Explaining Hair Loss Caused by Scalp Inflammation

Inflammation of the scalp may be one of th emost important cause of hair loss to address. It is associated with scalp fibrosis and reduced blood flow to the hair follicles: both of which are major hair killers.

Hair loss caused by scalp inflammation
Hair loss can be caused by a wide range of conditions, beginning with inflammatory skin diseases and inflammation in the hair follicles. The exact causes of auto-immune inflammation are not well known; also, it is not known why in most cases only certain areas of the scalp (patches) are affected.

What causes inflammation?

Inflammation is caused by abnormal levels of cytokines (cell-signaling proteins also known as “immunomodulating agents”), which are produced in excess by overactive immune cells. White blood cells and antibodies are part of our immune system and are produced by our body to fight against foreign objects (viruses, bacteria).

Why does inflammation cause hair loss?

In autoimmune conditions, your body’s immune system treats your own cells or organs as foreign objects and puts in place a mechanism to destroy them, which leads to inflammation – your body’s response to intruding microorganisms. A high body temperature is the most common sign of inflammation.
When it comes to hair loss, your body mistakenly treats hair follicles as ‘foreign objects’ and destroys them, resulting in alopecia. Moreover, inflammation interferes with the nourishment of your hair roots by damaging the scalp (e.g. burning sensation, itchy/red spots, flaking).

What causes scalp inflammation and how exactly does this happen?

Cicatricial alopecia is one of the rarest conditions causing scalp inflammation. Infectious folliculitis, discoid lupus erythematosus and lichen planopilaris are only a few examples of cicatricial alopecia.
In cicatricial alopecia, the stem cells and sebaceous glands at the upper part of the hair follicle are affected by inflammation, which eventually destroys the follicle and replaces it with scar tissue. Therefore, the damage is considered by many to be irreversible and hair will not grow back after the inflammation has been treated.
Autoimmune inflammation around the hair follicle, e.g. alopecia areata is also considered to be an autoimmune disease where hair roots are mistaken as foreign. White blood cells gather around them, leading to inflammation. This cuts off nutrient supply, causing follicles to become weak and eventually fall out.
However, unlike in cicatricial alopecia, hair will regrow if the autoimmune reaction is treated; therefore, there is a good chance for your hair to look better than ever if you receive treatment for alopecia areata.
Seborrheic eczema and psoriasis are inflammatory skin conditions that damage the scalp, causing red, dry, flaky patches which affect hair roots and the aspect of the hair shaft. Depending on the stage of the condition, it may be possible for hair to regenerate once the underlying causes have been treated.

What can you do to reduce inflammation in the scalp?

Always see your doctor before pursuing any form of treatment for scalp inflammation. Bear in mind that alopecia areata is generally a very unpredictable condition and some hair patches may regrow by themselves without treatment. However, your doctor may administer steroid injections to counteract the inflammatory effects of this type of condition. Topical steroids (hydrocortisone) and Minoxidil may bring real improvements, although there is no effective “cure” for scalp inflammation itself. Remember there is no harm in trying as long as a medical professional approves, and that every organism is unique and responds to treatment in its own way.
