You must proceed very carefully when making a big change with the color you are born with. You should enlist the services of a professional and keep a realistic end result in mind. The lighter the shade the more maintenance is involved; this means time and money. After discussing your options and desired look, the basic maintenance is as follows:

For all-over color, retouching is needed about every 4-6 weeks, although the roots may begin to show as early as 1-2 weeks. (Gwen Stefani is a good example.)

For highlights, 8-12 weeks is sufficient for touch-ups, but it may be sooner depending on how light you go and how many you have put in. (Penelope Cruz is an example of a dark brunette using Dark Blonde as a highlight. Elizabeth Hurley is another example but her hair is a Medium- Light Brown.)

Another option for going Blonde is a base color with highlights. This is when you lighten your natural color with all over color and then add highlights to the newly lightened base. The touch up is every 4-6 weeks for all over color and the highlights are added every 8-12 weeks.

For at home care you need to maintain the health of the hair with good quality moisturizing shampoos and conditioners. For course or thick hair, we recommend Frederic Fekkai Moisturizing Shampoo and Conditioner with Shea Butter. In the case of fine or thinner hair we recommend Frederic Fekkai
