Q: I am currently getting a full set of highlights every four weeks, and it's starting to get a little bit pricey. 

It seems as if my roots never completely disappear for longer than two weeks. In these pictures, I had just recently had my hair highlighted. 

I really want to get the same light blonde, almost platinum hair colour at home.

I don't mind going to the salon every so often so I can get the dimensional look of highlights–I just want something to hold me over a little longer, and that looks like it matches the colour I have now. 

My hair is naturally a dark, mousy blonde that pulls brassy. I am happy going lighter too, if that helps. Can you help a desperate girl out? — Hope

A: Hope, thank you for your question.

The blonde suits you very much.

The best way to deal with the re-growth is to get the shade 12-11 from the Schwarzkopf Professional Igora Royal range. 

Mix it with 40 volume peroxide, and leave it on your hair for 45 minutes before shampooing out.

Be very careful with your application. DO NOT go over the already-lightened hair—only the dark, mousy hair.

Your end result should be a very light platinum blonde and no brassiness. Enjoy!
