Problem: Article: Sodium laureth sulfate and sodium lauryl sulfate are common ingredients in shampoos and conditioners, but sulfates can damage hair and cause frizz. If your current products include these ingredients, replace them. Look for new products that list glycerin as one of the top ingredients, since glycerin can deeply hydrate and protect your hair. Avoid shampoos that advertise as “clarifying” – these will strip moisture from your hair.  Check product labels for words like “smoothing,” “moisturizing,” and “frizz-reducing.” Look for hydrating ingredients like Argan oil, keratin, avocado oil, vitamin E, Moroccan oil and coconut oil.  Avoid hair products, including shampoos, conditioners, gels, and hairsprays, that contain alcohol, which can dry out and damage your hair. Wavy hair requires more moisture than straight hair to combat frizz. After shampooing, apply a rich deep conditioner for a boost of hydration. Don’t skimp on the conditioner – apply plenty of it. Then run a wide-toothed comb through your hair to distribute the conditioner evenly. Leave the deep conditioner on for at least five minutes.  Look for deep conditioners that contain ingredients like shea butter, glycerin, coconut oil and Argan oil. If your hair gets weighed down too much by deep conditioner, avoid applying it to your roots. Try applying it from the mid-shaft down to the ends. This is also a great way to detangle your hair. Cold water will smooth and close the hair cuticle, which helps to prevent frizz and adds extra shine. Right before you get out of the shower, rinse what’s left of the conditioner out of your hair with the coldest water you can tolerate. Avoid using the wide-toothed comb during the rinse, since at this stage it can damage your strands. Terrycloth fibers cause friction on hair strands, which creates frizz. Switch from terrycloth bath towels to microfiber towels for your hair. Microfiber towels absorb water better and faster than traditional terrycloth towels, and they don't disrupt the hair's natural wave. Flip your hair upside down, wrap it in the microfiber towel and gently squeeze the water from your hair.  Start at the roots and work your way down to the ends. Be gentle with your wet hair. Never rub at or use rough motions on your hair with a towel, which will disturb the hair cuticle and create frizz. Blow drying wet hair can damage it and cause significant amount of frizz. Blow dryers focus a lot of hot air on your strands and this will dehydrate your hair, especially if you live in a dry climate or during the winter when there’s less humidity in the air. Let wavy hair air dry 90 percent of the way and then use your blow dryer to dry the remaining 10 percent.
Summary: Shampoo and condition with sulfate-free products. Use a deep conditioner after every shampoo. Rinse out the conditioner with cold water. Avoid terrycloth towels. Allow your hair to air dry 90 percent of the way before blow drying.

Problem: Article: Plyometrics incorporate jumping movements and strengthen the muscles. This type of exercise also increases the speed and agility you need for most sports. Do these exercises to help get your body used to quick movements and using a lot of power. You need to land lightly while doing plyometrics so that you catch your weight on the balls of your feet. Roll back to your heel, knees slightly bent and hips straight. You will hop over a cone to increase strength and control of your MCL. Practice doing several sets of 20 reps. Stand with a 6 inch cone to the left and hop to the left over the cone landing softly as described in the plyometrics step.  Repeat this with the cone to your right, hopping to the right. Now, jump forward over the cone. Practice jumping backwards over the cone too. Do not snap your knee back to straighten it. Keep your knees stable. You should practice hopping over the cone with one foot, doing 20 reps. This will further increase the power, strength and control you have over your MCL. Hop forward and backward over a 6 inch cone, landing lightly on the balls of your feet and maintaining a slight bend at the knee. Switch feet and practice hopping over the cone with the other leg. Do 20 reps of the scissors jump to increase strength and power. This will help significantly with jumping during sports. Make sure your knees are stable during this exercise, and do not allow your knee to cave in or out.  Use your right leg to lunge forward, keeping your knee directly over your ankle. Push with your right foot so your left leg moves into the lunge position. Sprinting trains your knee, ankle and hip to remain stable during sudden movements. This increases strength and agility. Practice shuttle runs regularly to maintain speed, strength and dynamic stability. Start at a cone and sprint forward to a second cone, a short distance away. Run backwards to the third cone and forward to the fourth. Practice going forward and backwards from cone to cone. Diagonal runs are basically shuttle runs that focus on the outside of each leg and foot. This stabilizes the knee, ankle and hip complex. It also increases agility and makes your MCL stronger.  Run to a cone placed to your left. You will want to pivot off the left foot as you run to the next cone. Pivot off your right foot to the next cone. Maintain proper form and don't allow your knees to bend inward. Always keep your knees slightly bent so they are directly over the ankle joint. A bounding run involves running across 44 yards. You will start at shorter distances and increase your distance over time with practice. This exercise has multiple benefits, increasing flexibility, strength, power and speed. You will want to begin along the sidelines. When you run, push your knees high up toward your chest. As your legs come down, land on the balls of your feet. Your hip needs to be straight and knees slightly bent.
Summary:
Do plyometrics. Practice hopping over a cone. Do single leg hops over the cone. Perform the scissors jump. Do shuttle runs. Practice diagonal runs. Do bounding runs.
