1. Eat right.
"It may seem unrelated, but what you eat, or don't eat, has a huge impact on the health of your hair, especially as it ages. There are a number of hair super-foods that can nourish your strands and improve your hair's length, shine and thickness, including salmon, which is loaded with protein and omega-3 fatty acids, dark green vegetables for vitamins A and C, and nuts, which are a terrific source of zinc. Protein is also essential for healthy hair."
2. Change your styling habits.
"As the hair ages, women tend to do more styling, which disrupts and damages the cuticle and makes the hair dull and more prone to breakage. Other frequent mistakes include over-washing your hair, which can strip the oils from your hair and contribute to dryness, and overuse of hair extensions which can put traction on the follicles leading to poor hair growth,".
