We all know that hair plays a key role in adding beauty to our face. Different hair styles and hair cuts gives us different stylish looks. For this same reason we love and care for our hair so much. Even a slight damage to the hair would hurt us deeply. Let us see some of the some the common problems effecting the normal hair growth and development.
A normal healthy individual may lose up to hundred hair per day. If you experience hair lose in excess then this indicates an unhealthy situation. Uncontrolled hair fall may eventually lead to baldness. Hair loss may be permanent or temporary.
There are four major types of temporary hair loss. They are Alopecia areata, Telogen effluvium, Traction alopecia, Anagen effluvium. In Alopecia areata, the hair loss occurs in small round patches and as a result few bare patches can be seen on the scalp. The Telogen effluvium type of hair loss occurs due to some disease or illness. This leads to overall hair thinning but does not lead to baldness. In Traction alopecia, the hair fall occurs due to stress imposed by repeated use of certain hairstyles like high pony tails, braids, those involving the use of tight rollers etc. In this case more hair will be pulled out from the area which receives constant stress. The Anagen effluvium type of hair loss occurs in cancer patients who had under gone chemotherapy recently. The drugs used in chemotherapy acts against actively growing cells of the body including the actively growing hair strands. Few weeks after chemotherapy, the hair starts growing. Hair loss may also occur during the pregnancy.
The permanent hair loss is of three major types. They are Male pattern baldness, Female pattern baldness and Cicatricial alopecia. The Male pattern baldness or the androgenetic alopecia occurs due to two factors, they are heredity and the presence of male sex hormone androgen. Here excess hair los occurs in the top portion of the head. This type of baldness may begin even in the early 20’s and may finally lead to partial or in some cases complete baldness. The Female pattern baldness or the androgenetic alopecia is seen in females. Here the hair loss may occur in the front, sides or crown region of head. The last type of permanent hair loss is the Cicatrial alopecia which is seen very rarely. Here the hair loss occurs as a result of inflammation of the hair follicles.
Itching in the scalp is quite irritating. The two main causes for itchy scalp are :
The most common reason for the itchy scalp is the presence of dandruff. It is normal to shed dead cells. These dead cells that sheds off from the scalp as aggravates are usually too small and not visible. But in some abnormal condition the dead cells may be easily visible as they get shed off as larger aggravates. This abnormal condition is due to dandruff. White flakes of on the scalp, hair and shoulders are all symptoms of dandruff. The production of white flakes is often accompanied with an itching scalp. Dandruff is common in people within the age group of 10- 85. The dandruff is mostly caused by a fungal infection. The fungus responsible for this is Malassezia furfur. Other major causes for dandruff are the dry skin, Psoriasis, eczema, inadequate cleaning and shampooing
The head lice is another major factor responsible for itchy scalp. This is commonly seen in school going children especially in girls. Head lice are a small parasitic insect. The louse feeds on blood and it does so by sucking blood from the scalp. This results in infection of the scalp followed by itchy sensation. This condition is known as Pediculosis capitis. This commonly spreads through close contact with affected individual and through sharing of personal belongings like bath towel, comb, dress, pillow etc. The itchy sensation is due to an allergic reaction to the lice saliva. The lice inject this to the scalp while feeding on it for blood. The itching is accompanied with red bump formation like patchy. Apart from scalp it may also affect neck and shoulder. There are medications available to control the head lice.
Graying of hair is generally considered as a sign of aging, but in some people graying of hair occurs much earlier even during the teenage period. The genetic predisposition of an individual plays a great role in the graying of the hair. Other major causes are emotional stress, certain health conditions like anemia, thyroid gland malfunctioning etc. are best way to over come this and through hair coloring or hair dyeing.
Split ends are another commonly seen hair problem. The symptoms of split ends include dryness of hair strands accompanied with spits towards the end. Over use of hair treatments like coloring, perming, blow drying etc. along with lack of proper conditioning are the major cause for split end formation.
The frizzy hair is a condition that affects curly and wavy hair. This is characterized by hair dryness and breakage. The frizzy hair are caused mainly due to severe drop in hair moisture level. Too much usage of hair dryers to dry up or straightening your hair and combing can also lead to frizzy hair.
