When your hair does not receive or keep enough moisture, it becomes dry. It loses its luster and might appear frizzy and lifeless as a result. Dry hair can affect men and women of any age, but as you get older, you’re more prone to get it. There are three layers to your hair. Natural oils in the outside layer of good hair help protect the inner layers. They also reflect light, giving your hair a lustrous appearance. The sheen and gloss of your hair are two crucial indicators of its health. The outside layer of your hair breaks down as it dries, making it appear drab and unhealthy. Make an appointment with your doctor if you have severely dry hair that does not improve with adjustments to your hair care routine. They might be able to figure out what’s causing the problem. They may also recommend you to a dermatologist, a specialist in skin and hair problems. They’ll probably look at your hair and scalp. They may prescribe one or more tests in some circumstances. They might take a sample of your blood or urine to look for evidence of hypothyroidism or hypoparathyroidism, for example.
