Yes, it is absolutely crucial. Always perform a skin allergy patch test 48 hours before each use, even if you have used hair colour products before, to check for any allergic reactions.

It is generally advised to wait at least two weeks after a perm or relaxer before colouring. Always consult the detailed instructions inside the box, as some chemical treatments may affect colour absorption and final results.

For very long or thick hair, it is often recommended to use two boxes of hair dye to ensure complete and even saturation of all strands for the best results.

To maintain vibrancy, use shampoos and conditioners specifically designed for colour-treated hair. Rinse with cooler water, wash hair less frequently, and consider using UV protection hair products or wearing a hat when exposed to strong sunlight.

Treat dye stains on clothing immediately. Rinse the stained area with cold water, then apply a stain remover suitable for colour-safe fabrics. Follow the garment's washing instructions. Act quickly as dried dye stains are much harder to remove.

This can happen if your hair is naturally very dark, has product build-up, or if the development time was too short. Ensure hair is clean and dry before application. Consider a strand test next time to adjust development time for your specific hair type. For very dark hair, a pre-lightening step might be needed (though not recommended for first-time users).

Uneven application is a common cause. Ensure you section your hair thoroughly and apply the product evenly from roots to ends, saturating all strands. If some areas are more porous (e.g., damaged ends), they might absorb more colour. Next time, apply to roots first, then distribute to ends for the last 5-10 minutes of development time.

This can often be prevented by applying petroleum jelly around your hairline, ears, and neck before starting. If staining occurs, try gently rubbing a small amount of rubbing alcohol or a mild cleansing wipe on the stained area immediately after rinsing your hair. Do not scrub harshly to avoid irritation.
