Diffuse Alopecia

Relating to a specific form of diffuse alopecia – eviction of hairs hafts that have prematurely entered the telogen phase. Excessive loss of hair can occur. Telogen Effluvium tends to become apparent 6-12 weeks following the cause. Such a hair loss can result in 1-2cm stubble in extreme cases within weeks. Causes include: Pyrexia (body temperature reaching 103.5 C +),  Childbirth (rare),  severe infection (especially toxaemia), major surgery, protein deficiency due to unsupervised crash diets,  drugs including beta blockers, anti-depressants, severe psychological stress.

Acute Telogen Effluvium

Telogen Effluvium affects patients either acutely or Chronically. This acute Hair Loss causes rapid hair shedding within a short space of time. This could happen over a period of days or a few weeks. Often patients as a result will reduce the washing regiment in the hope that this will stop the hair falling out. If you don’t wash your hair thoroughly, you will lose more hair! Often the quicker you shed hair the faster you will recover. As mentioned above your hair may well grow back without treatment. However, it may need some help. Causes of such ailments include major shock to the body, dramatic temperature change, infection etc.

Chronic Telogen Effluvium

This is a term to describe a gradual hair loss over a period of time. Perhaps months or even years. This will often not be noticeable in the first instance. Patients should seek professional help to determine a cause. Low Iron is often a contributing factor.

The Hair Growth Cycle

In order to fully understand the factors surrounding anagen and telogen effluvium it is necessary to know the stages of hair growth in hair cycle. Scalp hair follicles have a four phase cycle. Anagen (growth), Catagen (transition), Telogen (resting) and Exogen (hair-shaft evacuation). This cycle refers to all hair types including afro.

The Anagen Phase

During the process of folliculo-regenesis, the follicle + epithelial sheath + new hair shaft is recreated. During the growth (anagen) phase the hair shaft continues to gain length for a period of 2-7 years. Approximately 80-85% of hair follicles are in anagen. Hair growth rates range from 0.5cm – 1.45cm per month. We are discussing the scalp hair here. Other regions of the body will grow for a shorter time period for instance the eyebrows which take around 3-4 months.

The Catagen Phase

mitosis ceases, the follicle enters a period of degeneration. Catagen accounts for approximately 3% of hair follicles. The Epithelial sheath shrinks forming a minute “club root” at the proximal end of the hair shaft. Catagen lasts for approximately 10-20 days.

The Telogen Phase

approximately 12-20% of hairshafts are in the amitotic (resting) phase. Eventually (up to 3 months ) the hair shaft vacates the follicle. Remember what I said above? It is a gamble to wait and see what happens to the hair.

The Exogen Phase

 in which the hair-shaft is evacuated. The hair leaves the follicle allowing the new hair to grow freely. This is an important part to remember. It is the washing that assists the hair to fall. If you don’t wash correctly, this can affect the hair shedding thus affecting the rate of hair loss.

Anagen Effluvium 

Hair loss during the anagen phase of the hair cycle. Remember that the anagen phase is the growth phase.  – The onset may be rapid (within 2-4 weeks of the cause). Hair loss may be severe. Causes include:-  Chemotherapy drugs (antimitotic agents), Radiotherapy, Malnutrition, Seborrhoeic dermatitis, Oral contraceptives, Vitamin A poisoning, Iron deficiency, Chronic infections and some drugs. 

Patients suffering from anagen effluvium will almost certainly have other symptoms. This condition affects patients that have health issues. In any case of anagen effluvium you should seek professional advice.
