Hair Loss on Ozempic or Mounjaro? Here’s Why It Happens – and How to Protect Your Hair
As more people in the UK turn to GLP-1 medications like Ozempic®, Mounjaro®, or Wegovy® for weight loss or diabetes management, a lesser-discussed side effect is quietly gaining attention: hair loss.
Although not experienced by everyone, many users report hair thinning, increased shedding, or slower regrowth — usually within the first 2–4 months of treatment.
Let’s unpack the likely causes, what science says about nutrient-related hair health, and how TRINITY can help support stronger, healthier hair from within.
💇 Why Does Hair Loss Happen on Ozempic or Mounjaro?
Hair loss from GLP-1 medications isn’t due to the drug directly damaging hair follicles. Instead, it’s the indirect effects on nutrient intake, stress and hormonal balance that set the stage for shedding.
1. Caloric restriction & rapid weight loss
Significant drops in calorie intake signal to the body that it’s under stress. Hair is non-essential to survival, so follicles shift from the growth phase (anagen) to the shedding phase (telogen) in response.
2. Nutrient deficiency
Reduced appetite means you may be missing vital hair nutrients like biotin, zinc, iron, selenium and protein — all critical to hair growth and follicle strength.
3. Hormonal stress
Changes in insulin, cortisol, and thyroid function during GLP-1 treatment can temporarily affect the hair growth cycle.
🧪 Key Nutrients That Support Hair Growth (and May Be Lacking)
| Nutrient | Role in Hair Health | Risk While on GLP-1s |
|---|---|---|
| Biotin (Vitamin B7) | Strengthens hair structure and keratin production | Low food intake reduces natural intake |
| Zinc | Regulates hair follicle activity, reduces shedding | Often under-consumed during calorie restriction |
| Iron | Supports oxygen delivery to follicles | Missing meals = iron shortfall |
| Selenium | Antioxidant protection for follicles | Limited intake + stress = depletion |
| Vitamin C | Aids iron absorption and collagen production | Less fruit/veg = lower C levels |
| Vitamin B-complex | Needed for healthy cell turnover and follicle repair | Easily depleted on restricted diets |
