Introduce various depilation methods.

With the development of science and technology, there are more and more means of hair removal.

In addition to depilatory cream and waxing, laser depilation, intense pulsed light depilation and electric depilation have also appeared.

It sounds all kinds, and people are always confused and don't know how to get rid of hair.

It's not that mysterious. According to the principle, hair removal methods can be divided into three categories:

The first category: shaving or dissolving some hair exposed on the skin surface, such as shaving knife, depilatory cream, etc.

The second category: pulling out hair roots, such as tweezers, depilators, waxing and sugar depilation;

The third category: using high-tech methods to act on hair follicles, so that hair follicles shrink and hair falls off, such as electric hair removal, laser hair removal, intense pulsed light hair removal and so on.

Regardless of principles for the time being. According to our familiarity, we divide these depilation methods into "common methods" and "high-tech methods" and make some specific explanations.

Including advantages and disadvantages, matters needing attention, etc. So that everyone can get the point.

"Ordinary hair removal" of hair removal technology

Common depilation methods, namely shaver, depilatory cream and waxing.

These hair removal methods are not aimed at hair follicles, so the effect of hair removal cannot be maintained for a long time. You need to repeat the process of hair removal, but the advantages are small side effects, convenience and cheapness.

Depilating pulp

Depilating cream is harmless and painless, so many students choose depilating cream for the first time.

The effective component of depilatory cream is mainly a mixture of thioglycolate and calcium hydroxide.

These chemical components can react with Mao Mao and decompose them directly.

With a slight scraping of the scraper, the depilatory cream was taken away together with the decomposed Mao Mao.

1. Advantages of depilatory cream:

Cheap! Price is always a factor to be considered;

Although depilatory cream is irritating to the skin, it is relatively painless compared with other depilatory methods.

The depilatory cream does not require the color of hair, and it is easy to use. It can be bought home and depilated quickly.

2. Disadvantages of depilatory cream:

Only the upper part of the hair is broken down, and the lower part will grow out soon. So depilatory cream lasts only a little longer than shaving, so you have to use it often.

There is no way to have the "gentle skin feeling" and "depilatory effect" of depilatory cream at the same time. Good results are often more alkaline and more irritating to the skin. Usually it's a little hot, just wash it off, but some will last for an hour or two after washing it off.

Side effects are also common, which may cause dry skin, itching, slight rash and so on.

3. It should be noted that:

Patch testing is needed before large-scale use. See if the test area will turn red, itchy and irritating. If not, it is a more suitable product.

The place where depilatory cream is used should be kept dry and there should be no cracks. At the same time, cover the depilation area with enough depilatory cream.

When applying depilatory cream to your skin, you'd better look at your watch and don't estimate it yourself. There are many similarities between skin and hair, and depilatory cream can slightly decompose the skin. Too short time is easy to decompose and not clean; Too long may cause skin burns.

Don't wipe it with paper when the time is up, scrape it off gently with a matching scraper, and then rinse it with warm water. Then apply a mild moisturizing cream to relieve irritation and do some moisturizing work.

Waxing and hair removal (waxing)

Waxing and hair removal is to stick wax on the tip of Mao Mao and then uproot it. It looks so cool that Pop can watch it all day.

Waxing and hair removal are divided into soft wax and hard wax. They are used in different ways and have their own characteristics.

Soft wax

First, smooth the Mao Mao along the growth direction, then coat it with a thin layer of melted wax, and then cover it with strip paper (cloth) to flatten it.

After a while, tear it off quickly against the direction of hair growth. Pay attention to tear as close as possible to the skin surface.

geotextile

Hard wax is thicker than soft wax, so paper (cloth) is not needed.

After hardening, Mao Mao was sealed in a thick layer of wax, which was equivalent to catching a lot of hair at the same time. You can tear off the same hair ~

Pope likes hard wax for two reasons:

Hard wax is more friendly to sensitive muscles and less painful. Hard wax is not so sticky to the skin, so it won't take away many skin cells when it is torn.

Hard wax can better remove bristles. The wax layer is thick, which can better grasp the hair after hardening, and the tension is large.

1. Advantages of wax removal

The depilation effect is good. After all, uprooting can last for 4 to 6 weeks, and then the hair that grows will become soft.

Wax removal can be used almost anywhere on the body except around the eyes. Any face, bikini line can be used, and some can even be used to repair hairline;

Large coverage area and high efficiency

2. Disadvantages of wax removal:

Pain, there may be redness and slight bleeding, and it may also cause "endogenous growth". In other words, Mao Mao Tou grows downward and slowly forms a red bag. Especially the last few times, or where there is a lot of hair.

Wax removal has some limitations. It can only remove the grown-up Mao Mao, but it can't do anything about the smaller Mao Mao under the skin. Some students saw Mao Mao grow back after a week of hair removal, and there was nothing they could do.

3. It should be noted that:

Smear it along Mao Mao and tear it off Mao Mao's skin.

It is safer to go to a regular hospital to find professionals to do sensitive parts.

In some cases, wax cannot be removed. Such as sunburn, laser, eczema and so on. No waxing. In addition, people with severe varicose veins and particularly sensitive skin should also avoid taking prednisone or steroids.

4/8

Sugar depilation

Large area hair removal, you can use sugar hair removal.

Sugar depilation is the same as waxing, except that the wax is replaced by sugar.

Compared with wax removal, sugar has the advantage that it is not too sticky to the skin, so it will not hurt so much.

Large-scale hair removal generally chooses sugar removal.

However, sensitive muscles should be used with caution, and there will be sensitive stimulation. You can take some antihistamines in advance to prevent this situation.

"High-tech hair removal" of hair removal technology

High-tech hair removal is also called electric hair removal, laser hair removal and enhanced pulsed light hair removal.

These three methods are different from the above common hair removal methods, which directly destroy hair follicles in various ways, hoping to achieve the purpose of "permanent hair removal". However, the current effect is to achieve "permanent hair reduction".

Although it can't be the ultimate, it still brings a lot of convenience to Mao.

6/8

Electric hair removal

Electric hair removal is to insert a probe as thin as a hair directly into the hair follicle.

Then, the "current" or/and "electromagnetic wave" emitted by the probe destroys the hair matrix, making the hair follicle unable to regenerate hair.

The principle is as follows:

The current will cause the matrix cells to electrolyze and produce high concentration of sodium hydroxide, and the cells will be poisoned if they can't stand it.

Electromagnetic waves are like a miniature microwave oven, which cooks the cells in hair follicles. ...

Some electric hair removal is a combination of the above two principles.

1. Advantages of electric hair removal:

The effect is not bad, and it can also permanently reduce hair growth.

Electric hair removal does not need melanin in hair follicles, which means it is effective for hair of any color.

2. Disadvantages of electric hair removal:

This method of electric hair removal is definitely a technical job. It needs to be inserted into the hair follicle to a certain depth and needs professional training.

Inserting one hole at a time is inefficient. This method is inefficient, difficult to operate and seldom used.

Laser hair removal (LHR) and intensified pulsed light (IPL)

These two depilation methods are similar in principle, so let's compare them together.

To understand these two kinds of depilation, we must first understand a concept-"selective photolysis".

Simply put, light with a specific wavelength and pulse width only heats a specific cell tissue and has little effect on other surrounding tissues.

They all use specific light to heat melanin in hair follicles, so that melanin can burn hair follicles and complete hair removal. At the same time, try not to harm other skin tissues.

This is the case with laser hair removal and intensified pulsed light.

The difference between these two methods is that the laser is single wavelength light, while the intensified pulsed light is broad spectrum light with a specific wave band, which is mixed light.

1. Advantages:

Destroy the hair follicle depilation mode and ensure the depilation effect for a long time.

Compared with electric hair removal, the efficiency is much higher.

2. Disadvantages:

It takes many treatments to achieve the ideal hair removal effect. Because, when receiving laser, not all hair follicles have enough melanin to generate heat and self-destruction.

Only people in the "growth period" can do it, and other "degenerated" and "dormant" hairs cannot be pulled out until they reach the growth period again.

There is also melanin in the skin, so there are bound to be some side effects.

The most common are acne and skin color changes. Others include skin burns, swelling around hair follicles, scabbing, purpura and infection. However, these side effects are temporary and can even be recovered after six months of pigmentation.

The ideal situation is "black hair+white skin", which can depilate without causing too much damage to the skin other than hair.

3. Contrast:

The effect of intensified pulsed light hair removal is better than that of laser hair removal. The effect of hair removal is related to three factors: the energy density of light, the size of light spot and the pulse width. The pulse width of intensified pulsed light is wider than that of laser, and the depilation effect is better.

Laser hair removal has less side effects than intensified pulsed light. Because laser hair removal uses a single laser, it has good pertinence; Intense pulsed light is broad-spectrum light, which is more likely to injure the skin by accident.

4. It should be noted that:

Laser peeling and enhanced pulsed light hair removal have good effects, but after all, they directly hurt hair follicles and have the risk of side effects.

Therefore, there are still many places to pay attention to:

Don't be exposed to the sun for at least one month before hair removal, not only to get sunburned, but also to avoid tanning;

You can't use waxed paper to remove hair. You need melanin from hair roots to absorb heat and destroy hair follicles.

Because everyone's skin color and skin condition are different, it is best to have a doctor give you a local test before the first hair removal. See if you will change color, pigmentation and scar.

Be mentally prepared, you can't clean all your hair at once, it takes at least 5~6 times. A complete course of treatment takes about 3~8 weeks. The specific situation depends on the number and color of hair, as well as the color of skin, the area of hair removal and so on;

Laser/enhanced pulsed light should never be used too close to the eyes. Remember to wear goggles if you do it on your face.

If someone tells you that you can use laser/enhanced pulsed light to remove all your hair at once, change hospitals quickly. This practice is very dangerous and must be avoided;

Pope knows how much you want to clean yourself up as soon as possible. No Mao Mao. But after hair removal, it takes 2~3 weeks for your hair to fall off. You need to let your hair fall out patiently. Never pull it out, let alone use wax paper. All these will affect the effect of laser. Scraping is ok, but it must be gentle;

Moisturize and protect yourself from the sun after hair removal. At this time, your skin is very fragile. Don't use perfume or bath with too hot water.
