Today, we will explore various methods and suggestions for hair removal to help you choose the most suitable method for yourself.

On the market, there are many different hair removal methods, with the most common being plucking, shaving, and depilatory creams. The most traditional method is to use tweezers to pluck the hair directly. Among these options, plucking is the only method that can remove the hair root, resulting in less remaining keratin and a longer lasting effect. In contrast, shaving only trims the surface hair, which lasts for a relatively shorter period of time.

In beauty salons, waxing is a popular choice. This method involves applying a wax-like substance that solidifies and is then quickly ripped off to remove the hair. Although this method is convenient, it may lead to side effects such as folliculitis or contact dermatitis. There have been cases where patients suffered serious chemical burns from using wax or chemical depilatory products, so caution is advised when making this choice.

Before preparing for this topic, I asked several friends about their experiences with hair removal products. Many indicated that they had purchased at-home hair removal devices, but in reality, there is a higher prevalence of using intense pulsed light (IPL) technology. However, these products often do not provide detailed information about the laser’s energy, pulse width, and cooling methods in their manuals, leading to confusion among consumers. For example, some brands claim their energy can reach 12 joules, which may cause discomfort for general home users.

When using these at-home hair removal devices, recommendations regarding the frequency of use vary widely—some suggest intervals of four weeks, while others advocate for multiple sessions each week. These differences may relate to the power of the devices. Some high-power products provide better hair removal results but may also cause greater discomfort.

In the professional medical field, laser hair removal is widely used. There are primarily two common techniques: IPL and Alexandrite laser. IPL provides a more comfortable treatment as it has a cooling feature. In contrast, the Alexandrite laser targets the melanin in the hair and focuses on removing hair in the growth phase. The best time for hair removal is when the hair is in the growth stage, as this achieves the best results. During each treatment session, approximately 15% to 30% of the hair is destroyed, which is why multiple treatments are necessary.

Using lasers for hair removal can consistently eliminate hair in the growth phase, making hair nearly invisible in your daily life. However, because hair follicles may sometimes enter the resting phase, it is essential to maintain continuous treatment in order to achieve ideal results as new hair grows.

It is important to note that the wavelength of Alexandrite laser is 755nm, while IPL has a broader range of wavelengths. This means that each patient’s skin characteristics need to be carefully considered. Therefore, a doctor’s expertise is crucial during the procedure; incorrect operations may lead to burns, pigmentation, even blisters, and scars.

Historically, hair removal techniques can be traced back to early electrolysis, which has gradually been phased out over time. Currently, the medical community has a relatively lenient definition of permanent hair removal, focusing more on whether a hair-free state can be maintained within a hair growth cycle.

In summary, while hair removal has a long history, technological advancements have led to increasingly diverse options. The most effective way remains through professional laser hair removal to achieve lasting results.
