The structure of hair is like the scales on the skin of a fish that has overlapping scales around a central core called the cortical. " Smoother the overlapping" more shiny and smoother the hair looks. This also leads to easy combing while a tangled or roughed-up structure makes the hair look rough and dull.
Diet and lifestyle are two major factors that influence the health of the hair. Poor diet, illness and deficiencies of any particular vitamin and mineral affects the quality of hair and problems like dandruff, thinning hair, balding, premature graying etc. spoil the hair.
Regularly cleaning and brushing the hair is very important. When the hairs are brushed, oil-producing glands in the scalp get stimulated. This natural oil makes the hair glossy and healthy. To give extra shine to the hair, after washing rinse the hair with some lemon juice mixed in a cup of warm water.
