Custom Purple Shampoo

A customized purple shampoo designed to gently cleanse and tone brassy hues on blonde, silver, gray, or highlighted hair - for cooler color and healthier hair, no compromises.

Key Benefits

  • Reduces brassiness and yellow tones, for cooler blonde or gray color after just one wash.

  • Protects hair from chlorine, sun, and pH-unbalanced water, and other hair aggressors, to keep color cool and hair strong and healthy.

  • Strengthens hair, improves scalp barrier and helps reduce frizz and split ends.

  • Key Ingredients

    Combined in a unique blend created just for your hair, every purple shampoo formula starts with these three ingredients:

    Neutralizing Violet Pigments

    Reduces brassiness for a cooler tone in blonde + grey hair.

    Glycerin

    Hydrates & locks in moisture.

    Betaine

    Offers care, protection, strengthening, and conditioning to hair.

    How to Use

    Lather shampoo, apply to hair, rinse and repeat. Leave on hair, especially brassy areas, for 2-3 minutes. Rinse thoroughly. For more intense results, leave in for an additional 1-2 minutes.

    Rinse your tub, shower, or sink well afterward to prevent staining.

    We suggest applying your custom purple product on a test strand of hair before using on your whole head.

    Hello purple shampoo!!!! Living in the city, the water has always been harsh on my hair. My platinum hair turns brassy soon after I get my hair done and it is very frustrating. I have tried many purple shampoos and they dry out my hair - not function of beauty. This one makes my hair bright white long after my touch ups and it is safe to use a couple times a week.
