Hair Straightener Mistakes: Fix Frizz Dents and Damage

If you’re using a hair straightener but still getting dents, frizz, or that “flat helmet” look, the problem usually isn’t the tool—it’s the routine. Below are the most common straightening mistakes and the fastest fixes, plus a simple comparison table to help you choose the best method for your goal.

Mistake #1: Straightening Hair That Isn’t Fully Dry

Hair can feel dry on the surface but still hold moisture inside, especially with waves or curls. Fix: dry fully, then wait a minute before you start. If you hear a faint sizzle, stop—hair isn’t fully dry.

Mistake #2: Taking Sections That Are Too Thick

Thick sections force you to repeat passes. Fix: cut your section width in half. One controlled pass beats three quick passes every time.

Mistake #3: Pausing Mid-Strand (Causes Dents)

Dents come from stopping, clamping too hard, or turning too sharply. Fix: steady speed and gentler wrist turns.

Mistake #4: Flattening Your Roots

When you iron too close to the scalp on the top layer, volume disappears. Fix: keep the top layer smoother and add hidden lift underneath using FIFN L01 Hair Crimper (Root Lifter).

How do I stop dents when straightening hair?

Keep a steady glide speed and avoid pausing mid-strand. Thinner sections help the most.
