From the Guidelines

There is currently limited evidence directly linking trizepatide to hair loss as a common side effect, and any reported hair loss may be related to rapid weight loss rather than a direct effect of the medication itself. In clinical trials of trizepatide, such as the SURMOUNT-1 trial 1, hair loss was not reported as a significant adverse event. However, some patients using trizepatide have anecdotally reported experiencing hair loss. When people lose weight quickly, they may experience a condition called telogen effluvium, where hair follicles prematurely enter the resting phase and subsequently shed. This is typically temporary, and hair growth usually resumes once weight stabilizes.

Some key points to consider:

  • Ensure adequate protein intake (at least 0.8-1g per kg of body weight daily) to support hair growth.
  • Maintain proper nutrition with sufficient vitamins and minerals (particularly iron, zinc, and vitamins D and B).
  • Consider discussing the issue with your healthcare provider, who may recommend blood tests to check for nutritional deficiencies or other underlying causes.
  • Most cases of weight-loss related hair shedding resolve within 3-6 months as the body adjusts to the new metabolic state.

It's essential to prioritize overall health and nutrition while taking trizepatide, as the medication is intended to support weight loss and improve related health outcomes, as seen in studies such as the SURMOUNT-1 trial 1. If you're experiencing hair loss while taking trizepatide, it's crucial to discuss this with your healthcare provider to rule out any underlying causes and ensure you're receiving adequate nutrition.

From the Research

Trizepatide and Alopecia

There are no direct research papers to assist in answering this question. However, some studies provide information on hair loss and its potential causes:

  • Hair loss can be caused by various factors, including caloric deprivation, deficiency of proteins, minerals, essential fatty acids, and vitamins 2.
  • Deficiencies or imbalances in micronutrients such as vitamin B, vitamin D, iron, and zinc may contribute to the pathogenesis of androgenetic alopecia, a common type of nonscarring hair loss 3.
  • Female pattern hair loss is a common form of hair loss in women, and its etiology is unknown, with numerous factors influencing its onset 4.

Trizepatide Mechanism and Side Effects

Some studies provide information on trizepatide's mechanism and side effects:

  • Trizepatide is a GIP/GLP-1 receptor agonist used for the treatment of type 2 diabetes and obesity, and its absorption, distribution, metabolism, and excretion have been studied in humans and preclinical species 5.
  • Treatment with trizepatide has been associated with lower hazards of all-cause mortality, adverse cardiovascular events, acute kidney injury, and adverse kidney events compared with GLP-1 RA in patients with type 2 diabetes 6.
  • However, none of these studies mention alopecia or hair loss as a potential side effect of trizepatide.

Key Findings

Key findings related to hair loss and trizepatide include:

  • No direct evidence linking trizepatide to alopecia or hair loss
  • Hair loss can be caused by various factors, including nutritional deficiencies and micronutrient imbalances 2, 3
  • Trizepatide's mechanism and side effects have been studied, but alopecia or hair loss is not mentioned as a potential side effect 5, 6
