Hair Loss from Weight Loss Injections: Causes, Prevention & Treatment

If you're considering weight loss injections or are already using them, you may have heard about hair loss as a possible side effect. It’s been a hot topic lately, with medications like Ozempic and Wegovy also known as 'Skinny Jab' making the headlines, including on ITV’s This Morning.

Not everyone will experience this, but if you do, it can be unsettling. The good news? It’s usually temporary, and there are steps you can take to protect your hair before, during, and after treatment.

Why Does Hair Loss Happen?

It’s not just the medication itself, but how it affects your body:

Caloric Restriction & Stress on the Body – When your calorie intake drops significantly or becomes irregular, your body prioritises essential functions over hair growth. This can push follicles into a resting phase (telogen effluvium), causing shedding a few months later.
Nutritional Deficiencies – A reduced appetite can mean less intake of key vitamins and minerals like protein, biotin, zinc, and iron - all crucial for hair health.
Hormonal Changes – Weight loss injections mimic hormones that regulate blood sugar, and these shifts can disrupt the natural hair growth cycle.

Can You Protect Your Hair Before & During Treatment?

Yes, you can take steps to minimise hair loss and keep your hair as healthy as possible:

Pre-Injection Testing-A simple blood test or a Fagron DNA Tricho Test can check for deficiencies in key nutrients. Knowing what your body needs means you can supplement or adjust your diet before starting treatment.
Targeted Hair Care & Nutrition–Using the right hair and scalp products, alongside a nutrient-rich diet, can help keep your hair strong and resilient during your weight loss journey.
