Lifestyle Choices

The type, the length of growth, thickness, thinness, straightness, and curl of your hair depend on your inheritance, but the condition of your hair depends on the internal state of your body, which feeds the papillae that produce it. For hair to be beautiful, the cuticle and the cortex have to be strong. It has always amused me when I hear hairdressers arguing about whether or not diet has anything to do with the beauty of hair, because it does, as any farmer knows well. Not only can you change the look of an animal’s hair by altering its diet (and that goes for the human animal too), you can also tell a great deal about its internal condition by examining its hair. If you have a sheep that is poorly, its coat shows it. Horses, dogs, and cats are given special vitamin and mineral supplements to improve their coats for shows. But only recently has this aspect of hair care even begun to be looked at for human beings. (more…)

The shine of your hair depends on the condition of the cuticle. Made up of transparent keratin, the cells of your hair’s cuticle should form a clear, flat surface that refracts light, making your hair look shiny. But in order for these fish-scale-like plates to lie flat, the cuticle has to be healthy and contracted. This means that the imbrications—the natural shingles of the cuticle—need to be closed. When they are closed, your hair is protected from much physical and chemical damage and light catches it beautifully. Many things can disrupt the cuticle and lead to the opening of the imbrications: very alkaline shampoos, for instance, which make the hair shaft swell. The swelling pushes out the scaly cells, making them stand away from the shaft. Very strong alkaline substances such as permanent wave solutions and bleaching agents can even dissolve some of the cuticle, leaving holes and tears in it, which makes your hair look permanently dull.
