From the Guidelines

Yes, there have been reports of scalp issues, including scabbing, associated with semaglutide use, though these are not among the commonly listed side effects. Semaglutide is primarily used for type 2 diabetes management and weight loss. Some users have reported various dermatological side effects, including scalp problems like dryness, itching, and scabbing, as noted in the context of its side effects profile 1. These symptoms may be related to the medication's effects on hydration status, as semaglutide can cause dehydration through its gastrointestinal side effects like nausea, vomiting, and diarrhea, which are well-documented in studies such as those referenced in 1. Dehydration can subsequently affect skin health throughout the body, including the scalp. If you experience scalp scabbing while taking semaglutide, it's essential to:

  • Increase your water intake
  • Consider using gentle, moisturizing hair care products
  • Consult your healthcare provider, who may recommend adjusting your dosage, providing symptomatic treatment, or in some cases, considering alternative medications if the side effects are severe or significantly impact your quality of life. The importance of monitoring and managing side effects is highlighted in guidelines for the use of semaglutide and other antiobesity medications 1.

Adverse Effects of Semaglutide

  • Semaglutide has been associated with various adverse effects, including dermal hypersensitivity reactions 2, gastrointestinal side effects 3, and allergic reactions 3.
  • There have been reports of skin hypersensitivity associated with GLP-1RA medications, including semaglutide 2, 4.
  • A case series reported allodynia (skin tenderness) associated with semaglutide, with symptoms developing after dose escalation 4.
  • However, there is no specific mention of scabbing on the scalp as an adverse effect of semaglutide in the available evidence.

Specific Adverse Effects

  • Dermal hypersensitivity reactions to semaglutide have been reported, with symptoms including eruption on the skin and histology showing subepidermal blister with eosinophils 2.
  • Gastrointestinal side effects, such as nausea and diarrhea, are common with semaglutide 3.
  • Allergic reactions, including anaphylaxis, have been reported with semaglutide 3.
