What is "ghost shaving"?

"Ghosts shave their heads" is a folk saying, and they often suddenly find that their hair has been turned around, as if it had been shaved by something. ...

So there is a saying that "ghosts shave their heads", which is actually a disease called alopecia areata.

Alopecia areata is a sudden patchy alopecia, which can be one place or many places. To put it bluntly, it is a common and serious hair loss.

Generally speaking, human hair can grow about 0.3 mm a day, one month 1 cm. In addition, hair generally falls off about 50- 100 every day, so hair loss is normal, but if it is much more than this, we should pay attention to whether it is hair loss.

Although alopecia areata seems quite sudden, it is really not necessarily sudden baldness. It's just that early patients basically don't feel it, and there are no obvious symptoms, but sometimes they itch a little.

Alopecia areata is the most common in young adults, but there are also cases in the elderly and children, so it is still a common phenomenon.

What symptom is alopecia areata?

Compared with general alopecia, alopecia areata usually occurs suddenly and local alopecia is obvious; Generally, hair loss is progressive and abnormal, with a wide spread.

Alopecia areata is generally divided into the following categories:

Local alopecia areata: Generally, it is patchy alopecia with no fixed position, but the hair on the scalp edge (especially on the pillow) is not easy to regenerate.

Total baldness: Severe alopecia areata can develop into total hair loss.

General baldness: the whole body hair falls off, even involving eyebrows and armpit hair.

Although alopecia areata looks scary, it actually happens for a reason. Don't believe the folk saying about alopecia areata, and don't be afraid!

What is the cause of alopecia areata?

The etiology of alopecia areata is not completely clear at present, and it is generally believed to be related to heredity, mental stress, endocrine, drugs and autoimmune factors.

At present, mainstream western medicine believes that alopecia areata is an autoimmune disease.

In other words, the patient's immune system is disordered, and his immune cells are friends and enemies, so he has to attack the "friendly army", that is, his hair follicle, to put it into a dormant state, so that the hair stops growing or breaking.

In addition, diseases closely related to alopecia areata include thyroid diseases (hyperthyroidism, hypothyroidism, Hashimoto thyroiditis).

Although alopecia areata feels sudden, many of them can actually heal themselves.

How to make alopecia areata heal itself?

If it is because of autoimmune problems, then it needs to be treated according to different severity. In principle, as long as the immune system can correctly identify the enemy and me.

First of all, reduce stress and improve living habits. Excessive mental stress can lead to confusion of immune system and damage to hair.

Also, staying up late is one of the chief culprits of hair loss. Staying up late will make the immune system not get enough rest, so it will produce immune disorder.

Second, keep confidence and hope. Keep a good mood, be less worried, less sad, less worried and less angry.

Third, we should strengthen nutrition intake. Eat more black sesame seeds, walnuts, fish and other foods, and don't be partial to food.

Fourth, take proper care of your hair. Don't dye too often.

However, if alopecia areata is large in area and lasts for a long time, systematic and scientific drug treatment should be considered.

How to treat alopecia areata with drugs?

General treatment drugs are:

External use: 5% minoxidil tincture (Mandy)

Oral drugs: finasteride; Spironolactone, estrogen

It should be noted that systematic use of hormones has certain side effects, such as obesity, hirsutism, and especially sensitive ones can lead to infection.

Therefore, the time and dosage of medication need to be adjusted by experienced doctors according to the condition, not by feeling!

External use of hormones is often very effective, and the scalp is thicker than the skin of other parts of the body, so there are fewer side effects. Occasionally, side effects include telangiectasia and skin atrophy. However, these side effects can gradually subside after drug withdrawal, so don't treat "hormones" as a scourge.

If alopecia areata is caused by thyroid diseases, thyroid-related diseases should generally be given priority.

As for the popular ginger juice for hair care, the effect is very limited, and it is laborious and time-consuming, but it will delay the time of correct treatment, so it is not recommended.

How long does alopecia areata take to recover?

The course of alopecia areata varies from person to person. Mild patients usually recover naturally within six months to one year. However, for patients with serious hair loss and large area, if they seek medical treatment in time, after scientific treatment, most patients will not see the curative effect until about 1-3 months, and they will recover in six months to two years. However, some patients with mild symptoms can recover themselves within 3 months, while those with severe symptoms may take years or even a long time to recover.

Newborn hair is usually sparse, white or curly, indicating that hair is growing again. At this time, we should continue to consolidate treatment and do not stop taking drugs without authorization.

"Ghost shaving" is actually alopecia areata.

It is a common disease.

The treatment of alopecia areata focuses on psychological adjustment.

Drug therapy is often just an auxiliary means.

So the mood is very important!
