The scalp is made up of a high density of terminal hair growth with sebaceous glands that provide a specific microenvironment. The scalp is significantly different than the rest of the skin. It contains a large amount of microbes. These microbes or bacteria can have negative implications on the condition of the hair. Oxidative stress is caused by free radicals in your cells. Free radicals, (unbalanced molecules) can damage cells by causing oxidation. Free radicals are created when you break down nutrients to make energy. They are also produced by environmental factors such as UV, air pollution, smoking, drinking and drug use. Sources of oxidative stress with impact on the hair include nicotine smoking, UVR, inflammation from microbial pollution, and oxidizing hair coloring.
Oxidative Stress is very commonly present in conditions such as psoriasis, atopic dermatitis, seborrheic dermatitis, dandruff and alopecia.
Antioxidants and their Benefits
Antioxidants work by using agents that can remove oxidants to stimulate natural detoxification. Vitamin C, is the most abundant antioxidant in human skin. Ascorbic acid neutralizes free radicals and protects the skin from oxidative stress. Vitamin E is a fat soluble compound that also helps protect the cells. Resveratrol is a polyphenolic compound found in various plants. It has antioxidant and anti-inflammatory properties.
Antioxidants can protect your health by fighting oxidative stress. You can find antioxidants in foods, spices and vitamins. Reduce the effects of oxidative stress by including the following in your diet.
• Vegetables and Fruits (broccoli, carrots, blueberries)
• Nuts (brazil, walnuts, pecans, almonds)
• Beans (kidney, pinto)
• Fish (salmon, halibut)
• Tea (green, herbal)
