Top 7 Reasons Why Do You Lose Your Hair

Human Hair
Most common interest in hair is focused on hair growth, hair types and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin.  Attitudes towards different hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, sex, or religion.

Top 7 Reasons Why Do You Lose Your Hair

1) Pattern hair loss, known as male-pattern hair loss (MPHL) when it affects males and female-pattern hair loss (FPHL) when it affects females, is hair loss that primarily affects the top and front of the scalp., In males the hair loss often presents as a receding hairline while in females it typically presents as a thinning of the hair.  Male pattern hair loss is believed to be due to a combination of genetics and the male hormone dihydrotestosterone.

2) Psychological distress: Mental distress (or psychological distress) is a term used, both by some mental health practitioners and users of mental health services, to describe a range of symptoms and experiences of a person's internal life that are commonly held to be troubling, confusing or out of the ordinary.  Mental distress has a wider scope than the related term mental illness.  Mental illness refers to a specific set of medically defined conditions.  A person in mental distress may exhibit some of the symptoms described in psychiatry, such as: anxiety, confused emotions, hallucination, rage, depression and so on without actually being 'ill' in a medical sense.  Life situations such as: bereavement, stress, lack of sleep, use of drugs or alcohol, assault, abuse or accident can induce mental distress.  This may be something which resolves without further medical intervention, though people who endure such symptoms longer term are more likely to be diagnosed with mental illness.  This definition is not without controversy as some mental health practitioners would use the terms mental distress and mental illness interchangeably.  Some users of mental health services prefer the term mental distress in describing their experience as they feel it better captures that sense of the unique and personal nature of their experience, while also making it easier to relate to, since everyone experiences distress at different times.  The term also fits better with the social model of disability.

3) Genetic: Genetics is the study of genes, genetic variation, and heredity in living organisms.  It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.  The father of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar.  Mendel studied trait inheritance, patterns in the way traits are handed down from parents to offspring.  He observed that organisms (pea plants) inherit traits by way of discrete units of inheritance.  This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.  Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded beyond inheritance to studying the function and behavior of genes.  Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g.  dominance ), and within the context of a population.  Genetics has given rise to a number of subfields, including epigenetics and population genetics.  Organisms studied within the broad field span the domain of life, including bacteria, plants, animals, and humans.  Genetic processes work in combination with an organism's environment and experiences to influence development and behavior, often referred to as nature versus nurture.  The intracellular or extracellular environment of a cell or organism may switch gene transcription on or off.  A classic example is two seeds of genetically identical corn, one placed in a temperate climate and one in an arid climate.  While the average height of the two corn stalks may be genetically determined to be equal, the one in the arid climate only grows to half the height of the one in the temperate climate due to lack of water and nutrients in its environment.

Pregnancy may be confirmed with a pregnancy test.  Term pregnancy is 37 to 41 weeks, with early term being 37 and 38 weeks, full term 39 and 40 weeks, and late term 41 weeks.  Among unintended pregnancies in the United States, 60% of the women used birth control to some extent during the month pregnancy occurred.

5) Chemotherapy: Chemotherapy (often abbreviated to chemo and sometimes CTX or CTx) is a category of cancer treatment that uses one or more anti-cancer drugs (chemotherapeutic agents) as part of a standardized chemotherapy regimen.  Chemotherapy may be given with a curative intent (which almost always involves combinations of drugs), or it may aim to prolong life or to reduce symptoms (palliative chemotherapy).  Chemotherapy is one of the major categories of the medical discipline specifically devoted to pharmacotherapy for cancer, which is called medical oncology.  By common usage, the term chemotherapy has come to connote the use of rather non-specific intracellular poisons, especially related to inhibiting the process of cell division known as mitosis, and generally excludes agents that more selectively block extracellular growth signals (i.e.  blockers of signal transduction ).  To avoid these connotations, recently developed therapies (against specific molecular or genetic targets) which inhibit growth-promoting signals coming from classic endocrine hormones (primarily estrogens for breast cancer and androgens for prostate cancer) are called hormonal therapies, while the inhibition of other growth-promoting influences (especially those associated with receptor tyrosine kinases) is known as targeted therapy.  Importantly, the use of drugs (whether chemotherapy, hormonal therapy or targeted therapy) constitutes systemic therapy for cancer in that they are introduced into the bloodstream and are therefore in principle able to address cancer at any anatomic location in the body.  Systemic therapy is often used in conjunction with other modalities that constitute local therapy (i.e.  treatments whose efficacy is confined to the anatomic area where they are applied) for cancer such as radiation therapy, surgery or hyperthermia therapy.  Traditional chemotherapeutic agents are cytotoxic by means of interfering with cell division (mitosis) but cancer cells vary widely in their susceptibility to these agents.  To a large extent, chemotherapy can be thought of as a way to damage or stress cells, which may then lead to cell death if apoptosis is initiated.  Many of the side effects of chemotherapy can be traced to damage to normal cells that divide rapidly and are thus sensitive to anti-mitotic drugs: cells in the bone marrow, digestive tract and hair follicles.  This results in the most common side-effects of chemotherapy: myelosuppression (decreased production of blood cells, hence also immunosuppression ), mucositis (inflammation of the lining of the digestive tract), and alopecia (hair loss).  Because of the effect on immune cells (especially lymphocytes), chemotherapy drugs often find use in a host of diseases that result from harmful overactivity of the immune system against self (so-called autoimmunity ).  These include rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, vasculitis and many others.

6) Fungal Infections: Tinea capitis (also known as herpes tonsurans, ringworm of the hair, ringworm of the scalp, scalp ringworm, and tinea tonsurans) is a cutaneous fungal infection (dermatophytosis) of the scalp.  The disease is primarily caused by dermatophytes in the Trichophyton and Microsporum genera that invade the hair shaft.  The clinical presentation is typically single or multiple patches of hair loss, sometimes with a 'black dot' pattern (often with broken-off hairs), that may be accompanied by inflammation, scaling, pustules, and itching.

7) Other causes of Hair Loss:
High Blood pressure (BP )
heart disease
hormone replacement therapy
anabolic steroids
birth control pills

Treatment For Hair Loss
1) Minoxidil is an antihypertensive vasodilator medication and is used to treat hair loss.  It is available as a generic medication and over the counter for the treatment of androgenic alopecia, a form of hair loss, in men and women.  Regaine

2) Finasteride, sold under the brand names Proscar and Propecia among others, is a medication used for the treatment of benign prostatic hyperplasia (enlarged prostate) and male pattern hair loss.  It is a type II and types III 5α-reductase inhibitor; 5α-reductase, an enzyme, converts testosterone to dihydrotestosterone (DHT).

3) Dutasteride, sold under the brand name Avodart among others, is a medication used to treat benign prostatic hyperplasia (enlarged prostate) and androgenetic alopecia (pattern hair loss).  It was developed by GlaxoSmithKline and is a 5α-reductase inhibitor which prevents the conversion of the androgen sex hormone testosterone into the more potent dihydrotestosterone (DHT).  The drug has been licensed for the treatment of androgenetic alopecia in South Korea since 2009 and in Japan since 2015 but has not been approved for this specific indication in the United States, though it is commonly used off-label. 

4) Hair transplantation is a surgical technique that moves hair follicles from a part of the body called the 'donor site' to a bald or balding part of the body known as the 'recipient site'.  It is primarily used to treat male pattern baldness.  In this minimally invasive procedure, grafts containing hair follicles that are genetically resistant to balding, (like the back of the head) are transplanted to the bald scalp.  Hair transplantation can also be used to restore eyelashes, eyebrows, beard hair, chest hair, pubic hair and to fill in scars caused by accidents or surgery such as face-lifts and previous hair transplants.  Hair transplantation differs from skin grafting in that grafts contain almost all of the epidermis and dermis surrounding the hair follicle, and many tiny grafts are transplanted rather than a single strip of skin.  Since hair naturally grows in groupings of 1 to 4 hairs, current techniques harvest and transplant hair follicular units in their natural groupings.  Thus modern hair transplantation can achieve a natural appearance by mimicking original hair orientation.  This hair transplant procedure is called follicular unit transplantation (FUT).  Donor hair can be harvested in two different ways: strip harvesting, and follicular unit extraction (FUE).
