Classically long straight hair can look good at any age. The key thing to remember is the texture of your hair. If you are thinning, either on top or in dimension, do not try to pull off long hair. Long stringy, drab hair looks terrible on anyone. But as long as you have a healthy head of hair, long straight hair can look mysterious, handsome and sexy! Be sure to keep your mane looking healthy by regularly washing and conditioning with moisturizing products. Regular trims are also important, as you will be susceptible to split ends that lead to breakage of the hair. Less is more in styling your hair so use just a simple leave-in cream conditioner that is lightweight and focused on the ends. Make sure your hair products smell good as you can be guaranteed that admiring hands will find their way to running through your longs strands.
