Louis Theroux's Alopecia Bounces Back After Hitting Rock Bottom

Louis Theroux, aged 55, has reported a notable recovery from alopecia, an autoimmune disease he has battled since 2021. In a recent Instagram update, he revealed that his hair is showing regrowth, approximately one year after experiencing the most severe stage of hair loss in 2025. Theroux described the turnaround as surprising, as he made no specific interventions, took no drugs, and did not alter his diet or stress levels.

The documentary creator's alopecia began with his beard in 2021, followed by his eyebrows and patches on his scalp. He previously shared updates, including undergoing eyebrow tattooing in March 2024 after shaving them off due to patchy loss. He also mentioned exploring treatments like microblading. Theroux's latest update indicates a significant improvement, with regrowth visible on his scalp, sides, and even the back of his head.

Theroux's update comes shortly after the release of his documentary 'Inside The Manosphere,' which explored controversial male influencers. He had previously cautioned parents about the influence of these figures on young boys. His personal health journey with alopecia, while significant to him, is presented with perspective, acknowledging larger global issues but offering hope to those also affected by the condition.
