Indian

Indian hair is incredibly diverse, largely due to the vast ethnic, linguistic, and cultural diversity found across the subcontinent. Most Indians typically have dark, straight to wavy hair, with a thick texture. In the northern parts of India, people often have hair that is straight or slightly wavy, while in the southern regions, especially among the Dravidian populations, the hair may appear coarser and curlier. Hair color is mostly black or dark brown, and the quality of hair is often thick and dense. The climate and lifestyle can also influence hair health, with many Indians using traditional oils like coconut oil to nourish and protect the hair.

Brazilian

Brazilian hair, particularly among its African and Indigenous mixed populations, is mostly characterized by thick, curly to coiled textures. Brazil's  diverse ethnic composition means there is a variety of hair types, including straight, wavy, and curly textures. Those of African descent in Brazil tend to have tightly coiled hair, while those with European and Indigenous roots may have straight or wavy hair. Brazilian hair is often thick and dense, but the use of chemical treatments such as relaxers and straighteners is common for those desiring straight hair. Dark brown to black are the most common hair colors.

Peruvian

Peruvian hair tends to be straight and thick, with a dense texture. People of indigenous descent from the Andean regions typically have straight hair, which is dark brown or black in color. However, there are variations in texture and color depending on regional influences, with some individuals of mixed descent having wavy or slightly curly hair. The environmental factors of the high-altitude regions in Peru also contribute to the strong and resilient nature of the hair, which has adapted over generations to the harsh climate.

Himalayan

Himalayan hair, particularly among the indigenous populations living in regions such as Nepal, Tibet, and parts of Northern India, is generally straight and thick. The hair is often black or dark brown, with a healthy sheen, reflecting the clear, cold mountain air and the high-altitude environment. In some cases, hair may appear slightly wavy or coarse, especially among people of Tibetan descent. The hair texture has evolved to withstand the harsh conditions of the Himalayan mountains, where the cold climate demands resilience.

Russian 

Russian hair is typically straight and thick, with a dense texture. People of Russian descent generally have hair that ranges from light blonde to dark brown, and some individuals from northern regions may even have very light or platinum blonde hair. The hair texture is usually fine to medium, and in colder regions, the hair often appears strong and healthy due to the cold, dry climate. In areas closer to Central Asia, some ethnic groups may have thicker, coarser hair with more wavy or curly textures.

Burmese

Burmese hair, from Myanmar (formerly Burma), is often dark, straight, and smooth. Most people of Burmese descent have thick, jet-black hair, and the texture tends to be straight or slightly wavy, with a healthy shine. The tropical climate influences the growth of the hair, often making it thick and lush. The Burmese also have a strong tradition of hair care, using natural oils such as coconut or sesame oil to maintain the health of their hair in the humid climate.

Vietnamese

Vietnamese hair is typically straight, thick, and black or dark brown. The texture is smooth and shiny, often growing long and strong due to the warm, tropical climate. The majority of Vietnamese people have straight hair, though in some northern mountainous regions, people of mixed descent might have wavier or even slightly curly hair. The strong, resilient nature of Vietnamese hair is partially attributed to the use of local natural oils and herbs for hair care, which have been passed down through generations.

Chinese

Chinese hair is generally straight, thick, and black, though some ethnic groups within China, such as those in the southern regions or the Tibetan population, may have hair that is wavy or coarser. Chinese hair tends to be very dense and is often smooth and sleek, a result of genetic adaptations to the environment. The hair care practices in China often involve using herbal remedies and oils to preserve its luster and strength, and it is common to see both men and women with long, flowing hair in traditional Chinese culture.

European

European hair characteristics can vary significantly, as Europe is home to a wide array of ethnic groups with different hair types. In general, European hair ranges from straight to wavy, and curly textures are also common, especially in Mediterranean regions. The hair color is equally varied, with blonde, brown, black, and red being the most common shades. Northern Europeans often have lighter hair, while southern Europeans tend to have darker hair, ranging from deep brown to black. European hair is typically medium to fine in texture and may require different care techniques based on the climate and lifestyle of specific regions.

Cambodian

Cambodian hair tends to be straight and thick, usually black or dark brown in color. The hair is often strong and resilient due to the tropical climate of Cambodia, where people generally have thick, healthy hair. While straight hair is most common, some Cambodians, particularly those of mixed ethnic backgrounds, may have slightly wavy hair. The hair is cared for with traditional oils and natural ingredients that help protect it from the humidity and heat of the region.

Filipino

Filipino hair is generally straight and thick, with a dense texture. The majority of Filipinos have black or dark brown hair, though some people of mixed ancestry may have wavy or even curly hair. The warm, tropical climate in the Philippines contributes to the growth of strong and healthy hair, and many Filipinos use natural oils such as coconut oil to maintain the condition of their hair. Hair care practices are deeply ingrained in Filipino culture, often passed down through generations.

Indonesian

Indonesian hair is predominantly straight and black or dark brown, with a thick and dense texture. People from the Indonesian archipelago, especially from the island of Java, typically have thick, straight hair, although those from more mixed or indigenous ethnic backgrounds may exhibit wavy or curly hair textures. The humid tropical climate of Indonesia plays a role in the thick, healthy appearance of the hair, and many locals use natural oils to nourish and protect their hair.

Malaysian

Malaysian hair, like that of many Southeast Asian populations, is typically straight, black, and thick, with a smooth texture. Due to the hot, humid climate of Malaysia, people generally have strong and resilient hair, and the use of natural oils such as coconut oil is common for maintenance. Malaysians of mixed heritage, especially those with Malay, Chinese, and Indian ancestry, may also have wavy or slightly curly hair, but straight hair remains the most prevalent.

Caucasian

Caucasian hair, often associated with people of European descent, comes in a variety of textures, ranging from straight to wavy and curly. It is typically fine to medium in texture, though some individuals may have coarse hair. The hair color can vary widely, with shades of blonde, brown, black, and red being the most common. Caucasians, particularly those from northern Europe, are more likely to have lighter-colored hair, whereas those from southern Europe may have darker hair. The texture and color of Caucasian hair vary greatly depending on the region, with many individuals opting for different styles and hair treatments.

Each of these ethnic groups presents unique hair characteristics shaped by a combination of genetic factors, geographic location, and cultural practices.
