Ensure the product was applied evenly throughout all sections of your hair. Verify that the processing time was strictly followed as per the instructions. Hair's porosity and previous treatments can affect the final shade; always refer to the shade guide on the packaging for expected results on your specific hair colour.

If you experience any burning, stinging, or rash, rinse immediately and discontinue use. This is why the 48-hour patch test is crucial before every application to identify potential allergic reactions.

Ensure you are using colour-safe shampoos and conditioners. Avoid washing your hair too frequently, and protect your hair from excessive sun exposure or chlorine, which can strip colour.

While Olia is formulated to improve hair quality, some hair types may still require extra care. Ensure you used the provided conditioner. Incorporate a deep conditioning treatment or hair mask into your routine once a week to maintain moisture and health.
