How to Identify Fake Kirkland Minoxidil

How to Spot Fake Kirkland Minoxidil:

Kirkland Minoxidil is one of the most counterfeited hair loss products in the world.

It isn’t licensed for sale outside the US, which means no Boots, no Superdrug, no official importer.
That gap is exactly where scammers thrive.

Who makes it?

It’s manufactured for Costco by Perrigo, the same global pharma group behind generic Regaine. Production runs come out of Canada and Israel — which is why you’ll see small differences in labels and packaging. Both are genuine.

Common Myths (Ignore These)

• Expiry date font colour: Some batches use white print, some use black, some are laser-stamped. All are real. Don’t rely on colour.
• Crystals in the liquid: White residue is just dried alcohol/water. Not proof of authenticity.
• Bleach tests: Internet nonsense. It ruins the product.
• Price alone: Cheap deals often mean grey imports dodging VAT and duty — or outright fakes. Genuine UK sellers have higher costs for a reason.

What Actually Matters

• Dropper: Real Kirkland droppers have a visible seam line from injection moulding. Fakes are smooth, flimsy, and wrong shape.
• Lot/Expiry codes: Genuine bottles have unique batch codes, either printed on each bottle. 
• Fakes will usually all show the same date, which is files in the future
• Liquid: Slightly yellow, mildly alcoholic, a little oily. Not watery, not perfume-heavy, and never completely odourless.

Why It’s Not in Boots

Kirkland isn’t junk — it’s basically Perrigo’s own-label Regaine. But it’s only sold via Costco, and since it isn’t licensed here, you won’t find it on the UK high street. That’s why who you buy from matters.

Proof We’re Genuine

We’ve used the same direct Costco supplier for over a decade. Our stock comes in original Costco cartons (see photos below), with full retail display packaging. No TikTok kids. No China warehouse mystery stock. Just the real thing, year after year.

Our Guarantee

In ten years, no customer has ever caught us out. But if Perrigo ever confirms we sold you a fake? You’ll get £1,000 on the spot.

Still Unsure?

Try a bottle. If it’s not what you expected, send it back within 14 days. No drama.
