It comes to most by the end of thier 30s the dreaded grey hair a sure sign of aging but because you know you have some grey it does not mean others have to know. Follow this advise
GREY HAIR If you only have a little grey a semi-permanent colour wash (stays for six to eight washes) will cover it. For more than 30 per cent grey then a quasi colour covers grey whilst keeping a natural look. When you go grey in patches, a permanent tint or a foil and tone technique - where highlights are woven around the top and crown and a semi-permanent colour is put through the rest of the hair - is the only way to cover up. This creates warmth and depth throughout the hair.
