Does yellow wash out of grey hair?

Yes, yellow tones can wash out of grey hair, particularly if the hair has been lightened or bleached. Over time, external factors like environmental exposure, product buildup, and heat styling can contribute to a yellowish tint. To counteract this, purple shampoos and conditioners can be used, as they neutralize yellow hues and help maintain a cooler tone in grey hair. Regular maintenance and proper hair care can also minimize yellowing.
