Comparing 6 Techniques of Hair Removal –Which Techniques are Safe and Gentle to the Skin?

“Excessive Hair” – the main cause of a lack of confidence 

Apart from genetics that indicate the amount of “hair” covering the body, “hormone” is another important cause of hair in men and women. In early adolescence, there are some changes in the body, including an increase in the amount of “hair”, darker hair, and thicker hair. This is due to the body producing testosterone higher than normal before reaching puberty, which can occur in both men and women. Some even want to eliminate all hair out of the body.

 

Understand the Components of “Hair”

1. Hair Follicles
are part of the epidermis and dermis. They are found below the surface of the skin and form a tube surrounding “hair root”. Hair follicles are attached to the “sebaceous gland” that is responsible for maintaining the balance and hydrating the skin. If the hair follicles are disturbed, the “sebaceous gland” will release sebum to cover the skin and maintain the balance. Hair follicles have different characteristics, depending on the location of hair.   

2. Hair Bulb 
It can be observed that hair shafts that lean towards the same direction are the result of “hair bulb”, which is an important origin of hair. Hair bulb is embedded under the skin in a slightly “diagonal” direction. It has a bulb-shaped structure with part of the dermis stretching into the bulb.


3. Hair Shaft 
is the portion of hair that extends through the skin. The hair shaft of each individual will have different growth and characteristics, depending on each individual’s body mechanism including hormone, nationality, and genetics.

Hair Growth Cycle

Normally, there are three phases of hair growth cycle, starting from the anagen phase to catagen phase, then ended in the telogen phase. The cycle will then be repeated, returning back to the anagen phase and so on. As you get older, each phase will be slower correspondingly. The three stages of hair growth cycle are as follow: 

1. Anagen Phase
This phase is when the hair reaches its full growth, with the hair structure being fully developed. Each hair will have a lifespan of approximately 2-3 years, considering no external factors that cause the hair to fall out and disrupt the growth stage. As we get older, the length of anagen phase becomes shorter. Some may even experience hair thinning. 


2. Catagen Phase
This phase occurs at the end of anagen phase. It is the stage that signals the end of hair growth with the hair being ready to fall out from the follicles. This phase lasts approximately 2-3 weeks. 

3. Telogen Phase
This phase continues from the catagen phase, in which the hair is released and falls out. This phase lasts about 3-4 months before the whole process is repeated, returning back to the growth stage.

Types of “Hair”

1. Lanugo Hair : is a very thin and soft hair with no pigment or color. This type of hair is commonly found in fetus.ไปแล้ว

2. Vellus Hair : is a thin and short hair, slightly colored. It is commonly found on the face, neck, and body of women. Likewise, it is also partially found at the hairline. This type of hair will replace the lanugo hair and has a lifespan of approximately 3-4 months.

3. Androgenic Hair : Once entering the adolescence, androgenic hair will replace the vellus hair. This type of hair is thick and dark in color, and is found in some parts of the body such as eyelashes, eyebrows, and underarm hair. Its lifespan is about 5 months.

Comparing 6 “Hair Removal Techniques”

Currently, there are many hair removal methods, including a method that we can do by ourselves and a method that involves medical procedures. Today, SLC will provide you with a comparison between each “hair removal” technique to help you decide the most suitable technique for you that is effective, gentle to the skin, and corresponds to your needs.
