Does Diode Laser Hair Removal Work?——Explore the Origin of Hair


Hair serves as a prominent reservoir for individual genetic information, accurately reflecting changes in physiological states. Each strand offers an enigmatic glimpse into the genesis of life, illuminating the complexity of physiological evolution. Society’s advancement is paralleled with evolving aesthetic ideals, resulting in increased interest in hair management – notably, hair removal technology. Among various techniques aimed at eliminating unnecessary follicles, diode laser hair removal has garnered considerable praise for its efficiency and precision attributes. Given this acclaim, it prompts us to scrutinize its effectiveness further: Is diode laser hair removal genuinely efficacious? Nonetheless, before engaging this question in depth lies the necessity to thoroughly comprehend the origins of hair growth cycles and their relationship with distinct follicle elimination methodologies.

Introduction of hair

Hair is the last barrier of the human body. Although its protective function has been gradually replaced by clothing in modern society, the significance of its existence is far more than that. The number, color, texture and other characteristics of hair are largely influenced by genetic factors and androgen. Each person’s hair has its own unique growth pattern and cycle, which is why hair growth varies from person to person.

From a physiological perspective, the role of hair is not solely confined to protection. Despite modern developments such as clothing supplanting hair’s protective function, hair continues to contribute towards heat regulation and secretion activities. However, these roles serve more as support systems complementing other skin functions rather than being essential components themselves. The primary facilitators are, in fact, the skin pores. Provided that these pores maintain their functionalities effectively, the absence of hair would not influence the sebaceous glands’ secretory processes or impede the skin’s ability for thermo-regulation significantly.



Origin of hair

The emergence of hair is indeed an intriguing phenomenon. Human hair originates from a layer in the embryo known as the ectoderm and undergoes an intricate process characterized by growth and differentiation which eventually results in the formation of follicles and discernible hairs that we observe today. Primitive epithelial germs are principal contributors to this process wherein they experience a series of cell divisions and differentiate subsequently, cultivating distinctively structured and functioning hair follicles over time.

During fetal development, fetal hairs are the first type of hair to appear. They first appear in the fourth month of fetal life and are mainly found on the head and face. As the pregnancy progresses, the lanugo hairs gradually spread throughout the body, providing some protection for the fetus. However, when the fetus is born, these lanugo hairs are gradually replaced by more mature villi and terminal hairs. This process is a natural physiological change and is part of human growth and development.

It is important to note that the human body does not form new hair follicles after birth. This means that the number of hair follicles in each of us is determined at birth and does not increase with age. Therefore, this is certainly disappointing news for those who wish to reduce the number of hair follicles through hair removal. However, this does not mean that we cannot change the condition of the hair. With several modern hair removal techniques, we can effectively reduce the number and density of hairs to improve their appearance.

The hair follicle, the site of hair growth, has a complex and delicate structure. It is like a slender pocket that penetrates deep into the dermis and subcutaneous fat layer of the skin. The interior of the follicle is filled with important cell types such as trichoblasts and melanocytes, which work together to maintain hair growth and pigmentation. The follicle is also surrounded by a rich distribution of blood vessels and nerves, which provide the hair with adequate nutrition and growth signals.

Hair growth cycle

After understanding the origin and structure of hair, let’s take a look at the growth cycle of hair. The hair growth cycle is usually divided into three phases: anagen, anagen and telogen. During the anagen phase, hairs are actively growing, increasing in length and diameter; during the anagen phase, hair growth slows down and gradually stops; and during the resting phase, hairs begin to fall out in preparation for a new growth cycle. This cycle repeats itself and constitutes the dynamic change of hair on our body.



Diode laser hair removal principles and results

Let’s explore the principles and effects of diode laser hair removal. Diode laser hair removal technology utilizes laser energy to destroy the hair mother cells in the hair follicle, thus inhibiting hair growth. Since the laser energy can act precisely on the hair follicles without damaging the surrounding skin tissues, this type of hair removal is highly efficient and safe. Under the action of the laser, the hair follicle’s hair mother cells are damaged and are unable to divide and differentiate normally, thus inhibiting the growth of hair.

However, it should be noted that diode laser hair removal is not a one-and-done solution. Due to the existence of a hair growth cycle, even after laser hair removal treatment, there is still a possibility that new hairs may appear after some time. In addition, hair growth and physical differences in different people can also affect the results of hair removal. Therefore, when choosing a hair removal method, it is recommended to choose according to individual circumstances and under the guidance of a professional doctor or skin specialist.




The efficacy of diode laser hair removal as a contemporary technique for hair reduction is notably significant to some degree. Nonetheless, it is essential to acknowledge that the impact on hair reduction can vary significantly, contingent on each individual’s distinct body type and hair condition. As we seek aesthetic enhancement, attention must equally be given to our physical health and safety. A comprehensive understanding of our bodily conditions and the specific characteristics of our hair will guide us toward selecting an optimal method for hair removal. This informed decision facilitates the dual achievement of enhancing aesthetic appeal while sustaining good health.
