Beauty Hair Crimping Guide: Techniques, Volume Tricks and Tool Care
An educational guide from the Beauty AMZ research team. No hard sell, just what you need to know.
The volume secret
Crimping works by creating texture that pushes hair apart. Flat hair lies compressed; crimped hair has built-in lift. Crimping just the roots adds invisible volume. The under-layers support the smooth top. This is why stylists crimp before updos.
Retro vs modern crimping
80s crimping meant tiny zigzags over the whole head. Modern crimping uses larger plates for softer texture. Today's technique hides crimps under smooth hair. The goal is volume, not visible pattern. Update the classic for current style.
Heat safety essentials
Never crimp wet or damp hair; it boils the shaft. Heat protectant is non-negotiable. Test temperature on a tissue first. Keep the iron moving; do not park it. Let tools cool on a heat mat. Respect the heat and your hair survives.
Making texture last days
Start with day-old hair; too-clean hair slips. Cool each section before releasing. Set with light hairspray. Sleep on a silk pillowcase. Refresh roots with dry shampoo. These steps stretch crimps to day 3 or 4.
Tool maintenance
Wipe plates with a damp cloth when cool. Remove product buildup that causes sticking. Check cords for damage regularly. Store in a heat-proof pouch. Clean plates ensure even heating. A maintained tool performs like new for years.

Heat Styling on Toned Blonde: The Order That Protects Color
Crimping and purple shampoo interact in ways that surprise blondes: heat accelerates color fade, and purple shampoo plus heat is a combination that needs sequencing. The rule is tone first, heat second, never the reverse on the same day if you can avoid it. Freshly toned hair has pigment sitting near the cuticle surface, and running a hot tool over it bakes some of that pigment out while driving the rest deeper unevenly. If you must style the same day you tone, keep the tool temperature at the lowest effective setting and use a heat protectant, which slows pigment loss measurably. The deeper issue is that heat styling raises the cuticle over time, making hair more porous, and porous hair grabs purple pigment aggressively, which leads to the over-toning problem of dull, darkened blonde. Blondes who heat style regularly should tone less often than the label suggests, not more, because their porosity is doing part of the pigment-grabbing work already. A purple conditioner instead of a purple shampoo is often the better format for frequent heat stylers, since it tones more gently while delivering the moisture heat styling strips. Our Amika purple guide covers a toning line built with damage-prone blonde in mind.
Hard Water and Brass: Why Purple Shampoo Alone Fails
Some brass resists every purple shampoo, and the reason is rarely the shampoo: it is mineral buildup. Hard water deposits calcium, magnesium, and copper on the hair, and that mineral film both creates its own brassy cast and blocks purple pigment from reaching the hair underneath. No amount of toning fixes this because the pigment cannot get past the film. The diagnostic is simple: if purple shampoo worked for months and then stopped, or if brass appeared rapidly after moving to a new home, suspect minerals before blaming the product. The fix is a two-step routine: a chelating shampoo first to dissolve the mineral film, then the purple shampoo on the now-clean hair where it can actually work. Chelating once or twice monthly is enough for most hard-water households; more frequent use dries the hair unnecessarily. This is also why blondes in hard-water areas go through purple shampoo faster, using extra product to compensate for blocked absorption. A shower filter reduces the mineral load at the source, though results vary with water hardness. For the toning half of this routine once minerals are handled, our best purple shampoo guide helps match formula strength to your blonde.
