How We Evaluate Hair-Growth Devices

We rank laser devices on wavelength, emitter count, treatment schedule and return policy. We publish no before-and-after photos, because they prove nothing.

myhair.health evaluates hair-growth devices against published clinical evidence and verified manufacturer data, and we are explicit about what we have and have not done ourselves. This page states our method plainly so you can judge how much weight to give anything we publish.

What we do

We evaluate every laser and red-light device on four criteria, chosen because they are what published trials and FDA filings actually track.

  1. Wavelength. Does the device emit in the evidence-backed red-light window, broadly 630-680 nm, with 650 nm the most commonly studied target? This is the mechanism, not a specification detail.
  2. Emitter count and distribution. How many light sources are there, what type are they, and how are they spread across the scalp? We are careful to distinguish pure laser diodes from mixed laser-and-LED counts, because manufacturers routinely present those as if they were the same number.
  3. Treatment schedule. How long is a session, how often is it required, and how realistic is that routine? Adherence, not hardware, is the most common reason laser therapy fails.
  4. Return policy. The published trials only begin showing measurable hair-count change around the four-to-six-month mark. A return window shorter than that is not a real trial period, and we weight it accordingly.

Where our numbers come from

Every price on this site is verified against the manufacturer’s own live product feed, not copied from another review site or from an outdated press release. When we say the iRestore Elite is $2,699 or the Theradome PRO LH80 is $995, we pulled that figure from the seller. Prices change, so we date-stamp our pricing pages and re-verify them.

Every clinical claim is tied to a published trial with its actual numbers. When we write that a helmet-type device produced a gain of 41.9 hairs per square centimetre against 0.72 in a sham group, that comes from a randomised, double-blind, sham-device-controlled study, and we tell you it was sham-controlled, because that is what makes the number worth anything.

What we do NOT do

We do not publish before-and-after photographs. A photo taken under different lighting, at a different angle, with different hair styling, six months apart, proves nothing, and the hair-loss industry knows it, which is why such photos are everywhere. We would rather show you a trial number with a confidence-inspiring study design than a flattering picture.

We do not invent hands-on testing we have not done. Where our analysis is based on published evidence and verified specifications rather than on months of personally wearing a device, we say so. Fabricating a testing narrative would be both dishonest and, for a site earning affiliate commission, a straightforward regulatory problem.

We do not publish ratings we cannot defend. You will not find invented star scores or aggregate ratings in our structured data. A rating implies a scoring process; where we have not run one, we do not fake one.

We do not accept free devices in exchange for coverage.

How we handle affiliate commission

myhair.health earns a commission when a reader buys through certain links on this site. We disclose that on every page that carries such a link, and the disclosure appears in our site footer.

The commission does not determine our recommendations, and the clearest proof is on the pages themselves. We publish the arithmetic showing every iRestore bundle saves you exactly zero dollars. We tell readers with an already-bald scalp to keep their money, because no device on this site will help them. We state plainly that the therapy shows nothing for four to six months. And we list the cheaper competitors, with their real prices, rather than hiding them.

On reviews: we quote real, published accounts with a link to the source, so you can read them in full and in context. We do not write testimonials, we do not pay for them, and we do not republish third-party aggregate star ratings, because a single number tells you nothing about whether a treatment suits your stage of hair loss.

We recommend iRestore where it wins on the evidence: it treats far more of the scalp than the budget devices, and it refunds the full price for twelve months, which is the only return window in this category long enough to cover the four to six months the therapy needs before anything is visible.

Corrections

If a price is wrong, a study is misrepresented, or a claim on this site does not hold up, we want to know and we will fix it. Reach us through our contact page.

What this site is not

myhair.health is an independent research and review site. It is not a medical practice, and nothing here is medical advice. Hair loss can have causes, thyroid disease, nutritional deficiency, autoimmune conditions, that no laser cap will address, and which need a doctor rather than a device. If your hair loss is sudden, patchy, or accompanied by other symptoms, see a physician before you buy anything.
