New Research Links Causes of​ Hair Loss to​ Nutritional Deficiency
Whilst it​ may be comforting to​ know that humans are not alone in​ suffering hair loss primates such as​ monkeys also experience thinning on​ their head understanding the​ causes of​ hair loss means we can take proactive action. Even though genetics does play a​ part,​ new research has uncovered a​ nutritional deficiency link in​ both men and women. And other factors,​ such as​ stress,​ and poor hair care,​ are well within our capacity to​ change.
The genetic link in​ hair loss has been well studied. it​ is​ associated with male and female pattern hair loss,​ or​ alopecia. in​ these individuals there is​ an increased sensitivity to​ the​ sex hormone,​ DHT. DHT stands for dihydrotestosterone,​ and is​ a​ powerful metabolite of​ testosterone. it​ contributes to​ mens unique gender characteristics,​ as​ well as​ facial and body hair,​ and the​ deepening of​ mens voices at​ puberty.
DHT causes the​ growth cycle of​ hair follicles to​ shorten,​ which in​ turn reduces the​ size of​ the​ hair shaft. Increasingly narrower hair is​ grown,​ sometimes as​ fine as​ fluff,​ and in​ more extreme cases,​ there is​ complete hair loss in​ that area.
In women,​ estrogen usually counteracts the​ effects of​ testosterone. But when women go through menopause,​ or​ suffer hormonal imbalances,​ the​ reduction in​ estrogen can lead to​ female pattern baldness. Fortunately,​ this is​ not as​ drastic in​ its hair loss effects as​ male pattern baldness. Instead the​ hair tends to​ thin,​ and the​ crown parting becomes wider.
But a​ very interesting study by LOreal has linked an iron deficiency to​ hair loss,​ in​ both men and women. This was a​ placebo controlled,​ double blind study in​ which 13,​000 healthy men and women took a​ supplement,​ and had the​ ferritin iron levels in​ their blood measured and cross referenced with information on​ their hair loss.
The results showed not only a​ link between hair loss and iron deficiency,​ but they were able to​ estimate the​ risk of​ hair loss in​ a​ certain level of​ iron deficiency. For example,​ women whose blood ferritin levels dropped from a​ normal 70µg/l to​ 40µg/l,​ had a​ 28% higher chance of​ severe hair loss. the​ post menopausal women in​ the​ study who had severe hair loss all had much lower levels of​ iron than the​ women who didnt have severe hair loss.
The problem with iron supplementation,​ however,​ is​ that excess iron builds up in​ the​ bodys tissues and becomes toxic. it​ has been associated with an increased risk of​ developing chronic illnesses. Iron levels can be tested by a​ doctor,​ so if​ hair loss is​ a​ concern,​ its best to​ get your iron levels tested first before taking iron supplements.
Other potential causes of​ hair loss or​ at​ least,​ contributing factors are stress and poor hair care practices. Not brushing hair regularly,​ or​ washing it​ regularly,​ can affect the​ normal hair growth cycle.
When hair that is​ naturally at​ the​ end of​ its life cycle is​ removed through brushing,​ it​ allows another hair to​ grow underneath it. Regular brushing naturally removes dead hair that is​ ready to​ fall out. Not removing that hair means new growth cannot occur,​ as​ the​ old hair smothers the​ new growth. Dirt and oil build up can have a​ similar effect,​ so its important to​ wash hair regularly.
Stress can affect the​ circulation of​ nutrients and oxygen to​ the​ scalp,​ by causing the​ muscles in​ the​ scalp to​ tighten. if​ this happens over a​ long period of​ time,​ premature hair loss can occur. This cause of​ hair loss is​ distinct from male pattern baldness which is​ hormonal,​ but it​ can certainly exacerbate the​ condition. And stress reduction techniques are simple things that can be added to​ a​ daily routine,​ to​ prevent hair loss,​ and improve the​ overall quality of​ life.
