🔍 What makes a flat iron truly professional?

It’s not enough that it’s “pretty” or “expensive”. A true professional flat iron must:

✅ Reach and maintain a constant, controlled temperature
✅ Be gentle on the hair fiber, even at 180–210°C
✅ Use materials such as ceramic, titanium or steam technology
✅ Have excellent glide, without snags
✅ Adapt to the hair type: fine, coarse, frizzy or treated
