Wella Welloxon Perfect Cream Developer - 12%

The 12% (40 Volume) developer is primarily used for significant hair lightening, achieving maximum lift when coloring or bleaching.

While technically possible, it's generally recommended for experienced professionals only due to the high volume, which can cause irritation or damage if not used correctly. Always follow specific product instructions and perform a patch test.

Processing time varies greatly depending on the specific Wella color or lightener product used, the desired result, and the client's hair type and condition. Always refer to the instructions on the color/lightener packaging. Monitor the hair closely during processing.

It is best suited for virgin hair or hair that can withstand significant chemical processing. It should be used with extreme caution on fragile, damaged, or chemically treated hair, and a strand test is highly recommended.

The 12% volume provides the highest level of lift among the Welloxon Perfect developers, making it suitable for drastic lightening. Lower volumes (e.g., 4%, 6%, 9%) offer less lift and are used for depositing color, covering gray, or achieving subtle lightening.

The 'Me+' molecule in the New Koleston Perfect is a component designed to reduce the risk of developing a new hair dye allergy. Welloxon Perfect is the recommended developer to be used with this reformulated Koleston Perfect.

Accurate mixing ratios, even application, and precise timing are crucial. Always use with Wella Koleston Perfect, Magma, or Blondor as intended, and perform a strand test to predict the outcome and check hair condition.

This can occur if the 12% developer was left on too long or if the starting hair color was very dark. Ensure accurate timing and consider using a lower volume developer for less lift or a toner to neutralize brassiness.

This is often due to prolonged contact or individual sensitivity. Ensure gloves are worn, avoid applying directly to the scalp for extended periods, and rinse immediately if discomfort occurs. Do not use on irritated or broken scalp skin.

Thorough mixing and precise application are key. Ensure the developer and color/lightener are fully combined and applied evenly section by section. Check for adequate saturation of the hair strands.

The high lift of 12% developer can impact hair integrity. Always follow up with a deep conditioning treatment or mask. Ensure the hair was in good condition prior to the service and consider strand testing.
