  2. Stress
  3. Dry scalp
  4. Hair styling
  5. Tying hair tight
  6. Brushing wet hair
  7. Hormonal imbalance
  8. Lack of iron
  1. Lack of Protein

    Lack of Protein

    Lack of protein in routine diet could cause deficiency of certain essential protein and vitamins such as vitamin B and C, which are very essential for healthy growth of hair. Due to lack of protein, roots lose the strength to hold hair and hair follicles too becomes weak and starts shedding out very quickly.

  2. Stress


    Mental or physical stress could trigger hair loss problem suddenly. Stress can trigger the shedding out phase of hair called telogen prematurely and could even more hair into shedding phase. Mental or emotional stress such as any shock or incident, work pressure or any family issue could increase the rate of hair fall eventually.

  3. Dry scalp

    Dry scalp

    Health of scalp plays a vital role in the problem of hair loss. If scalp is sensitive and prone to several infections, then chances of hair loss becomes higher. Unhealthy or unhygienic scalp condition also leads to bacterial and fungal infection and problems such as dandruff, which contribute to hair loss.

  4. Hair styling

    Hair styling

    Excessive hair styling leads to thinning of hair and makes them weaker gradually. Exposure of hair to excessive heat causes hair breakage and consequent hair fall. Hair colouring is one styling method which involves lots of harsh chemical and damage hair permanently

  5. Tying hair tight

    Tying hair tight

    Did you know keeping your hair tied in a pony tightly can make you go bald or increase instance of hair fall? It is indeed true.

    All of us love to keep our hair perfectly in place. Thus, we often tie them too tightly, which in-turn can result into hair-loss and hurt our scalp. Tying your hair in a bun or pony requires you to pull every single hair on the scalp. The pressure that is often applied while doing this can result in breakage of the tips or roots of the hair and make them ultimately fall. Even while untying your hair, you might have often noticed hair strands that get entangled with the rubber band. This is because the pulling and tight binding leads to weaker roots. Also, pulling can eventually become a reason for you suffering from alopecia, which is another form of hair loss.

    If you love tying your hair, make sure it is not tied up tightly and stay away from plastic or rubber made bands. Use a soft band made of cloth as it puts less stress on the hair and helps in reducing chances of other hair problems like split ends and hair breakage.

  6. Brushing wet hair

    Brushing wet hair

    Rigorous towel drying or combing can ruffle the cuticles and brushing it can cause breakage and eventual hair fall.  Also brushing your hair while they are wet can be problematic. Hair are at their vulnerable best when wet. Any amount of pressure or stress applied on them can lead them to break and fall. One should avoid combing their hair when they are dripping with water. Using a wide tooth comb for brushing is recommended as there are less chances of hair getting entangled and breaking. Brush your hair gently or with a soft hand to avoid them from getting pulled from the root and falling off.

  7. Hormonal imbalance

    Hormonal imbalance

    Hormonal changes due to pregnancy or menstrual period often leads to hormonal changes and this triggers the problem of hair loss. Often, thyroid gland affects the hormone levels and causes the problem of hair loss. Childbirth and birth control pills also lead to hormonal imbalance and increases hair fall rate suddenly.

  8. Lack of iron

    Lack of iron

    Lack of iron due to lack of iron-rich food in diet could lead to deficiency of iron in body. Iron deficiency in blood is called anaemia in medical terms, which is considered a major reason, triggering hair loss problem.

    While we all love long to have long and wavy hair, there is some amount of science that goes behind achieving them. If your hair is thinning, it is imperative to understand the hair growth cycle as it enables you to learn more about the quality and kind of hair you have and if in case you suffer from any hair problem, it can help you get to the root of it.

Hair growth cycle:

Hair Growth Cycle: Anagen, Catagen, Telogen

The hair growth cycle primarily consists of three major stages:

  1. Anagen phase: On an average basis, hair grows to about half inch in a month. They are also known to grow faster during the summer season than in winters. The first stage of hair growth, the anagen phase, lasts, on an average, to about 3-5 years meaning your hair can grow upto 18 to 30 inches during this phase. In this stage, a bulb forms at the bottom of the hair follicle that later matures into a full-length hair strand and eventually grows past the scalp barrier.

  2. Catagen stage: Catagen stage is the second stage of the hair growth cycle and is also known as the transition phase that occurs at the end of the anagen phase. It is during this phase of hair growth that few structural changes take place over a period of few weeks. Unlike the anagen stage, the bulb at the bottom of the follicle detaches itself from the blood supply and starts to move upwards. Because the hair follicle starts to shrink, it loosely grasps the hair shaft which leads to shedding of the hair easily. This stage usually lasts upto 10 days.

  3. Telogen stage: This is the last phase of the hair growth cycle and is also known as the resting stage where the hair is released and they tend to fall out. In this stage, the follicle remains dormant or inactive for a period of about 3 months before the entire cycles kicks up again and restart on the hair growth. But one must know that each hair follicle is independent and goes through the growth cycle at different times. Otherwise all your hair must have fallen out in one go. Therefore, on a healthy head, about 80-90 strands of hair each day.

Hair are often called the barometer of your health and losing them can be quite a traumatic experience. Seeing your hair on the pillow, on the ground post shower or while combing can raise alarm bells among people. While losing about 90-100 hair strands on a daily basis is considered normal, anything more than that could be a sign of something serious and must not be ignored at any cost. While on an average, men may experience hair loss more than women, the fact is that it can be demoralizing for both.

Chronic Hair Fall Reasons:

The reasons of excessive hair loss are often attributed to a number of reasons. Some of them are as listed below:

  1. Genetic: Hereditary or genetic disorders are thought to be primary reasons for hair loss. Both men and women get affected by them and can also lead to complete baldness among both. In men, genetic disorders can cause what is also known as ‘male pattern baldness’ which results in receding hairline on the forehead and further reaching to the back of the head/scalp. Among women, the female pattern baldness results in thinning of the hair over the crown or top of the head. This problem is more common among men than in women and early detection and treatment can stop the hair from falling further.


  2. Illness: An underlying medical condition or illness could be the reason behind you losing hair in excess. While many people do not get to know about it as they attribute hair loss to something common or normal. The most common kind of hair loss that occurs while you are ill is known as telogen effluvium. The hair growth cycle is based on balance and equilibrium of hormones and any kind of disturbance to this balance can cause your hair to fall. When you are sick or suffer from some kind of illness, that balance of the hair growth cycle is shaken or disturbed. Hence, hair loss or excessive hair fall.


  3. Poor diet: Just like our rest of the body requires all the essential nutrients and vitamins to function properly our hair need a good nourishing diet to grow thick and healthy. Eating too much of junk, oily or sugar laden food can prove fatal for your hair health. A poor, insufficient or imbalanced diet can drastically effect the health of the scalp and hair, make the hair follicles weak and result in them falling. A nutritious diet can not only add vitality and natural shine to the hair but also make them strong from root to tip. If you are on some kind of a diet, make sure to add protein, vitamin and iron rich products as they can add health to the hair and make them look naturally beautiful.

  4. Medication: Certain kinds of medicines can lead for your hair to fall. More common among these medicines are the one that aid in blood thinning, antidepressants, and blood pressure drugs. Even if you are taking medicines for some kind skin related condition or rheumatic condition or a nonsteroidal anti-inflammatory medicine like ibuprofen, chances are you might experience hair loss. Lowering the dose or switching to another medicine can help curb the problem. But speak with your doctor first.


  5. Excessive use of chemicals: You might love trying different hair creams, shampoos, hair colour and lotion but beware as they may affect the health of your hair in the long run. The chemicals present in hair products can lead to scalp infections, dandruff, itchy & oily scalp, inflammation and hair breakage. All of which ultimately leads for your hair to fall. Once in a while using OTC products is fine but their regular use can affect the hair follicles and cause irritation to the scalp. If you want, try and opt for herbal or natural hair products as they cause less or almost no damage to the hair.

    Excessive use of chemicals

  6. Pollution: Hair exposed to external factors like polluted air and environment can cause damage to the hair and lead them to fall. Pollution is the main reason for scalp infections like dandruff, oiliness, eczema, itchy scalp and bad texture of hair that makes them rough, dull and break into split ends. Stepping out in wet hair attracts pollutants and irritants to the scalp and if they are not cleansed properly they stay back and harm the skin on the scalp. An infected scalp is the major cause for your hair to become brittle and fall.


  7. Sun damage: While vitamin D is good for your scalp and hair health, over exposure to the sun cause can lead your hair follicles to get damaged due to excessive heat. The heat of the sun causes the hair to become dull, brittle, split at the end and eventually fall. Its harmful UV rays even robs the hair of their natural colour and shine and also make them look rough and frizzy. To avoid your hair from falling due to sun, always cover your hair with a scarf before stepping out in the sun and apply serums that will protect your hair from the sun’s UV rays.

  8. Alopecia areata: It is a kind of hair loss symptom that occurs when the immune system attacks the hair follicles. It usually starts with leaving small bald patches scattered on the scalp and as the time progresses it leads to complete baldness or hair loss. This problem usually starts at an early age and for a person suffering from it, the hair may often grow in patches in some area but may fall out in the other.

    Alopecia areata

  9. Vitamin deficiency: Vitamin deficiency and thinning of hair go hand-in-hand. Lack of biotin, a kind of vitamin B, or vitamin D can cause the hair to fall. On an average, doctors recommend 15 to 30 grams of vitamins in your daily diet for a healthy body and hair. Including foods like fish, egg, milk, nuts, legumes, soybeans, butter and whole grains can suffice your need for vitamins and turn keep your hair thick and healthy.

    Vitamin deficiency

  10. Pregnancy: Hair loss that is related to pregnancy usually occurs post-delivery. During pregnancy, the hair goes into a resting phase which is also a part of the normal hair loss cycle. It is not a very serious condition and does not lead to baldness or patchiness on the scalp. The hair usually tends to stop falling within 3-4 months and goes back to their normal growth and fall cycle. But if the condition persists for a longer duration, it is recommended to see a doctor and know the underlying reason for the hair fall.


  11. Dramatic weight loss: Crash or fad diets can be one of the major reasons for your hair to fall excessively! When you go out on a diet, you often tend to cut out on natural sources of protein, vitamins or minerals from your diet fearing weight gain or failure of the diet plan. This can lead to stress on the body and thinning of hair. Sudden weight loss is seen as a form of physical trauma and any kind of stress can affect the health of your scalp and hair. If not treated in time, it can lead for your hair to fall excessively and also lead to other forms of eating disorders like bulimia or anorexia.

    Dramatic weight loss

In the end, remember to avoid or go slow on using styling products and tools and let your hair stay as natural and beautiful as possible.
