8 Things Your Hair Is Desperately Trying To Tell You About Your Health
1. Iron Deficiency An iron deficiency doesn’t just cause fatigue and dizziness – it’s also closely linked to hair loss, according to a review of 40 years of research. When iron deficiency progresses into anemia, it sends the body into survival mode, channeling oxygen to support vital functions instead of using it to keep the hair on your head! Those suffering hair loss due to iron deficiency will be pleased to know that treatment for hair loss is enhanced when iron deficiency is addressed. Wondering if you’re deficient in iron? Here are 18 warning signs you should be looking out for.
2. A Lack of Other Vitamins and Minerals A lack of many other nutrients in the diet can lead to an unhealthy mane. Again, this is because hair is a non-essential tissue so more important organs and tissues get their pick of the nutrients first, before the leftovers get to the hair. If you have less than ideal levels of many vitamins and minerals, it may show on your hair. Low levels of Vitamin C can lead to dry and lackluster locks, while premature graying suggests that you might have suboptimal levels of Vitamin B12 and folic acid. But any vitamin deficiency can cause hair loss. Vitamins A, B, C, D and E are all important to help keep your hair in good shape, as are trace minerals such as selenium, copper, zinc and magnesium. Eat a well-balanced diet and you should meet all your nutrient needs. High-quality supplements can also be used if you feel you need a boost. One thing to note is that you may not see the result of a poor diet until the end of a typical three-year hair growth cycle, although you can be sure that it is causing damage. So even when you improve your diet be patient, your hair will thank you for it in the long run.
3. Not Enough Good Fats While many people shy away from fatty foods, sources of polyunsaturated and monounsaturated fatty acids are vital for healthy hair and skin as well as for overall vitality and longevity. A dry and flaky scalp or splitting hairs can often signal a lack of these good dietary fats – which work to lock moisture into the skin and hair cells, keeping them supple and youthful. Dietary fats also help your body absorb the key fat-soluble vitamins (A, D, E and K) which are important for hair health. For shiny, nourished locks make sure to eat sources of essential fats daily – like oily fish, avocados, olive oil, nuts and seeds.
4. Lack of Protein Hair is made up of a protein called keratin, which means that adequate dietary protein is needed to encourage hair grow. Hair that won’t grow, or that is brittle and breaks easily, could be down to a lack of high-quality protein. You may also notice that you have shorter layers on the top of your head, caused by the breaking of new hairs which aren’t strong enough to withstand heat and chemical treatments. Aim to eat protein at every meal. Good sources include beans, lentils, fish, organic grass-fed meat, eggs from pasture-fed hens, and nuts and seeds.
5. Dehydration Given that our body consists of around 60 to 65% water, it’s hardly surprising to learn that dehydration can cause us to look and feel less than our best. Very weak and damaged hair or excessive shedding can be a sign that you need to incorporate more water into your daily regimen. While herbal teas and coconut water all count towards your water intake, limit the amount of alcohol and caffeine you imbibe as these can act as a diuretic and cause you to lose water. Exactly how much water do you need? Now that the old ‘8 glasses of water a day’ rule is believed to be without any scientific basis, there’s a much easier way to measure your hydration levels – check the color of your urine. A light straw color is what you’re aiming for.
6. Polycystic Ovary Syndrome (PCOS) Polycystic ovary syndrome (PCOS) affects between 1 in 10 and 1 in 20 women of childbearing age. Women with PCOS have an hormonal imbalance which leads to issues like ovarian cysts, acne, weight gain, irregular menstrual periods and – in terms of hair – an increase in growth on the face and body (hirsutism) and thinning or receding hair on the head. If these symptoms sound familiar, consult your doctor for further testing.
7. Thyroid Issues An underactive thyroid, also known as hypothyroidism, is a condition where the thyroid gland doesn’t produce enough hormones, causing the metabolism to slow. Hypothyroidism leads to sudden weight gain, fatigue and feeling cold. This condition can also affect the hair by causing it to become extremely brittle or to fall out, with even a mild change in the thyroid hormones causing a noticeable difference. Limp, fine and dry hair can also indicate your thyroid is operating at suboptimal levels. While you may feel your hair is thinning due to hair loss, it can actually be due to a change in the hair’s texture – where the individual strands become fine and weak. A simple blood test can determine if you’re suffering from hypothyroidism.
8. Pregnancy or Menopause If you notice changes in your hair that can’t be explained by other causes, consider if you could be pregnant or going through menopause. Pregnancy brings a great deal of hormonal changes to a woman’s body. High estrogen levels cause greater hair growth – leading to thicker hair; but they can also slow down the loss of old, worn out hairs, leading to frizzy or out of control locks. Expectant mothers may also find that their oil-producing glands either speed up or slow down production, causing normally straight hair to become wavy or previously dry hair to become oily. Thankfully, these changes are only temporary and will subside after birth. Menopause almost always affects the hair with estrogen again at play – this time levels fall, while the levels of male hormones increase. This variation in hormones can lead to thinning strands of hair – giving an overall appearance of hair loss – or a recession at the frontal hairline and temples (similar to the early stages of male pattern balding). Excess facial and body hair can also result.
