For best results, use the shampoo regularly, ideally during every hair wash. The frequency can be adjusted based on your personal preferences and hair care routine.

Yes, but the results may vary. It's recommended to test on a small area first to ensure compatibility. The shampoo is designed to work gradually, so it may not drastically alter existing color.

While the shampoo is formulated without many harsh chemicals, it's always recommended to perform a patch test before full use, especially for those with sensitive skin.

The duration depends on the frequency of use and the length of your hair. Typically, a 200ml bottle will last for several weeks with regular use.

The shampoo is designed to be gentle, but it's always best to rinse thoroughly to avoid any potential staining. If staining occurs, it usually washes away easily.

The Dark Brown version provides a subtle color change, while Black is more effective for those with black hair.

Ensure consistent use as directed. Results are gradual and may take longer depending on hair type. Consider increasing the frequency of use if necessary.

Use a conditioner after shampooing to add moisture, particularly if your hair is naturally dry. Consider using a moisturizing conditioner.

Discontinue use if irritation occurs. Rinse the scalp thoroughly. If irritation persists, consult a dermatologist. Perform a patch test before use.
