Hair Hair on the head is called terminal hair 65 – 95% of it is protein. Other components include water, fats (lipids), minerals, and pigment The complex shape of proteins held together by chemical bonds allows hair to be rigid and flexible The shaft of a single hair has three layers. The cuticle, cortex which contains keratin, and the central core of the hair is the medulla Hair grows from a tiny pouch below the skin’s surface called a follicle The actively growing part of the hair shaft is the hair bulb. As soon as hair cells are manufactured, they harden and die, forming the hair shaft.

Hair Growth and Loss Hair growth and replacement occur in 3 stages: Anagen – active growth stage, lasting from 2-6 years. Catagen – lasting about 2 weeks, the lower segment of the hair follicle breaks down. A “club hair” separates from the papilla and falls out Telogen – the follicle rests, lasting several weeks or months About 80 to 90% of the hairs on the head are in anagen stage, 3 to 4 percent are in catagen, and the remainder are in telogen Humans lose 50-100 scalp hairs per day which is normal Alopecia, or noticeable hair loss, occurs in nearly 1/3 of women and 2/3 of men. Women typically notice a general thinning of the hair, while men usually experience baldness The cause is not the cessation of hair growth. Instead, follicles gradually shrink and become less active, producing shorter, finer hairs Heredity, hormones, and aging cause the change in follicles.

Hair Loss Treatment Since ancient times, people have sought to prevent or reverse the balding process No drug can reverse baldness in its later stages. However, minoxidil (trade name Rogaine) slows the rate of hair loss or promotes regrowth in about 25 percent of men and 20 percent of women It received the approval of the FDA in 1988 and became available without a prescription in 1996. Also, finasteride (trade name Propecia), was approved in 1997 for use in men only. Surgical alternatives are available for those bothered by baldness Hair transplants - surgeons remove parts of the scalp and transfer them to the top, reducing the total area of baldness. Another alternative is flap surgery - A flap of hair-bearing scalp is turned to cover the spot where bald scalp has been removed

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
