HAIR LOSS CLINIC
Every day 50 to 100 hairs fall out so do not worry as this is normal. However, if you are losing an abnormal amount of hair and you are worried, it is better to see a specialist because time is of the essence in tackling hair loss for men and for women.
The issue is that when you suffer from excessive hair loss, it will take time before it becomes visible with a naked eye. In fact, the average number of hairs on a scalp is 100 000 so you will not notice the issue straightaway. Here, we will try to give you a better understanding of the hair cycles.
The Hair Cycles
It is widely accepted that the Hair is a four-stage cycle: It starts with an active growth cycle called the Anagen phase followed by a regression cycle called the Catagen phase, a resting phase called Telogen, and finally a shedding cycle called the Exogen phase.
On average, 85/90 percent of one’s hair is growing at any given time, while 10/15 percent is at rest. Normally, the growth cycle lasts from two to six years; resting takes about three months.
These stages of hair growth are studied in great depth to better understand how hair grows and what might be done to prevent or treat premature hair loss. The first three phases — anagen, catagen, and telogen — cover the growth and maturation of hair and the activity of the hair follicles that produce individual hairs. During the final phase, exogen, some hair sheds, but usually, new hairs are getting ready to take their place.
Each phase has its own timeline, which can be affected by age, nutrition, and overall health.
1. Anagen: Growing phase
First, the stages of hair growth begin with the anagen phase. In fact, this is the longest phase, lasting about 2 to 6 years and also known as the “active” or “growth” phase.
During the anagen phase, your hair follicles are pushing out hairs that will continue to grow (about half an inch each month) until they are cut or reach the end of their lifespan and simply fall out.
At any time, about 85/90% of the hair follicles on your scalp are in the anagen phase.
2. Catagen: Transition phase
Secondly, the catagen phase starts when the anagen phase ends, and tends to last about 10 days or so. During this cycle, hair follicles shrink and hair growth slows. The hair also separates from the bottom of the hair follicle, yet remains in place during its final days of growing.
Only about 5 percent of the hair follicles on your scalp are in the catagen phase at any given time.
3. Telogen: Resting phase
Thirdly, the telogen phase typically lasts around 3 months. An estimated 10 to 15 percent of your hair follicles are in this phase.
It is also called “resting” because the hairs don’t grow during the telogen phase, but they don’t usually fall out either. The telogen phase is also when new hairs start to form in follicles that have just released hairs during the catagen phase.
Many experts consider the telogen phase the shedding phase, as well, but many scientists have divided this stage into two parts: the telogen and exogen stages.
4. Exogen: Shedding phase
Finally, the exogen phase is essentially a “continuity” of the telogen stage of hair growth. During the exogen phase, hair is shed but losing 50 to 100 hairs per day is normal.
This cycle can last about 2 to 5 months, new hair follicles are growing, and “older” hairs fall away.
More than hair, it is about the follicle
The hair itself is dead: it is composed of dead keratino-cytes (trichocytes), which are compacted into a fiber of incredible tensile strength, the hair shaft. The living part that matters is the follicle, in the scalp, from which the hair spring. In fact, the hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides, and immune cells. It resides in the dermal layer of the skin and is made up of 20 different cell types.
Several factors can cause hair loss
Hair loss affects both sexes with incidence increasing with age.
In men, male pattern-balding (androgenetic alopecia) is caused by the male hormone androgen and has a specific pattern of regression in the front and on the sides. Androgenetic alopecia is of significance in about 12 percent of men aged 25, 37 percent of men aged 35, 45 percent of men aged 45, and about 65 percent of men aged 65, increasing only slightly thereafter.
Its counterpart in Women called female pattern hair loss causes generally diffuse hair thinning. Hair thinning in women is commonly related to menopause and other age-related changes. This said women can also suffer from female-pattern baldness with hair becoming less dense and some part of the scalp may become visible.
Triggers for hair loss include (but are not limited to) everything from hormonal shifts, stress and emotional trauma, illness, overuse of hot tools or chemical treatments, diet, and, of course, ageing.
For everyone, ageing exacerbates the hair-loss problem. Hair strands become smaller and have less pigment. The cycles of hair follicles are exposed to a substantial number of extrinsic and intrinsic stressors. As the hair follicle sits deep within the dermis with its bulb residing in the hypodermis, some age-related changes in the surrounding scalp skin may disrupt the hair follicle’s normal cycles. Some evidence suggests that scalp skin aging and hair follicle aging go hand-in-hand.
Stress – primarily in the very severe forms accompanying high fever, surgery, or emotional trauma – can also trigger more of the rest cycle for hair than is normal.
Furthermore, we as can also count a variety of other factors such as diet and even tight hairstyle.
Indeed, damages or even destruction of hair follicles destruction can be the result of physical trauma, sustained burns, and chronic hair-pulling; bacterial or viral infections. Additionally, hair loss that results from dietary deficiencies, stress, drugs and even damaging hairstyles.
Diet is another critical factor because hair is 98 percent protein. The lack of protein may send hair into the resting phase, and, after a while, create substantial shedding. That is why, for instance, Vegetarians should look for nonmeat sources of protein.
It’s not the weight loss diet that causes hair loss per se but the fact that some people go for three to six weeks without adequate protein.
Hair needs particular vitamins, such as the B-group, and minerals, including zinc and iron (some women can lack iron by heavy menstrual bleeding). Therefore, you can look at a multivitamin supplement (with added minerals) and even take biotin shots (vitamin B7). However, beware that very high levels of vitamin A can potentially lead to hair loss.
Pregnancy & birth-control pills
During pregnancy or if taking birth-control pills, most of the hair is in the resting phase. After delivery, or quitting the pill, then the cycle returns to normal, meaning that hair that should have been shed before, now occurs. It is a natural phenomenon but nevertheless potentially stressful to women unprepared for this occurrence.
