The good news? It's often temporary and reversible.
Noticing more hair shedding since starting a GLP-1 medication? You're not alone!
Hair loss has been reported with medications like Zepbound and Wegovy, but the medication itself may not be the only factor.
One common explanation is telogen effluvium, a condition where physiological stress, including rapid weight loss, causes increased hair shedding. This isn't unique to GLP-1s. We've seen similar patterns for years following bariatric surgery.
The good news?
Telogen effluvium is typically reversible! Once the underlying trigger is addressed, shedding usually improves, although regrowth can take several months.
So what can you do?
🔎 Get the right diagnosis. Not all hair loss is the same. A dermatologist can identify the type of hair loss and determine whether testing for iron deficiency, thyroid dysfunction, or other nutritional deficiencies is appropriate.
💊 Explore treatment options. Topical minoxidil (particularly 5% foam) is a well-established treatment for certain types of hair loss and is often better tolerated than liquid formulations. Oral minoxidil and spironolactone may help select patients, but aren't appropriate for everyone. Pattern hair loss often requires ongoing treatment, while telogen effluvium frequently resolves without medication.
🥗 Prioritize protein! Hair is primarily made of keratin, a structural protein. Inadequate protein and calorie intake can contribute to shedding, especially when appetite is significantly suppressed.
⚖️ Find your optimal GLP-1 dose. If appetite suppression is preventing you from meeting your nutritional needs, discuss your dosing strategy with your provider. Higher doses aren't always better!
At Revolution Medicine, we believe successful weight management means preserving muscle, supporting nutrition, and prioritizing overall health, not just lowering the number on the scale.
Bottom line: Hair shedding during weight loss is often temporary and manageable. Identifying the underlying cause is the first step toward healthier hair!
