Why it's a good option:
* Low Damage: Semi-permanent color doesn't contain ammonia or peroxide, so it doesn't lift the hair's cuticle. This means it's much gentler than permanent or demi-permanent color and won't further damage already processed (highlighted) hair.
* Toning Highlights: Many people use semi-permanent colors (especially those with purple, blue, or silver tones) to tone their highlights. This helps to neutralize brassiness and keep blonde shades cool and vibrant.
* Adding a Tint of Color: If you want to experiment with a new shade without commitment, semi-permanent color can add a subtle tint to your highlighted hair.
* Blending Highlights: Semi-permanent colors can help to blend harsh highlights or cover root regrowth in between salon visits.
Things to consider:
* Porosity: Highlighted hair is more porous than virgin hair. This means it absorbs color more quickly and can sometimes grab onto the color unevenly. Do a strand test before applying color all over to ensure the desired result.
* Color Choice:
* For Toning: Choose shades with violet, blue, or silver pigments to neutralize brassiness.
* For Adding Color: Lighter shades will show up more vibrantly on highlighted hair than darker shades.
* Avoid Very Dark Shades: Be cautious with very dark semi-permanent colors (like black or very dark brown). Highlighted hair is so porous that it can absorb these colors more deeply than expected, and they may be difficult to remove completely, even though they're semi-permanent.
* Application: Apply the semi-permanent color evenly to ensure consistent results. Sectioning your hair can help.
* Development Time: Follow the manufacturer's instructions for the recommended development time. Over-processing can lead to unwanted tones.
* Aftercare: Use color-safe shampoo and conditioner to help prolong the color and keep your hair healthy.
Tips for success:
* Strand Test: Always do a strand test on a hidden section of your hair (like underneath) to see how the color takes and to avoid any surprises.
* Start Subtle: If you're unsure, start with a lighter shade or less development time and build up the color gradually.
* Consult a Professional: If you're nervous about coloring your hair yourself, consult a professional stylist. They can help you choose the right shade and application technique for your hair type and desired results.
* Read Reviews: Look online for reviews of the specific semi-permanent color you're considering to see what other people's experiences have been.
* Use a Color Remover (if needed): If you're not happy with the result, consider using a color remover specifically designed for semi-permanent hair color. These are gentler than bleach.
In summary, using semi-permanent color on highlighted hair can be a great way to tone, add a subtle tint, or blend highlights. Just remember to do a strand test, choose your color carefully, and follow the instructions.
