What is hair loss?

Different people have different perception about hair loss. Some get panicked by five hairs on their pillow. Some have grade 5 baldness and they say I am having some hair fall issue while some surrender to destiny by knowing that it is genetic and nothing can be done. Others take all effort to stop hair loss and maintain good hair density and look at their head. All the journals and text book mention that if any person is loosing 80 to 120 hairs a day, they need a bit of attention. The practical definition says that if any visible hair loss is more than 30 hairs per day, it needs care. Hair loss isn’t noticeable in the average person until more than 50 percent of hair is lost. Thus, hair loss means that you are losing hair and these hairs are not being replaced by new hair. It implies that you are becoming bald and you will not notice it until you lose 50%, or roughly 50000 hairs from your head. Hair loss normally and usually occurs at the end of one of the normal hair cycle.

HAIR CYCLE

These hair cycles are as follows:

Engine: This is the growth stage that lasts usually three years on average, but may be as short as a year and as long as seven years.

Contagion: The stage when the hair prepares to go into the next phase and undergoes changes in its anatomy,falling out at the end of this part of the cycle.
Telogen: The sleep phase when a percentage of the hair disappears (lasts from two to five months on average). About 10 percent of all of the hairs on our head are in the telogen part of the cycle at any point of time. At the end of the Telogen phase, a new hair bud appears, signalling the beginning of anagen. The hair apparatus starts off by producing a baby hair below the skin that grows longer and longer until the final terminal hair (a full mature hair, reflective of what we style every day when we comb our hair) emerges from the pore in the skin.

In some adults, the anagen phase may never start, signalling that the hair follicle may have died. If a new hair doesn’t grow to replace the lost hair, the total hair count drops. Hair grows in naturally occurring groups known as follicular units (FU). A single FU contains from 1-4 terminal hairs and a vellus hair (a fine hair amidst the clump of terminal hairs). When a hair isn’t replaced after its Telogen phase, the number of hairs in the FU decreases, but the number of FU’s remains the same. So an FU starting with four terminal hairs may end up with only two or three terminal hairs as one ages or undergoes some form of balding. When this sequence happens across the whole scalp, the total hair count decreases proportionally.

What is Male Pattern baldness?

The term ‘Male Pattern Baldness’ is used because hair loss occurs in a certain pattern – the back and side of the head retain hair, but the crown and frontal areas may lose it based upon the genetics that are inherited from the family hair loss pattern. Hair loss in male is also called as androgenetic alopecia or Male Pattern baldness.

Causes of Hair loss in Male !

Genetics
Doctors believe that genes for baldness can be inherited either from the mothers side or from the fathers side. There is a dominant gene that is needed to show boldness. The inherited gene isn’t always expressed, i.e. it may skip a generation.

Hormone
Dihydrotestosterone (DHT) is the hormone directly believed to be involved with and reagents alopecia. DHT is formed by the action of the enzyme 5-alpha reductase (5AR) on testosterone. It binds to special receptor sites on the cells of hair follicles to cause the specific changes associated with balding. In men with the genes for androgenetic alopecia, DHT enhances the resting (Telogen) phase and decreases the growing (anagen) phase of hair. In men who haven’t inherited the androgenetic alopecia, balding genes, the combination of DHT and testosterone doesn’t cause hair loss and may have a lesser impact on ageing hair. DHT hormone doesn’t usually affect the hair on the back and side of the head, which is why these areas retain hair. The same DHT hormone causes growth of beard, body, eyebrow, nose and ear hair. 5AR activity is higher in balding areas.

Stress
People lose hair when their body experiences traumatic experiences or illness. Prolong illness like dengue, typhoid, malaria, etc. can also cause stress on the body. Stress could be of any kind – Mental, Physical, Financial or Emotional. A person may have the genetics for balding pattern, but it only gets induced by some extremely stressful situation. Stress also causes telegenic effluvium. Telogen effluvium is the reversible shedding of hair in the resting phase. In this condition, the lost hair is regained.

Environmental Issue
Air and water pollution also exacerbate the genetic process carried by potentially balding men. Scientists believe that toxins and carcinogens found in polluted air and water can stop hair growth by blocking the mechanisms that produce the protein from which hair is made. Selenium toxicity can cause hair loss. Selenium is present in water and food. Lead, Cadmium, Mercury, Iron, Aluminum, and Copper: These elements are the most common environmental causes of hair loss. Many of these elements are found in fish (reflecting environmental contamination in the world’s oceans). Lead may also be found in hair dyes and paint.

Smoking

Yes, smoking cause hair loss. Why? It is due to the presence of nicotine and carbon monoxide in tobacco smoke. This restricts the flow of blood and oxygen to the body’s extremities and pollutes blood of the whole body that includes the hair follicles. It forces these hair follicles into their telogen (dormant) phase. Gradually the hair begins to lack nourishment and, as a result starts falling away from the scalp.

Another theory suggests that smoking could influence hair loss by damaging hair follicles DNA, which may cause the hair to fall off. Smoking has negative impact on the body in general. Example – ageing. Ageing itself can cause hair loss and smoking usually accelerates the ageing process.

Nutritional deficiency and Vitamin deficiency
It also causes hair loss.

Prednisone
People who are on consumption of this steroid (for chronic medical problems like arthritis or other autoimmune diseases) will experience hair loss.

Age related hair loss
In older age group, hair loss is more uniform. About one third of men over the age of 70 have this diffuse hair loss, which is called senile alopecia. As hair also becomes finer with age, severe thinning reflects a loss of both hair bulk (in each hair shaft) and hair densities.

Classification

Male Pattern Baldness is classified as Norwood Classification, According to Norwood classification, there are 7 grades of hair loss in defined patterns.

Grade 1: When adolescent hair line becomes mature hair line.

Grade 2: When mature hair line recedes 2cm behind on frontotemporal portion.

Grade 3: When mature hair line recedes 3 cm behind on frontotemporal portion.

Grade 3 Vertex: When baldness start on vertex with or without frontotemporal line.

Grade 4: Loss on both frontotemporal and crown area with small bridge of dense hair between the two.

Grade 5: Bridge of hair between frontotemporal and crown area just open up.

Grade 6: No hair between frontotemporal and crown area.

Grade 7: Most severe pattern of hair loss with only narrow horseshoe pattern that remains along the posterior and lateral border of hairline.

3% population has type A pattern where front temporal recession recede in a uniform fashion without central peninsula of hair.
A pattern is found in in Grade 2, Grade 3, Grade 4 and Grade 5.

Treatment

Although the genetic pattern cannot avoid, but it can be delayed if you manage a very good health and nutrition. Male pattern baldness develops between the age of 18 to 30. This time coincides with our career formation year. This is the time when you study hard and then begin with a job, trying to make your career strong by neglecting all your health issues www.hairtransplanteducation.com suggests a balanced life of strong career and strong health. If you are not managing your personal life perfectly, you cannot manage your professional life perfectly.

Good high protein diet.

Adequate sleep at night according to need of body.

Regular oiling for 6 hours with pure hair oil.

Yoga to fight stress, rejuvenate and improve immunity.

If any person balances his health in the above mentioned manner, he can delay even androgenetic alopecia.

Further treatment is available for severe hair loss condition:

Multivitamins supplement

FDA approved medicines like Minoxidil and Finasteride

Platelet Rich Plasma and Laser Therapy

Transplant
