“I started my GLP-1, and three months later my hair started coming out in the shower. It has to be the medication.”
If that sounds like you, I understand. I remember the day I pulled a fistful of hair from my head on holiday. I remember the sick-in-the-stomach feeling of not knowing why it was happening, or whether it would ever stop.
My own hair loss began in 2008. As a registered nurse, I did what I was trained to do and went looking for the cause. I have spent well over a decade since then reading the research, writing a book about it, and answering questions from thousands of women. Today I have most of my hair back. Not because of a miracle oil, but because I worked out what was causing it.
Now the same question fills my inbox every week: is my GLP-1 doing this? The honest answer is rarely a simple yes or no. And the difference matters, because it decides what you should do next.
What the trials actually found
The numbers behind the headlines
3 in 100
people on semaglutide reported hair loss in the main weight-loss trial, against 1 in 100 on placebo
5–6 in 100
reported it on tirzepatide, where weight came off faster still, against about 1 in 100 on placebo
2–4 months
the usual gap between whatever set off the shed and the hair landing in your shower
50–100
hairs a day is a normal amount to lose, more on wash days

So most women on a GLP-1 never report hair loss at all. What is different about the ones who do?
GET THE GUIDE $19The idea that changes everything
A trigger is not the same as a cause
The trials compared people who lost a lot of weight quickly with people who barely lost any. Did the extra shedding come from the drug or from the fast weight loss and smaller meals the drug produced. Is it correlation or causation?
The trigger
The event that tips the balance. Find the event that tipped your balance to cause your hair loss in this highly researched guide.
The underlying causes
The quiet things that left your hair vulnerable in the first place. These are the things even your doctor isn't looking for.
The GLP-1 could be the trigger but it is rarely the whole cause.
Put a GLP-1 together with perimenopause, low iron and a diet that has shrunk to a few mouthfuls a day, and you have what I call a cocktail of causation. The medication is the newest ingredient, so it gets the blame.
If you only deal with the trigger, the underlying causes stay. The next dose increase, virus or hard year can set the shedding off again. Find them, and you give your hair its best chance to recover and stay.

GLP-1 Hair Loss: why is your hair shedding, and what can you do about it?
A practical, plain-English guide that walks you from “what is happening?” to “here is my plan”. Every clinical claim is referenced to peer-reviewed research or the official prescribing information, and where the evidence is thin, I say so.

Inside
What you will learn
Part one · Understanding your hair
- The two-to-four-month rule: why the hair falling today was told to stop growing months ago, and how to count back to what started it.
- Shedding, breakage or thinning? Three problems that look alike in the shower and need completely different fixes.
- What the GLP-1 trials really show, and why semaglutide and tirzepatide numbers differ.
- Correlation is not causation: Nicolas Cage films, swimming pools and the keto groups, and six questions to sort a cause from a coincidence.
Part two · The usual suspects
- Speed of weight loss, protein and side effects: how nausea and a tiny appetite quietly starve your follicles, and the daily protein range to aim for.
- Iron and ferritin: why you can be told your iron is “fine” when most guidelines would call it low, with Australian, UK and US cut-offs side by side.
- Thyroid, vitamin D, zinc and B12, plus the supplements you need to avoid that can make things worse.
- Hormones: female pattern hair loss, perimenopause, menopause and PCOS, and why they so often get blamed on the medication.
- Everything else: stress, illness, surgery, postpartum, other medicines, autoimmune and scalp conditions, and hair care damage.
Part three · Your action plan
- Be your own hair detective: I'll show you how to find your actual cause.
- Eating to protect your hair when you are full after a few bites, I'll show you what to eat so you can continue to lose weight and protect your hair.

Who wrote this
Hi, I’m Bambi
Former registered nurse · Author of Hair Loss in Women · Hair loss since 2008
I have been where you are. I know what it is like to check the drain after every wash, and to be told by well-meaning people that it is “probably just stress”.
My medical background taught me to look for the cause, not just the symptom. My own hair loss taught me that there is never just one. For more than a decade I have researched women’s hair loss, written about it, moderated an online support group, and listened to the stories of thousands of women.
I wrote this guide because women on GLP-1s deserve better than a one-line answer from a doctor who in all likelihood doesn't understand female hair loss. You can keep looking after your health and look after your hair too. You just need to know what you are dealing with.
Love,
