There are a variety of things you can do to help prevent hair loss and promote healthy hair growth. 
Nutritional Changes
Eating a balanced and nutritious diet is essential for healthy hair. Make sure to include plenty of proteins, vitamins, and minerals in your everyday meals, such as omega-3 fatty acids, iron, zinc, and biotin. Eating foods with these nutrients can help promote hair growth and reduce hair shedding.
Reduce Stress
Stress can be a major factor in hair loss and thinning. Finding ways to manage stress, such as through exercise, yoga, and meditation, can help reduce hair loss.
Avoid Certain Habits
Certain habits can lead to hair loss, such as tight hairstyles, excessive styling, and excessive heat treatments. Try to avoid these habits and opt for more gentle treatments, such as air drying or using heat protectants.
See a Doctor
If you are experiencing excessive hair loss, it is important to see your doctor. They can help diagnose the underlying cause of your hair loss and provide treatment options.
