Why Facial Hair Grows Faster Than Body Hair

Have you ever wondered why facial hair grows faster than body hair? Despite the popularity of laser hair removal, it may work more slowly on the face compared to other parts of the body. In this blog, we’ll explore the science behind the growth of facial hair and why laser hair removal may be more challenging for this area.

Hair Thickness

One reason why laser hair removal may work more quickly on the body and more slowly on the face is due to hair thickness. Body hair tends to be thicker and coarser than facial hair, making it easier for the laser to target and destroy the hair follicle. Thicker hair absorbs more energy from the laser, resulting in a more effective treatment.

Skin Color

Another factor that affects the effectiveness of laser hair removal is skin color. The laser targets the pigment in the hair follicle, which means that the surrounding skin may also be affected if it is also pigmented. This is more likely to occur in darker skin tones, making laser hair removal on facial hair more challenging. The skin on the face is more delicate and has more variable pigmentation, which can make it more difficult to target the hair follicles without causing damage to the skin.


Hormonal changes can also play a role in how effective laser hair removal is on different areas of the body. Hormones can affect hair growth and thickness, and they may be more pronounced in facial hair growth patterns. The growth of facial hair is influenced by androgens, which are male sex hormones. Testosterone is the primary androgen responsible for the development of facial hair, and during puberty, its levels increase in males, triggering the development of secondary sex characteristics such as facial hair growth.

Androgens stimulate hair follicles to produce thicker and coarser hair, but the distribution of hair follicles and the type of hair they produce is genetically determined. This is why some men are able to grow full beards while others have patchy or sparse facial hair. In addition to testosterone, other hormones such as dihydrotestosterone (DHT) can also contribute to the growth of facial hair. Hormonal imbalances caused by certain medical conditions can affect facial hair growth.


In conclusion, the science behind facial hair growth is complex and influenced by various factors, including hair thickness, skin color, and hormones. While laser hair removal is still an effective treatment for both body and facial hair, it may work more slowly on the face due to these factors. However, individual characteristics can also play a role in the effectiveness of the treatment. If you are considering laser hair removal, it is important to consult with a qualified professional to determine the best course of action for your specific needs.
