Bad hair days can certainly put a damper on one's mood. You get up one morning and your hair just will not do what it normally does. You finally give up and throw it into a ponytail, or pull an old ball cap over your unruly hair. What causes this terrible styling nightmare?

Number one on the list is hair product build-up that can occur over time. The ingredients in our best loved shampoos and conditioners can stick to the hair and refuse to be rinsed out and so each time a little more product builds up. This can weigh the hair down and cause it to look greasy, stringy, or unruly. The solution is to use a shampoo that is designed to remove this excess product. It is important not to over do with this type of shampoo as it can be stripping.

For women, another culprit is hormone production and estrogen is on the rise during certain times of the cycle which can cause excess oil. This can cause the locks to look limp and lifeless. During this time try washing hair a little more often or even two go arounds instead of of one.

Let's not forget about dry, hot, humid, wet, or cold weather. Changes in climate can make a huge difference. It may be necessary to alter your regime during these environmental challenges.
