You may love to relax in a hot, steamy shower, but all that hot water isn't doing your scalp any favors. Turn down the heat in your next shower; hot water can dry out your skin and lead to dry scalp.
Switch shampoos. It'll be hard to part with your favorite shampoo, but the results will be worth it. The next time you're strolling the shampoo aisle, pick up an anti-dandruff shampoo. Look for a shampoo that contains zinc pyrithione, also known as ZPT, to keep the dry scalp at bay as long as you use it regularly. Leave the shampoo on for five to 10 minutes so it can work its magic before you rinse it out.
Bring on the vinegar. Mix equal parts of apple cider vinegar and water and pour over your scalp. Let the mixture dry and leave it on for several hours before rinsing to help rehydrate your scalp. The vinegar won't exactly leave you smelling your sweetest, so apply it at night and let it work while you sleep. Lay an old towel over your pillow to save it from the smell.
Change your diet. What you eat affects more than your waistline. Omega-3 fatty acids kick your oil producing glands into overdrive and protect against dry scalp. Try foods like salmon, tofu, scallops, soybeans, shrimp, sardines, walnuts and flaxseed.
