Two months later, she started feeling strange with pain in her scalp and gums.

“Just everything was kind of irritated.”

Her head did feel better without the extensions, but she wasn’t completely back to normal.

Tricia Helfer experienced symptoms even after her metal clip-in hair extensions were out.

“When I was filming, I was having trouble remembering my lines.

I felt foggy, just general malaise.

I was sometimes kind of nauseous.

I’d walk up a flight of stairs and start huffing and puffing.

I just felt like I couldn’t remember things.”

She went to the doctor her friend had seen.

Her treatment plan included cortisone shots and chelation therapy.

They worked over time to decrease the amount of metal in her body and to grow her hair back.

Because those types of extensions are meant to stay in for three or four months at a time.

And that’s when the damage can happen."

Perhaps Helfer did have clip-ins but kept them in too long unknowingly.

With clip-in hair extensions, it’s recommended to take them out before you sleep or exercise.

You also shouldn’t shower in them.

Instead, remove them to wash them in a clean container or your sink.
