To avoid hot roots (unwanted warm or brassy tones) on gray hair, use a toner with cool tones to neutralize the warmth. This balances the color and prevents that uneven look.
Understanding Hot Roots on Gray Hair
Hot roots are a common problem for those with gray hair who color their locks. The new hair growth is often a different color—more yellow or brassy—than the already colored hair. This results in a noticeable difference between the roots and the rest of the hair, an effect we call "hot roots." This is particularly challenging because gray hair can already have underlying warm undertones which are intensified by the oxidation of the hair coloring process.
Solutions to Prevent Hot Roots
Here’s how to mitigate the problem:
-
Use a Cool-Toned Toner: As mentioned, this is the key. A toner deposits cool tones to counteract the warm tones. Look for toners specifically designed for neutralizing brassiness or yellowing. [Find a reputable salon or stylist to assist in the selection process].
-
Blend Warm Colors with Neutrals: If you desire warmer tones in your overall hair color, blending your chosen warm or bright color with a neutral shade helps achieve a more even and consistent result throughout, minimizing the contrast of the roots. This reduces the chance of the new growth appearing overly warm compared to the pre-colored hair.
-
Regular Touch-Ups: Frequent touch-ups, every 4-6 weeks depending on your hair growth rate, can help prevent a large difference in tone between roots and colored lengths. This makes the transition less drastic.
-
Consider a Demi-Permanent or Semi-Permanent Color: These options provide less coverage than permanent dyes but are gentler and tend to fade more gradually, reducing the starkness of root regrowth.
Example: Imagine your gray hair has a slightly yellow undertone. To prevent brassy roots when you color, a toner with ash or violet undertones will neutralize those yellows and keep your roots cool and even with the rest of your color.
Important Note: Always perform a strand test before applying any toner or color to your entire head. This helps you see how the product reacts with your hair and prevent unexpected results. If unsure, always consult a professional hairstylist.
