In one sentence, describe what the following article is about: Healthy hair starts with a healthy diet! Eat foods rich in vitamins that promote hair growth as often as you can. For instance, eat dark, leafy greens like spinach and broccoli for a source of vitamins A and C. You can also eat foods like salmon, eggs, avocados, sunflower seeds, almonds, yellow peppers, and sweet potatoes.  Sweet potatoes help retain vitamin A, sunflower seeds are rich in vitamin E, and yellow peppers are rich in vitamin C. Almonds have a high biotin and protein content. Salmon is rich in vitamin D and protein, eggs contain biotin and omega-3, and avocados have a high concentration of essential fatty acids. These vitamins encourage hair growth and thickens the hair follicle. You can look for a multivitamin with all of these listed, choose a “hair, skin, and nails,” vitamin, or purchase them individually. For best results, take time first thing in the morning, following the specific directions. It may take a few months to see results, but over time, taking these vitamins regularly may result in longer, thicker, healthier hair. Your skin will also look great too! You can easily snip your ends yourself or get a trim at a salon. Routinely trimming your ends keeps your hair healthy, removes split ends, and revitalizes the follicle. Removing any split ends gives the appearance of long, thick hair. If you don't trim your ends, the split could move upward and eventually cause the whole strand to break off. While your hair grows, it is helpful to get a keratin hair treatment every 1-3 months. Keratin is the protein your hair is made of, and keratin treatments coat the hair with a protective layer of protein. This avoids damages and smooths out your hair texture, so you don’t have to use styling tools as often. You can either purchase an at-home keratin treatment or schedule an appointment with a stylist. A keratin treatment should be repeated every few months.  This is great for chemically straightened or colored hair. It's also a favored treatment among those with curly hair because it helps to keep curls manageable. Some keratin treatments contain formaldehyde. Talk to your stylist about finding a treatment that is safe for you. Cotton pillowcases are rough on your hair and often take the moisture out of your hair. Switch to a silk or satin pillowcase to reduce friction and retain moisture. This, in turn, prevents damage to your hair.  You can find silk and satin pillowcases at home supply retailers or online. Silk and satin pillowcases also help avoid breakage and tangles. The less your hair breaks, the longer it will be. Silk pillowcases work the best, though satin pillowcases are a more affordable option. When the cuticle of your hair is exposed to chemicals from hair dyes, bleach, or relaxers, it gets dried out and damaged. If your hair is dry, it is much easier to break or to get split ends. Limit the chemical treatments to grow your hair as long and thick as possible. If you want long, thick hair but your hair is thin or fine, consider investing in a hair regrowth treatment. You can purchase these at beauty supply stores and do them yourself, or you can find a stylist online and schedule an appointment. Hair regrowth treatments preserve the hair you have and help promote new hair growth. Before you pull the trigger on a hair regrowth treatment, it is helpful to do some research online. These are often made with chemicals, and the only FDA-approved drug to treat hair thinning is Minoxidil.
Summary: Eat a healthy diet full of vitamin A, C, D, zinc, and protein. Take vitamins like biotin, vitamin B, and vitamin C. Trim your ends about 1⁄4 in (0.64 cm) every 4-6 weeks. Get a keratin treatment every 8 weeks to moisturize your hair. Try using a silk or satin pillowcase to protect your hair. Avoid using hair dyes and relaxers to prevent damaging your hair. Try using a hair regrowth treatment if your hair is thinning.

Problem: Article: In many go-karts, you can only brake with your left foot. Other go-karts give you the option. Either way, braking with your left foot can give you a split-second advantage over other drivers. Breaking with your left foot saves you the time that it takes to switch from the accelerator to the brake and vice versa. If you're used to driving a car, you typically brake with your right foot. That means it's going to take some practice to become proficient at braking with your left foot. Spend some time practicing on the track before you race. Go out on the track when there are few cars, and consciously think about using your left foot to brake. Place it on the brake throughout your drive so you remember to use it. If you can't seem to get the hang of it, switch back to braking with your right. If you're only so-so at braking with your left, then that's worse than just doing it with your right. If you're jerky with your brakes, you're just going to slow yourself down. Slowly press down on the brake in 1 smooth motion, and then release as needed. In other words, don't punch the brake multiple times to slow down.
Summary:
Work on left-foot braking. Practice with your left foot to get better. Hit the brakes as smoothly as possible.
