No, you generally don't mix onion juice directly into shampoo. Instead, onion juice is typically applied to the scalp before shampooing.
The standard procedure, based on available information regarding onion juice use for dandruff, is to apply a mixture containing onion juice to the hair and scalp, let it sit for 20-30 minutes, and then wash the hair with shampoo to remove the onion juice and any residual scent. Therefore, the shampoo is used after the onion juice treatment, not simultaneously.
Here's how the process generally works:
- Prepare the onion juice mixture: While pure onion juice can be used, it's often mixed with other ingredients to reduce the strong odor or add beneficial properties.
- Application: Apply the mixture to your scalp and hair.
- Wait: Leave the mixture on for approximately 20-30 minutes.
- Shampoo: Gently wash your hair with shampoo to remove the onion juice.
