How to Crimped Hair: Complete 2026 Guide to Perfect Beach Waves

A hair crimper is a heat styling tool equipped with two textured plates that press hair into alternating wave patterns, creating texture and volume from root to tip. Unlike a standard curling iron, which wraps hair around a barrel, a crimper applies direct heat and pressure to produce uniform, long-lasting waves — from tight zigzag crimps to loose, relaxed beach waves. The technique dates back to the 1970s disco era and has re-emerged as one of the most searched hair styling methods in 2026, with searches growing 47% year-over-year among women aged 18–35.

Whether you want tight retro waves or effortless beach waves, a quality hair crimper from FIFN combined with the right technique delivers salon-quality results in under 15 minutes at home. The key is matching your tool's temperature to your hair type and holding each section for the correct duration — typically 5–8 seconds per pass — to maximize hold without causing heat damage.

How to Crimped Hair in 5 Simple Steps (10–15 Minutes)

Follow this step-by-step guide to achieve beach-quality waves using the FIFN L01 Hair Crimper. This method works for all hair lengths above shoulder length and most hair types.

Hair Crimper Temperature Guide

Setting the correct temperature is the single most important factor in achieving great crimped waves without damaging your hair. Tourmaline ceramic plates — found in premium tools like the FIFN L01 — distribute heat more evenly than metal plates, reducing hot spots that cause breakage.

Do's and Don'ts of Hair Crimping

Pro Tips for Salon-Quality Beach Waves

1. Salt spray before crimping — Apply a sea salt spray to damp hair before crimping to create natural texture and extend wave longevity. Mix 1 tsp sea salt + 1 tsp leave-in conditioner + 100ml water for a DIY version, or browse FIFN styling products.
2. The overnight crimp hack — Apply large braids or loose rolls to damp hair before bed, crimp on the lowest heat setting (300°F) for 3 seconds per section, sleep on a silk pillow, and wake up to natural-looking waves with zero heat damage.
3. Mix crimper widths — Alternate between the L01 (1.25-inch) for body waves and the L05 Mini for face-framing pieces and short layers. This creates visual depth and prevents uniform-looking waves.
4. Reverse direction technique — Crimp every other section in the opposite direction (away from face vs. toward face) to create natural, tousled movement rather than uniform waves all falling the same way.
5. Cool-down matters — Allow crimped sections to cool for at least 2 minutes before applying any product or touching. Cooled hair sets faster, meaning waves last 2–3x longer throughout the day.

Frequently Asked Questions

How long do crimped hair waves last?

Crimped waves typically last 1–3 days depending on hair texture, humidity, and whether a setting product was used. On fine hair, waves may begin loosening after 6–8 hours. Using a sea salt spray or mousse before crimping and sleeping on a silk pillow can extend wave life to the full 3 days. The L01's tourmaline ceramic plates produce waves that set faster than standard metal crimpers, contributing to longer-lasting hold.

Is crimping hair bad for your hair?

When done correctly at appropriate temperatures (below 410°F) with a heat protectant, crimping is no more damaging than using a standard curling iron. The key risk factors are excessive temperature, repeat passes on the same strand, and skipping heat protection. Always use a quality heat protectant and limit weekly crimping sessions to 2–3 to maintain hair health. Tourmaline ceramic plates like those in the FIFN L01 reduce frizz and hotspots by up to 50% compared to basic metal crimpers.

What's the difference between a crimper and a waver?

A hair crimper has tightly spaced zigzag plates that create sharp, defined wave patterns — ideal for retro or textured styles. A hair waver (or beach wave tool) has wider, more rounded grooves that create loose, cascading waves similar to what salt water produces on naturally wavy hair. If you want tight, crimped texture, choose the FIFN L01 Hair Crimper. For relaxed, sun-kissed beach waves, a waver tool is the better choice.

Can you crimp short hair?

Yes, short hair above chin length can be crimped effectively. The FIFN L05 Mini with its 0.75-inch narrow plates is specifically designed for short hair, bangs, and detailed styling around the hairline. Work with smaller 0.5–1 inch sections for short hair to ensure even coverage and avoid stacking multiple passes on the same strand.

What temperature is best for crimping beach waves?

For loose, beach-style waves, 350°F–380°F (175°C–195°C) is the ideal temperature range for most hair types. This is hot enough to set the wave pattern firmly while remaining within the safe heat range for daily or near-daily styling. Start at 350°F, assess wave hold after 1–2 hours, and increase to 380°F only if the waves are not holding. The FIFN L01 crimper offers 5 precise temperature settings in 25°F increments for optimal control.
