Balayage is a French term - a technique for highlighting hair in which the colour is painted on in such a way as to create a graduated, natural-looking effect.
Blondes- this technique is great depending on how naturally light or dark you are.
You can go 12-16 weeks if you are naturally light.
If you are naturally dark, balayage will be a great option for you but if you want to be quite blonde then you will need to maintain it every 6 weeks.
If you have white hairs you can mask them with a semi permanent
You can add vibrant colours on top of your balayage- Reds, Coppers, Purples, Pinks
