Can GLP-1 Medications Affect Lash Extensions or Lash Lifts?

What Every Client Should Know Before Their Appointment

By Mitzi-Jo Runyan Founder of Lashlette | Brentwood, Los Angeles

One of the things I love most about working in beauty is that lashes rarely exist in isolation.

People often think I'm looking at eyelashes.

I'm not.

I'm looking at a person.

A few months ago, a client sat down in our lash artist's bed and said, "My lash extensions aren't lasting anymore."

Like many clients do, she assumed the problem had to be the adhesive.

Then she casually mentioned she'd started a GLP-1 medication a few months earlier and had already lost nearly thirty pounds.

That changed the conversation.

Not because I believed the medication had damaged her lashes.

Because her body was doing something extraordinary.

When our bodies change quickly—whether from pregnancy, menopause, surgery, illness, significant weight loss, emotional stress, or a new medication—our hair often changes too.

Most people notice it on their scalp.

Few realize the same biology applies to eyelashes.

Your lashes don't know you're preparing for a vacation.

They don't know you have family photos next week.

They respond to biology, not your calendar.

That's one of the reasons I've never believed beautiful lash extensions begin with glue.

They begin with understanding who is wearing them

Over the past year, I've had more conversations about GLP-1 medications than I ever expected.

Ozempic.

Wegovy.

Mounjaro.

Zepbound.

Rybelsus.

The names are different, but the questions are remarkably similar.

"Why don't my lashes seem as full?"

"Why isn't my lash lift lasting as long?"

"Did the medication ruin my lashes?"

The honest answer is that we don't have evidence showing these medications directly cause eyelash loss as a common side effect.

What we do know is that the body often responds to significant change in predictable ways.

Rapid weight loss, changes in nutrition, lower calorie intake, shifting hormone levels, recovery from illness, and even emotional stress can all influence the hair growth cycle.

Eyelashes are hair.

They're simply much smaller.

Every eyelash grows, rests, sheds, and starts over again. That cycle continues throughout your life, quietly responding to what's happening inside your body.

Sometimes the changes are so subtle you never notice.

Sometimes they're enough that your lash extensions seem to shed sooner or your lash lift doesn't look quite like it did six months ago.

That doesn't automatically mean anything went wrong with the treatment.

Sometimes it means your body is adapting to a completely different version of itself.

That's why consultations have become even more important than when I opened Lashlette.

People often think I'm asking about medications, vacations, exercise, or nutrition because I'm making conversation.The truth is, I'm collecting pieces of a puzzle.

A woman training for her first marathon asks something different of her body than a woman recovering from surgery.

A woman beginning menopause has different needs than a college student eating in a dining hall.

A woman taking a GLP-1 medication may have different nutritional needs than she did a year ago.

Those details influence beauty in ways that are easy to overlook.

The lashes are often the messenger.

Not the problem.

One of the biggest lessons beauty has taught me is that our bodies are always communicating with us.

Sometimes through our skin.

Sometimes through our hair.

Sometimes through our eyelashes.

Learning to listen is far more valuable than finding someone to blame.

That's why I never want a client to feel discouraged if their lashes suddenly behave differently.

I want them to understand that beauty isn't separate from health.

It's often a reflection of it.

If you've recently started a GLP-1 medication and you've noticed changes in your lash extensions or lash lift, tell your lash artist. Because understanding what's happening in your life allows us to adjust the plan instead of guessing.

Beautiful lashes have never been about finding the strongest adhesive.

They've always been about understanding the person wearing them. xo
