Hair Loss & GLP-1 Medication: What You Need to Know

Over the past year, we've had more and more guests sit down in our chairs and ask a similar question:

"Could my Ozempic be causing my hair loss?"

If you've noticed increased shedding, a thinner ponytail, less fullness around your face, or hair that simply feels different since starting a GLP-1 medication, you're not alone.

At Dwell, we know hair is deeply personal. Changes in your hair can impact your confidence, your routine, and how you feel when you look in the mirror. 

The good news is that understanding what's happening is the first step toward supporting healthier hair.

Let's talk about GLP-1 medications, hair loss, and what you can do if you're experiencing thinning or shedding.

What Are GLP-1 Medications?

GLP-1 medications have become increasingly popular for managing blood sugar levels and supporting weight loss.

Some of the most common include:

• Ozempic®

• Wegovy®

• Mounjaro®

• Zepbound®

These medications can be incredibly effective tools for many people. However, significant changes in the body often come with side effects, and one concern many users report is increased hair shedding.

Does Ozempic Cause Hair Loss?

The answer is a little more nuanced than a simple yes or no.

Current research suggests that GLP-1 medications themselves are not directly damaging hair follicles. 

Instead, hair loss is often associated with the rapid weight loss that can occur while taking these medications.

When the body experiences a major change, such as:

• Rapid weight loss

• Significant calorie reduction

• Nutritional deficiencies

• Physical stress

It may temporarily shift more hair follicles into the shedding phase of the growth cycle.

This condition is known as telogen effluvium.

What Is Telogen Effluvium?

Telogen effluvium is a temporary form of hair shedding that occurs when the body experiences a significant stressor.

This can happen after:

• Weight loss

• Surgery

• Illness

• Pregnancy

• Emotional stress

• Major lifestyle changes

The challenging part is that hair shedding usually doesn't start immediately. Many people begin noticing increased hair fall two to four months after the event that triggered it.

This often creates confusion because the shedding occurs long after the weight-loss journey has already begun.

Signs You May Be Experiencing GLP-1 Related Hair Shedding

Everyone's experience is different, but common signs include:

• More hair in the shower drain

• Increased hair in your brush

• A thinner ponytail

• Reduced density around the temples

• More visible scalp

• Hair that feels less full than usual

For many people, the issue isn't complete hair loss. Instead, it's a gradual reduction in density and fullness.

Supporting Healthy Hair During Weight Loss

While hair shedding can feel frustrating, there are ways to support your scalp and hair throughout the process.

Prioritize Protein

Hair is primarily made of protein.

When calorie intake decreases significantly, protein consumption often drops as well. Making sure you're getting adequate protein can help support healthy hair growth.

Always work with your physician, registered dietitian, or healthcare team to determine what's appropriate for your individual needs.

Pay Attention to Nutrients

Rapid weight loss can sometimes lead to nutrient deficiencies that impact hair health.

Some important nutrients include:

• Iron

• Vitamin D

• Zinc

• B Vitamins

If you're experiencing excessive shedding, consider discussing bloodwork with your healthcare provider.

Be Gentle With Your Hair

When hair feels fragile, gentle care matters.

We recommend:

• Limiting excessive heat styling

• Avoiding tight hairstyles

• Staying consistent with trims

• Using professional products designed to support scalp and hair health

How Dwell Supports Guests Experiencing Hair Thinning

One of the most important things we want guests to know is this:

You don't have to figure it out alone.

If you're experiencing thinning, shedding, or changes in your hair, we're here to help create a plan that fits your goals and lifestyle.

Personalized Consultations

Every guest's hair journey is different.

We start with a thoughtful consultation to understand what's changed, what you're experiencing, and what solutions may be the best fit for you.

Scalp & Hair Health Support

Healthy hair starts at the foundation. And every guest’s journey is different.

We may recommend treatments and routines designed to support:

• Scalp health

• Hydration

• Strength

• Breakage prevention

• Long-term hair integrity

Professional Backbar & In-Salon Options

1. Genesis Fusio-Dose Protocol

The most targeted professional treatment is a customized Fusio-Dose service using:

• Concentré Genesis (anti-breakage, strengthening)

• Paired with the appropriate booster for the guest's needs (nutrition, repair, shine, density, etc.).

This is an excellent add-on for guests reporting increased shedding, postpartum hair changes, stress-related hair fall, or weakened hair.

2. Genesis Anti-Hair-Fall Fortifying Treatment

Professional Genesis treatments focus on:

• Strengthening the hair fiber

• Reducing breakage-related hair fall

• Improving scalp and hair condition

• Supporting healthier-looking density over time
  

Supporting Stronger Hair with Kérastase Genesis at home

If your hair has been feeling weaker than usual, the right home care routine can make a meaningful difference.

One collection we're especially excited about at Dwell is Kérastase Genesis—a professional haircare system designed for weakened hair that's prone to breakage from brushing, styling, and everyday stress. 

While Genesis is not a treatment for medical hair loss or conditions like alopecia, it is an excellent option for guests whose hair feels fragile, dry, or more susceptible to snapping.

The philosophy behind Genesis is simple: strengthen the hair fiber so it can withstand daily wear and tear more effectively. 

By supporting hair from the scalp through the lengths, the collection helps reduce breakage and promotes healthier-looking, more resilient hair over time.

A Four-Step Ritual for Stronger-Looking Hair

The Genesis routine is built around four key steps:

• Cleanse with a fortifying shampoo that gently removes buildup while supporting weakened strands.

• Condition or treat with a nourishing conditioner or mask to reinforce the hair fiber and restore softness.

• Boost with the daily Genesis Serum Fortifiant, a lightweight leave-in scalp serum formulated to help support the scalp environment and strengthen hair at the root.

• Protect with Défense Thermique, a heat protectant that shields hair from styling temperatures up to 450°F while helping to reduce damage from blow-dryers and hot tools.

Together, these products create a comprehensive routine designed to support hair that's been stressed by heat styling, brushing, environmental factors, or chemical services.

Why We Love Genesis at Dwell

Many guests experiencing hair changes after significant weight loss notice not only increased shedding but also that their remaining hair feels finer, drier, or more prone to breakage. 

That's where Genesis shines.

Instead of simply masking the problem, the collection focuses on strengthening the hair fiber, improving manageability, and protecting against the everyday factors that can make thinning appear even more noticeable. 

Heat protection, hydration, and reinforcement all work together to help hair look fuller, healthier, and more resilient.

For guests who color or style their hair regularly, Genesis also fits beautifully into an overall healthy hair routine by helping to minimize mechanical damage and supporting long-term hair integrity.

Personalized for Different Hair Types

One of our favorite things about Genesis is that it isn't one-size-fits-all.

For fine-to-medium hair, lightweight formulas deliver strength without sacrificing movement. 

Guests with medium-to-thick or drier hair can benefit from richer masks and nourishing treatments that deeply reinforce the mid-lengths and ends. 

No matter your texture, the goal remains the same: healthier hair that's better equipped to handle daily styling and environmental stress.

Small Changes Can Make a Big Difference

Supporting your hair isn't just about one product—it's about consistency.

Using a strengthening shampoo, incorporating deep conditioning, protecting against heat, and caring for your scalp can all help reduce breakage and keep hair looking its best.

At Dwell, we're proud to offer the Kérastase Genesis collection as part of our commitment to healthy hair. 

If you've noticed increased fragility or want personalized recommendations for your hair goals, our team would be happy to help you build a routine tailored to you.

Retail Products to Support the Professional Service

Kérastase Genesis Bain Nutri-Fortifiant

Kérastase Genesis Fondant Renforçateur

Kérastase Genesis Défense Thermique

Kérastase Genesis Serum -  the hero product of the line. 

It is applied daily to the scalp and is designed to help anchor hair at the root while supporting a healthier scalp environment.

How Genesis Works

Genesis takes a "dual action" approach:

1. Strengthens the hair fiber

The shampoos, conditioners, masks, and Défense Thermique help reinforce weakened hair so it breaks less during:

• Brushing

• Heat styling

• Mechanical stress

• Daily wear and tear

When hair breaks less, fewer strands end up in the brush or shower, which many guests perceive as "less shedding." 

2. Supports the scalp environment

The serum contains:

• Aminexil – helps maintain flexibility around the follicle and improve anchoring of the hair fiber.

• Caffeine – supports scalp microcirculation.

• Ginger Root Extract – helps protect against external stressors.

• Edelweiss Native Cells – antioxidant protection. 

Kérastase describes this as helping "re-anchor" the fiber to the root and supporting a healthier scalp environment.

Up to 97% less hair fall due to breakage when the Genesis system is used as directed. 

84% less hair fall due to breakage after one application of the shampoo + masque + serum ritual.

"Genesis is clinically tested to significantly reduce hair fall due to breakage by strengthening weakened hair fibers. The best results are seen when the full Genesis regimen is used consistently."

Kérastase Chronologiste

Another collection we often recommend is Kérastase Chronologiste, a luxurious haircare ritual designed to revitalize hair and scalp while addressing common concerns such as dryness, dullness, frizz, and a sense of reduced fullness over time. 

If your hair has lost its softness or shine after weight loss, stress, or hormonal changes, Chronologiste helps restore hydration and smoothness while leaving hair feeling stronger, healthier, and more manageable.

At Dwell, we love Chronologiste for guests who want to elevate their overall hair health—not just by treating the strands themselves, but by creating an environment where healthy hair can thrive. 

Rich ingredients like hyaluronic acid help replenish moisture, making it an excellent complement to a well-rounded, healthy hair routine. 

If you're unsure whether Genesis or Chronologiste is the better fit for your goals, our team can guide you to the products and treatments best suited to your unique hair journey.

Hair Extensions for Density, Not Just Length

One of the biggest misconceptions about extensions is that they're only for creating dramatic length.

Many of our guests experiencing thinning are actually looking for something else:

More fullness.

Strategically placed extensions can help:

• Fill sparse ends

• Create a fuller perimeter

• Add density through the mids

• Improve overall shape and balance

At Dwell, we often use customized extensions to help guests feel more confident as their natural hair continues its journey.

One solution many guests prefer during periods of hair thinning is K-tip (keratin bond) extensions. 

Unlike traditional extension methods that rely on larger rows or concentrated points of tension, K-tips are applied strand by strand using small keratin bonds. 

This allows for highly customized placement, making them an excellent option for adding fullness exactly where it's needed most.

For guests experiencing reduced density due to hair shedding, K-tips can help restore volume around the perimeter, through the mids, and in areas that feel sparse, while maintaining natural movement and blend. 

When professionally installed and maintained, K-tip extensions are often considered one of the gentlest extension methods because the weight is distributed more evenly throughout the hair, reducing stress on any one section. 

For many guests, they provide a confidence boost and a fuller appearance while supporting the long-term health of their natural hair. 

The goal is hair that looks healthy, full, and effortless.

When Should You Talk to a Medical Professional?

While temporary shedding is common during significant weight loss, it's always important to speak with a healthcare provider if:

• Hair loss is severe

• Shedding continues for many months

• You notice bald patches

• You experience scalp irritation or discomfort

• You're concerned about nutrient deficiencies

A physician or dermatologist can help identify any underlying causes and recommend appropriate treatment options.
