“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.

Long-Term Results |
Side Effects |
Shaving |
Use a razor and pass over the skin that contains hair. This method removes all of the hair without affecting the hair follicles |
New hair will become hard and dark after shaving because this method merely removes the hair shaft and not hair follicles. The new hair that have grown come from the same follicles. |
2-3 days |
- Need to be done at least once per week
|
Hair still continue to grow fast according to the hair growth cycle |
- Some may experience skin itchiness and irritation
|
Plucking |
Use tweezers to remove hair from the hair follicles. There is a chance that the hair shaft may be only removed and not the follicles. |
New hair will have the same characteristics. Hair with only the shafts removed and not the follicles will cause the new hair to become hard, making the skin prone to Keratosis Pilaris and acne. |
1 - 2 weeks |
- 2 times/month
|
Hair still continue to grow according to the hair growth cycle |
- Injury around the hair follicles
|
Hair Removal Cream |
Apply the hair removal cream on skin and leave it on for a specified period of time. The cream contains corrosive substances that will weaken the hair. Wash or clean the applied area in the same direction as the hair line. |
Hair become thick and hard, and may appear as dark spots around the applied area since only the hair shafts were removed and not the hair follicles. |
2 - 3 days |
- Must be done at least once per week
|
Hair still continue to grow fast. The hair will not be as hard as when using the shaving method. |
- Might result in a skin burn due to the use of chemicals
|
Epilator |
The tip of hair remover will cause the hair shafts to stand up and pull them from the follicles, while removing the follicles at the same time. This method is faster than plucking. |
New hair will have the same characteristics. |
1 - 2 weeks |
Must be done consistently.
|
Hair will continue to grow according to the hair growth cycle. Continuous use of epilator will cause the hair to fall out easily due to the widening of hair follicles. |
- Sharp pain similar to when the hair got plucked
|
Waxing |
Apply cold or hot wax onto the skin. Smooth a cloth strip on top of the wax and remove the strip within the specified time. This technique will remove both the hair and follicles. However, there is a chance that only the hair shafts are removed and not the follicles. |
- New hair will become soft but with the same volume.
|
1 – 2 weeks |
Must be done once a month to ensure a smooth skin |
Hair still continue to grow because this technique doesn’t destroy hair follicles. |

Laser |
Gentle Yag Laser uses a laser beam to attract melanocytes in the follicles. This type of cell will absorb light energy and transform it to heat, thereby destroying the follicles to prevent hair growth, with no effect on the skin. |
- Hair will gradually fall out after the laser.
|
4 weeks depending on the hair condition of each individual. |
- Must be done consistently. Each treatment should be spaced out between 4-6 weeks.
