- The hair follicle is a narrow tube in the skin where each hair grows, featuring a gland that produces oil to lubricate the hair and soften surrounding skin.
- Different hair types include dry hair, which appears dull due to insufficient oil production or improper care, and can be treated with conditioners and protein.
- Oily hair results from overactive glands producing excess oil, while soft hair is light and easily affected by wind.
- Coarse hair is thick and challenging to manage, whereas hair length varies due to genetics, diet, and care; long hair can be styled by plaiting.
- Artificial hair, such as wigs and extensions, can be integrated with natural hair for styling purposes.
Structure and function of the hair follicle
Each hair grows from a narrow tube in the skin called hair follicle. Each follicle has a tiny oil ground near its base. The gland produces an oil that lubricates the hair and softens the skin around it.
There are different hair types. These include:
a. Dry hair: this is dry, dull and unattractive. It can result from insufficient production of oil by the glands, poor food, illness or damaged to the hair as a result of improper care. Dry hair can be mosturised with leave-in conditioners and protein treatments.
b. Oily or greasy hair: this occurs when the glands are over-active and produce more oil than is needed.
c. Soft hair: this type is often light and can easily be blown about by the wind.
d. Tough or coarse hair: this is thick and could be difficult to comb or manage
e. Short hair: some people can inherit short hair while others have long hair. Some people however prefer to wear their hair short.
f. Long hair: some people have and wear long hair. This type of hair can also result from heredity, god food and proper care of the hair. Long hair can be kept tidy by plaiting and/or packing it.
g. Artificial hair: these are available as wigs and hair pieces commonly called "attachment" or "hair extensions". These can be plaited in with the natural hair.
