Detox Shampoo at Shoppers Drug Mart: What's on the Shelf, How to Choose, and Drug-Test Shampoos

Updated 22 Oct 2026 · By the DrugTestAnswers Editorial Team

If you're in Canada and want a detox shampoo today, Shoppers Drug Mart is the obvious stop: it's the country's biggest pharmacy chain, with a large beauty section in most stores and an online shop at shoppersdrugmart.ca. What you'll find there are beauty clarifying and detox shampoos, the kind that strip product buildup, oil and hard-water minerals. What you generally won't find are the specialty shampoos sold for hair drug tests. This guide covers both: what Shoppers lists, how to choose and use one, and straight facts if a hair test is the real reason you're shopping.

Detox shampoos listed at Shoppers Drug Mart

Shoppers' range changes by store and season, and the bigger beauty-boutique locations carry more premium brands than small neighbourhood pharmacies. When we looked in October 2026, its listings included products like these:

Prices on the shelf vary, and Shoppers runs frequent beauty promotions and PC Optimum points events, so the same bottle can cost noticeably different amounts from week to week. If a store is out, the website usually lets you check stock or order for pickup or delivery.

How to pick one at the shelf

Read the back label for a few things before you buy:

• Your main problem. If you live with hard water (much of the Prairies and southern Ontario), look for chelating ingredients such as EDTA or "removes mineral deposits." If dry shampoo and styling products are the issue, almost any clarifier will do.
• Cleanser strength. Sulfates or olefin sulfonates near the top of the list mean a strong clean. Isethionates, glucosides and betaines are milder. Strong is fine weekly for oily scalps; dry or curly hair usually prefers mild.
• Colour-treated hair. Look for "colour-safe" on the pack and wait a week or two after a dye job before clarifying. Our page on detox shampoo and colored hair explains why.
• Fragrance. Many detox shampoos are heavily scented. If your skin reacts easily, look for fragrance-free or test behind the ear first.
• Size versus how often you'll use it. A detox wash is used once a week or less for most people, so a smaller bottle lasts longer than you'd expect.

Using it once you get home

Every brand's label comes first, but the routine that suits most clarifiers looks like this: soak hair with warm water, squeeze out the excess, work a coin-sized amount into the scalp with your fingertips, leave it a minute or two, rinse well, and condition the lengths. Most people use a detox wash once a week or every other week and a gentle shampoo the rest of the time. Our step-by-step guide to using detox shampoo goes deeper on timing by hair type. In winter, when indoor heating dries hair out, it's normal to need it less often.

Signs you need one, and signs you're overdoing it

• Need one: roots greasy a day after washing, hair that looks dull even when clean, curls that won't hold, styling products that stopped working, or a waxy feel near the scalp.
• Overdoing it: a tight or itchy scalp, flaking, frizz, rough ends, or hair that tangles badly after every wash. Space the washes out and add a richer conditioner.

Ask the pharmacist about scalp problems

One advantage of buying at a pharmacy: if what you're dealing with is more than buildup, such as persistent flaking, redness or itching, the pharmacist can point you to a medicated option for dandruff or seborrheic dermatitis instead. A detox shampoo cleans the scalp; it doesn't treat those conditions. If symptoms last more than a few weeks, see a doctor.

Drug-test shampoos: why Shoppers isn't where you'll find them

Some people search for detox shampoo because they have a hair follicle drug test coming up. The beauty clarifiers above weren't designed for that, and their makers don't claim otherwise. A hair test measures drug compounds and metabolites locked into the hair shaft as it grows, and the lab washes the sample first to remove anything on the surface. Removing buildup from the outside of the hair is a different job.

The product usually discussed for hair tests is TestClear's Old Style Aloe Toxin Rid, which is sold online by TestClear rather than through Canadian pharmacy chains. Here are the facts:

• Maker's directions: a multi-day routine of roughly 15 washes in the days before the test, the whole bottle used, with the shampoo left on for a few minutes each time.
• Evidence: no independent published study shows that it, or any shampoo, gets someone under a hair-test cutoff. Online reviews are personal accounts, not proof.
• What's certain: not using during the period the test covers is the only sure way to pass.

Ordering to Canada: TestClear is a US company. Its shipping policy says it has shipped to many countries, and that international buyers are responsible for import paperwork, customs and brokerage fees, duties and taxes. Factor that, plus cross-border shipping time, into any order, and check at checkout that your product ships to your address. Our Aloe Toxin Rid review and how-to guide covers the maker's schedule, and our where to buy Aloe Toxin Rid page explains why buying direct matters. You can also view it on TestClear's site.

Before buying anything, a home hair drug test is the more useful first step. It tells you privately whether you'd likely test positive, which may make the rest unnecessary. The button in the middle of this page links to TestClear's Hair Confirm kit; the same shipping and import notes apply for Canadian orders.

You may also see the Macujo and Jerry G routines recommended online. They combine shampoos with vinegar, acne astringents and, for Jerry G, bleach and hair dye. They aren't backed by independent evidence, they can cause chemical burns and serious hair damage, and bleach must never be mixed with vinegar, acids or household cleaners because the combination can release toxic gas.

A note on workplace testing in Canada

Workplace drug testing in Canada is generally more limited than in the US. Human rights law and arbitration decisions mean testing is usually tied to safety-sensitive jobs and specific circumstances, and the rules differ by province and by whether the employer is federally regulated. Hair testing is less common than urine or oral fluid testing for many employers. If you're unsure what your employer can require, ask HR for the written policy.

Tests this page doesn't cover

Don't use any product or routine to try to change a US DOT test (including CDL drivers crossing the border), an FAA, federal-employee or military test, a transport-safety program, or any court, probation or parole test. Tampering in those settings can be treated as a refusal and can carry legal consequences.

Tampering with a drug test may be illegal and can count as a refusal or failed test, and the only guaranteed way to pass is abstinence.
