There are several possible reasons why your henna brows might be patchy, including the following:
Incorrect application: If the henna was not applied evenly or was left on for an uneven amount of time, it could result in patchy coloring.
Poorly mixed henna: If the henna mixture was not properly mixed before use, it could result in patchy coloring.
Skin irritation: If you have sensitive skin or if the henna was left on for too long, it could cause irritation and result in patchy coloring.
Henna not suitable for eyebrows: Some types of henna are not formulated specifically for use on the eyebrows and may not provide the desired results.
To fix patchy henna brows, you can try using a mild exfoliant or oil-based cleanser to gently remove the top layer of dye. Alternatively, you can try using a brow lightening product specifically designed to fade henna. Keep in mind that these methods may not completely remove the henna, but they can help even out the color. It’s also a good idea to consult with a professional or do some more research before attempting any DIY fixes.
