It is important to use purple shampoo in moderation on strawberry blonde hair, as it can be drying and may cause the color to appear too cool if used too frequently. For best results, use purple shampoo once or twice a week.
Leave the shampoo on the hair for 2-3 minutes before rinsing it out thoroughly. Be sure to avoid the ends of the hair, as they are more prone to drying out. Squeeze a small amount of the shampoo into your palms and work it into the hair, focusing on the roots and mid-lengths. To use purple shampoo on strawberry blonde hair, start by wetting the hair in the shower. Purple shampoo works by counteracting warm tones in the hair, so it can be particularly effective at neutralizing yellow tones that can sometimes appear in blonde or light red hair.
Purple shampoo can be used to tone strawberry blonde hair to help neutralize brassy or yellow tones and add vibrancy to the color.
