Human hair is stronger than aluminum, copper or nylon strands of similar size and the strength comes from its chemical constituency, made up mostly of keratin (fibrous structural proteins also found in nails and the outer layer of the skin).
There is an extensive variety of hair types, ranging from straight to wavy/curly, and it is important that an appropriate hair care is chosen for each type. As an example, curly hair is already naturally extremely dry and therefore does not require frequent shampoo treatment. Some of the many potential factors behind hair and scalp problems may be related to mechanical and chemical damage (over-styling), stress, hormonal imbalance, nutritional deficiencies, electro-magnetic field radiation, heredity, birth control pills, diabetes, weight loss, chemotherapy, parasites, heavy metals toxicity (from environmental sources, cosmetic products ).
In order to achieve healthy hair, it is important to ensure that the body is supplied with all essential nutrients such as silica, B-vitamins and biotin. This can be accomplished by addressing all nutritional deficiencies and maintaining a diet rich in whole grains, quality proteins, vegetables and fruits. It is also beneficial to determine the presence of toxins from sources such as clothing, cosmetics, personal care or household products and work towards their elimination.
Here are few additional hair care tips: minimize heat exposure and drying/colour-altering sunlight (best achieved with a simple fashionable hat), use natural products free of synthetic chemicals such as detergents, emollients and ammonium compounds, rinse hair properly with cold water (add a hint of lemon juice or apple cider vinegar), get a regular trim, use hair masks at least once a week and massage the scalp.
