I Lost 55 pounds on GLP-1 But All of My Hair Fell Out — Now It's Regrown, Fuller and Stronger Than Ever, While I'm Still on GLP-1

Hey, I'm Rachel — and yeah, I'm the one who lost 55 pounds on a GLP-1 and nearly lost all my hair in the process.

Honestly, I'm not sharing this because I have it all figured out. I'm sharing it because eight months ago I was standing in my bathroom at 6am, looking at the hair wrapped around my fingers after one shower, and I had nobody to call who actually understood what was happening to me.

I'd started a GLP-1 medication fourteen months ago. Best decision I ever made for my body. The weight came off steadily. My energy shifted. My clothes started fitting differently. For the first time in years I felt genuinely proud of myself.

And then around month three, the hair started going.

It wasn't dramatic at first. A little extra in the brush. A ponytail that felt thinner than I remembered. I told myself it was stress, or the change in seasons, or just something that would pass.

By month five my hairdresser went quiet mid-cut. That kind of quiet where you know something is being decided before it gets said.

"Have you been losing more hair than usual?"

I had. I just hadn't wanted to say it out loud yet.

Honestly, I Was Ready To Give Up...

I'd tried the biotin. I'd tried the protein shakes. I'd bought a "hair, skin and nails" vitamin from the pharmacy that made exactly zero difference. My doctor had told me twice that it was temporary. My dermatologist had shrugged.

I was starting to believe them. That this was just the deal. That the version of me who lost the weight would always be the version of me with thinner hair.

And then, completely by accident, I fell down a research rabbit hole at midnight that I never expected to find anything useful in.

A thread buried in a forum. A woman, a nurse, actually, describing the exact same shedding pattern, the same timeline, the same failed attempts. And then one line that stopped me completely:

"This isn't a hair problem. It's a collagen and NAD+ deficiency. Your follicles are starving."

Okay wait — why is nobody saying this? Why had not one doctor, not one dermatologist, not one pharmacist mentioned this to me?

And just like that... it all made sense

My hair wasn't falling out because of the medication. It was falling out because of what the medication was doing to my nutrition.

When you eat significantly less on a GLP-1, your body stops sending resources to anything it considers non-essential. Hair is first on that list. Collagen disappears from your diet, so your follicles lose the protein they need to stay anchored. NAD+ crashes, so the stem cells responsible for new growth can't function. Vitamin C quietly drops too — and without it, your body can't convert collagen into new hair even if it's there.

Three nutritional deficiencies. All hitting at once. All caused by eating less.

That's why the biotin didn't work. That's why the protein shakes didn't work. None of them addressed the actual problem — and none of them addressed all three together.

That's when I started looking for something that did.

I Finally Understood Why Nothing Had Worked...

Every Single Thing I'd Tried Was Missing These

Collagen Peptides

Your follicles are built from collagen amino acids. When GLP-1s reduce your food intake, collagen is the first thing to disappear — and the first thing your hair needs back.

Nicotinamide Riboside (NR)

The most bioavailable way to restore NAD+ — the cellular energy your dormant follicles need to start functioning again. Clinically tested in women 36–60 specifically for hair and skin.

Vitamin C

The cofactor that makes collagen actually work. Without it, your body cannot convert collagen peptides into new hair tissue. Most supplements leave it out entirely.

Hyaluronic Acid

Supports the scalp environment that keeps follicles alive and anchored. Proven in 2025 trials to increase epidermal thickness — not just surface hydration.

So I Built My Own Stack

I spent three weeks trying to piece it together myself. A collagen powder, an NR capsule, a vitamin C supplement, an oral hyaluronic acid. Four separate products, four separate routines, trying to make sure I was actually hitting the doses the research pointed to.

It worked out to just over $200 a month.

And I still wasn't confident I was doing it right.

Then someone in one of the forums mentioned GLOW+. A single gummy that had all four — collagen, NR, vitamin C, hyaluronic acid. -Already dosed correctly, for less than $40 a month.

I ordered it the same night.
