Straight hair is the hair type that is most susceptible to split ends, or ends that look frayed, dull, and dried out. Combat split ends by getting your hair trimmed regularly, or every 4-6 weeks.  If trimming that often is not possible for you, try other techniques to prevent split ends such as lessening how often you blow-dry, brushing and combing your hair less frequently, and not combing your hair when it's wet. If you're handy with scissors on your own hair, you can also try trimming your own split ends. Sometimes split ends are inevitable on straight hair. To hide them, style your hair in a bun or a braid. If your hair is too short for a bun or braids, try using small clips to twist your hair in several places all over your head instead. Straight hair can often look like it lacks volume and bounce. If you'd like your hair to look thicker or bouncier, ask your hair stylist for a layered cut or a bob. If you like having long hair and a bob is too intimidating to you, your stylist can give you suggestions on what type of layered cut would look good on you. Check out pictures online or in style books at the hair studio to get more ideas for layered cuts and bobs. While blow-drying your hair too frequently can dry it out, an blow-dry on thin straight hair can work wonders for adding temporary volume. After you wash and condition your hair, stand with your head down and use a round brush as you apply the air to your hair while it's upside-down.  Apply a pea-sized amount of lightweight mousse near your roots for an extra volumizing effect if you're trying this technique. If you notice that your hair starts becoming dry or damaged, reduce the number of times you blow-dry to 1-2 times per week and add a heat-protectant to your hair before blow-drying. Lowering the temperature setting on your blow-dryer can also reduce damage. Another way to add temporary volume to your hair is by adding waves to it. Get natural waves in your hair by braiding it when it's wet for the best effect, though braiding it when it's dry works too.  Sleep with your braids in overnight and take them out in the morning to see the new waves in your hair. Make sure your braids are dry before you unravel them. If they're not, you can use a hair dryer on them. Lots of product will weigh down most straight hair. When you need to use these products, use small, pea-sized amounts of gel or mousse, or a few quick squirts of spray, and use ones that are labeled as volumizing or lightweight. Products with alcohol in them can contribute to dry hair. Alcohol is most often found in hairsprays and some gels. Try to avoid using products containing alcohol.

Summary:
Get your hair trimmed every 4-6 weeks to remove split ends. Wear your hair in a bun or braids to hide split ends. Try a layered haircut or bob to give your hair volume. Add volume by blow-drying your hair upside-down. Try braiding your hair at night to add waves. Use gels, mousses, and hairsprays sparingly.
