The Science of Black Hair is certainly a treasure, not only for my customers but for me as an African American woman in general who is interested in caring for my own hair. I refer to it, and encourage my clients who wish to know more about this much fussed-over appendage to read it as well. Fellow hair masters and stylists at salons worldwide, give YOUR clients a healthy hair advantage by including this book in your salon. Audrey, many thanks for bringing this valuable information together in such a timeless volume at such a critical time for black hair care. Thank you for helping us all to understand, The Science of Black Hair.
And yet, with all of the reading and writing I have done on the topic of black hair over the years, I have not come across a more well-researched, exhaustive and comprehensive book as The Science of Black Hair.
Understanding the science of our hair helps us truly understand our hair. When you know what frizz really is, you know how to prevent it. When you understand what protein does for the hair, you understand how to use it and when. When you understand what a blow dryer does to the hair, you have a reason to use it sparingly.
I stumbled across my first online hair community in the summer of 2004, and by this point, my frustration with my hair was at an all-time high. The hair-care sites were just what I needed for motivation and support. They were full of information on healthy black hair care, and whole communities of black women were supporting each other day in and day out, challenging one another to grow their hair out natural and relaxed to greater lengths. It was beautiful and encouraging, and without those many ladies I would not be here today. Those sisters inspired me to put my thoughts on hair care together into a book with the hope that this knowledge will continue to be shared in our community.
My own misunderstanding of textured hair cost me dearly over the years. I am fortunate that I have been able to reexamine many of my earlier beliefs about my own head of hair and come to terms with them. My view of textured hair as a rough, indestructible force led me to snatch combs and brushes through it at every turn. I thought my hair was tough and had to be manhandled into place. I thought it could take anything. I was abusing my hair and expecting it to just continue to thrive. But no more!
Hair breakage is the number one enemy of healthy, vibrant black hair. Until we understand the causes of breakage and take steps to control it, we will be unable to add visible length to our hair over time. This book presents a proven method for improving black hair health. It reveals a strategy for identifying and correcting common hair breakage issues, mostly using products you already have at home.
Unfortunately, hair-care misinformation runs rampant in the black hair community. Countless individuals capitalize on our lack of basic knowledge about healthy hair. Hair companies have unleashed many products over the years to satisfy this overwhelming demand for healthier, longer, stronger black hair. Some of these hair products are true
You have African textured hair for the same reason Africans have Caucasian textured hair. Genetics. Obviously someone in your family, known or unknown by you was African. That is the only way for that to happen.
Kinky hair, also known as afro-textured hair, is a human hair texture prevalent in the indigenous populations of many regions with hot climates, mainly sub-Saharan Africa, Melanesia, and Australia. Each strand of this hair type grows in a tiny, angle-like helix shape. The overall effect is such that, contrasted with straight hair, wavy hair, or curly hair, kinky hair appears denser.[1]
Different genetic groups have observable differences in the structure, density, and growth rate of hair. With regard to structure, all human hair has the same basic chemical composition in terms of keratin protein content. Franbourg et al. have found that black hair may differ in the distribution of lipids throughout the hair shaft.[5] Classical kinky hair has been found to be not as densely concentrated on the scalp as other follicle types. Specifically, the average density of kinky hair was found to be approximately 190 hairs per square centimeter. This was significantly lower than that of European hair, which, on average, has approximately 227 hairs per square centimeter.[1]
Loussourarn found that kinky hair grows at an average rate of approximately 256 micrometers per day, whereas European-textured straight hair grows at approximately 396 micrometers per day.[1][6] In addition, due to a phenomenon called 'shrinkage', kinky hair that is a given length when stretched straight can appear much shorter when allowed to naturally coil.[7] Shrinkage is most evident when kinky hair is (or has recently been) wet. The more coiled the hair texture, the higher its shrinkage.
The shape of the hair follicle determines the hair's curliness. An individual hair's shape is never completely circular. The cross-section of a hair is an ellipse, which can tend towards a circle or be distinctly flattened. East Asiatic heads of straight hair are formed from almost-round hair follicles producing straight hair, and European hair follicle forms oval shapes which produce wavy hair. Kinky hair has a flattened cross-section and is finer, and its ringlets can form tight circles with diameters of only a few millimeters. In humans worldwide, East Asian-textured hair is the most common, whereas kinky hair is the least common. This is because the former hair texture is typical of the large populations inhabiting the Far East as well as the indigenous peoples of the Americas.[8]
In many traditional cultures, communal grooming was a social event when women socialized and strengthened bonds with their families.[13][14] Historically, hair braiding was not a paid trade.[citation needed] When men from the Wolof tribe (in modern Senegal and The Gambia) went to war they wore a braided style. A woman in mourning would either not "do" her hair or adopt a subdued style.[15] Since the African diaspora, in the 20th and 21st centuries it has developed into a multimillion-dollar business in such regions as the United States, South Africa and among black African migrants to western Europe.[citation needed] An individual's hair groomer was usually someone whom they knew closely.[citation needed] Sessions can include shampooing, oiling, combing, braiding and twisting, plus adding accessories.
For shampooing, black soap was widely used in nations in West and Central Africa.[16] Additionally, palm oil and palm kernel oil were popularly used for oiling the scalp.[citation needed] Shea butter has traditionally been used to moisturize and dress the hair.[citation needed]
Because of the then-prevalent notion that straight wavy or curly hair (which, unlike kinky hair, is common in people of European origin) was more acceptable than kinky hair, many black people began exploring solutions for straightening, or relaxing, their tresses. One post-slavery method was a mixture of lye, egg and potato, which burned the scalp upon contact.[22]
Hair is as relevant as skin color when it comes to racial discrimination. A 2014 New York Times article, for instance, makes a case for military regulation in the United States to be reconsidered as it did not take black service women into account when describing acceptable hair styles for military personal. US military revised its regulations on cornrows and dreadlocks in 2017, which was previously banned.
Afro-textured hair is stereotyped and stigmatized around the world. Even in places where there are protections against race-based hair discrimination, Black women bear the brunt of the burden when it comes to hair bias.
In the late 1960s, American fashion changed, idealizing more natural-appearing hair styles. Hair products aimed at African American consumers emphasized kinkier-textured hair and less-restrained hair styles. Hair products aimed at white Americans emphasized long, smooth, straight hair. After the 1960s, American hair fashions changed more quickly than they had in the past, and the increasing variety in hair care products reflected the American trend for greater experimentation with personal appearance.
Throughout the last several decades, styles have evolved from afros to relaxers to naturally defined curls and so have the chemistries. The heavy use of mineral oil and petrolatum that was once found in many classic black hair products in the 1970s-80s was eventually replaced by silicone ingredients, silicone elastomers and polymer science chemistries.
