from different parts of the head (lab personnel may need to obtain up to 100 strings) and they will test for up to 90 days of your usage history.
So if will stop now toxin should be put of your system, and then you will need to cut your hair, to make sure to cut all the hair that with toxins.
love weed
As long as your blood is clean then any new growth would be clean after that but your body hair would still be positive. If you are male then they may take some samples from your armpits or chest hair. Using a detox shampoo like FolliKleen http://mbdetox.com/Folli-Kleen-Intense-Hair-Cleanser_p118 or Zydot Ultra Clean Shampoo and Conditioner http://mbdetox.com/ZYDOT-Ultra-Clean-Shampoo-and-Conditioner_p96 would mask any THC in the hair on your test day and after they remove the sample from your body.
love weed
Keep working out and it will get the THC out of your blood quicker but it will have no effect on the THC in your hair. That has to grow out and be cut out or masked with shampoo.
Haven’t smoked chronically in a year and a half but have occasionally smoked 5-6 months ago. Took a hair test yesterday from my leg. Will I pass?
Ty
Hard to say but five to six months may have been enough time for the hair to regenerate on the leg. A good detox shampoo to use for body hair would be FolliKleen http://mbdetox.com/Folli-Kleen-Intense-Hair-Cleanser_p118 to be used on the day of the test.
so your saying i should wait a month before i go bald ? i play basketball everyday and i been juicing it and i drink about a quart of water a day. and when it’s a month im going to shave all my hairs out of my body do you think i would be ready by January? and btw i already bought the folliklean and zydot as well
How long does weed stay in ur hair?
love weed
You can use the FolliKleen and Zydot on test day and you will be fine. Just make sure you use some on your body hair (underarms and chest).
Sck sck
The metabolites from THC will stay in your hair indefinitely until they grow out. As long as there are THC metabolites in your blood they will be deposited in your hair follicles. You can mask them for up to 8 hours by using a detox shampoo like ZYDOT Ultra Clean Shampoo and Conditioner http://mbdetox.com/ZYDOT-Ultra-Clean-Shampoo-and-Conditioner_p96. The chemicals in the shampoo will mask the metabolites for up to 8 hours while the follicle is still attached to your head and indefinitely once the hair follicle is cut off.
can you tell me how much of zydot i need to buy if im going to use it for my whole body?
hello, i took one puff of weed but i didnt put my mouth on the blunt itself my friend had took a hit and blown in into my mouth while i in hailed it. (not that it would change anything) but i am trying to find a job and the jobs i am looking for do hair drug testing, i last took this hit about maybe 2 weeks ago august 9, 2012 and today is obviously august 24, 2012 and i am worried that i may not pass a hair drug test any time soon within the next few weeks to a month is there anything i can do or use to pass a drug test?? please help, thank you.
sck sck
For your hair you would need 1 package for every 5 inches in length of hair. If you are a man then make sure you use it on your armpits and chest hair. If your hair on your head is less then 5 inches then I would guess you would need 3-4 packages to cover your whole body.
Also, for body hair you can use Folli Klean https://mbdetox.com/Folli-Kleen-Intense-Hair-Cleanser_p118 (bigger bottle), so you may need 2-3 bottles
chong
There may be very little THC in your hair but unfortunately it will have to grow out it can not be washed out. You can use a detox shampoo to mask the THC in your hair for test day. If your hair is less than 5 inches long then you would just need 1 bottle of Follkleen shampoo http://mbdetox.com/Folli-Kleen-Intense-Hair-Cleanser_p118 to hide the THC in your hair. If longer then use 1 bottle for every 5 inches in length.
well i waited a a month and i shaved my head and all my hair on my body so should i be good
I smoked like 21/2 wks ago just a couple of hits, and before that I went a full year and a half without smoking, ain’t never cut my hair on my arms,legs or underarms only my head hair been getting cut. Would I still pass?

If it is a hair test then you will need to use a detox shampoo for your test. The THC metabolites will show up. The metabolites have to grow to the end of the hair follicle and then be cut out. Your hair grows about 1/2 inch per month and you may want to put some on your armpits or your chest hair because they may take sample from those areas as well. A good detox shampoo to use on your test day would be the Zydot Ultra Clean Shampoo and Conditioner http://mbdetox.com/ZYDOT-Ultra-Clean-Shampoo-and-Conditioner_p96. If you use this on your test day then you will pass your test or you get your money back.
I have a quick question, I recently have been job interview with companies. I was given this amazing offer and accepted it. I was told I was going to be subjected to a drug screen and randoms if I accepted the job. I wasn’t told until the day of the drug test that I had to take a hair test. (Mind you its my birthday so a wake in bake was in order.) I though I only had a urine exam.. Anyways I rush to the nearest shop and buy two bottles of Folli Kleen. I get home and I wash my hair put the shampoo with a bag on my head for 30 minutes and then I repeat the process but only for 22 mins the second time. I had a comb I have never used so I gently combed then dried my hair and went directly to the place to take the test. I passed the urine exam but IM FREAKING OUT about the hair test..
The reviews on Falli Kleen are so back and forth. I have been researching it so much since after I had to use it.. One of my regulars at my current job got me this job so I would like a total jackass if I fail.. uggghh.. worst birthday ever..
Worried
FolliKleen is a great product and also comes with a money-back guarantee. If it was just THC in the hair then you should be fine as long as you followed all of the directions. Good Luck!!
You think even though I did a wake and bake that morning I;m gonna be ok. Im literally a mess over this. I followed the directions to a T and I repeated it two times bc I am such a heavy heavy smoker. I used quick fix plus for the urine and passed that no problem its just this damn hair test. They said I should know by next Tuesday. I am not expecting good news but if I really do get one birthday wish it would be to pass this test… Im going to be a wreck for the next 5 days. I really really hope with all my heart that this shampoo really does work.. Have you really had any experience with it?? I really worried. This job could literally change my life, I feel so disappointed in myself. If I was on hard drugs I would understand. But its weed… I a great student, employee, wife and mom but I like to smoke pot to relieve myself. I barely drink maybe two times a year but give me a bowl and I am down. ughh. I am just worried bc i didn’t know about it and I did smoke that morning but i really did follow directions and I used two bottles.. please pray.
Worried
We will be praying for you but try not to worry. These shampoos are very effective and have a high rate of success. Just try not to get all worked up about it and you will be fine.
Help! So, I very rarely smoke, however about two or 3 weeks ago I took two pulls of weed and before that, I think the last time I smoked was in may. Even then it was probably only 2 pulls.. I’m not a heavy smoker at all as you can see.. I was just informed that I will have to take a drug test soon for a company that helps women in shelters find places to live.. not sure if it will be a urine, hair, or cheek swab test. Do I need to detox anyway just to be safe?
ummm
You should get a home THC test strip to see where you stand. If you are clean then you have no worries. You can get some exercise in if you are positive and this will help speed up your body’s metabolism to burn the fat cells where the THC is stored. If it is a hair test then you may need to use some detox shampoo like Follikleen http://mbdetox.com/Folli-Kleen-Intense-Hair-Cleanser_p118 and you will need one bottle for every 5 inches in length of hair.
I smoked pot for about a year while i was in college and i found out that the place i wanted to apply to does hair follicle testing….I stopped smoking in july and in august i waxed my chest arms legs and armpits. IT SUCKED. top 10 worst experance of my life but this job is my dream job. as far as i know i should be ok for january. what do guys you think?
joe smoe
The THC can stay in the hair indefinitely until it grows out. Once your blood is clean then any further hair growth will be clean as well but the hair that is already outside of your body may contain metabolites. If you think that your hair may be contaminated then you definitely should use some detox shampoo on your test day. There are test kits that you can use to have your hair sent to an independent lab for private testing. The Home Hair Test Kit http://mbdetox.com/Home-Hair-Test-Kit_P50335 can provide you with a private analysis of your hair follicles to give you the results before your official test to see if you need to use some type of detox shampoo to pass your test.
Hi the last time I smoked was in Oct. 2012 and took 4 or 5 hits off a pipe and the last time I smoked was in September for approximately every day for a week. I went last Friday January 11, 2013 for a hair follicle test for pre employment and used the Clear Choice hair follicle shampoo and followed the directions to a T. Will I pass the drug test? I have not heard anything and it’s been almost 7 days since the testing. Please help!!!!
Dear Red,
During the drug test procedure, a minimum inch and a half long hair sample is clipped from the back of the head near the scalp by the examiner. This allows the test to reveal a minimum 90 day drug history. If the scalp hair is shorter than an inch and a half long, the examiner may look for other areas on the body to take a suitable sample. Body hair grows much slower then scalp hair so a smaller sample can be taken, this will also allow the test to reveal drug history much further than 90 days. So, if you have used THC or other substances 90 prior to your test you will, in all likelihood, test positive.
Red
Dear Red,
I’m not familiar with that particular shampoo but I suspect that no news is good news. You didn’t say how long your hair was and since your hair grows approximately 1/2 inch per month you may have already removed the toxin laden section of your hair and provided a clean sample.
