The duration of hair loss depends on the hair’s growth cycle. Hair grows in two phases – the Catagen phase and the Telogen phase – and at any one time, about 3% of hairs are in this stage. During this time, hair growth slows and the outer root sheath shrinks. This stage is also referred to as club hair.
The Telogen phase of hair thinning is a common cause of hair thinning and is a biological process. This phase is determined by the mitotic activity of the hair follicles and may also be influenced by physiological stress. Hair follicles may remain in this resting state for months or even years.
Telogen effluvium is a temporary hair loss condition. It causes thinning hair and an increase in hair shedding. It usually occurs after a physiologic trigger. The shedding tends to be dramatic, lasting up to three months, though in some cases, the shedding can be chronic. Some medications and lifestyle changes may help treat the symptoms.
Normally, the human hair cycle involves three distinct phases: the anagen (growth) phase, the catagen (resting) phase, and the telogen (resting) phase. The anagen phase lasts from two to eight years, while the telogen phase lasts between two and four months. During the telogen phase, hair follicles cease to grow and fall out.
The outlook for people with Telogen effluvium is good. In most cases, it runs its course within six to nine months. Once this phase is over, the hair begins to regrow again. However, some hairs do not grow back during this period, so it’s important to consult a healthcare provider if you notice any signs.
Some factors contribute to TE, such as diet deficiency and chronic stress. Stress can influence the biochemistry of hair follicles, causing more of them to enter the telogen stage. In some cases, telogen effluvium may also be a symptom of a underlying disorder.
In addition to stress, many factors can contribute to telogen effluvium, including pregnancy, postpartum hair loss, and hormone changes. Some medications, hormone therapies, and environmental toxins may also affect this cycle. Other health conditions that may affect telogen effluvium include hormone imbalance, thyroid disease, and general or local skin diseases.
Doctors can diagnose telogen effluvium by looking at the scalp and hair. Symptoms of the condition include diffuse thinning of hair throughout the scalp. Some sufferers also experience hair loss in other body areas.
Telogen effluvium is a condition in which the telogen phase of hair growth is prematurely prolonged. The result is a period of increased shedding two or three months after the telogen phase ends. While there is no specific treatment for this condition, changes in diet and lifestyle may help to begin the hair regrowth process.
Testing for Telogen Effluvium involves taking a hair sample. The doctor will ask the patient to collect all shedding hair within a 24-hour period. The hair should be kept dry and clean during collection. This process should be repeated three or four times a week. If more than two hundred hairs fall out during each collection, the patient most likely has Telogen Effluvium.
Telogen effluvium is a common condition that causes thinning hair in women. It mostly affects middle-aged women. It is a chronic condition and has an irregular course. It is caused by an anomaly in the usual hair cycle. Various factors can trigger this abnormality, including significant emotional stress.
Hair loss due to Telogen effluvium can occur suddenly, with thinning hair all over the scalp occurring within two or three months. The loss of hair can be dramatic, but normally does not exceed fifty percent of the scalp. Telogen hair is very easy to extract from the vertex and margins of the scalp. This condition is often accompanied by marasmus, a condition characterized by dry, fine hair.
There are a variety of factors that can trigger telogen effluvium, including a severe protein deficiency, a fatty acid deficiency, or severe nutritional or metabolic stress. Various medications and illnesses can also trigger the process.
The most common symptom of telogen effluvium is temporary hair loss. This thinning process is associated with a shortened anagen phase. It usually begins within three months of the triggering event and can last up to six months. Depending on the severity, the shedding process can last as long as a year.
Hair loss caused by TE is a temporary condition and will eventually disappear. Though, there are some protections that can be taken. First, you should avoid products that may cause androgen-induced alopecia.
Age of hair loss
While hair loss occurs in all age groups, there are many factors that influence the onset of hair loss and thinning. In younger people, the body is more receptive to hair-growth products and treatments. This is because follicles may still be able to regenerate. Other factors may be hereditary, stress-related, and related to diet and exercise.
Hair loss is a hereditary trait, and if one parent has the same gene as you, then you are more likely to experience it yourself. For example, men who develop male pattern baldness have a greater risk of balding at age 45. But even if you’re born with male pattern baldness, you can address it early with the right hair loss treatment.
The first step in treating hair loss is identifying the cause. If you’re noticing hair loss at an early age, consult with your doctor. This will help determine whether it’s a symptom of a bigger problem or just a simple diet change. You should also avoid smoking and alcohol in moderation.
Extreme emotional and physical stress is another factor that can cause hair loss and thinning. This can include extreme weight loss, surgery, anemia, or the loss of a loved one. Similarly, excessive exposure to UV rays can damage your hair. Fortunately, you can take precautions by wearing hats and using hair products with sunscreen. Other medical conditions that may cause hair loss and thinning include anemia and hypothyroidism.
Hair loss can also be caused by an autoimmune disease. These autoimmune diseases can cause your body’s immune system to attack your hair. They can be reversible if diagnosed early. If you’re not sure if you have this condition, consult a dermatologist. A doctor can perform a scalp biopsy if necessary.
Catagen is the transitional stage between the growth and resting phases of the hair follicle. During this stage, hair cells begin to shrink and the bulb becomes shorter and smaller. The follicle then moves upwards in the dermis and becomes a club-like structure.
The follicle is surrounded by an epithelial cap. Apoptosis of the dermal matrix and the inner and outer root sheath occurs during this phase. The resulting epithelial strand resembles the dermal papilla.
As you age, your hair grows at a different rate. It may be thinner or thicker in some areas. But in general, about eighty to ninety percent of your hair will be in this phase at any given time. This is the natural process that all hair follicles go through.
Catagen phase of hair thinning is caused by an abnormally long time between the growth cycle and the resting phase. The resting phase, or telogen, is the stage when the hair follicles stop producing new hair. Hair follicles will remain in this state for two to three months, and then shed.
This period is commonly caused by hormonal or metabolic changes in the body. The body may produce cytokines that trigger the release of anagen, or TE. These hormones cause hair follicle keratinocytes to undergo apoptosis. During this phase, hair follicles will start shedding excessively.
