The short answer: Flakes is an anti-dandruff shampoo and conditioner set built around 2% pyrithione zinc — double the active ingredient of legacy dandruff brands, according to the company — in a sulfate-free, paraben-free formula with natural fragrance. Buyers report fast visible improvement in flakes and itch, often within days to weeks, and praise that it does not dry out their hair. But there is a serious caveat: multiple third-party reviews describe subscription orders that were paid for and never shipped, with dead tracking links and unhelpful automated support. This is a research-based review (no hands-on testing), compiled from the product’s stated specifications and buyer feedback.
Flakes was founded by Jason G. with dermatologist Dr. Bobby Buka as Chief Science Officer, and the brand positions itself as a dermatologist-designed upgrade over medicinal-smelling drugstore options. The shampoo uses cedar mint natural fragrance; the conditioner pairs yuzu basil scent with MCT oil for moisture. It is sold through the brand’s own site (byeflakes.com) and on Amazon.
In this review, I cover exactly what is in the bottles, what buyers consistently praise and complain about, the fulfillment red flags you should know before subscribing, and my final verdict.

Flakes Shampoo: Full Overview
The core of the Flakes formula is 2% pyrithione zinc, the well-established anti-dandruff active ingredient — at double the concentration the brand says legacy brands use. Pyrithione zinc targets the flaking and itching associated with dandruff, and a higher concentration is the brand’s main efficacy argument. The shampoo is built on a sulfate-free, paraben-free, PEG-free base, which matters because harsh sulfates can strip the scalp and worsen dryness for some people.
The conditioner is not an afterthought: it contains MCT oil for moisture and uses a yuzu basil natural fragrance, while the shampoo carries a cedar mint scent. Across buyer feedback, the scent is a genuine differentiator — woodsy and fresh rather than the medicinal smell people associate with dandruff shampoos. Both bottles are 9 fl oz (266 mL), and the set is designed to be used together.
The brand’s broader claims — dermatologist-designed and tested, with rapid results reported by brand-site reviewers — should be read carefully. Glowing timelines on a brand’s own site are anecdotes, not clinical outcomes, and the review pool there is brand-curated. That does not make the product bad, but it means independent buyer feedback (below) deserves real weight in your decision.
What Buyers Like
- Fast visible improvement. The most repeated praise: fewer flakes and calmer itching within days to weeks — including from buyers who say other dandruff brands had failed them.
- Does not dry out hair. Unlike some anti-dandruff shampoos that leave hair straw-like, buyers frequently say their hair feels soft and hydrated after the shampoo-plus-conditioner routine.
- Pleasant scent. The cedar mint shampoo and yuzu basil conditioner earn consistent compliments for smelling woodsy and fresh instead of medicinal.
- Works for women too. Despite marketing aimed at men, women buyers report it works just as well for them — dandruff does not discriminate, and neither does pyrithione zinc.
What Buyers Complain About
- Subscription fulfillment problems. This is the serious one: several third-party reviews report paid orders — including subscription renewals — that never shipped, dead tracking links, and support that felt automated and unhelpful. This is a buy-the-product concern, not a use-the-product concern, but it is significant.
- High price versus drugstore. Per ounce, Flakes costs notably more than legacy dandruff shampoos. The premium buys you higher active concentration and nicer formulation, but the gap is real.
- Marketing aimed at men. The branding leans masculine, which some buyers find off-putting or simply misleading, since the formula works regardless of gender.
- Hair goes greasy by day two (some). At least one buyer noted hair looking oily the second day — likely a function of the moisturizing conditioner and individual hair type.
Red Flags — Read Before You Buy
- Fulfillment risk is the headline caveat. The subscription-delivery complaints — paid orders never shipped, dead tracking, unhelpful automated support — are the most serious pattern in third-party feedback. If you try Flakes, consider a one-time Amazon purchase rather than the brand-site subscription until fulfillment proves reliable.
- Mind the sentiment gap. Independent Thingtesting reviews sit around 3.5 stars from a small pool (10 reviews), while the brand site shows 4.38 from roughly 1,600 brand-curated reviews. Neither number is the “true” rating; the gap itself is the signal — curated brand-site reviews skew positive.
- Gendered marketing can mislead. The ads target men, but pyrithione zinc works the same for everyone. Do not let the branding decide for you.
- See a dermatologist for severe cases. Persistent, severe, or worsening scalp issues — heavy scaling, sores, hair loss — deserve professional evaluation rather than another over-the-counter shampoo.
Verdict
As a formula, Flakes is genuinely compelling: 2% pyrithione zinc is a meaningful step up from standard drugstore concentrations, the sulfate-free base is kinder to dry scalps, and buyers consistently report fast, visible improvement without the medicinal smell or straw-like hair. If your main problem is flakes and itch that cheaper shampoos have not solved, the product itself earns its consideration.
But the buying experience is where caution belongs. The subscription fulfillment complaints are too consistent to ignore, and the wisest path is a one-time purchase — ideally via Amazon, where fulfillment and returns are Amazon’s problem, not a startup’s support queue. Skip the brand-site subscription until the company demonstrates reliable delivery.
Bottom line: a strong anti-dandruff formula undermined by fulfillment concerns. Buy it once, from a reliable seller, and judge the results on your own scalp — and see a dermatologist if your scalp issues are severe or persistent.
