Losing more hair since you started Ozempic or Wegovy?

You're not imagining it. And nobody warned you about this part.

The weight is finally coming off. You did the hard thing. And then, somewhere around the third month, your hair started coming off with it.

More in the shower drain than there used to be. A ponytail that wraps around an extra time. A part you keep checking in the mirror, in bad light, hoping you're imagining it.

None of this is your fault

This is not the medication attacking your hair. It isn't a sign you did something wrong. It's the speed.

When you eat a fraction of what you used to and lose weight fast, your body has to make choices. It feeds your heart, your brain and your organs first. Hair is a luxury it can cut. So it does. Here's the sequence:

• 01You eat less. Appetite all but disappears, and protein and the vitamins and minerals your hair is built from drop with it.
• 02The follicle goes quiet. Underfed, hair slips early out of its growing phase and into a resting phase.
• 03Two to three months later, it lets go. Which is why the timing feels so cruel. You finally feel good about your body, and the drain fills up.

Specialists call it telogen effluvium. It's the same shedding women see after surgery, childbirth or a crash diet. It shows up in the drug maker's own trial data, too: in Wegovy's trials, the women who lost the most weight reported the most shedding.

The follicle is starved, not damaged. That distinction matters, because a starved follicle can be fed.

Will it grow back?

Usually, yes, once your weight steadies and your eating evens out. But while the weight is still dropping, this does not settle on its own. Every week the follicle stays underfed, more hair slips into the shedding phase, and hair that returns after a long, unchecked shed comes back finer than what it replaced.

The hair you have now is the most you'll ever have to work with. The time to feed it is while you're losing, not after.

Three tests for any hair vitamin

Two things cost nothing: more protein than feels comfortable, because hair is mostly protein and it's the first thing you run short on, and, if you can, a slower pace (ask your prescriber). The third costs money, and it's where women waste it. I've tested dozens with my clients, this past year especially with women on a GLP-1, because it's a different problem from ordinary thinning.

• Test oneIs it a complete blend, or just biotin?Eating a third of what you used to, you're short on several nutrients, not one. You want biotin alongside vitamins A, C and E, the B group and zinc. A bottle that's mostly biotin fixes one gap and ignores the rest.
• Test twoCan you actually take it on no appetite?Four fish-based capsules on an empty stomach is a lot to ask when food itself is a chore. If you can't keep it down, or keep it up, the formula doesn't matter.
• Test threeCan you afford to finish?Hair runs on a ninety-day clock. A formula you quit in month two over price was money spent on nothing. So was a cheap bottle without the full blend.

Grade any bottle against those three and you barely need me. Here's how the five best-known options graded.

Value: a complete formula at a price you can stay on for the full ninety days, not simply the cheapest bottle.

Weight-loss shedding (telogen effluvium) usually eases as your weight steadies and your eating evens out; shedding that continues past about six months is worth checking with your doctor.
