Is Japanese hair thick?


Japanese hair is often associated with being thick and difficult to manage. In this article, we will explore whether this is a fact or a myth.

Hair Structure and Thickness

The thickness of hair is determined by the number and size of hair follicles on the scalp. Japanese hair typically has a round cross-section, which makes it appear thicker than other hair types. However, the actual diameter of each strand is not necessarily thicker than other races.

Genetics Play a Role

Hair thickness is determined by genetics, meaning that if your family has thicker hair, chances are you will too. In Japan, there are several ethnic groups, including the Ainu people who have thicker and curlier hair than the average Japanese person.

Hair Care Products

Many Japanese hair care products are designed to volumize and add thickness to the hair. These products contain ingredients such as collagen and hyaluronic acid to plump up the hair shaft.

Styling Techniques

Japanese women often use hot rollers or curling irons to add volume to their hair. Backcombing or teasing the hair can also create the illusion of thickness.

Environmental Factors

The environment can have an effect on hair thickness. Exposure to harsh elements such as sun, wind, and pollution can damage the hair, making it appear thinner.

Diet and Nutrition

A healthy diet rich in vitamins and minerals can promote healthy hair growth. Foods such as salmon, eggs, and leafy greens contain nutrients that are essential for healthy hair.

Hormonal Changes

Hormonal changes such as pregnancy or menopause can affect the thickness of hair. During pregnancy, many women experience thicker and fuller hair due to hormonal changes.

Hair Loss

Hair loss can affect the appearance of hair thickness. Conditions such as alopecia or male pattern baldness can cause hair to thin, making it appear less thick.

Overall Hair Health

The overall health of the hair can also affect its thickness. Regular haircuts, avoiding heat damage, and using gentle hair care products can promote healthy hair growth and maintain thickness.

Cultural Perceptions

In Japanese culture, thick hair is often associated with youthfulness and beauty. Therefore, many people strive to achieve thicker looking hair through various methods.


In conclusion, while Japanese hair may appear thick due to its cross-sectional shape and cultural perceptions, individual hair thickness is determined by genetics, environmental factors, diet, and overall hair health. With proper care and attention, anyone can maintain healthy and voluminous looking hair.

Hair Texture

Apart from thickness, hair texture also plays a significant role in how easy or difficult it is to manage. Japanese hair is known for its straight and silky texture, which makes it easier to style and manage. However, this can also make it difficult to create volume and hold curls.


Japanese hairstyles often incorporate layers and blunt cuts to create the illusion of thickness and volume. Bob haircuts and layered hairstyles are popular choices among Japanese women, as they can add movement and dimension to the hair.

Hair Color

Hair color can also affect the appearance of hair thickness. Lighter hair colors, such as blonde or light brown, can make the hair appear finer and thinner, while darker colors can create the illusion of thickness.

Hair Extensions

Another option for achieving thicker-looking hair is using hair extensions. Japanese women often use clip-in extensions or weaves to add length and volume to their hair.

Cultural Influences

In Japan, beauty standards place a high value on youthful and feminine qualities, which includes having thick and voluminous hair. This cultural influence may contribute to the perception that Japanese hair is naturally thick and difficult to manage.


In summary, while Japanese hair may appear thick due to its cross-sectional shape and cultural influences, the actual thickness of each strand is determined by genetics, environmental factors, diet, and overall hair health. However, with proper care and styling techniques, anyone can achieve healthy and voluminous-looking hair regardless of their hair type or ethnicity.
