Heat Damage Basics

Today we’ll unlock the simple habits that stop heat damage and keep your hair shiny.

How heat affects hair

Imagine each strand as a rope wrapped in roof tiles. The tiles are the cuticle, the rope inside is keratin. Gentle heat reshapes temporary bonds, letting your hair hold a new style. Too much heat cracks and lifts those tiles, leaving the hair dull, rough, and prone to breakage.

Quick reminder

A sizzle is not a sign the iron is working. It's water boiling inside your hair.

Right heat settings

Your iron’s temperature should match your hair type. Fine or bleached hair does best at 150 to 170 degrees. Normal thickness handles 170 to 185. Very thick or tightly curled can go up to about 185 to 200, but keep it as low as possible.

Safe max temp

Keep your straightener at or below 180 degrees Celsius. Anything hotter just speeds up damage without any benefit.

Styling routine

After washing, gently squeeze with a towel, then let your hair air-dry for ten to fifteen minutes until it’s about seventy percent dry. Apply a coin-sized amount of heat protectant to the damp lengths. When you blow-dry, use medium heat, hold the nozzle fifteen to twenty centimeters away, and keep it moving.

Protectants work?

Protectant sprays leave a thin silicone film that spreads heat evenly and lets the plate glide. They don’t make a 230-degree iron safe, but they do reduce hot spots. A little serum on dry ends adds shine and tames frizz.

Signs of damage

Look for white dots or split tips along the shaft, a straw-like feel even after conditioner, curls that don’t spring back, and short broken pieces that stick out around the face. If you see these, trim and cut back on heat.

The one

The one habit that makes the biggest difference: use a single slow pass on completely dry hair, never exceed 180 degrees. This alone prevents bubble hair and keeps your strands smooth.
