Threading and Hepatitis: Understanding the Real Risk

A recent Instagram health reel by Dr. Aditij Dhamija went viral after claiming a case of liver failure linked to eyebrow threading. The doctor suggested that reused threading material caused micro-cuts, allowing Hepatitis B or C to enter the bloodstream. While threading itself doesn’t directly cause hepatitis, poor hygiene during the procedure could, in theory, pose a risk.

How Does Hepatitis (B & C) Usually Spread?

Hepatitis B and C are transmitted through direct blood-to-blood contact—typically via shared needles, unsterilized medical instruments, or contaminated blood products. Everyday cosmetic practices are generally low-risk unless they involve unsafe, unsterilized tools.

What Research Shows on Piercings and Similar Procedures

1. Body piercings have shown a modest increase in risk for hepatitis B and C infection overall, with odds ratios around 1.8 for both—meaning risk doubles in some cases—but this largely refers to non-hygienic or informal procedures.
2. Piercings and tattoos performed in unregulated or non-professional settings (like prisons or homes) carry a higher risk, while sterile, regulated parlors show no significant transmission linked to hepatitis.
3. Older research noted ear piercings and other cosmetic treatments (like shaving or manicuring) were occasionally associated with hepatitis, though risks have significantly declined with improved standards over time.
   
   

What Experts Say About Threading Specifically

Both internal medicine specialists and the medical community affirm: threading itself isn’t dangerous, but infection risk arises when sanitation is lax—especially if cuts are made and tools or threads are reused.

What People Are Saying (Anecdotal Insights)

• Reddit discussions generally reflect skepticism but advise caution—experienced users maintain that properly sterilized settings and tools bring risk down to nearly zero.
• Some individuals reported minor skin breaks or bumps post-threading, which—while common and usually benign—highlight the need for clean technique and safe aftercare.
• Notably, there is no credible evidence suggesting threading can cause hepatitis via saliva or respiratory droplets. Concerns about viruses like HPV or herpes are more plausible, but still very unlikely when done hygienically.

Bottom Line: How Risky Is It Really?

• Very low risk when threading is performed by licensed professionals using disposable thread, clean tools, and proper sterilization.
• Higher risk only exists if the tools are reused, hygiene is compromised, or threading is done at unregulated venues.
  
  
• Threading per se is safe, but it demands vigilance, like most cosmetic procedures, safety relies on the environment and protocols.

Tips for Safe Threading

1. Ask if disposable thread is used for each client.
2. Observe whether the technician wears gloves and cleans the skin area before starting.
3. Avoid threading if you have active sores or wounds near the brows.
4. Choose licensed, well-reviewed salons, especially in regulated areas.
5. Practice gentle aftercare (e.g., cleansing, avoiding harsh products) to prevent irritation.
