Give your hair the right amount of vitamins. Since hair is made of proteins, eat a balanced diet rich in lean protein, whole grains, fruits and vegetables. A healthy diet will ensure hair that looks and feels better. Give your hair some time to show new brilliance. What you eat will not have an immediate difference on the hair you already have, but it will help with hair that is newly growing.
Drink at least 8 glasses of water or other fluids every day to keep your body hydrated. Additionally, you can enjoy foods like soups, fruits, and vegetables, which helps keep your body — and your hair — healthy. Water is the best choice, but you can also keep hydrated with tea, juice, and other beverages.
C：Remove stress from your life.
Physical and mental stressors will keep your hair from realizing its full potential. Stress can cause hair loss, so try not to let stress overcome you. Please finding healthy emotional outlets for your stress: yoga, biking, meditation, or other forms of exercise all work well.
D：Do not stay up late.
Not getting enough sleep, or prolonged lack of restful sleep, can lead to a variety of negative impacts on one’s physical health.
The increased levels of stress that result from the lack of sleep, and the reduced capacity for normal cellular functioning, may result in conditions of hair loss or thinning hair as well.
E：Avoid sun exposure.
Wear a hat or cover yourself with an umbrella. If your hair has prolonged exposure to the sun, UVA and UVB rays can damage the outside cover of the hair strand, called the cuticle.
Signs of sun damage to your hair include discoloration, dry and brittle strands, broken or split ends, thinning and frizziness.
F：Wear a swimming cap
If you swim in a chlorinated pool, please wear a swimming cap to protect your hair, then make sure you rinse the pool water out of your hair with clear water after you swim.
