4 Fill Formula Steps To Use ASAP! 

If your blonde clients are ready to embrace the darkness—by becoming a brunette—there is one step to NEVER skip. Filling the hair, or repigmenting the hair, is important for avoiding a hollow tone and creating a long-lasting finished result.

1. Find Their Natural Starting Level 

Split the hair down the center back and check out the regrowth area to determine the client’s natural starting level. “This area hasn’t been seen by any sun so it will give you the best representation of their natural starting level,” Mirella explains. This is helpful in formulating a root shade and will give you an idea of the underlying pigment of their natural level.

 

Pro Tip: Use a swatch chart to help determine the exact starting shade. Mirella suggests fanning the swatch out and placing it right onto the regrowth area for an accurate swatch test.  via Instagram @mirellamanelli

 

2. Formulate Missing Pigments 

Use a color wheel to determine the underlying pigment of the desired end shade. Since her client was requesting a Level 6, Mirella needed to replace the orange and gold pigments that were lost during lightening. 

 

Pro Tip: Mirella’s fill formula was 75 percent gold and 25 percent copper. This will replace the missing orange pigment, creating a rich brunette shade. If the client was requesting a more vibrant red, Mirella suggests mixing 75 percent copper to 25 percent gold.

3. Avoid Blotchy Results With Demi-Permanent Color 

“Using a demi-permanent for filling is vital because usually when dealing with previously lightened hair, we are dealing with high porosity,” Mirella explains. The Kenra Color demi-permanent line contains low ammonia, which is more gentle and will create a more even result for applying a gloss or final shade.

4. Don’t Make These Mistakes! 

Avoid these mistakes to streamline color services and save time, money and sanity! 

 

  • Not adding red or copper to fill formulas. Excluding warm tones from a formula can create a muddy finished hue. Even if the client is requested a cool or ash tone, adding red or copper will allow the ash to control the warmth and create a vibrant result.

 

  • Don’t rush or skip the fill process. Be patient and only fill two levels at a time, Mirella suggests. Filling the hair helps color last longer and is crucial for avoiding hollow color. So take your time and let the client know (especially if it is a color correction!) that this is part of the process.
