Age changes your hair texture by affecting how the hair follicles grow the hair. As you age, the follicles may grow hair more slowly, resulting in straighter hair. In the same way that pigments are lost with age, resulting in gray hair, the slowing of the follicles can cause hair to fall out, and grow back more coarse. Women may find their hair changes with menopause in a more advanced age. The effect that age has on hair growth and texture has not been deeply studied, and there are still lingering questions in the medical community about how exactly hair changes with age.
Your hormones will ultimately play a large part in the texture of your hair. You may find that the greatest changes in your hair occur with the greatest surges in hormones; puberty, pregnancy and menopause. This is partly because of the effect your hormones have your thyroid, says Tom Dawson, a principal scientist at P&G Beauty. Hormones that are produced by the thyroid can cause hair to become drier and more brittle over time, while a large amount of hormones during pregnancy can render your hair to be smoother and shinier.
What you eat will cause your hair texture to change, especially if it is a sudden change. Those who consume a diet high in vitamin E and omega-6 fatty acids will enjoy smooth and shiny hair, notes the University of Maryland Medical Center. Those who consume a diet low in nutrients, or who drink a lot of alcohol may find that their hair feels dry and coarse. Like any other organs in your body, your hair will need sufficient nutrition to be at its healthiest. A multivitamin can help you gain smoother hair after a texture change has occurred for the worst.
Chemotherapy can wreak havoc on an individual's hair texture. Most chemotherapy patients find that they lose their hair 10 to 14 days after starting treatment, says the Mayo Clinic. When their treatment is complete and the chemotherapy ends, the hair follicles are still left changed. Many chemo patients find that their previously straight hair grows in curly, due to the altered hair follicles following chemotherapy. Hair texture may return back to normal after regrowth, while some learn to live with their new hair texture over time.
