Ethnic considerations in hair restoration surgeries have one practice in common that is grafting the human hair follicles. There are different ethnic groups divisions for human hair mainly three including white, African and Asian hair. These hair types belong to different groups due to their discernible characteristics like hair shape, composition, texture, diameter, mechanical properties and density. The texture and appearance of hair is determined by the hair follicle. The different ethnicities have different shapes of hair like the white people comprise ovoid, Asian people have round while African possess elliptical shape. Therefore, the hair follicle shape is responsible for the geometry, texture and appearance of hair. African hair has elliptical, Asians have circular while white possess intermediary geometry. When it comes to the hair composition, there is no distinction in groups observed in protein and chemical composition of hair. However, white hair has strong tensile strength as compared to African hair as it breaks easily. If the hair follicles of three ethnic groups are to be compared, then Asian people have metabolically active hair follicles as compared to African and whites. Hence, Asian hair grafts are more prone to dehydration yet they can be preserved for a long period of time. However, the patient seeking hair restoration or transplantation surgeries individually seek out the specialists as ethnic considerations are significant due to the influence of hair type on outcome or results.
Hair Density consideration in Ethnic hair transplant procedure
While ethnic considerations are done in hair restoration surgeries, one of the most important subjects to consider is evaluation of the characteristics of a patient’s hair. One of the characteristics to consider the most is its density in the site of donors. There are two factors checked relating density of hair like the hair concentration and size of single hair. A follicular unit per cm square is used to present the hair concentration. Out of these three ethnic groups, Asian people have the largest cross-sectional caliber while the hair density is intermediate in white people and lowest when it comes to African community. This characteristic can be confusing for the new hair transplantation surgeons as African hair seems to have higher density due to curly appearance of hair. Ethnic considerations are significant for the hair restoration surgeries as many factors that collectively contribute to and influence the life of an individual belonging to the different ethnic group in multiple ways.
Biological & physical aspects in ethnic hair transplant surgery
Ethnic considerations are important as all three ethnicities that undergo hair restoration surgeries have different biological composition, physical features and culture that eventually have impact on hair and surgeries. Physical features include shape and size of body, tone and color of skin, color of hair and its various characteristics. Biology of ethnic groups includes genetic inheritance patterns and hormonal patterns while the cultural differences include choice of food, hair styling techniques that differ and clothing choice preferences. All these characteristics are to be considered by both patient and hair restoration surgeon before they go for the actual transplantation. The cultural, biological and physical characteristics affect the outcome of the hair transplant. A highly professional skilled transplantation surgical team is to be considered that is well aware of ethnic consideration processes and racial differences and has wide experience with different types of hair for the successful possible outcome of hair restoration surgeries.
Other common ethnic considerations that influence the hair restoration results are head shape, hair characteristics, hair density, skin thickness and cultural preferences. Head shape includes both long and round shape as it requires different procedures for the hair transplantation or precisely its placement. The characteristics of hair that influence the surgeries are hair caliber, color of air, shape of hair (wavy, straight, and curly). The density of hair, for instance, difference in hair number per square centimeter of scalp also influences the outcome. Skin thickness of these three different ethnic groups is to be considered along with other genetic features of skin that affect the process of placement of transplanted hair. Cultural preferences also influence hair restoration surgeries as different ethnic groups find different types of baldness or different types of hairlines to be acceptable. It is significant to plan and advise clients before undergoing any surgery and make them aware of the risks that may occur regardless of the ethnic groups. Different ethnicities considering transplantation must know about keloid scar risk that occurs in rare cases. This rare complication is raised scar and might be the result of shock loss injury or after the skin is healed, being more common in dark skin toned people. Not only ethnic considerations are important but gender is also considered when patients undergo hair restoration surgeries.
Ethnic hair restoration techniques are sometimes exclusive to the type of hair as some ethnic groups require more care and special treatment as they have sensitive hair or less density. Asian people generally have dark and straight hair as compared to other ethnic groups. Although, they have dense hair mostly yet the coarseness of hair gives their hair a fuller look. This uniqueness of Asian hair requires exactly precise and careful follicular placement of transplanted hair. Asian males usually prefer a straight hairline that is angled at 90 degrees at temple regions. African hair is curly that is advantageous when it comes to transplantation surgeries as its curliness and texture improves the coverage to a larger area of the scalp from where the hair is removed and is to be transplanted as the follicular units density of African hair is low. The combination of advanced novel hair restoration surgeries along with the highly skilled and experienced aesthetic surgeons is effective to solve the issues like hairline gap and baldness in African people. The uniqueness of hair structure and follicles are basically the reasons why an experienced surgeon is required as he might be well aware of all the techniques and will opt for the specialized approach for different ethnic groups depending upon the hair texture and quality. FUE (follicular unit extraction) and FUT(follicular unit transplantation) surgeries are considered relying upon ethnic consideration but they both typically give good results and hair growth and hair seem to appear natural as well.
