The detection of weed in hair is an interesting topic, especially in the context of drug testing. Unlike other testing methods that may detect weed use over a short period, hair follicle drug detection times are longer. This is because THC, the active compound in weed, is deposited into our hair follicles. As our hair grows, traces of it remain embedded in the hair strands. Understanding how long marijuana stays in the hair is crucial, if you are concerned about drug testing, as it may impact personal, legal, and employment schemes. In this article, we will discuss how long weed stays in hair, how hair drug tests work, what substances they can detect, which employers use hair drug tests and, of course, some tips and products, such as Old Style Aloe Toxin Rid Shampoo and Zydot Ultra Clean, to beat a hair drug test.
Finding strands of hair in your cannabis buds can be annoying and off-putting. While a few hairs likely won’t impact the quality of your weed, removing them improves the appearance and can prevent gagging when smoking. Luckily, getting hair out of weed is easy with the right techniques.
In this comprehensive guide, we’ll explain why hair gets into cannabis and show you various methods for effectively removing it With a few simple tools and steps, you can have hair-free buds that are ready to grind and enjoy
Why Does Hair Get Into Weed Buds?
Seeing strands of hair in cannabis may seem strange, but there are a few common reasons it happens:
-
During growing – Hair can detach from the grower and contaminate sticky, resinous buds. Air circulation in the grow room also causes loose hairs to blow onto the plants.
-
During harvesting/processing – Hairs can transfer from trimmers’ hands, clothes, and tools onto the weed. Cutting and handling buds creates opportunities for contamination.
-
During packaging – Stray hairs may fall into bags and containers as cannabis is weighed out and packaged for sale. Storage areas likely contain hair that can get incorporated.
In general, small amounts of hair are inevitable when cannabis is exposed to people and environments However, with care and cleaning, it’s possible to remove hair and have mostly strand-free weed
Methods for Removing Hair from Cannabis Buds
If you spot pieces of hair in your cannabis, take heart knowing they can be easily eliminated. Here are some simple, effective methods for getting hair out of weed:
1. Use Tweezers or Small Scissors
For a few visible hairs, precision tools like tweezers or small scissors are all you need. Carefully pluck or snip out the strands – this works great for large, easy-to-grab hairs. Check the buds closely and remove any remaining hairs you find.
2. Use a Small Bristle Brush
For smaller hairs diffused throughout the buds, a soft brush is ideal. An old toothbrush, paintbrush, or cannabis trimming brush lifts hairs out painlessly. Gently brush over and around buds, coaxing hairs to detach. Avoid mashing or damaging the weed. Check with a magnifying glass to spot any stray hairs.
3. Try a Sifting Screen
Sifting screens offer an easy way to let gravity remove hair. Stainless steel mesh screens with an appropriately sized hole (around 220 microns) will allow hair to fall through while retaining buds. Place buds on the screen and gently shake side-to-side or up-and-down. Hairs and other debris pass through the holes, leaving cleaner weed above.
4. Use a Vacuum Cleaner
Surprisingly, a vacuum cleaner can suck up and remove loose hair from buds quite well. Use a hose attachment and low suction power to gently vacuum over the weed. This lifts out hair that brushes can miss. Check buds closely afterwards to remove any remaining hairs.
5. Rub Buds Between Palms
For a low-tech approach, rub cannabis buds between your palms in a rolling motion. The friction from your hands will grab many hairs and roll them into balls that can be picked off. Go slowly to avoid damaging trichomes. Check for any leftover hairs stuck deep in buds.
6. Wipe with a Microfiber Cloth
Microfiber cloths are useful for trapping and removing hair through static electricity and tiny hooks on the fabric. Drape a clean cloth over your hand and gently wipe/roll buds against the surface. Hairs will cling to the cloth each pass. Check buds closely and re-wipe to get all hair.
Tips for Preventing Hair in Your Cannabis
While removal methods are handy, preventing hair contamination in the first place is ideal:
-
Cover hair and wear clean clothes when growing, trimming, or packaging cannabis. Hoods, hairnets, and gloves help.
-
Keep grow rooms and processing areas clean and minimize loose hair/debris. Use positive air pressure.
-
Inspect packaging materials for hair before use. Clean storage containers regularly.
-
Limit direct handling of buds after trim. Use sanitized tools when possible.
-
Store cannabis in sealed containers after cleaning to prevent re-contamination.

Use a Detox Shampoo
Detox shampoos, such as Old Style Aloe Toxin Rid and Zydot Ultra Clean, claim to penetrate the hair shaft and remove toxins. Although they are safe to use, their effectiveness is widely debated. You don’t need to shave your scalp and entire body hair to cheat. You may also avoid using bleach or other harsh methods which can damage your scalp and hair.
Choose a good-quality shampoo for hair purification. But it is recommended to use detox shampoos at least 15 times before facing a hair drug test. The more drugs you have used, the more often you will need to wash your hair.
Examples of hair follicle drug testing shampoos include:
- Old Style Aloe Toxin Rid Shampoo
- Zydot Ultra Clean
- Nexxus Aloe Rid Shampoo
- High Voltage Folli-Cleanse Detox Shampoo

THC or Tetrahydrocannabinol is the primary psychoactive compound found in marijuana. It is responsible for the ‘high’ that users experience when they consume marijuana.

That explains why THC is detected in our bodies long after the effects have worn off.
How long weed stays in your system depends on several factors, including the body metabolism, fat percentage, potency of drugs, frequency of use, and the testing method. Here is a simple comparison.
Test | Urine | Blood | Saliva | Hair |
Occasional Use | 3-7 days | 1 -2 days | 1-3 days | Up to 90 days |
Regular Use | 1-3 weeks | Up to 7 days | Up to 7 days | Up to 90 days |
Heavy Use | 30 days or more | 7 days | Up to 30 days | 90 days or more |
