If you’ve started a new weight-loss medication and noticed more hair in your brush lately, you’re not alone - and you’re not imagining it. Many women report increased hair shedding while on modern weight-loss drugs like Ozempic® and Mounjaro®.
The good news? In most cases, this hair loss is temporary, reversible, and treatable.
Let’s break down what’s really happening - and what you can do to get your hair (and confidence) back.
Why Hair Loss Happens During Weight Loss
When your body is adjusting to rapid weight changes, it can go into short-term “survival mode,” prioritizing essential functions and redirecting nutrients away from less essential functions. Here's some more about what happens and why:
Telogen Effluvium:
Losing weight quickly - whether through medication or diet - can trigger a type of shedding called telogen effluvium, characterised by thinning or shedding of hair. Your body temporarily shifts resources away from non-essential functions like hair growth to focus on vital systems - so your hair isn't receiving what it needs.
Nutrient Changes:
Reduced appetite means you may be eating less protein, iron, zinc, or vitamins – these are all nutrients your hair follicles depend on.
Medication Effects:
Some medications can affect how your body absorbs nutrients, or they may increase stress hormones that influence the hair cycle.
But don’t worry - in most cases, this shedding is temporary and once your body adapts or your nutrition improves, the hair growth cycle generally normalizes.
The Reassuring Truth: Hair Grows Back
Hair loss is really upsetting but most women start to see regrowth within three to six months after stabilising their weight, improving nutrition, or adjusting medication. In the meantime you can absolutely support your hair’s recovery - both from the inside and the outside.
1. Nourish from within
- Prioritize protein (fish, eggs, beans, tofu).
- Add iron, zinc, vitamin D, and B12 through diet or supplements (consult your GP).
- Consider a daily multivitamin with biotin for extra support.
2. Treat your scalp with care
- Gentle scalp massage boosts circulation.
- Avoid tight hairstyles, heat damage and harsh chemicals.
- Use tried and tested scalp treatments - look for slow release products and ingredients like peptides, caffeine, biotin, hyaluronic.
4. Consider targeted treatments
- Hairfix offers a range of specially targeted (as opposed to general) treatments depending on the area and severity of your loss/thinning. Take our quiz to find what’s best for you or contact us with your questions.
5. Keep calm - literally
- Stress itself can trigger hair shedding but hair will regrow, so try not to worry or over-style your hair
- Focus on self-care: sleep well, move your body, and nourish your mind.
