Ensure you correctly assessed your starting hair colour against the shade guide on the packaging. Verify you followed the processing time accurately, as under- or over-processing can affect the final result. Hair porosity can also influence colour uptake. For future applications, consider a strand test on a small, hidden section of hair.

This product is designed for optimal scalp comfort, but individual sensitivities vary. Always perform a skin allergy patch test 48 hours before each use. If irritation occurs during application, rinse immediately with plenty of water. If symptoms persist, seek medical advice.

Uneven application is a common cause. Ensure hair is sectioned thoroughly and the product is distributed evenly from root to tip. If your roots are significantly different in colour or texture (e.g., virgin hair), consider applying to the mid-lengths and ends first, then to the roots for the last 10-15 minutes of the processing time.

Ensure you used the full amount of the after-colour conditioner provided and left it on for the recommended time. Environmental factors, existing hair damage, or product buildup can affect perceived texture. Regular deep conditioning treatments can further enhance hair health.
