Does Semaglutide Cause Hair Loss? Complete Guide

Does Semaglutide Cause Hair Loss

Semaglutide has become popular as a great treatment for diabetes, but some people are worried about its potential side effects, especially hair loss.

If you’re a diabetes patient or considering using Semaglutide it’s important to understand the facts before making any decisions.

In this article, we’ll discuss the connection between Semaglutide and hair loss, explore the research and studies conducted, and give some tips on managing hair loss while taking Semaglutide.

Things To Know About Semaglutide

Semaglutide is a type of medication that belongs to a group called glucagon-like peptide-1 receptor agonists, or GLP-1 RAs. It acts like the GLP-1 hormone that your gut releases after a meal, helping to control blood sugar levels.

Semaglutide helps your body make more insulin when necessary, reduces sugar production by the liver, and slows down digestion.

Additionally, because of its effects on appetite regulation, it has also been approved for use in weight management for people with obesity or overweight.

It comes in injectable and oral forms. It helps with blood sugar, but watch out for side effects like feeling sick, headaches, and maybe losing hair.

Note, if you take too much GLP-1, it can interact with the brain parts that control appetite and fullness. When combined with diet and exercise, it can lead to significant weight loss and a lower risk of cancer, diabetes, and heart disease for people who are obese or overweight.

Uses of Semaglutide

Semaglutide is primarily used to manage two major health conditions:

  • Type 2 Diabetes:It helps control blood sugar in adults by telling the pancreas to release insulin when blood sugar is high. It’s often prescribed with diet and exercise.
  • Obesity and Overweight Management:It is used for helping adults manage their weight in the long term. It’s for people with a BMI of 30 or higher, or 27 or higher with at least one weight-related ailment like high blood pressure or type 2 diabetes. This is done alongside eating less and exercising more.

In both situations, it’s important to follow the doctor’s advice carefully and tell a healthcare provider about any strange side effects.

What are the side effects of taking Semaglutide?

Semaglutide may have different side effects, some not so bad and some more serious.

Common side effects include:

  • Nausea and vomiting
  • Diarrhea
  • Stomach pain
  • Constipation
  • Headaches
  • Loss of appetite
  • Low blood sugar (especially if you take other diabetes medicines)

Some serious side effects that have been reported include:

  • Pancreatitis (inflammation of the pancreas)
  • Gallbladder problems
  • Allergic reactions
  • Kidney problems
  • Thyroid tumors in animal studies (more research is needed to determine if this applies to humans as well)

Connection between Semaglutide and hair loss

Does Semaglutide Cause Hair Loss

There is no evidence directly linking Semaglutide to hair loss but some patients have reported this side effect.

Hair loss is more likely because of stress and changes in nutrition caused by the better control of appetite and weight loss effects of Semaglutide. This can cause temporary hair shedding over several months, a condition called telogen effluvium.

However, it’s important to note that hair loss can also be caused by other factors like genetics, underlying medical conditions, or medication interactions.

Does Semaglutide cause hair loss? The Research

Yes, semaglutide may cause hair loss. Some people may notice hair loss when taking semaglutide medications like Ozempic, Wegovy, Mounjaro, or Zepbound after rapid weight loss. But, it doesn’t appear to happen frequently or be permanent. Not everyone will have this side effect.

However, the FDA is looking into cases of adverse events, like hair loss, suicidal thoughts, and aspiration, reported through its FDA Adverse Event Reporting System (FAERS).

The FDA is also investigating hair loss, medically known as alopecia, as a side effect of GLP-1 medication.

Dr. Mir Ali, a weight loss surgeon, said he wasn’t surprised to hear that GLP-1 drugs can cause hair loss.

Dr. Lydia C. Alexander, chief medical officer for Enara Health and president-elect of the Obesity Medicine Association, said that the main reasons for hair loss during obesity treatment are quick weight loss and not getting enough vitamins and minerals.

In summary, GLP-1 medications can lead to significant and rapid weight loss, similar to very low-calorie diets. Therefore, it’s not uncommon to observe increased instances of hair loss. Based on our experience, hair typically regrows 3 to 6 months after weight stabilization, with the support of nutrient replacement and nutritional counseling.

If you’re losing hair while taking Semaglutide, talk to your doctor immediately. However, more research is needed to fully understand the link between Semaglutide and hair loss.

How long does Semaglutide cause hair loss?

While the exact duration of hair loss associated with Semaglutide is not well-documented, it often aligns with periods of rapid weight loss. Once weight stabilizes, hair regrowth typically begins.

This process can take anywhere from 3 to 6 months post-weight stabilization, according to healthcare professionals.

Patients must receive proper guidance on nutrition to ensure that their bodies receive the necessary vitamins and minerals during this time, which can significantly aid the recovery process.

Is hair loss with Semaglutide permanent? Will I go bald?

No, you will not go bald. The good news is that hair loss or shedding is usually just a temporary side effect of rapid weight loss with these semaglutide medicines. It’s not very common and it only affects less than 5% of people based on clinical data, and usually only impacts the hair on the scalp.

Many people notice their hair thinning and shedding more in the hairbrush, rather than resulting in a bald spot. Hair may come out when shampooing or brushing, but not in clumps.

Once your weight stabilizes and you continue to take Semaglutide, your hair should grow back. If it does not, consult with your doctor as there may be other underlying factors causing the hair loss.

What do the studies and research say?

Here are some research studies that have looked into the effect of semaglutide on hair loss:

In studies of Wegovy (semaglutide), 3% of adults using Wegovy and 1% using a placebo reported hair loss. In children 12 years and older, hair loss was reported in 4% vs. 0% using a placebo. These were not considered common side effects, occurring in less than 5% of people.

Hair loss was not observed as a side effect in clinical trials of Ozempic (a 2-mg/wk injection) for type 2 diabetes.

However, in a trial of tirzepatide for weight loss in obesity, 5.7% of patients receiving the highest dose (a 15-mg once-weekly injection) reported alopecia, compared to 1% of those who received a placebo.

On the other hand, an analysis of 18 mainly observational studies found that 57% of patients experienced hair loss after bariatric surgery.

How to stop hair loss from Semaglutide?

To effectively deal with and possibly prevent hair loss linked to Semaglutide use, it’s important to talk to healthcare professionals. They can help patients with personalized treatment plans. These plans may include the following steps:

  1. Nutritional Assessment: A registered dietitian can offer a complete nutritional evaluation to ensure patients are obtaining necessary nutrients that support hair growth, like protein, iron, zinc, and vitamins A, C, and E.
  2. Monitoring Weight Loss Pace: Doctors may advise on adjusting the rate of weight loss to reduce the chances of hair loss. Slower, more stable weight loss may mitigate the shock to the body’s system, which is often associated with hair shedding.
  3. Stress Management: Since stress can contribute to hair loss, patients may benefit from stress-reduction techniques like meditation, yoga, or counseling, which could be facilitated by mental health professionals.
  4. Medication Review: It is important to explore whether other medications or health conditions might be contributing to hair loss. An endocrinologist or primary care physician can review current medications and check for hormonal or metabolic conditions.

For those experiencing hair loss while on Semaglutide, these measures, along with sustained medical support, often lead to the reversal of hair shedding.


In conclusion, while Semaglutide is linked with hair loss in some people, this side effect is temporary and manageable. Good nutrition, managing stress, and talking to your doctor can help stop and reverse hair loss. It’s important to take care of your overall health while using Semaglutide for weight loss, without causing long-term harm to your hair.
