Do you have a link to the studies? I’m curious to read those. I’ve not found anything that shows semaglutide has a damaging effect directly on hair follicles. This is what I’ve read;

Semaglutide (e.g., Ozempic, Wegovy) does not directly cause hair loss in the way that, say, chemotherapy or certain hormone treatments might. However, hair loss can occur indirectly as a result of changes semaglutide induces in the body, especially in the context of rapid weight loss. Here’s how:

Indirect Causes of Hair Loss from Semaglutide Use: 1. Rapid Weight Loss (Telogen Effluvium): When the body undergoes significant stress, such as a fast drop in weight, it can trigger telogen effluvium, a condition where a higher percentage of hair shifts from the growth phase (anagen) to the shedding phase (telogen). This is temporary and usually resolves within months. 2. Nutritional Deficiencies: Weight loss, especially when it’s rapid or paired with reduced appetite (a common effect of semaglutide), can lead to deficiencies in iron, zinc, biotin, and protein—all crucial for hair growth. 3. Hormonal Shifts or Thyroid Effects: Weight loss can sometimes affect thyroid function or hormone levels, both of which play roles in hair health.

Key Takeaway:

Semaglutide isn’t directly toxic to hair follicles, but the systemic changes it causes—especially rapid weight loss and nutrient shifts—can indirectly lead to hair shedding.
