The Sexy Hair products are what I use when I do style my hair(not very often) but I do use the "spray and play" spray for a quick up-do between washes. I have fine hair so it does get greasy and limp fast. But I still only wash about 2-3, 4 times at the most a week. I have found the less you wash and touch your hair through the day the less oily it becomes with time.
I love Redken! I have been using the All Soft for years, I don't color my hair otherwise it would most likely dilute your color. But I have heard good things about Color Extend like Beau uses.
Something else to consider, when using salon quality products you do not need a whole lot to get the job done. The initial price may be hard to swallow but the product lasts quite a while making the money well worth it and having better hair as a result.
