## Step-by-Step Maintenance Routine ### 1. Use Sulfate-Free, Color-Safe Shampoos Traditional shampoos often contain harsh sulfates that strip away artificial color molecules and natural oils. To maintain the rich brown and red tones, always choose a sulfate-free, color-safe shampoo. These formulas gently cleanse the scalp and hair without opening the cuticle excessively, which helps lock in the red pigments. ### 2. Manage Brassiness with the Right Toning Products Toning is one of the trickiest parts of maintaining this color combination. * **For the blonde highlights:** Purple shampoo neutralizes yellow tones. However, applying purple shampoo all over your head can dull the warmth of your reddish-brown base. To avoid this, apply purple shampoo specifically to the highlighted sections, or limit its use to once every two weeks. * **For the brown and red base:** Blue shampoo neutralizes orange tones in brown hair, but it can also dull red tones. If your goal is to keep the red vibrant, avoid blue shampoo. Instead, use a color-depositing conditioner formulated for auburn or copper hair once a week to deposit fresh red tones back into the hair. * **The safest option:** Use a gentle, color-protecting shampoo for daily washes, and rely on a professional gloss or glaze at the salon to refresh all the tones simultaneously. ### 3. Wash with Cool Water Hot water opens the hair cuticle, allowing the red dye molecules to escape down the drain. Always wash and rinse your hair with lukewarm or cool water. Cool water helps seal the cuticle, locking in moisture and color while adding a natural shine to both the dark and light tones.

### 4. Limit Washing Frequency Every time you wet and wash your hair, a small amount of color fades. Try to limit washing your hair to two or three times a week. On off-days, use a high-quality dry shampoo to absorb excess oil at the roots without stripping the color from your mid-lengths and ends. ### 5. Apply Heat Protectant Before Styling Heat styling tools—such as blow dryers, flat irons, and curling irons—can rapidly fade hair color and dry out highlighted strands. Always apply a lightweight, color-safe heat protectant spray or serum before using any hot tools. Keep the temperature settings on your styling tools at a medium or low level to prevent scorching the blonde highlights and fading the red base. ### 6. Protect Hair from UV Rays and Chlorine Sun exposure acts as a natural bleaching agent, fading red tones quickly and turning blonde highlights brassy. When spending time outdoors, wear a hat or apply a leave-in conditioner that contains UV filters. Additionally, wet your hair with clean tap water and apply a leave-in conditioner before swimming in chlorinated pools to prevent the hair from absorbing chemicals that can turn blonde highlights green or muddy. ## Professional Maintenance and Salon Visits Even with a diligent home care routine, multi-tonal hair requires professional upkeep to look its best.

* **Gloss or Glaze Treatments:** Schedule a demi-permanent gloss treatment at the salon every six to eight weeks. A gloss helps restore the vibrancy of the red-brown base, tones down any brassiness in the blonde highlights, and seals the hair cuticle for maximum shine. * **Root Touch-Ups:** Depending on how fast your hair grows and how much gray coverage you need, plan to touch up your brown-red roots every four to six weeks. * **Highlight Touch-Ups:** Blonde highlights do not need to be touched up as frequently as the base color. You can typically go 10 to 12 weeks between highlight appointments, especially if you have a blended technique like balayage. ## Frequently Asked Questions ### Can I use purple shampoo on red hair with blonde highlights? Yes, but you should use it sparingly. Purple shampoo targets yellow tones in the blonde highlights, but using it too frequently all over your hair can make your reddish-brown base look dull or ash-toned. Apply it primarily to the blonde sections, or use it only once every two weeks. ### How do I prevent the red dye from bleeding into the blonde highlights? To prevent color bleeding, wash your hair with cool water and use a color-sealing treatment immediately after coloring. When washing at home, avoid letting the hair sit clumped together while wet for long periods, and dry it promptly after washing.

### Why is my reddish-brown hair turning orange? As red and brown hair dye fades, the warm underlying pigments of the hair are revealed, which often look orange or brassy. Using a color-depositing conditioner for red hair can help restore the rich red tones, while a professional gloss can correct the unwanted brassiness.
