Bigen hair color products are designed to work with a variety of hair types, including straight, wavy, and curly hair. However, everyone's hair is unique, and results may vary based on individual hair condition and previous treatments.

• Always perform a patch test before full application to check for any sensitivity.
• It's a good idea to read the instructions carefully and follow all safety guidelines included in the packaging.
• If your hair has been chemically treated or is very fragile, consider consulting a professional stylist before coloring.

Using the right product for your hair type can help you achieve a more even and natural-looking result.

The longevity of Bigen hair color depends on the specific product and your hair care routine. Generally, permanent powder hair color can last several weeks, while semi-permanent options may fade more quickly, especially with frequent washing.

• Permanent color typically lasts until new hair grows out or the color is cut off.
• Semi-permanent color gradually fades over 4–6 weeks.
• To help maintain your color, use color-safe shampoos and avoid excessive heat styling.

Individual results can vary, so it's helpful to follow the aftercare instructions provided with your product.

Like with any hair dye, some people may experience side effects when using Bigen products. Possible reactions include scalp irritation, itching, redness, or allergic responses.

• Always do a patch test 48 hours before coloring to check for sensitivity.
• If you notice any discomfort or unusual symptoms, rinse immediately and consult a healthcare professional.
• Be sure to follow all instructions and safety warnings provided in the product packaging.

Taking these precautions can help minimize the risk of side effects during your coloring experience.

Bigen hair color products are formulated to help blend and cover gray hair. Many options, including permanent and semi-permanent formulas, are designed to provide even color coverage.

• For best results, select a shade close to your natural color.
• Apply according to the instructions for even application.
• Results may vary depending on the amount and texture of gray hair.

If you have a high percentage of gray or resistant hair, you may want to repeat the process or consult a stylist for tips on achieving optimal coverage.

If you get hair dye on your skin during application, there are a few gentle ways to help remove it:

• Wipe the area with a damp cloth as soon as possible.
• Use a small amount of gentle soap or makeup remover on a cotton pad.
• Avoid scrubbing harshly to prevent skin irritation.

For future applications, applying a thin layer of petroleum jelly around your hairline can help prevent staining. Always follow the product's instructions for safe use and cleanup.
