The monograph

Outside the monograph

On this page11
The monograph is a narrow door with the answers written on it. Outside it there is no door.

Three ways out of it

An active the monograph does not name, a concentration outside the range it gives, or a claim about something other than dandruff, seborrheic dermatitis or psoriasis.

A new active is the clearest

The list at 358.710 is a list. A botanical extract with an anti-dandruff claim is not on it, however well it works, and being natural is not a route in.

A concentration above the range is still outside

Which surprises people. Pyrithione zinc at 3 percent in a wash-off product is above the 0.3 to 2 percent range and is outside the monograph, not a stronger version of it.

And below the range too

An active at a token concentration with a monograph claim is the same problem from the other side. The range is a range.

Hair loss is the commonest claim out

Growing hair, preventing loss or thickening follicles is not what this monograph covers. Where such a claim does belong is outside what this property can tell you.

So is scalp health as a therapeutic claim

Which is a phrase doing a lot of quiet work in this category. Saying a product soothes is different from saying it treats, and the line is drawn by the reader rather than the writer.

What outside the monograph means in practice

A new drug route, which is a different order of undertaking entirely, with evidence and a submission behind it. That is a regulatory project rather than a labeling decision.

Which is why most brands stay in

The monograph gives permitted actives, concentration ranges and the sentences to use. Designing a product to fit it is the cheapest route to a legitimate claim.

Or they make no treatment claim at all

A cosmetic conditioner that says nothing therapeutic is a cosmetic, with cosmetic obligations and no Drug Facts panel. That is also a strategy and it is the one most of this shelf serves.

The packaging reads the decision

A cosmetic can use a 2 oz double wall jar and a story. A monograph drug needs a label panel. Which one you are is the first question on the brief, not the last.

21 CFR 358.750, labeling. The statement of identity is "[Dandruff] (insert product form)" or "antidandruff (insert product form)", with the equivalent forms for seborrheic dermatitis and psoriasis. The indication is "(For relief of or Controls) the symptoms of" the condition. The general warnings are "For external use only" and "Avoid contact with the eyes. If contact occurs, rinse eyes thoroughly with water". Coal tar carries "Use caution in exposing skin to sunlight after applying this product. It may increase your tendency to sunburn for up to 24 hours". Both "If condition worsens or does not improve after regular use of this product as directed, consult a doctor" and "Do not use for prolonged periods without consulting a doctor" appear. Directions for a wash-off product are "For best results use at least twice a week or as directed by a doctor"; for a leave-on, "Apply to affected areas one to four times daily or as directed by a doctor". law.cornell.edu
Written from 21 CFR part 358 subpart H, 21 CFR 201.66 and the catalog as it stood on 18 October 2026. Whether a particular product is a cosmetic or a drug turns on its intended use, which is established by what you say about it; no page here can make that determination for you. Cosmetic labeling, facility registration and product listing are covered in the grooming property and not repeated.
