It's always the hairdresser
who notices first.
Stylists are seeing the same thing over and over in clients who've lost a lot of weight quickly. The explanation has almost nothing to do with hair — and almost everything to do with arithmetic.
She has been cutting your hair for nine years. She knows the weight of it in her hand better than you do.
So she's the one who pauses. Sections it differently. Asks — carefully, because there's no good way to ask — whether you've changed anything lately.
And the honest answer is yes. You've changed the single biggest thing about your daily life. You're eating a fraction of what you used to.
Across the country, stylists are having some version of this conversation constantly right now. Clients thrilled with the scale, six months into one of the new weight loss medications, quietly asking whether there's a cut that would make thinner hair look intentional.
Almost none of them were told this might happen. And almost all of them assume it means something is wrong with them.
It isn't the medication failing you. And it isn't you failing. It's arithmetic.
Food was never just calories
These medications work by turning down appetite. That's the entire point, and it works — people on them commonly end up eating thirty to forty percent less food than before.
Here's the part that doesn't get explained at the appointment.
Food is not just where calories come from. Food is where your iron comes from. Your zinc. Your B12, your folate, your magnesium, your vitamin D.
Cut your food intake by forty percent and you have not simply created a calorie deficit. You've created a deficit of everything else that was riding along with those calories.
Your body notices. And research is now catching up to what patients have been reporting to each other in online forums for two years.
- A 2025 clinical study measured a median 13% drop in intestinal iron absorption within ten weeks on semaglutide-class medication — with nearly one in five patients dropping 30% or more. Melis et al., Diabetes, Obesity and Metabolism, 2025
- A 2026 review spanning roughly 480,000 adults found that by month six, 12.7% had a newly diagnosed nutritional deficiency — vitamin D most common, then iron and B vitamins. Urbina et al., Clinical Obesity, 2026;16(1):e70070
- Dermatology literature has long identified rapid weight loss and restricted intake as classic triggers for telogen effluvium, a temporary shedding pattern associated with low iron, zinc, vitamin D and protein. It characteristically appears about three months after the change begins. American Academy of Dermatology; Cleveland Clinic
Three months. Which is roughly when the compliments start — and, for a lot of people, roughly when the shower drain starts looking different.
"But I already take a multivitamin"
Fair. And here's why that may not be covering this.
A standard multivitamin is dosed for a person with a normal appetite, absorbing nutrients across three full meals a day. That describes almost nobody in month six of appetite-suppressing medication.
You're eating less. Depending on the nutrient, you may be absorbing less of what you do eat. And many drugstore multis use nutrient forms your body has to convert before it can use them — one more step in a system already running lean.
It isn't that cheap multivitamins are a scam. It's that they're answering a different question. Yours is a specific situation: a planned, medically supervised deficit. Different situation, different arithmetic, different formula.
What replenishment actually looks like
This is the gap Restore Well was built for — and it's worth being precise about what that means, because this category is full of people who aren't.
Restore Well Daily Replenishment Complex
- The nutrients the deficiency research points at. Iron as ferrous bisglycinate chelate (18 mg), zinc bisglycinate (20 mg), vitamin D3 (50 mcg), and magnesium (200 mg) — to support normal energy metabolism, immune function, and muscle function.*
- Pre-activated B vitamins. Methylcobalamin B12 and active folate as L-5-MTHF — forms the body uses directly, without conversion steps.*
- Absorption support. BioPerine® black pepper extract, studied for enhancing absorption of co-administered nutrients. Nutrients in a capsule are worth nothing if they don't get into you.*
- Made for a stomach that's currently opinionated. Ginger root, peppermint, bromelain and digestive enzymes, plus LactoSpore® (Bacillus coagulans) at 6 billion CFU, to support digestive comfort.*
The full supplement facts panel is printed on the bottle and published on the product page. Nothing is hidden inside a proprietary blend, and there are no ingredients in there at doses too small to matter — the ones worth naming are the ones we named.
The honest part about timing
A deficit that accumulated over months does not correct in a week. Nutritional replenishment is slow, unglamorous, and compounding, and anyone selling you a faster story is selling you a story.
That's why most people here start with the full ninety days rather than a single bottle. Not because bigger orders are nicer for us — because a thirty-day trial of a ninety-day process is a test designed to fail.
Take it every day. If at the end you don't think it was worth it, email us and we refund the order in full. You don't ship anything back. That's the entire policy.
You already did the hard part. You made the decision, you started, and it's working.
This is just making sure the rest of you comes along with it.
