Understanding the Link Between Semaglutide Medications and Hair Loss

At Restore Hair Loss & Scalp Clinic, we’ve recently seen a rise in patients experiencing hair loss and thinning after starting medications from the Semaglutide class — including Ozempic. While these medications are effective for managing type 2 diabetes and promoting weight loss, many people are surprised to notice changes in their hair health during treatment.

Let’s explore why this happens, and what you can do to support your scalp and hair during your wellness journey.

Why Hair Loss Can Occur with Semaglutide Use

Semaglutide works by mimicking a hormone called GLP-1 (glucagon-like peptide-1), which helps regulate blood sugar and appetite. While this process supports weight management and metabolic health, it can also trigger side effects that indirectly impact hair growth.

The most common cause is a temporary condition known as telogen effluvium — a type of hair shedding that occurs when the body undergoes sudden changes or stress. Rapid weight loss, hormonal shifts, and nutrient deficiencies can all push more hairs than usual into the resting (shedding) phase of the hair growth cycle.

The Role of Nutrient Deficiency and Hormonal Shifts

When using Semaglutide, many individuals experience a reduced appetite and lower calorie intake. While this supports weight loss goals, it can also lead to nutritional deficiencies, particularly in key nutrients essential for healthy hair, such as:

• Protein – critical for keratin production and hair strength

• Iron and zinc – essential for follicle activity and cell renewal

• Vitamin D and B vitamins – support scalp health and new hair growth

Additionally, changes in insulin and hormone levels may alter the scalp’s oil production, follicle function, and growth cycles — all of which can contribute to increased shedding or slower regrowth.

Is the Hair Loss Permanent?

In most cases, no — it’s temporary. Telogen effluvium typically resolves within several months once the body stabilizes and underlying imbalances are addressed. However, without proper assessment, it can sometimes be confused with other forms of hair loss that require different treatment approaches.

That’s why a professional scalp and hair analysis is essential. It allows us to determine whether your hair loss is medication-related or influenced by other factors such as stress, genetics, or underlying scalp conditions.
