About Heat Index
An independent publication about hair dryers, straighteners, curling irons, blow-dry brushes and grooming devices - organized by hair type instead of by brand.
What this is
Heat Index covers heat styling tools and grooming devices. It currently has 67 content pages and 36 products with cited specifications, and it is organized around one structural decision: you can navigate it by hair type as well as by product category.
That sounds small and it is the whole idea. Every competing site in this category sorts by product, and hair type appears at best as a heading buried inside a roundup. But nobody knows they need a 1,875W AC-motor dryer. They know their hair is fine and goes flat, or thick and takes forty minutes to dry, or bleached and breaking. Starting there produces a different site.
Who writes it
Scooter M. — an enthusiast who's genuinely into this. I read the manuals, compile the published specs and do the math. No lab coat.
That is deliberately not a credential, because I do not have one. I am not a cosmetologist, a trichologist or a dermatologist, and nothing on this site should be read as medical advice. What I am is someone who found the existing coverage of this category frustrating in a specific way: it is full of opinions and empty of numbers, and the numbers are mostly published and mostly ignored.
Who it is for
Someone upgrading rather than buying their first tool, who already knows roughly what their hair does and wants to know which specification actually matters for it. And anyone dealing with frizz, breakage or heat damage who has read a lot of vague advice and would like a number.
- If you want the temperature question answered with sources, start at the flat iron temperature chart.
- If you want to know what any of this costs to run, that arithmetic is in the wattage guide.
- If you just want to be told what to buy, pick your hair type and the site will route you.
What this site will never do
- Claim to have tested something it has not. This is the line that matters most and it is not negotiable.
- Publish a fabricated review or testimonial. There are no customer reviews on this site because there are no customers. An honest absence beats an invented endorsement.
- Invent a credential. No expert panel, no medically-reviewed-by, no years of experience I do not have.
- Quote a price from memory. Prices come from a live layer or the page says "check price". Never a stale number.
- Take money for a placement. See the disclosure for exactly how this is funded.
- Link a product that does not exist. Every buy link resolves to a real listing, and where a product has no verified listing the link is a tagged search rather than a guessed one.
How new this is
Heat Index published its first pages on 2026-09-07. It has no history, no archive and no accumulated authority, and pretending otherwise would be the first broken promise on the list above. What it has instead is a method you can check and sources you can open.
Publisher and contact
Heat Index is published by Slate Mill Group. There is no office to visit and no phone line — this is a publication rather than a business with premises, and listing an address would be inventing one.
