Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably keratin.
Hair is a very diverse and complex subject. There are many different types of hair, such as straight, wavy, curly, kinky, and coily. Each type of hair has its own unique characteristics and requires different care and styling techniques.
Hair care is an important part of maintaining healthy hair. Proper hair care includes regular shampooing and conditioning, as well as using the right products for your hair type. It is also important to protect your hair from the sun and other environmental factors.
Hair loss is a common problem that affects both men and women. It can be caused by a variety of factors, including genetics, hormones, stress, and certain medical conditions. Treatment options for hair loss include medications, surgery, and lifestyle changes.
