Dealing with Dandruff 0

Dandruff is a common chronic scalp condition marked by flaking of the skin on your scalp. Although dandruff isn’t contagious and is rarely serious, it can be embarrassing and sometimes difficult to treat.

The good news is that dandruff usually can be controlled. Mild cases of dandruff may need nothing more than daily shampooing with a gentle cleanser. More stubborn cases of dandruff often respond to medicated shampoos.

Symptoms

For most teens and adults, dandruff symptoms are easy to spot: white, oily looking flakes of dead skin that dot your hair and shoulders, and a possibly itchy, scaly scalp. The condition may worsen during the fall and winter when indoor heating can contribute to dry skin, and improve during the summer.

A type of dandruff called cradle cap can affect babies. This disorder, which causes a scaly, crusty scalp, is most common in newborns, but it can occur anytime during infancy. Although it can be alarming for parents, cradle cap isn’t dangerous and usually clears up on its own by the time a baby is 3 years old.

When to see a doctor

Most cases of dandruff don’t require a doctor’s care. But if you’re still scratching your head after several weeks of experimenting with over-the-counter (OTC) dandruff shampoos, or if your scalp becomes red or swollen, see your doctor or dermatologist. You may have seborrheic dermatitis or another condition that resembles dandruff. Often your doctor can diagnose the problem simply by looking at your hair and scalp.

Causes

Dandruff can have several causes, including:

  • Dry skin. Simple dry skin is the most common cause of dandruff. Flakes from dry skin are generally smaller and less oily than those from other causes of dandruff, and you’ll likely have symptoms and signs of dry skin on other parts of the body, such as your legs and arms.
  • Irritated, oily skin (seborrheic dermatitis). This condition, one of the most frequent causes of dandruff, is marked by red, greasy skin covered with flaky white or yellow scales. Seborrheic dermatitis may affect your scalp and other areas rich in oil glands, such as your eyebrows, the sides of your nose and the backs of your ears, your breastbone, your groin area, and sometimes your armpits.
  • Not shampooing often enough. If you don’t regularly wash your hair, oils and skin cells from your scalp can build up, causing dandruff.
  • Other skin conditions. People with skin conditions such as eczema — a chronic, inflammatory skin condition — or psoriasis — a skin condition marked by a rapid buildup of rough, dry, dead skin cells that form thick scales — may appear to have dandruff.
  • A yeast-like fungus (malassezia). Malassezia lives on the scalps of most adults, but for some, it irritates the scalp. This can irritate your scalp and cause more skin cells to grow. The extra skin cells die and fall off, making them appear white and flaky in your hair or on your clothes. Why malassezia irritates some scalps isn’t known.
  • Sensitivity to hair care products (contact dermatitis).Sometimes sensitivities to certain ingredients in hair care products or hair dyes, especially paraphenylenediamine, can cause a red, itchy, scaly scalp. Shampooing too often or using too many styling products also may irritate your scalp, causing dandruff.

Risk factors

Almost anyone can have dandruff, but certain factors can make you more susceptible:

  • Age. Dandruff usually begins in young adulthood and continues through middle age. That doesn’t mean older adults don’t get dandruff. For some people, the problem can be lifelong.
  • Being male. Because more men have dandruff, some researchers think male hormones may play a role. Men also have larger oil-producing glands on their scalps, which can contribute to dandruff.
  • Oily hair and scalp. Malassezia feeds on oils in your scalp. For that reason, having excessively oily skin and hair makes you more prone to dandruff.
  • Poor diet. If your diet lacks foods high in zinc, B vitamins or certain types of fats, you may be more likely to have dandruff.
  • Certain illnesses. For reasons that aren’t clear, adults with neurological diseases, such as Parkinson’s disease, are more likely to develop seborrheic dermatitis and dandruff. So are people with HIV infection and those recovering from stressful conditions, particularly heart attack and stroke, and those with compromised immune systems.

Preparing for your appointment

You don’t need any special preparations for an appointment to diagnose dandruff. Your doctor should be able to diagnose your dandruff and its cause simply by looking at your scalp and skin. If you’ve started using any new hair care products, bring the bottles with you to your appointment or be prepared to tell your doctor about them, so he or she can determine whether the products may be causing your dandruff.

Radio drama improves people’s attitude to health 0

A radio drama project to promote child nutrition, agriculture and maternal/child health issues has shown an improved attitude of listeners to such issues.

According to the project implemented for six months at Saboba and Savelugu Assemblies in the Northern Region in 2018, those, who listened to the radio dramas on child nutrition, agriculture and maternal/child health issues, improved in terms of their attitude towards those issues compared to those, who did not listen.

The project, whose findings were released at a workshop in Tamale on Friday, used radio dramas to propagate messages on good nutrition, health and agricultural practices to listeners to assess if listening to such messages would have any impact on their lives.

It was implemented by the Texas A&M University School of Public Health in the United States, University for Development Studies (UDS), Ghana Health Service (GHS), Ministry of Food and Agriculture, and Community Health Nurses Training College, Tamale.

Dr Mahama Saaka, Senior Lecturer, Department of Nutritional Sciences of UDS, who presented the findings at a forum in Tamale, said even though the attitude of listeners improved, it did not result in a change in their health conditions as malnutrition was still high at the area.

Dr Saaka suggested that Ghana Health Service scale up the project to reach a large number of the population to help change their attitudes to help improve the country’s health indicators.

Professor Lisako McKyer, Associate Dean for Climate and Diversity, Health Promotion and Community Health Science at Texas A&M University was hopeful that the project marked the beginning of a productive partnership amongst the implementers saying “Together, we can and we will positively impact the lives of all.”

Hajia Azara Amadu, Northern Regional Nutrition Officer lauded the project saying it was in line with the behavioural change campaigns of the GHS to promote improved health practices amongst the people.

Adverse Health Effects of Plastics 0

In addition to creating safety problems during production, many chemical additives that give plastic products desirable performance properties also have negative environmental and human health effects. These effects include

  • Direct toxicity, as in the cases of lead, cadmium, and mercury
  • Carcinogens, as in the case of diethylhexyl phthalate (DEHP)
  • Endocrine disruption, which can lead to cancers, birth defects, immune system suppression and developmental problems in

Chemical Migration from Plastic Packaging into Contents

People are exposed to these chemicals not only during manufacturing, but also by using plastic packages, because some chemicals migrate from the plastic packaging to the foods they contain. Examples of plastics contaminating food have been reported with most plastic types, including Styrene from polystyrene, plasticizers from PVC, antioxidants from polyethylene, and Acetaldehyde from PET.

Among the factors controlling migration are the chemical structure of the migrants and the nature of the packaged food. In studies cited in Food Additives and Contaminants, LDPE, HDPE, and polypropylene bottles released measurable levels of BHT, Chimassorb 81, Irganox PS 800, Irganix 1076, and Irganox 1010 into their contents of vegetable oil and ethanol. Evidence was also found that acetaldehyde migrated out of PET and into water.

Recommendations

Find alternatives to plastic products whenever possible. Some specific suggestions:

  • Buy food in glass or metal containers; avoid polycarbonate drinking bottles with Bisphenol A
  • Avoid heating food in plastic containers, or storing fatty foods in plastic containers or plastic wrap.
  • Do not give young children plastic teethers or toys
  • Use natural fiber clothing, bedding and furniture
  • Avoid all PVC and Styrene products
