How to Prevent Hair Loss, Hair loss avoiding factors

• Hair loss has multiple causes, including diet, mineral deficiency, medications, stress, pollution, and your genetics. Up to one third of the population suffers from hair loss, and of that third, thousands are women. Whatever the cause of hair loss that might be worrying you, it's important to understand what is hair loss, how hair grows, and what you could be doing before hair loss even becomes an issue for you. In this article, you'll find out all three answers, as well as some short advice on what to do if hair loss does become an issue for you.
• Understand why hair loss happens. Hair loss (alopecia) occurs mainly on the head but it can also happen on other parts of the body. It can happen at any age and will affect an estimated 30 to 40 percent of any population. It is not always easy to identify the reason behind hair loss in an individual case but the generally known reasons behind hair loss can range from genetics and aging to diseases and stress and poor diet. Even childbirth can trigger hair loss for some women.
• Androgenetic alopecia: This is the most common form of hair loss and is also referred to as male-pattern or female-pattern baldness. Hormones and genetics seem to play the main role here. Male-pattern baldness is hereditary, from either side of the family, and can even skip generations. It tends to occur on the crown and at the temples and when these patches join together, the top of the hair is left completely bald. Statistics show that this type of hair loss affects 30 percent of men aged 30, 50 percent of men aged 50, and 70 percent of men aged 70. For women, the hair thins initially on the frontal area and the crown and moves down the sides of the head, while the back of the head remains dense with hair. This is hereditary and tends to affect women mostly after menopause.
• Toxic alopecia: This type of hair loss seems to occur following physical or emotional stress. Things such as illness, scalp infections, sudden loss of weight, surgery, drugs, and pregnancy/childbirth can cause this type of hair loss. Diseases such as lupus, diabetes, and thyroid disease can bring about such hair loss, as can chemotherapy, heart disease drugs, and radiation therapy. Hair loss that occurs as a result of a mental or physical stress can occur some 2 to 3 months after the event that sparked the stress.
• Alopecia areata: This is actually a skin disorder which causes hair on the affected skin areas to fall out. It is usually the scalp or beard and is thought to have autoimmune causes. This type of hair loss seems to be most common in young people. The hair usually grows back.
• Alopecia universalis or totalis: All body hair is lost, from everywhere, including eyebrows and eyelashes. Hair follicles are not destroyed; the inability to grow hair back is psychological and getting hair to grow back again is not easy.
• Trichotillomania: This is hair loss due to hair pulling, a habit or condition that can be corrected with treatment.
• Scarring alopecia: This is hair loss that occurs at the site of scars or damaged areas such as burns or skin cancer.
• Take care of your hair. There are no guarantees that you can prevent hair loss that is genetically programmed or hair loss caused by factors not within your control. However, you can do the best by your hair at all stages to give it the greatest chance of staying in top condition and not leaving your head sooner than it needs to. There are a number of things you can do to take good care of your hair:
• Don't subject your hair to frequent, constant heating and drying procedures. Heat weakens hair proteins, no matter the gimmicks promising softness and shine, and constant heating and drying can lead to brittleness and fragility that causes hair loss that would not have occurred otherwise. Minimize the usage of hair dryers, hot curlers, hot brushes, hair straighteners, hair fasteners, and chemical treatments and your hair will last longer. And watch where you put those heated tools; burned scalps can permanently damage hair follicles Ultimately, natural drying is best for you hair, so aim to dry it naturally more often than drying it with heat.
• Slow down on the dyeing. Never color your hair more often than 6 to 8 weeks and try for semi-coverage rather than full dyeing. When it comes to going gray, it's a lot kinder to your hair to let it turn gray than to dye it. While there are a lot of well-meaning comments about not needing to look older than you are, this ageist "beauty before health" slant overlooks the value of having your hair at all!
•  Be careful how you style your hair. Some styles that require tight pulling and elastics, clips, etc. can be a cause of hair loss if done on a daily basis. For example, tight ponytails, braiding tightly, corn-rows, and plaits, can lead to significant hair loss when done daily. Winding hair tightly onto rollers, especially heated rollers, is also liable to cause more hair loss. The medical name for loss of hair due to hairstyles that are too tight is known as "traction alopecia" and it is completely preventable as a cause in and of itself!
• Wash hair regularly with mild shampoo and be gentle with your hair. Hair washing can form a part of preventing hair loss as it can keep your hair and scalp clean (preventing the chances of infections, etc. that might cause hair loss), and provided you use a mild shampoo, clean hair will give the impression of more volume than dirty hair, which tends to sit flatter and more parted than clean hair.^[25]
• Avoid brushing wet hair. This snaps off a lot of hair that could still be growing! If you must comb wet hair, use a very wide-toothed comb. Also avoid brushing hair too frequently as doing so can injure hair and increase loss. Use your fingers to undo tangles, not a comb or brush.
• Avoid rubbing hair vigorously with a towel after washing it. This can also lead to hair breakage. Pat it dry gently instead.
• Protein-enhanced shampoos and conditioners are an eye-trick, not a hair solution. They make hair smoother and thicker temporarily because they fill in gaps on the hair shaft. However, they do not repair damaged hair, so hair that is going to fall out from poor care or other reasons, will still fall out. Shampoo does not increase hair amount either.
• When your hair is dried, use a soft-bristled brush to brush it
•  Get your stress under control. Stress damages all of your body, and your hair is no exception. Loss of hair can be one of your body's primary signals that you're overdoing things and that it's time to pull back. 
• Eat your way to top form hair. Nutritional responses to preventing hair loss are simple common sense approaches to keeping you, your hair, and your scalp healthy and are beneficial for your health all round – a healthy body is more likely to have healthy hair than an unhealthy one. It is possible that hair loss can be slowed by a healthy diet filled with vegetables and fruits. The following nutritional requirements that can be sourced adequately from a healthy diet in most cases can be of help with preventing or minimizing hair loss:
• Iron: This is an essential mineral, known as heme iron in animal food sources and non-heme iron in plant sources. Good sources of iron in your diet include: liver, beef, pork, fish, leafy greens, fortified cereal, beans, and pumpkin seeds. Vegetarian women may experience a lack of enough iron more than other people.
• Protein: Protein is essential for strong hair, but it's protein from the diet, not from a shampoo, that matters! A deficiency in protein can lead to hair loss and adequate protein can help to provide the amino acids that strengthen hair. Good sources of protein include: Seafood, white-meat poultry, milk, cheese, yogurt, eggs, beans, pork tenderloin, soy, lean beef, and protein bars.^[34] Vegans, dairy-free consumers, and others can get good non-animal protein from tempeh, tofu, wholewheat bread, peanut butter, brown rice, lentils, quinoa, nuts, seitan, beans, broccoli, potatoes, etc.
• Vitamin C: Vitamin C foods help in the good absorption of iron. Try to combine the iron source with a vitamin C source at the same time. Good sources of vitamin C include: Citrus fruit, green leafy vegetables, salad, baked potatoes, tomatoes, etc.
• Omega-3 fatty acids: These fats keep hair healthy and have a role in preventing hair from becoming dry and brittle. Good sources include: tuna, salmon, mackerel, flaxseeds, and walnuts.
• Biotin: This is a B vitamin of importance for healthy hair. Good sources of biotin include: brewer's yeast, bulgur wheat, lentils, sunflower seeds, soybeans, and walnuts.
• Zinc: Zinc is important for hair nourishment too. Good sources include: oysters, lean beef, peanut butter, turkey, and pumpkin seeds.
