There are several types of hair loss. Trichotillomania, a compulsive behaviour that leads to hair loss from hair being routinely pulled or tugged on, is one. Trichotillomania usually begins around puberty and continues throughout adulthood. Hair loss may be permanent if the individual continues to pull the hair.
Lichen planopilaris, another type of hair loss, is caused by a skin infection called lichen planus. Inflammation of the hair follicles, which look similar to acne, leads to patchy baldness. Early cases of folliculitis may not be visible, but they may be red, flaky, or containing small bumps. While lichen planopilaris is rare, a physician can prescribe medication to cure the condition.
Androgenetic alopecia is the most common type of hair loss. Millions of people worldwide suffer from it. Both men and women can experience androgenic alopecia. Male pattern baldness is more common and may start at any age, and can result from the interaction of three factors. Female pattern baldness, on the other hand, occurs over the top of the scalp and is sparse in the front.
An increasingly popular treatment for thinning hair is scalp micropigmentation. To find out more about this process, consider Scalp Micropigmentation Birmingham from His Hair Clinic, a provider of Scalp Micropigmentation Birmingham procedures.
Inflammation of the scalp causes bald spots or patches of hair loss. Scalp ringworm, or tinea capitis, is another common form of hair loss. Inflammation destroys hair follicles and leaves scar tissue behind. This scarring prevents hair from regrowing. The affected areas may be swollen and itchy.
Telogen effluvium, on the other hand, does not lead to baldness. Instead, the affected individual loses between 300 and 500 hairs per day and their hair may appear thin. It is triggered by a variety of factors, including thyroid imbalance, childbirth, surgery and even shock. The condition has a usual onset of around 3 months after an event. Thankfully, this condition is reversible although hair might take around 6 months to regrow. In addition to hormonal changes, medications, and iron deficiency can lead to this type of hair loss.
Hair loss can occur anywhere on the body. While hair loss can occur anywhere on the body, it affects the scalp the most. On average, each scalp has around 100,000 hairs that go through cycles of growth, rest, and fallout. The hairs regenerate during their fallout and regeneration phases. Fortunately, most types of hair loss can be alleviated with treatment.
