Rapid weight loss from drugs like GLP-1 agonists can trigger temporary hair loss, medically known as telogen effluvium, due to the body prioritizing vital organs over hair growth. Experts advise early intervention, nutritional support, stress management, and medical treatments to mitigate and reverse hair fall.
Many individuals taking weight loss drugs such as Mounjaro and Wegovy have reported hair fall, causing concern. Dermatologist Dr. Kiran explains that this hair loss isn't directly caused by the drugs but by rapid weight reduction leading to telogen effluvium. This condition shifts hair follicles into the resting phase prematurely, resulting in excessive shedding.
Experts emphasize that the hair loss generally begins a few months after initiating treatment and is often temporary, improving as weight stabilizes. Nutrient deficiencies due to reduced appetite during medication use may exacerbate hair fall.
Doctors recommend multiple strategies to combat this issue:
-
Nutritional supplementation: Check and supplement iron, vitamin D, zinc, and folic acid levels to support hair health.
-
Gentle hair care & stress management: Avoid harsh treatments and manage psychological stress.
-
Advanced therapies: Treatments like red LED light therapy, platelet-rich plasma (PRP), and regenerative therapies may promote regrowth.
-
Medical consultation: Early diagnosis and treatment from dermatologists can prevent permanent damage.
Maintaining a balanced diet rich in proteins and micronutrients is crucial during rapid weight loss to support hair vitality.
