High Voltage Hair Follicle Cleanser Detox Shampoo: Label Claims, Directions and How It Compares to Aloe Toxin Rid

Updated 17 Oct 2026 · By the DrugTestAnswers editorial team

High Voltage's hair follicle cleanser is one of the cheaper, smaller detox shampoos you'll find behind the counter at smoke shops and on marketplace listings, and it's often sold next to the brand's detox drinks. It's built around a single session the night before or morning of a test rather than a multi-day routine. That makes it appealing if your test is close, but it also raises a fair question: what does one 2-ounce bottle realistically do? Here's what the label says, how the directions read, how it compares to Old Style Aloe Toxin Rid, and what's actually proven. We may earn a commission from some links on this page; that doesn't change our assessment.

What the product is (and its name change)

High Voltage Detox is a brand best known for detox drinks. Its hair product has been sold under a few labels over the years, including "Hair Follicle Cleanser Detox Test Shampoo" on older listings and "Folli-Cleanse Shampoo" on the brand's current site. Retail listings describe a 2 oz bottle intended as a one-time treatment. You'll still see the older name on many marketplace pages, which is why people search for it that way.

What the label and sellers claim

Product descriptions on the brand and reseller sites say the shampoo is formulated to remove toxin-related metabolites from the hair shaft, that it can be used on all body hair, and that its effects can last up to 36 hours. Sellers suggest using it the night before or the morning you need your hair clean.

Two things are worth noticing about that wording. First, "effects can last up to 36 hours" implies a temporary cleansing effect rather than permanent removal, which by itself is telling: drugs locked inside the hair shaft don't come back after a day and a half. Second, none of the listings we found point to independent lab data showing hair drug levels before and after use.

The directions, as printed

The brand's directions for the 2 oz bottle run roughly like this:

1. Shake the bottle well.
2. Wash your hair using about a quarter of the bottle (around 0.5 oz), rinse completely and leave the hair damp.
3. Apply the remaining 1.5 oz and massage it in with your fingers only, without combs or brushes.
4. Cover with a shower cap and leave it on for about 20 minutes and no more than 30 (some reseller listings print a longer 30 to 45 minute window).
5. Rinse thoroughly, then towel or blow dry, avoiding combs, brushes, hats and styling products that touched your hair before the wash.

The label also warns to keep it out of your eyes and stop if your skin becomes irritated. If you buy a bottle, follow the directions printed on that bottle, since timings vary between batches and listings.

What the evidence says

A hair test laboratory washes every sample before analysis to strip off oils, styling product and surface contamination. What's left to measure is the drug and metabolites incorporated inside the strand as it grew. For a shampoo to change a result, it would need to pull those compounds out of the shaft in meaningful amounts during a short wash. We aren't aware of any independent, peer-reviewed study showing High Voltage's shampoo, or any consumer detox shampoo, does that reliably. User stories exist on both sides, but they almost never include before-and-after lab numbers and usually involve other factors, such as light use or long gaps.

One session vs a multi-day routine

The biggest practical difference between this product and Old Style Aloe Toxin Rid is the schedule:

Neither has independent proof behind it. The appeal of Aloe Toxin Rid for many readers is that its routine is more thorough and better documented, with long contact times over several days rather than a single wash. If you want to compare, here's the Old Style Aloe Toxin Rid page at TestClear, and our Aloe Toxin Rid review and how-to-use guide covers its directions, schedules and limits in detail. For a wider comparison of products, see our Aloe Toxin Rid alternatives page.

Why a single wash faces such a steep climb

Think about where the drug sits. Hair is made of tightly packed keratin, with an outer cuticle that overlaps like roof tiles. Compounds deposited from the bloodstream are spread through the interior of the strand and bound to pigment and protein. A 20-minute lather mostly reaches the surface and the outer cuticle. That's why the products that people describe most seriously all involve either many long washes or harsher chemistry, and why even those lack published proof.

Body hair claim

The label says the shampoo can be used on all body hair. That's relevant because collectors switch to chest, leg or underarm hair when head hair is too short, and body hair can hold a much longer history than the roughly 90 days covered by a standard head-hair sample. Applying any shampoo to body hair raises the same evidence problem, and you'd need to be careful with sensitive skin. Nothing on the label suggests it changes the length of history body hair holds.

Drug-by-drug realism

• Cannabis: THC metabolite enters hair in very small amounts, so light users often test negative on hair regardless of products. Heavy daily users usually test positive.
• Cocaine and meth: both bind strongly to hair at higher concentrations, which makes any shampoo's job harder. See our page on hair tests after cocaine use.
• Opioids and benzodiazepines: detectable in hair, and prescriptions are the legitimate explanation; tell the medical review officer.

Safety and scalp care

Detox shampoos tend to be harsh clarifiers. Expect dryness, and stop if your scalp burns, blisters or breaks out. Keep the product out of your eyes. Some people stack this kind of shampoo with homemade routines like the Macujo or Jerry G methods, which add vinegar, salicylic acid, detergent and sometimes bleach. If you go down that road, never mix bleach with vinegar, acids, ammonia or household cleaners, since that can release toxic gas, and rinse with plenty of cool water if anything stings. Our Macujo method reviews page explains those steps and risks factually.

Buying it: what to check

• Name and packaging: older "Hair Follicle Cleanser" bottles and newer "Folli-Cleanse" bottles both circulate. Check the seller and expiry if listed.
• Marketplace listings: third-party sellers vary widely in storage and age of stock.
• Price per use: a single 2 oz bottle is cheap up front, but it's one session; compare against what you'd spend on a full routine.
• Directions on the bottle: follow those over any listing copy, since contact times differ between versions.

A better first move: test your own hair

Before spending on any shampoo, a mail-in home hair test tells you whether you're likely to have a problem at all. You cut a small sample close to the scalp, send it to a lab and get a private result. Plenty of people who expected the worst find their levels were never above the cutoff, especially light cannabis users or those whose last use was a few months ago. And if it's positive, you've learned that without involving an employer.

Who should skip all of this

If your test is for a DOT, FAA, federal, military, court, probation or parole program, don't use any shampoo or routine to try to change the outcome. A sample that looks treated can be recorded as a refusal, which can carry consequences as serious as a positive. Talk to the program, an MRO, a treatment provider or a lawyer instead. And if you're pregnant, have a skin condition or a sensitive scalp, check with a doctor before using harsh clarifying products.

Our honest take

High Voltage's hair follicle cleanser is a small, inexpensive, single-session product with a label that promises a temporary effect. That's a modest pitch, and the evidence doesn't support anything bigger. If you're comparing it with Old Style Aloe Toxin Rid, the real differences are schedule, thoroughness and cost per routine, not proof, because neither has independent data showing it gets anyone below a lab cutoff. Time without use is the only factor that's certain to count, and a home hair test is the most useful money you can spend first.
