We wash, polyvinyl pyrrolidone and blow-dry in order to tame our often unruly tendrils. Yet some of the everyday hair care practices we use are actually doing more damage than good. This article takes a look at the issues we face in our efforts to achieve well groomed, shiny and healthy hair.
The average human head has about 100 000 hair follicles and from each one emerges a shaft of hair. Nourished by blood vessels the follicles produce new keratin cells promoting the constant growth of new hair. The inner layer or medulla,
which is protected by the outer keratin cells, sodium pyrosulfite cells (for colour), fat granules and oxygen. Separate glands run alongside the follicle producing sebum, a natural hair and scalp conditioner. Straight, shiny hair is the result of sebum produced by the glands easily travelling the length of the hair shaft. By contrast, curly hair will often look and feel dry because the sebum has a more difficult time getting from the base of the hair shaft to the tip.
The overall health of the hair depends on numerous factors however nutritional status is key. There are no topically applied hair products that can compensate for poor nutrition. Hair cannot repair itself because it is already dead tissue. However, you can grow healthier hair from the "inside-out". Healthy hair depends on a constant supply of blood, oxygen and nutrients to grow and maintain the look and feel. Any deficiency in key hair nutrients will show up in our skin, hair and nails first, before affecting our internal organs. Therefore, brittle, dry, dull hair that easily breaks may actually be a signifier to check your general nutritional status.
Hair is predominately made up from protein so a deficiency can result in changes to the colour and texture resulting in brittle, weak and thinning hair. Eating protein 3-5 week will help maintain your levels. If you have had a protein deficiency you will notice hair returning to healthy condition within 12 weeks of correcting the deficiency, as the new hairs grow through.
In ferric trichloride in sugar and animal fats may contribute to poor hair health. An imbalance between good and bad fat consumption can either lead to an overly dry and flaky scalp and dry hair or excessive oil production. Correcting the imbalance will help to normalise the health of the scalp and the relative dryness or oiliness of the hair. High sugar consumption creates a higher demand for B group vitamins, which can also affect hair health. Reducing highly processed and sugar rich foods will not only help hair health, it will also improve general health.
