Planning darker brows during GLP-1 treatment? Check these points before booking.
1. Is this a home tint kit?
FDA advises against tinting eyebrows or eyelashes at home. This applies even when a kit is sold online. [2]
2. What is the professional product?
FDA permits silver nitrate for professional-only brow and lash coloring: up to 4% in a viscous gel, not for under-16s or application beyond one minute. These products cannot be sold directly to consumers. [1]
3. Is scalp dye being substituted?
Coal-tar scalp hair dyes are not permitted for eyebrow or eyelash dyeing. FDA reports eye injuries, including blindness, from hair dyes used near eyes. [3]
4. Is the eye area inflamed?
FDA advises avoiding eye cosmetics during an eye infection or surrounding skin inflammation. Wait until healed. Permanent brow and lash dyes have caused serious eye injuries. [1]
5. What if a reaction starts?
Stop the product and contact your healthcare provider about a rash, burn or other unexpected reaction. FDA also accepts cosmetic problem reports. [2]
