CHAPTER 1: ORIENTATION TO HAIR CARE
Damaged hair often results from hair care practices causing stress or harmful attacks on the hair strand or parts of the hair root. Therefore, knowledge of trichology is essential for repairing damaged hair. A comprehensive understanding of hair, its structure, chemical composition, and the many ways hair can be damaged is a significant advantage for hair care professionals within the beauty industry. understand, recommend, and use high-quality products that are formulated to treat and protect hair. Professional grooming also ensures clients are serviced with the latest hairstyle trends and products. Medical-related concerns about hair care are issues noticeable within hair analysis where hair abnormalities may be found that can be symptoms of health problems, such as hair loss and scalp disorders. Changes in the hair shaft’s structure and form may occur through clinical and morphological processes (Giacomari & Ferrando, 2022), meaning hair may become damaged due to medical concerns and physiological processes, such as pregnancy and natural occurrences within hair growth. Cleveland Clinic (2024) reported tissue damage as a significant medical concern in hair care issues, which often occurs from medical treatments involving radiotherapy and chemotherapy that threaten the healthfulness of the hair root. During these medicinal treatments, severe damage to the hair follicle occurs, causing induced alopecia. According to Giacomari and Ferrando (2022), microscopic analysis is a medical approach toward providing expert diagnosis of complex syndromes and isolated hair and scalp irregularities. Williams (2022) shared aspects of healthy hair relating to surface properties, such as the strength and integrity of the hair perceived by the condition of the hair strand’s outer parts. Healthy hair strands are free of hair disorders, have robust manageability, support maximum hair volume, and promote lengthiness in hair growth. Knight (2023) supported prior referencing, noting that hair conditions result from hair care choices, dietary habits, and individual overall lifestyles. Damaged hair noticeable among the hair shaft consists of weakness and signs of harm and breakage in the cuticle layer. Therefore, maintaining healthy hair and repairing damaged hair requires competency in all elements of hair science.
Hair care is the universal term for personal hygiene habits involving scalp health and grooming practices. Well- groomed hair is essential for making good impressions. Clean, shiny, and healthy hair represents wise hair care decisions and regular hygienic practices, symbolizing self- confidence and a positive attitude toward cleanliness. Hair care perspectives Hair care is significant in personal care, professional grooming, and medically related concerns. Personal hair care results from individual knowledge, attitude, and hair care practices, often called KAP. Knowledge of hair care is significant in one’s attitude toward hair care needs, which determines individual hair care practices. Hair care practices represent one’s necessity to express unique personalities and desired appearances through hair adornment. For many people, having healthy hair is crucial to their lives and lifestyles. Research by Fernandes et al. (2023) reported that having healthy hair improves self-esteem and psychological and emotional health. Professional grooming services include opportunities for expert advice and guidance on services and products for styling and maintaining the healthfulness of hair. McDonalds (2023) shared that the benefits of professional styling and haircuts include trained stylists who process the experience and knowledge to analyze facial features, skin types, lifestyles, and hair textures before recommending hair services suitable or necessary for clients. After a thorough consultation, professional stylists can tailor the hair service to the client’s needs. Hair professionals are trained to Damaged hair Damaged hair is hair that no longer possesses the looks and characteristics of healthy hair. Healthy hair results from lustrous skin, a nutritious diet, and reflective grooming practices. There are several signs regarding hair’s healthfulness. Nine important attributes provide evidence of strong and healthy hair (Barrie, 2022): 1. Naturally shiny hair. 2. Good elasticity.
3. A smooth texture. 4. Minimal breakage. 5. Normal shedding. 6. Scalp free of dandruff. 7. Water-repellant hair. 8. Body and movement. 9. Withstands humidity.
CHAPTER 2: THE EVOLUTION OF HUMAN HAIR
the principal functions of the skin to protect body organs, defend against diseases, and act as a barrier against harmful environmental elements. Both references note that hair supports the skin in safeguarding the body by providing a defensive shield from sun rays, supplying warmth, and acting as a protective buffer for the head and scalp. Research and scientific theories suggest that the look of modern-day humans, relating to their hair, is the result of Homo sapiens evolving from their primitive relatives with ape-like features (Kowalczyk et al., 2022). According to evolutionary beliefs, the human body has transformed from having large strands of hair all over the body to being mostly covered with smaller, less visible hair strands, known as vellus hair. Years of evolution changed human hair characteristics, leaving the presence of large strands of hair, known as primary hair, only remaining on the scalp, armpits, and pubic area (Timperely, 2023; Milady, 2023).
The prior content presented information about the hair care industry and how the different perspectives on hair care can significantly influence hair care practices, with a seeming focus on only the hair. Yet, hair care entails working with people and understanding human behavior, various cultures, and viewpoints toward hair. As Fernandes et al. (2023) noted, healthy hair helps with individual psychological and emotional health. According to Fritscher (2023), knowledge of the evolution of human hair can support the understanding of present-day individuals to live healthier lives within their environments and also help to develop a thorough understanding of the scientific factors that catalyzed extreme hair change in humans. Milady (2023) described the hair as a production of the skin—a threadlike, horny outgrowth of keratin projecting from the skin’s epidermis. Fernandes (2023) and Milady (2023) described the purpose of hair as coinciding with
