Okay, so you’ve done the daily flat-iron thing and the six-hour hair-frying Japanese straightening torture.  You’re so over it all, yet your frizz has you frazzled.  New hope, new products, and new lower prices to the rescue!  ISO Maintamer and Matrix’s Opti-Smooth Heat Service are two-hour salon treatments that last for six to nine months.  For $100 to $150, you get straight, deep-conditioned treatment that even color-treated hair can handle.
