Hair Loss: What Happens Exactly
Men and women have between 100,000 and 150,000 hair strands on their heads. The number of strands normally lost in a day would average to 100. Anything more than 100 hair strands is not normal and is most likely an indicator of hair loss. To prevent hair loss, hair must be replaced at the same rate at which it is lost.

Hair grows in different cycles: anagen, catagen, and telogen. 90% of your hair is in the growth phase or anagen, this lasts from two to eight years. Catagen typically lasts about two to three weeks where your hair is in the transition phase. Your hair rests for around two to four months in the telogen cycle. Majority of the time your hair is on your scalp, it is growing. Hair grows about 6 inches a year for many people.
One of the most common signs of hair loss is when there are more hair left in your brush or the bathroom drain than usual. Patches on your scalp[1] that no longer have hair is another sign of hair loss. These patches are sometimes visible even when you style your hair or get a haircut. Hair loss is often health-related, so chances are, it is reversible. If something is not quite right with your body, that problem may cause your hair to thin and fall. Note that each follicle has its own life cycle and that many factors affect hair growth.
Hair loss isn’t irreversible. It may take time and effort, but with the help of a good diet, hair care habits, and the best hair loss shampoo, all the work is worth it.
Common Causes of Hair Loss
Decreased hair growth and hair strand breakage are two common ways you may experience hair loss. The list of causes for both includes diseases and poor diet. It could also be because hair mostly is just thin because of genetic predisposition and aging.
There are three main reasons for hair loss. The most common are hormones, more specifically the rising levels of dihydrotestosterone or DHT. Another cause is trauma or stress. Stressful life events can lead hair follicles to stop growing prematurely. The third reason for hair loss is medical issues[2].
Other causes include:
- Inherited hair loss (male- or female-patterned hair loss) – DHT and poor blood circulation on the scalp can be inherited genetically.
- Physical and emotional stress – Any kind of trauma whether physical or emotional can trigger hair loss.
- Age – It’s not uncommon to see hair loss or hair thinning in women and men as they enter their 50s and 60s.
- Pregnancy and hormonal changes – Just as pregnancy hormone changes can cause hair loss, so can switching, starting, or going off birth-control pills.
- Medication or medical treatments – Chemotherapy can cause hair loss. It destroys rapidly dividing cells. That means cancer cells but also, rapidly dividing cells like hair. Certain types of medication may also cause hair loss. More common among them are certain blood thinners and blood-pressure drugs known as beta-blockers.
- Styling – Extreme styling and hair treatments over the years can cause your hair to fall out. Examples of extreme styling include tight braids, hair weaves, or cornrows. Chemical relaxers to straighten your hair, hot-oil treatments, or any kind of harsh chemical or high heat can cause hair to fall or break prematurely.
- Poor diet – A diet with too much Vitamin A or lack of protein and Vitamin B may cause hair loss.
- Illnesses and disease – Hyperthyroidism, lupus, cancer, and HIV infection can all cause hair fall. Most of the time hair may grow back once a person is able to manage his or her illness with the right medication.
Gender Differences
Hair loss and hair thinning occur for about 60% of men by age 50 and 40% of women by the age 40. More women suffer hair loss than you think even if hair loss is more prevalent in men. Men start having receding hairline even when they are still young. This gradually transitions to complete baldness. Women tend to lose hair on their crown but rarely does it result to baldness unless caused by medications or disease.
Fortunately, hair loss is treatable[3]. When treated early, you can slow down or stop hair loss. This is true for both men and women.
Effects of Hair Loss
The world often sees luscious and thick hair as a sign of youth, attractiveness, and good health. It follows that people who don’t have hair are perceived as the opposite. Hair loss not only takes away your precious hair but is also psychologically detrimental. The way people perceive themselves hangs in the balance when they suffer hair loss. The hair loss effects[4] may include:
- Depression and introversion
- Fear of not being attractive to others
- Few styling options
- Loss of confidence
- Low self-esteem
- Looking older than your age
Since hair is a secondary sexual characteristic, losing hair may lead to losing the feeling of attractiveness. A negative body image affects the person’s social life and idea self-love.
