The Complete Handbook of Hair Color

This is exactly what I needed as a new salon owner trying to understand why our wholesale costs vary so much between suppliers and what we're actually paying for. Chapter 2 on specifications alone saved me hundreds in the first month—I finally understood why some products are priced 2x others and could make informed decisions. The troubleshooting chapter is solid too. My only gripe is that Chapter 6 could have more concrete examples of what markup is realistic and how to calculate it, but overall this is the reference I'll keep on my desk.

A refreshingly no-nonsense guide. After years of bouncing between beauty school theory and YouTube tutorials, I finally have something that explains the actual chemistry in a way that connects to what I do every day—why a certain developer volume matters, what happens if you mix the wrong ratio, how to spot a color failure before it's too late. The chapter on choosing the right product for different hair types and conditions is practical and specific. One small thing: some of the troubleshooting scenarios could use more visual reference (a photo of what 'hot roots' or 'uneven tone' actually looks like), but the text descriptions are clear enough.

Good fundamentals, but I was hoping for more depth on the newer plant-based and lower-ammonia formulations—that's where the category seems to be heading, and the book touches on it but doesn't drill into how those products actually perform differently or when to recommend one over traditional. The first chapter is solid and the troubleshooting is useful, but several chapters felt like a good overview rather than the complete handbook the title promises. Still worth having as a reference, just know it's an introduction to the category rather than a deep dive.

Solid reference, though I'm an educator and I was looking for more guidance on how to structure lessons around this material or how to explain color theory to students using real products. The book assumes you already have some baseline knowledge—it's not written for absolute beginners. That said, the business opportunity chapter and the technical specs breakdown are genuinely useful, and I'll be using the glossary and FAQ in my curriculum. Worth the price for that alone.

I picked this up as a distributor trying to understand product positioning better, and it helped me see the real differences between brands I carry. But I wish there was more on how to evaluate a new supplier's quality claims or what actual technical standards exist in the industry. The book is good at explaining what color is and how it works, but thinner on the industry standards, certifications, and benchmarks that matter when you're sourcing at scale. Still useful, just more foundational than I expected.

The chemistry explanations in Chapter 1 finally made sense of things I'd been doing by rote for years. Understanding why peroxide strength matters and what actually happens to the hair shaft was genuinely eye-opening. But honestly, the book feels incomplete without more visual aids—diagrams of the hair structure, a color wheel you can reference, photos of what different tones look like in real light. The text is clear, but a handbook without visuals is a bit limiting for a visual category like color. That said, the chapters on troubleshooting and maintenance are practical and I've already used the advice.
