  4. Let it process – Once the color is applied, allow it to process for the full development time. Check directions based on hair type.

How Long Does Clairol Soy 4plex Liquicolor Last?

Clairol Soy 4plex Liquicolor is designed to be a permanent hair dye. Results will last through about 28 shampoos, or 4-6 weeks, before fading or growing out. Permanent color will not wash out of the hair. The dye molecules penetrate and alter the structure of the hair until cut or grown out.

To make the color last longer:

  • Use sulfate-free shampoo and cool water when washing
  • Use a conditioning mask or treatment weekly
  • Protect hair from sun exposure with a hat
  • Avoid using hot tools excessively
  • Use a color-protecting shampoo and conditioner
  • Get a gloss or glaze treatment around 4 weeks post-coloring

Does Clairol Soy 4plex Liquicolor Damage Hair?

Clairol Soy 4plex causes less damage than traditional permanent hair color since it does not contain ammonia. However, all permanent dyes can cause some damage since the process alters the hair’s structure. The soy proteins and aloe in the Clairol Soy4plex help counteract some of the potential drying effects.

To limit damage when using Clairol Soy 4plex Liquicolor:

  • Do not over-process and exceed the maximum development time
  • Use the included conditioner or a hair mask after rinsing
  • Wait 4-6 weeks between colorings
  • Use a gentle, moisturizing shampoo and conditioner
  • Avoid heat styling when possible
  • Get occasional deep conditioning treatments
  • Use a heat protectant if blow drying or using hot tools
  • Get trims regularly to remove damaged ends

Can You Mix Clairol Soy 4plex Liquicolor Shades?

One of the great benefits of Clairol Soy 4plex Liquicolor is that the shades are intermixable. You can mix varying ratios of two or more shades to create a custom color.

Some examples of mixing Clairol Soy 4plex Liquicolor include:

  • 1 part 5R + 1 part 6R = Vibrant red-copper
  • 1 part 6N + 1 part 7N = Neutral medium brown
  • 1 part 5N + 2 parts 6A = Ashy medium blonde
  • 1 part 8A + 1 part 10A = Light cool blonde

When mixing shades, it’s best to stay within 1-2 shade families for the most natural results. Always do a strand test before mixing shades all over.

Can You Re-color Hair with Clairol Soy 4plex Sooner Than 4 Weeks?

It is not recommended to re-color your hair sooner than 4 weeks with Clairol Soy 4plex Liquicolor. Coloring too soon can lead to damage or discoloration.

If you need to touch up roots or re-color hair sooner, there are a couple options:

  • Use a semi-permanent or demi-permanent color that washes out over time.
  • Get professional help at a salon for a color correction or toner.
  • Use root touch-up spray or powder to conceal until you can re-color.
  • Use hair makeup or colored dry shampoo to temporarily mask roots.

Always do a patch test if you must re-color before 4 weeks. Strand testing can help determine if hair can tolerate another permanent coloring session sooner than 4 weeks.
