* Uneven color: Grease can act as a barrier, preventing the hair dye from penetrating the hair shaft evenly. This can result in patchy or uneven color.
* Faded color: The grease can dilute the hair dye, leading to a less vibrant or less permanent color result.
* Irritated scalp: Some hair dyes can be irritating, and grease can trap the dye against your scalp, potentially causing more irritation.
What to do:
1. Wash your hair: It's best to wash your hair with a clarifying shampoo before dyeing. This will remove any excess oils and ensure the dye can penetrate the hair effectively.
2. Use a clarifying shampoo: A clarifying shampoo is designed to remove buildup from hair, including grease.
3. Condition lightly: After washing, apply a light conditioner to the ends of your hair to keep it hydrated. Avoid applying conditioner to your scalp.
Important Note: Always follow the instructions on your chosen hair dye product carefully. If you have any concerns, consult with a professional hairstylist.
