An entry in the Record

Regaine and Rogaine: one molecule, two national labels

The active ingredient is minoxidil in both. What differs is which country's licence you are standing inside, and that turns out to matter more than the spelling.

Why there are two names

Because a brand is registered country by country, and so is the licence underneath it. In the UK the licensed products are Regaine. In the United States the labels are Rogaine. The molecule in both is minoxidil.

The UK side is on the public record. Regaine for Men Extra Strength Scalp Solution 5% w/v holds marketing authorisation PL 15513/0365, in the name of McNeil Products Limited, and is indicated for the treatment of alopecia androgenetica in men. The matching foam — Regaine for Men Extra Strength Scalp Foam 5% w/w — is PL 15513/0366, indicated for the treatment of male pattern baldness. Both carry the legal category General Sales List. Read from the electronic medicines compendium on 24 September 2026.

Search the United States National Library of Medicine's DailyMed database and the corresponding products come back under the name ROGAINE — "MENS ROGAINE EXTRA STRENGTH UNSCENTED", "WOMENS ROGAINE UNSCENTED" and so on, with minoxidil as the active ingredient and Kenvue Brands LLC as packager.

Same drug, two regulatory records, two sets of words on the box.

What "the same" does and does not cover

The active ingredient is the same, and that is the claim this page will make. It will not go further and say the two products are identical, because that is a claim about excipients, concentration by weight or volume, presentation and labelling, and it would require reading both full records side by side and finding them to match. The UK solution's own record, for instance, lists minoxidil 50 mg/ml along with propylene glycol 500 mg/ml and ethanol 280.53 mg/ml — a formulation detail that matters to anyone whose scalp objects to one of them.

So: if the question is "is the active the same", yes. If the question is "can I treat a box bought in one country as interchangeable with the box licensed in the other", that is a different question and the honest answer is that they are separately authorised products and you would need to read both labels.

The thing an imported box quietly costs you

You are buying a product licensed by another country's regulator, under another country's rules, with that regulator's label. What you leave behind is not glamorous but it is real.

The UK licence is the document that governs what may be sold to you here and what the seller must tell you. The UK pharmacovigilance system — the Yellow Card scheme — is where a UK user's suspected side effect is reported and counted. Recourse against a UK seller is a UK matter. None of that travels with a box bought from an overseas listing, and if the product arrives without the UK label you are also, in the plainest sense, reading the wrong instructions.

Price is usually the motive, and it is worth noticing that the UK product is already general sale. General Sales List means a shop may sell it without a pharmacist involved — there is no gatekeeper here to route around, which removes most of the argument for importing in the first place.

What the UK licence rules out

The Regaine for Men Extra Strength solution record is specific about who it is not for, and the exclusions are more useful than most of the marketing around the category. It is not for women, nor for people under 18 or over 65, on the grounds that safety and effectiveness have not been established in those groups.

It also says not to use it where there is no family history of hair loss, where the hair loss is sudden or patchy, where it follows childbirth, or where the cause is unknown.

Read that list again as a diagnostic checklist rather than a legal disclaimer. Sudden loss, patchy loss, loss after a birth or an illness, loss you cannot explain — each of those is a reason to be examined, and the label is telling you so on behalf of a regulator with no product to sell. There is a separate UK product range licensed for women; the point of the exclusion is that the men's licence is the men's licence.

"Extra strength", and what the number means

The 5% in the name is a concentration, which is a statement about the product rather than a promise about the outcome, and the UK licence does not convert it into one. This site prints no guidance on which strength or format anybody should use, and no instruction on how to use either: those are on the carton in your hand and in a pharmacist's answer, not on a reference page.

What the licence does establish is that both the solution and the foam are, in this country, general sale, and both name androgenetic hair loss in men as what they are for. That is the whole of the UK legal claim.

Where each one sits on the shelf

In UK terms there are three positions and Regaine occupies the nearest one. It is general sale. Finasteride 1 mg tablets are prescription only. Minoxidil 5 mg tablets are prescription only and licensed for severe hypertension, which is a different illness entirely — the subject of oral minoxidil in the UK.

The three side by side, with their licence numbers and legal categories, are in what is licensed for hair loss in the UK. And if the hair loss you are describing is one of the kinds the Regaine label tells you not to treat with it, the free step comes first: what the NHS does and does not fund explains why the diagnosis is the part worth having. If the question has moved on to surgery, who may lawfully carry it out is set out on hair transplants in the UK.

Regaine and Rogaine, answered

Are Regaine and Rogaine the same thing?

They share an active ingredient — minoxidil — and they are separately authorised products in two countries. Regaine is the UK-licensed brand, with marketing authorisations PL 15513/0365 for the 5% solution and PL 15513/0366 for the 5% foam, both held by McNeil Products Limited. ROGAINE is the name on the US labels held at DailyMed. Same molecule, two records.

Can I buy Rogaine in the UK?

The product licensed and sold here is Regaine. Buying an imported box means buying under another country's licence and label, outside the UK's own reporting and recourse arrangements — and since Regaine is General Sales List in the UK, there is no prescription gatekeeper to avoid by importing.

Do I need a prescription for Regaine?

No. Both the Regaine for Men Extra Strength 5% solution and the 5% foam carry the legal category General Sales List, which means a shop may sell them without a pharmacist involved. That is a statement about who may sell it, not about whether it suits any particular person.

Who does the Regaine for Men licence say it is not for?

Women, and people under 18 or over 65, on the basis that safety and effectiveness have not been established in those groups. It also says not to use it where there is no family history of hair loss, where the loss is sudden or patchy, where it follows childbirth, or where the cause is unknown.

Is the 5% version stronger in a meaningful way?

5% is a concentration, and the UK licence does not turn a concentration into a promise about results. This site gives no view on which format or strength anyone should use — that belongs to the carton and to a pharmacist, not to a reference page.

The whole question of who may lawfully operate in this country, and what the four registers actually show, is set out on hair transplants in the UK.
