What Causes Alopecia? Exploring Autoimmune and Genetic Factors

Hair loss can catch you off guard, whether it’s sudden shedding, thinning around the temples, or patches you didn’t notice before. At Hollywood Dermatology, we see it every day and help patients from Hollywood to Doral, Florida, get answers. One of the biggest questions our board-certified doctors hear is: What causes alopecia?

The answer isn’t always straightforward. In many cases, it’s linked to your immune system, your family history, or both. Understanding what’s behind the hair loss helps us build a treatment plan that works.

Genetics and Hair Loss

One of the most common causes of alopecia is hereditary hair thinning. Known medically as androgenetic alopecia, this type of hair loss often runs in families. You might notice a gradual thinning at the crown or a receding hairline, especially as you age. 

While this type of hair loss can affect both men and women, the pattern and pace of hair loss may differ. It isn’t caused by poor hair care or products. It’s largely tied to your genetic makeup.

Autoimmune Triggers of Alopecia

In other cases, alopecia is related to your immune system. Alopecia areata is an autoimmune condition where the body mistakenly attacks hair follicles, leading to sudden hair loss in small, round patches. This type of alopecia can affect the scalp, eyebrows, or even eyelashes. 

Other autoimmune conditions, such as lupus or thyroid disease, may also contribute to hair thinning or shedding. These conditions can interrupt the normal hair growth cycle or cause inflammation that affects follicle health. 

Treatments Available in South Florida

Hollywood Dermatology offers advanced treatments like HairRevive Boost, a non-surgical injection therapy that uses your body’s own healing properties to restore hair growth. This treatment can potentially stimulate dormant follicles and reduce inflammation on the scalp.

We also offer Nutrafol, a physician-formulated supplement that supports hair health from within. There are options for men and women, including formulas for those experiencing hormonal changes.
