The average woman makes hairstyle changes up to 104 times in her life! It may be a subtle change like a trim, color, or layers, or more dramatic changes. Women know that changing their hair has maximum visual impact over other style changes.
Reasons for change? Boredom with the same style, a life change or milestone (birthday, birth of child, break-up, divorce), desire for more self-confidence.
Set some rules for yourself like waiting a week before taking the plunge to see if you still want to. By then you will have the right tools and some time to look at pictures, products, and to visualize your new style.
