What Causes Hair Loss

Hair loss can feel sudden and confusing, but it almost always has an underlying cause. Hair thinning, shedding, and balding affect men and women of any age—and identifying the "why" is the first step to lasting results. At EXO HAIR MD in Scottsdale, we evaluate the root causes of your hair loss so your treatment plan targets the real problem, not just the symptoms.

Common Causes of Hair Loss

Hair loss is rarely caused by a single factor. Genetics, hormones, health changes, and everyday stressors can all play a role, and often several of them overlap. These are some of the most common contributors we see in men and women:

• Rapid weight loss, including changes from GLP-1 medications
• Nutritional and vitamin deficiencies
• Genetics and hereditary thinning
• Hormone imbalance, such as high DHT or thyroid dysfunction
• Medical conditions and certain medications
• Recent illness or radiation exposure
• Tension from hair extensions or tight styling
• Covid or post-vaccine shedding
• Aging and metabolic changes
• Chronic stress and lack of sleep
• Pregnancy, childbirth, and postpartum changes
• Harsh hair products and daily environmental exposure

Hair Thinning, Shedding, and Balding

Many people notice increased shedding in the shower or on their pillow long before they see visible thinning. Others watch a part widen, a hairline recede, or a crown thin out over months. These are all signals that your follicles are under stress. The earlier we evaluate what's happening, the more options you typically have to protect and revive your existing hair.

Why a Professional Evaluation Matters

Because hair loss has so many possible causes, guessing at a solution often wastes time and money. Our evaluation looks at your history, patterns of loss, and contributing factors to determine whether regenerative exosome therapy is a good fit. This holistic approach helps us address the root causes of your hair loss for more natural, lasting results.

Is Treatment Suitable for Everyone?

Exosome therapy is generally safe and effective for most people with hair thinning, shedding, or loss. It may not be suitable for certain conditions, including cicatricial (scarring) alopecia, central centrifugal cicatricial alopecia, lichen planopilaris, dissecting cellulitis, advanced traction alopecia, or advanced androgenetic alopecia. Individuals who are pregnant or breastfeeding may be advised to postpone treatment. A consultation and evaluation are always required first.
