4. Vitamin C
As you get older, your body is more susceptible to the damage caused by free radicals and your hair is no exception. Free radicals are the toxins and internal pollutants that cause damage to and age your cells on a micro level. This damage is gradual and so is the reversal process. The challenge when your age is that antioxidative enzymes also decrease. These enzymes fight off free radicals. Fewer of these enzymes can, therefore, mean hair that looks aged, grey, dull, limp, thin, and broken down.
Getting a good intake of vitamin C can help your body defend itself – and your hair structures – from free radicals. You’ll find these superhero defenders in oranges, grapefruit, limes, lemons, peppers, kale, kiwi, strawberries, broccoli, and Brussel sprouts. Alternatively, take 500mg to 1000mg twice a week in supplement form. Changing the diet can improve things dramatically and taking this vitamin is just about incorporating it into your daily diet.
