You're losing the weight. But you didn't expect to lose your hair too.
The weight came off — but so did your hair. It's happening to millions of women on Ozempic, Wegovy, and Mounjaro. It's not in your head, and there are real things you can do about it.

What's actually happening to your hair
When you lose weight rapidly, your body goes into metabolic shock. It prioritizes survival, and hair production isn't one of them, triggering Telogen Effluvium.
GLP-1 medications also reduce appetite, meaning you're eating less protein and missing key micronutrients — the literal building blocks of hair.
Reduced gut motility may also mean you're absorbing fewer nutrients from the food you do eat. The good news is this shedding is temporary and treatable.
7 things that actually help
Evidence-based, realistic, and doable even when you're busy.
Prioritize protein like your hair depends on it
Hair is 95% keratin. Aim for 80–100g of protein daily, even if not hungry. Liquid collagen peptides are ideal because they provide specific amino acids and bypass absorption issues caused by reduced gut motility.
Support externally while you rebuild internally
While addressing the nutritional root cause, use a topical scalp serum with Niacinamide and Rosemary extract to support scalp barrier function and calm the inflammation triggered by metabolic stress. Two-pronged defense is best.
Get your blood work done — don't guess
Ask your doctor to check: ferritin, vitamin D, zinc, B12, and thyroid function. GLP-1 weight loss can exacerbate existing deficiencies. Targeting the right levels is far more effective than general supplementation.
Don't crash your calories — slow weight loss preserves hair
Losing more than 2 lbs/week is a strong trigger for shedding. A steady 1–1.5 lbs/week is much gentler on your hair cycle. Slow but sustainable weight loss helps maintain your health and your hair.

Hydrate aggressively — it affects your scalp
Reduced food intake and GI side effects can cause dehydration. A dehydrated scalp becomes tight and inflamed, creating a hostile environment for growth. Aim for 80–100 oz of water daily with electrolytes.
Support gut absorption — it's likely compromised
Reduced gut motility affects how well you absorb nutrients. Switch to liquid or sublingual forms (like liquid collagen or vitamin D) that bypass the digestive bottleneck and ensure higher bioavailability.
Give it time — but know the timeline
Shedding follows a standard arc: peak shedding for 2–3 months, then gradual recovery. Total timeline is 6–12 months. Addressing nutritional gaps while staying on medication is what allows the cycle to normalize.
What to expect — Support Timeline
Every body is different, but this is the general arc for most women.
Nutrients reach the follicle. Shedding may continue as the old cycle completes. Scalp health begins to stabilize.
Shedding begins to slow as follicles adjust to support. Nails may strengthen — a sign the collagen is working.
New growth becomes visible. Hair feels more resilient. Shedding normalizes to healthy levels.
