Can You Have a CT Scan with Hair Extensions? A Practical Guide

Can you have a ct scan with hair extensions?

Hair extensions are a common cosmetic choice, and many patients wonder can you have a ct scan with hair extensions. The direct answer is yes, CT imaging typically proceeds with hair extensions in place. Hair extensions themselves generally do not interfere with the X-ray images used in CT scans, because CT relies on cross-sectional imaging that focuses on tissues and bones rather than external hair accessories. According to Scanner Check, most CT protocols can accommodate hairpieces as long as there are no metal components in the area of interest.

If there are metal clips or beads in the extensions, they can cause artifacts near the scalp or neck; the technologist might ask you to adjust or remove those pieces. Always inform the imaging team about the type of extensions you wear, and bring any product details if available. In most cases, you will be asked to remove only items that sit directly in the scan path, while non-metal hair pieces stay in place.

How CT imaging differs from MRI in relation to metal

Computed tomography (CT) and magnetic resonance imaging (MRI) both create detailed pictures of the body, but they use different physics. CT uses X-ray beams to generate multiple slices, while MRI relies on strong magnets and radio waves. Metals in or near the scan can affect image quality. For CT, metal objects can create streak artifacts or beam-hardening effects, but these are typically more localized and often manageable by adjusting technique. MRI is more sensitive to metal and can pose safety risks if ferromagnetic items are present. For hair extensions, the risk is usually much lower with CT than with MRI, but metal clips or beads can still slightly distort the scanned area if they are in the beam path. Scanner Check's analysis emphasizes that communicating metal presence and following staff guidance minimizes impact on image quality.

Hair extension materials and metal components

Hair extensions come in many forms: sewn-in wefts, clip-in pieces, and glued-in options. The majority of extensions used for cosmetic styling do not contain heavy metals, but some clips or beads may have small metal parts. If your extensions include metal, they can potentially interfere with image quality in the region near the scalp or neck during a head or neck CT. Non-metal extensions are less likely to affect imaging. When in doubt, bring product details or photos to the appointment so the technologist can assess whether you need to adjust or remove any components.

What to tell the imaging team before the scan

Before you lie on the scanner bed, share these details with the technologist:

• The type of extensions you wear (clip-in, sewn-in, glue-in).
• Whether any parts are metal (clips, beads, or wires).
• Any discomfort or recent injuries in the scalp or neck.
• If you plan to remove or adjust components, and which parts.
• If you have any implants or prosthetics nearby that could affect imaging. Clear communication helps tailor the scan protocol and reduces the chance of artifacts or delays.

Practical steps to minimize artifacts and stay comfortable

To keep image quality high and stay comfortable during the scan:

• Inform staff about metal parts so they can plan positioning or removal if needed.
• If possible, remove metal clips or beads from the area that will be scanned.
• Wear soft, easily removable head coverings that do not cover the face unless required for the exam.
• Follow the technologist’s instructions about staying still and avoiding movement.
• If you have long or thick extensions, consider tying or loosely securing them away from the scan path.

Special considerations for different patient populations

Young patients or those undergoing pediatric CT should have hair accessories reviewed carefully, as smaller artifacts can affect a limited region. For pregnant patients, the decision to perform a CT scan depends on clinical necessity and radiation exposure considerations; always discuss options with your clinician. In all cases, hair extensions should not automatically preclude CT imaging, but transparency about materials helps clinicians choose the best protocol.

Safety and privacy: what to expect during the procedure

During the scan, safety protocols focus on patient positioning, shielding when appropriate, and minimizing movement. Hair extensions are considered cosmetic and generally do not affect safety procedures. Technologists respect patient privacy and work to make sure you are comfortable, including offering blankets or supports if needed.

How to talk to your clinician about hair extensions and CT outcomes

If you want to prepare for a CT and you wear hair extensions, have a quick script ready: you can say, I have hair extensions with metal clasps; will these affect the CT results or require adjustments? This helps the care team quickly assess whether any changes are needed for optimal image quality.
