Thyroid Disease & Hair Loss
Rapid hair loss can be caused by a number of things, but one of the most common causes is thyroid disease. Normally, hair grows until it enters a resting period. A normal head of hair has about ten percent of the follicles resting.
Hair loss occurs with thyroid disease due to the transfer of your body's energy. When the body has important crisis work to perform, hair cells shut down to allow more energy in other areas. Therefore, more hairs may be put into resting and stop growing, resulting in loss.
The thyroid is a large gland located in the neck. It's job is to control how the body burns energy, formulates proteins, and reacts to hormones. The thyroid produces T4 and T3, with involve metabolism and cell growth. Occasionally, the thyroid can become overactive or under active, resulting in thyroid disease. There are three general types of hair loss.
Shedding occurs when hair is lost throughout the entire head. It is usually noticed as a thinning of the hair. Hair can be found accumulating in shower drains or brushes. There will be no bald patches. Male pattern baldness usually occurs in only men, but women can occasionally suffer from it as well. Male pattern baldness is exactly what it implies - the hair is loss in a specific pattern. It tends to begins at the temples and recede from there, and can also appear as a bald patch in the center of the top of the head. It's DHT, a sex hormone, causes the hair follicles to shrink until hair can no longer be produced. DHT appears in levels significant enough to close off follicles when it is the conversion product of testosterone. Thyroid disease may cause testosterone to convert to DHT faster. Hair loss can also develop as a series of patches, and this is commonly caused by fungal infection. Besides these things and thyroid disease, hair loss can also be caused by:
- Poor diet
- Nutritional deficiencies
- Hormone changes
Therefore, when experiencing rapid hair loss, it's important to see a professional and determine what exactly is causing the loss. If it is thyroid disease, beware! Some medications contain hair loss as an additional side effect. Treatments for hair loss itself can also be difficult. Hair replacement surgery involves transplanting working follicles to areas of the head where hair has stopped growing. This can be painful and time-consuming. Prescription drugs for balding often have negative side effects, including irritation of the scalp and sexual dysfunction. There are, however, some alternative options. Hair loss supplements, containing the natural components essential for healthy hair growth.
