😳 GLP1 QUESTION: “Why is my hair falling out?!”
This one can be SCARY.
Hair shedding can happen during significant or rapid weight loss, including in people taking GLP1 medications.
But here's the important part:
It may not be as simple as “the medication is making my hair fall out.”
Rapid weight loss, inadequate calories, low protein intake, nutritional deficiencies, stress, thyroid issues, hormonal changes, and genetics can all contribute.
This is why I am constantly reminding everyone:
🥩 PRIORITIZE YOUR PROTEIN
🥗 Don't completely stop eating
💊 Make sure you're meeting your nutritional needs
⚖️ Faster weight loss isn't always better
But what if you're doing ALL of that and you're still losing hair?
That's when we can look deeper and discuss treatment options.
Depending on the patient and the cause of the hair loss, options may include:
💧 Topical minoxidil to help stimulate hair growth
💊 Low dose oral minoxidil for appropriate patients who may benefit from a systemic option
🧴 Finasteride or dutasteride in appropriately selected patients when androgen related hair loss is contributing
🧬 GHK Cu copper peptide is another option you may hear about. It has interesting early research involving hair follicles and tissue repair, but the evidence for actual hair regrowth in humans is much more limited than it is for medications such as minoxidil.
The most important part is figuring out WHY you're losing hair first.
If nutrition is good and the shedding continues, don't just assume you have to live with it. Talk with your provider about whether additional evaluation or treatment makes sense for you.
