Science says that you experience more hair loss after surgery. Noticing large amounts of hair shedding might cause you to fret, but there is nothing to panic about. Losing hair after surgery is a normal but common side effect called telogen effluvium. This is your body’s way of coping with undergoing a medical operation, and your hair should start growing back within a few months.

Surgeries can be traumatic to the body. They may stress you out and cause hair loss. Here, we discuss all the causes of post-surgical hair loss and if it can be reversed. Keep reading.

Hair Loss After Surgery: Is There Any Link?

Yes, surgery can cause temporary hair loss or telogen effluvium. After a major surgery, the body experiences tremendous stress. This may interfere with the hair growth cycle and cause hair loss or thinning (1).

Hair loss is often common in people who have undergone bariatric or gastric sleeve surgeryi  A surgical procedure where part of the stomach is removed from the body while the remaining portion is formed into a tube-like structure. (2). Stress and nutritional deficiencies are believed to be the major reasons for such hair loss. Once these factors are addressed, hair loss stops (1).

The hair cycle is a complex biological process where the hair follicles undergo three major stages (1):

  • Anagen (growth phase lasting for 2-6 years)
  • Catagen (transitional phase lasting for 2-3 weeks)
  • Telogen (dormant phase lasting for about three months)

In the normal hair cycle, follicles on the scalp are replaced once every 3-5 years. However, during telogen effluvium, the hair follicles in the anagen or growth phase are triggered to enter the telogen phase prematurely (1). This causes hair thinning and shedding. What are these triggers? Find out below.

What Causes Hair Loss After Surgery?

Physiological stress is the major cause of hair loss after surgery (1). However, the exact mechanism is not clear. It is speculated that the body diverts all its resources (nutrients and energy) to keep the vital organs functioning, while less important functions, such as hair growth, are put on hold temporarily.

The surgical procedure followed by recovery puts the body under substantial physiological stress. It is widely believed that the anesthetics used during the surgery can trigger hair loss. However, there is no scientific data to back this claim.

Apart from the physiological process, the uncertainty involved and other psychological factors can take a toll on the mental health of the individual. Research indicates that stress can induce inflammatory effects that can inhibit hair growth, cause hair damage, and induce catagen (3).

The science behind how this happens is still in the nascent stages. It is speculated that stress acts as a trigger that signals the hair follicle to go dormant or enter telogen effluvium. Once your body starts to recover, the hair cycle normalizes. There are a few ways to speed up the recovery process and reduce postoperative complications that cause hair fall.

Marina Mogilko, a YouTuber, shares a personal experience with hair loss that occurred due to a leg length discrepancy and stress. Initially, the hair loss was attributed to seasonal shedding but became more severe. After exploring various treatments and vitamins, a doctor suggested that a previous stress-inducing surgery had caused this hair loss. She said, “I started thinking and I realized that in November I went through a surgery which wasn’t like a super huge surgery but it was invasive and I was put asleep for like an hour and that was very stressful for me mentally (i).”

How To Reverse Hair Loss After Surgery

You can reverse hair loss after surgery by removing the trigger events like stress, nutritional deficiencies (zinc and iron), and hormonal discrepancies (1).

According to a study conducted on 701 individuals and published in the Obesity Surgery Journal, patients who suffer from hair loss following metabolic and bariatric surgery have lower zinc concentrations. Approximately 57.0% of patients experience hair loss after MBS.

Thus, lifestyle changes, such as following a well-balanced diet and having a dedicated hair care routine can help you regrow your lost hair in 3-6 months.

You may take vitamin and mineral supplements like iron and zinc to reverse hair loss (4). This is especially helpful after bariatric or weight loss surgery. You may also consume amino acid supplements.

Generally, dermatologists recommend medication to stimulate hair growth if the hair follicle is still active. One such commonly prescribed drug for treating various hair disorders(telogen effluvium) is Minoxidil (5). or Rogaine.

Consult your doctor if the hair loss persists or worsens. It might indicate a serious medical condition. Here are a few more tips for managing hair loss after major surgery.
