Hair colourants can cause severe allergic reactions in some individuals. The 48-hour skin allergy test is a critical safety measure required before *each* use to help identify potential reactions and prevent serious harm. Always perform it as directed.

Garnier Olia is a permanent hair colour. This means the colour will not wash out but will grow out with your hair. Longevity can also depend on hair care routine and exposure to elements like sun or chlorine.

Garnier Olia is formulated for optimal scalp comfort. However, individual sensitivities vary. It is absolutely essential to perform the 48-hour skin allergy test every time you intend to use the product, regardless of previous experiences.

Colour results can be influenced by your current hair colour, porosity, and previous treatments. Always refer to the shade guide on the packaging. If the result is significantly different or undesirable, it is best to consult with a professional hairstylist for corrective measures.

Immediately rinse hair and scalp thoroughly with water. Seek medical attention if symptoms persist or worsen. Always perform the 48-hour skin allergy test before each use to prevent such reactions.

Colour results can vary based on your natural hair colour, previous treatments, and hair porosity. Always check the 'before' and 'after' shade guide on the box. For significant correction, consult a professional hairstylist.

While Olia is designed for optimal scalp comfort, individual sensitivity varies. Ensure the 48-hour allergy test was performed. If discomfort is severe, rinse immediately. Do not continue if irritation persists.
