The Follicle Field Guide
The companion guide to the Health Reset hair-loss channel One payment. No subscription. · Educational material only.
Three guides · one free sheet

Our Complete Library

Every guide here answers one question, so you can take the book that solves what you are dealing with today — which kind of hair loss this is, or which of the treatments people keep telling you to try has evidence behind it. Or take the complete set, and walk into your next appointment with paper instead of a story.

One payment each. PDFs by email. No subscription, no renewal, no account, and no card kept on file. Every statement of fact inside carries its source and its year on the page where it appears.

Educational material only. Not medical advice, not a diagnosis, and not a substitute for care from a licensed clinician. Nothing here promises a single hair.

Some kinds of hair loss should be looked at promptly, not treated at home.

Loss that came on over days rather than years. Hair coming out in round or oval patches, or in the beard, eyebrows or eyelashes. Skin in the thinning area that itches, burns, hurts, is scaly or red, or looks smooth and shiny with no visible pores. Hair loss alongside unexplained fatigue, weight change, joint pain, a rash or fever. Shedding during pregnancy or after a birth. A medication started, stopped or changed in the last few months.

The full list is printed on each guide's page, before any payment button — and it is the first page of the free Blood Work Sheet below, because in this subject that page is never behind a payment. If any of it describes you, ask for an appointment first. The guides will still be here afterwards, and they will be more useful to you once somebody has looked.

"Which kind of hair loss is this?"

The Follicle Field Guide

The naming book.

$27

224 pages · fourteen chapters · four appendices

  • The differential table that sorts five families of hair loss by speed, distribution, symptoms, whether the follicular openings are still there, and how urgently each one needs to be seen (Chapter 4).
  • The medication classes documented in the drug-induced alopecia literature, and the one sentence to put to whoever wrote the prescription — because nobody stops a medication because of a book (Chapter 9).
  • The blood work, with both sides of the ferritin dispute printed with their sample sizes and their years, and the test names written exactly as a US lab orders them (Chapter 11 and Appendix B).
  • Appendix C: every claim we went looking for and could not confirm, printed instead of guessed.

"Of everything people tell me to try, which has evidence — and what does each cost me in a year?"

The Follicle Field Guide to Treatments

The referee.

$47

277 pages · sixteen chapters · four appendices

If you still do not know which kind of hair loss you have, this is not the book to start with. Weighing treatments before anything has been named is how the last two years went.

  • The over-the-counter minoxidil Drug Facts label read line by line, including the four of its own "do not use" statements that describe a large part of this audience (Chapter 3).
  • Finasteride, dutasteride, the blood-pressure pill and spironolactone, each in the words of its own label — and why the reassuring safety numbers are not about every reader (Chapters 4 to 7).
  • What the 2015 rosemary oil trial actually found, printed straight, and then its four limitations printed just as straight (Chapter 10).
  • Devices and procedures with what each costs and what the evidence shows, plus menopause — what is established, and what is not (Chapters 11 and 14).

"I have an appointment. How do I make it produce an answer?"

The Follicle Field Kit

Both books, plus the paper you take out of the house.

$97

Both guides plus 13 printable sheets — 224 + 277 + 82, so 583 printed pages in all

  • Both guides in full, at 224 and 277 pages, plus the printable set: 13 sheets, 82 pages, sized for US Letter and laid out to print on a plain home printer in black ink alone.
  • Six of the thirteen sheets are not in either guide: what it costs and who pays; what to do with the months while you wait; how to photograph the back of your own head; how to start again after stopping; how to cover it up honestly, with prices and their dates; and one for the person reading this on somebody else's behalf.
  • The other seven are the paper the books ask you to bring: the lab-request and results sheet with the disputed thresholds printed on it, the medication cross-reference for your prescriber, the twelve-month record with its photo protocol, the ten-minute appointment script, the supplement stop list, the warning-signs page for the fridge, and the source index with the FDA label setids.
  • The arithmetic, in words and with no crossed-out price: bought separately at their own checkouts the two guides are $74; the Kit is $97, so the printable set costs $23. We are not going to invent a "value" for paper we do not sell on its own.

The Blood Work Sheet

10 pages · free, for your email

Get it free

We recommend the Kit for a specific reason, not because it costs the most: the thing nobody can sell you is the answer to which kind of loss you have — only a clinician who examines you and orders blood work can name it. What the Kit does is make that appointment produce the answer, which is the one thing a twenty-minute video physically cannot hand over. If you are not there yet, $27 answers the first question and this page is not going anywhere.

Prices are one-time payments in US dollars. Nothing on this page renews.

The Blood Work Sheet — 10 pages. The tests to ask for, the words to use, and the warning signs that mean don't wait.

What is on the ten pages:

  • The warning-signs page in full, first, before anything else — because in this subject that page is never behind a payment.
  • The test list written exactly as a US lab orders it — CBC with differential, ferritin serum, iron and TIBC, and TSH with reflex to Free T4 — each with one line of why, and its source named on the page (StatPearls, NCBI Bookshelf NBK430924).
  • Why the list stops there, which is the part no free video gives you: vitamin D, zinc and B12 get suggested constantly and each one comes with its own argument about where "low" actually sits. A longer list is what turns a ten-minute appointment into a negotiation about tests — and the published limit is printed alongside: with no risk factors, further laboratory evaluation is not warranted (Guo and Katta, 2017).
  • The sentence to say out loud, word for word, so nobody has to improvise while the clock runs. It is built to fit in the first thirty seconds.
  • The line that makes it worth keeping: ask for the number, not the word "normal" — your report calls ferritin normal above roughly 12 to 15 ng/mL, because that cut-off was set to catch anemia, and whether the level that matters for hair is higher is genuinely unsettled.
  • The three ways this goes wrong, including the one that can do real harm: nobody starts iron on their own.

We will email you the PDF, and a handful of follow-up emails over the next couple of weeks. One click unsubscribes you, and we do not sell or share your address. By entering your email you are asking us to send you those emails. Educational material only — not medical advice. See our Privacy Policy.

What it does not do: it does not interpret your results, and it does not weigh a single treatment. Nothing on it tells you what to do with a ferritin of 31 or a TSH of 3.8, and nothing on it tells you to take iron — starting iron on a hunch is the most harmful thing anyone could do with this page. It gets you the numbers. The numbers do not tell you which kind of loss you have.

Where these came from

These guides are the companion material to the Health Reset hair-loss channel — the version you can print, write on, and hand to somebody across a desk.

They are not transcripts of the videos and they are not a course. They are the sourced version: every statement of fact printed with the study, the label or the guideline it came from and the year it was published, so you can check any line without leaving your chair, and so can your clinician.

Eight straight answers

Questions people ask before buying

Why should I believe any of this?

You should not, on our word. That is the whole design. Every statement of fact in both guides carries its source and its year on the page where it appears — the FDA-approved label with its setid, the journal with its issue, the American Academy of Dermatology page, the NCBI Bookshelf entry — so you can check any line without leaving your chair, and so can your clinician. Where the research disagrees, both sides are printed with their sample sizes. And both books carry Appendix C: What We Could Not Verify — the list of things we went looking for, could not confirm in a primary source, and therefore did not print as fact. Nobody in this subject publishes that list. It is there because it is the only honest way to tell you that everything else was confirmed.

Does this contradict what the videos say?

Sometimes it adds the part a video cannot fit, and sometimes that qualifies a headline. That is not a disagreement, it is a different job. A video has to hold your attention for twenty minutes; a page has to survive being checked. So where a topic is popular and the evidence behind it is thinner than the topic suggests, the guide prints the study, its size, its year and its limitations, and lets you weigh it. The rosemary oil chapter is the clearest example: the trial is real and it is printed straight, and then the four things that trial cannot tell you are printed just as straight. Nothing here asks you to stop watching. It asks you to have the sourced version in your hand when you are deciding where your money goes.

Is this a subscription?

No. One payment, one time. There is no renewal, no membership, no account to cancel and no card kept on file for later. You buy a PDF and it is yours. This is worth saying plainly because nearly every alternative in this subject is billed monthly, and several of them are billed monthly forever.

I'm a woman. Is this written for me?

Yes, and not as an afterthought. A widening part with the front hairline preserved is one of the five families in Chapter 4. Chapter 3 covers the triggers that get missed in women — a hysterectomy, childbirth, rapid weight loss, coming off birth control. Chapter 11 covers ferritin, which is the dispute women get the worst of. The Treatments guide devotes Chapter 7 to spironolactone and why the reassuring safety figures come from cohorts of women aged 18 to 45 with acne rather than from women over 60, and Chapter 14 to menopause, which is the largest unserved question in this market. One note that catches people out: the over-the-counter minoxidil men's solution says on its own label that it is for use by men only, and the label also says not to use it if your hair loss is at the front of the scalp. That is the product's restriction, not this guide's.

I'm already using minoxidil. Is this still any use?

Yes, and it will not tell you to stop. This guide gives no doses and no instruction to start, stop, change or adjust anything — that decision belongs to you and a clinician. What it gives you is the label read line by line, including what it says about how long before results can be judged and what happens if you stop; the chapter on how these things are actually used — frequency, contact time, what comes off on the pillow, and why starting two treatments in the same week makes both of them unreadable; the side effects that turn up in the first weeks, including the shed that follows any new stimulation; and Chapter 15, which is how to measure twelve months so that a treatment that worked is not abandoned at week three and a treatment that failed is not carried for two years.

I'm 63 and I've had this for twenty years. Is it too late for this to be worth anything?

We are not going to answer that with encouragement, because the honest answer is more useful. A miniaturized follicle is smaller and still there. A scarred follicle has been replaced by fibrous tissue, and dermatology reviews are blunt that this loss is permanent. Nobody — not us, not a photograph, not a mirror — can tell you which one you are looking at; that takes an examination. What Chapter 8 does is explain what the difference actually depends on and what would mean being seen soon rather than buying something. And there is a second reason this is worth doing at any age: several of the causes in Chapter 9 and Chapter 11 are things that matter for reasons that have nothing to do with hair.

What exactly do I get, and how?

PDFs, by email, within a couple of minutes of paying, plus a download link on the page you land on. The Field Guide is 224 pages, the Treatments guide is 277, and the Kit is both of those plus 13 printable sheets, 82 pages, sized for US Letter and laid out to print on a plain home printer in black ink alone. They read on a phone, a tablet or a computer, and the sheets are meant to be printed and written on. No app, no login, no shipping. If anything does not arrive, write to us and we will send it.

What if it doesn't help me?

Then write to us within 60 days and we will refund you in full. That is The Source-Check Promise, and it covers three separate things: a factual claim you find with no source behind it; finishing the guide and feeling it did not help you narrow down what is likely going on; or walking into an appointment no better prepared than you were before. What is deliberately not promised is a single hair — no book can promise that, and the ones that do are selling you something.
