Common Hair Loss Causes



Common hair loss causes
One of​ the​ most worrying aspects of​ hair loss treatment is​ the​ tendency of​ so many people to​ seek solutions without first determining what has caused their loss in​ the​ first place.
At best,​ sufferers may waste money on​ inappropriate wonder cures or​ even legitimate treatments that unfortunately are not suitable for​ their particular needs. at​ worst,​ some people may be risking their health by selfprescribing powerful pharmaceutical ​Drug​s. I ​ Don't have a​ problem with hair loss sufferers saving money by purchasing cheap generic ​Drug​s on​ the​ internet,​ but I ​ feel strongly that they should at​ least seek confirmation from their physician that a​ given ​Drug​ matches their individual needs.
Before examining the​ most common causes of​ premature hair loss we​ need to​ understand that some shedding of​ hair is​ perfectly normal. Hairs grow from follicles that are tiny organs in​ the​ skin designed to​ grow a​ single hair that follows this repetitive cycle
1. Lengthy growth period Anagen Stage this phase usually lasts between two and seven years with an average growth rate of​ six inches 15cm each year.
2. Short transition period Catagen Stage this period of​ transition lasts for​ roughly two to​ four weeks. During this phase the​ hair shaft becomes detached and moves upwards within the​ follicle.
3. Resting period Telogen Stage this phase lasts about three months allowing the​ hair to​ detach itself prior to​ falling out.
At this point a​ new hair begins to​ grow thus repeating the​ normal cycle of​ hair growth. Unfortunately a​ number of​ factors can interfere with the​ natural hair growth process leading to​ forms of​ hair thinning or​ premature baldness.
Androgenetic alopecia is​ the​ most common cause of​ hair loss,​ probably accounting for​ as​ much as​ 95% of​ pattern hair loss for​ both men and women. it​ is​ usually associated with aging and develops in​ predictable stages over varying periods of​ time. Each follicle follows a​ genetically programmed growth cycle with some follicles coded to​ remain active for​ a​ shorter time than others. This results in​ the​ development of​ the​ hereditary baldness patterns that are so familiar to​ us all.
For this type of​ baldness to​ occur,​ the​ following factors must be present
1. a​ genetic predisposition for​ hair loss to​ occur as​ explained above.
2. the​ presence of​ male hormones.
3. Aging in​ other words,​ enough time for​ the​ first two factors to​ exert an influence.
All men and women produce male hormones such as​ testosterone and DHT. These have a​ useful role to​ play in​ both sexes but obviously occur in​ widely differing concentrations. it​ is​ the​ higher levels of​ androgens found in​ males that explains why this form of​ hair loss affects men more than women.
In brief,​ these hormones affect the​ hair growth cycle as​ follows
1. High levels of​ the​ 5alphareductase enzyme occur in​ some cells of​ the​ hair follicle and sebaceous glands.
2. 5alphareductase converts testosterone into DHT.
3. DHT causes the​ terminal hairs to​ miniaturize.
4. This leaves short,​ soft,​ fluffy vellus hairs that provide inadequate scalp coverage.
5. the​ growth phases gradually become shorter until these hairs are lost for​ good.
Alopecia areata is​ thought to​ be an immune system disorder that causes follicles to​ stop producing hairs in​ patches on​ the​ head. in​ severe cases it​ can advance to​ the​ stage where all hair on​ the​ head is​ lost alopecia totalis or​ even a​ complete absence of​ body hair results alopecia universalis.
In most cases the​ hair will reappear on​ its own but until then,​ the​ condition can be very distressing to​ sufferers particularly as​ its cause can be difficult to​ determine. if​ you​ feel you​ may be suffering from this form of​ hair loss,​ seek the​ advice of​ your physician who will carry out a​ physical examination and conduct blood tests to​ help determine the​ cause.
Telogen effluvium is​ characterized by a​ general thinning or​ shedding of​ hair over a​ period of​ months and is​ most commonly found in​ people who have recently experienced trauma. Common causes include childbirth,​ major surgery,​ severe illness,​ psychological stress and chemotherapy. the​ good news is​ that the​ abnormal growth behavior associated with telogen effluvium is​ temporary and reversible.
There are numerous other less common hair loss causes that need to​ be discounted before a​ course of​ treatment is​ chosen. Traction alopecia is​ the​ loss of​ hair from constant pulling,​ usually as​ the​ result of​ hair styling. Broken hairs can result in​ thinning,​ often caused by excessive styling or​ exposure to​ chemicals and sun. Finally,​ severe illnesses or​ nutritional deficiencies can cause side effects that may include degrees of​ hair loss.
I hope this brief article has gotten across the​ message that diagnosing the​ real causes of​ hair loss is​ not always a​ straightforward process. Once you​ and your physician have identified a​ cause,​ then you​ can work towards restoring your hair to​ its former glory. And the​ good news is,​ most forms of​ hair loss can be treated successfully. the​ next article in​ this series will look at​ some of​ the​ best hair loss treatments currently available.
