"Losing your hair can make you feel self-conscious but don’t worry – there are simple ways to manage and even reverse it.  Boots pharmacists can help with expert advice so you can get to the cause. An underactive thyroid, iron deficiency and hormone changes such as in the levels of androgens – which have male characteristics – can all cause hair loss. I would recommend visiting your GP for a blood test for the first two. If either is responsible, they can prescribe treatment.  If androgen production has triggered female pattern baldness, your Boots pharmacist can recommend a product to suit your needs. Products containing minoxidil increase blood flow to the scalp and help nutrients get to hair follicles. They are easy to use but can take several months to show an effect.  Some people may prefer to use products that can help hair look thicker, such as those containing hair fibres.  Eating a healthy diet including a range of fruit and vegetables is important but in addition, people who want particular support for their hair or who may feel their diet is lacking in certain nutrients may want to consider a supplement. Look for one containing biotin, zinc and selenium, three nutrients known to support normal, healthy hair growth."  "Hair loss affects eight million women in the UK. In those under 50, the most common cause is a drop in oestrogen levels about 12 weeks after giving birth (hair growth usually returns to normal after about six months). To support hair health, ensure you eat plenty of protein.  Another common reason is low levels of iron and zinc, so you may need your levels checked by your doctor, especially if you’re vegan or vegetarian. For iron, eat beef, brown lentils and dark green vegetables; for zinc, chicken, dairy and whole grains.  Polycystic ovary syndrome causes increased levels of androgens – the hormones with male characteristics – which can trigger hair loss. The oral contraceptive pill can help but you must see your GP for this. The menopause can also trigger a similar increase in these hormones, causing hair loss around the temples and at the crown. Hair loss accompanied by thinning eyebrows is a sign of thyroid issues so speak to your GP.  Another cause is alopecia areata, where hair falls out in small patches. Possible triggers include infection, a virus or a genetic link.  Lastly, intense stress can inhibit hair growth. Aim to eliminate “chronic stressors” (the type that never relent) and try a yoga class."  For advice on your hair loss ask your local Boots pharmacist or visit boots.com
