Find the part that cost somebody something.

Every drawer in this trade has been called snake oil at some point, and the honest answer is that nobody can tell by looking. Not you. Not us, about ours. Glass is glass, a dropper is a dropper, and a list of botanical oils prints exactly the same whether it is true or not.

So this page is not going to ask you to look harder at the bottle. It is going to ask you to find the one thing on it that somebody had to pay for.

What it is: A leave-in scalp oil. Eight botanical oils and a vitamin E.
Where it goes: On the scalp, not on the hair. Damp, after washing.
How often: Three to five times a week, with two or three minutes of massage.
Who it is for: Hair that is healthy now, and somebody who intends to keep it that way.

In everything else he buys, the part he pays attention to is the part somebody signs.
This one has a label on it too, and a nice bottle, and a list. None of that is the part that matters.

What a bottle shows you

Everything you can see was free to put there

Take the things a bottle actually shows a man, and put next to each one what it cost the person selling it.

The glass costs a few cents more than plastic. The dropper costs a little more than a cap. The color of the oil is the color of whatever is in it, and it can be adjusted.

The ingredient list costs nothing at all. It is a set of names, in an order, and printing a true one costs exactly what printing a false one costs.

The sentence on the front is a sentence. Sentences are free.

And the number, which people trust most of all, is the emptiest of them. It is typed into a field. It can go up on a Tuesday so the bottle looks serious and down on a Friday so it moves. Expensive proves nothing. It never did.

This bottle is not the exception to any of that. Ours is glass. Ours has a dropper. Ours prints a list of eight botanical oils and a vitamin E, and you have no way of checking a single word of it from where you are standing.

My wife noticed before I did, which is how I know it's working. She said I looked rested, and I've learned over the years that when she uses that word about my face, it's about the hair. I've been through a few products over the years that promised the world and delivered a brochure. This one just keeps doing its job.

The one line that is not free

A brochure is the part that was free to make. So the question was never what a brand is willing to say, because everyone is willing to say. The question is what a brand is still paying for after it turns out to be wrong.

There is one line on this bottle with a cost attached, and the cost is ours:

90 DAYS. IF IT DIDN'T WORK, THE MONEY COMES BACK. NOTHING GOES BACK TO US.

Read the second half of it, because that is where the money is. Nothing goes back to us. Not the bottle, not what is left in it. 90 days is long enough to use most of a 30 ml bottle, and if you tell us it did nothing for your hair, we do not ask for the rest of it back.

That is not a better argument than the ingredient list. It is a different kind of thing altogether. The list is a claim, and claims are printed. This one is an expense, and expenses are paid.

A man photographed from behind, the full dense head of dark hair he still has, damp and combed back, a white towel over one shoulder, no thinning at the crown, no face visible. — The test does not run on the label. It runs here, on a damp scalp, for 90 days.

Said flat

What you would actually be buying

None of the above says the oil is any good. Nothing written down can say that, which is the whole trouble. So here it is in the flattest language we have, and you can weigh it however you weigh things.

It goes on the scalp rather than on the hair. That is a fact about where it is applied, not a claim about what it does. Damp, after washing, two or three minutes of massage, three to five times a week. Eight botanical oils and a vitamin E: you can read that list on the bottle, and reading it will tell you exactly as much as reading anybody else's.

What you should be able to see by week four to six is shine, softness and body. Those three sit on the fibre and on the scalp's own oil, so they do not wait on anything slower. If they are not there, you have a claim to make, and you already know what happens next.

The only test with a price on it

Somebody pays for being wrong. Not you.

You have read this far without being asked to believe anything, which is the most an honest page can do from the outside of a bottle. The rest of it is not a reading problem and it never was.

A couple of drops on the scalp, three to five times a week, and four to six weeks before you bother looking. If the hair you keep does not have more shine, more softness and better body by then, the 90 days is sitting there, and it is ours to pay.

Get the bottle

And one small thing for tonight, which costs nothing and does not involve us. Whatever bottle is already open in your cabinet: go and find out what its seller has agreed to pay if it does nothing at all. The answer is usually very short. It is also the only part of a bottle you can genuinely read from the outside.
