Understanding the Causes, Diagnosis, and Treatments for Hair Loss

Hair Loss is Extremely Common Among Both Men and Women

Hair loss is an extremely common issue affecting close to 100 million Americans. It can occur in both men and women due to a variety of factors including genetics, hormones, certain medications, and underlying health conditions. Male pattern baldness linked to dihydrotestosterone (DHT) accounts for most hair loss in men, while the causes tend to be more complex in women. Regardless of gender, it is important to understand that hair loss can begin early in life but may not become noticeable until significant thinning has occurred.

Monitoring Changes in Hair Density and Quality

Both men and women will experience some changes in hair density and quality over their lifetime. Pregnancy, for example, often leads to increased thickness during gestation followed by shedding in the months after giving birth. Normal hormonal fluctuations during peri-menopause and menopause can also impact hair growth cycles in women.

While some hair loss is normal, patients tend to seek medical advice when they notice increased shedding over a prolonged timeframe or visible thinning. At this stage, specialized diagnostic testing can determine if hair follicles are beginning to miniaturize. If left unchecked, these miniaturized follicles will eventually stop producing visible hair.

Seeking a Proper Diagnosis is the Critical First Step

Patients reporting hair shedding or thinning should have a series of diagnostic tests performed to accurately determine the underlying cause. Trichometry uses highly sensitive instruments to compare hair density and diameter across different regions of the scalp. By comparing presumed unaffected areas like the back of the head to visibly thinner areas, technicians can detect early miniaturization.

Testing may also assess hair tensile strength along with scalp health indicators including pH, inflammation markers, sebum production, etc. The goal is to differentiate between temporary shedding that may self-resolve versus progressive miniaturization requiring intervention to prevent permanent baldness.

Many Doctors Lack Proper Training to Diagnose Hair Loss

Unfortunately, many primary care doctors and even dermatologists lack specialized training in hair loss diagnosis and treatment. Consequently, patient complaints are often dismissed or attributed to normal aging. This can lead to a delay in starting treatments until after follicles sustain irreparable damage.

Patients getting the “run around” without actionable diagnosis or treatment advice are encouraged to seek out hair restoration specialists. These experts have advanced equipment, conduct detailed examinations of the hair and scalp, and can recommend customized treatment regimens based on the specific type of hair loss identified.

Using Medications to Target Hormonal Causes of Hair Loss

In cases of androgenetic alopecia linked to DHT sensitivity, physicians may prescribe oral or topical medications designed to block conversion of testosterone. The drug finasteride prevents formation of DHT to effectively treat male pattern baldness in over 90% of men with a low risk of sexual side effects.

Women have more complex hormonal drivers of hair loss excluding them from using finasteride or similar anti-androgens during childbearing years. However, doctors may still prescribe these drugs for androgenetic alopecia arising due to menopause. Younger women tend to respond better to alternative drug and non-drug treatment modalities.

Topical Treatments to Stimulate Follicles

The FDA has approved two topical medications capable of reviving dormant follicles to stimulate regrowth – minoxidil and low-level laser therapy. Minoxidil opens potassium channels allowing better nutrient flow to starving follicles, while laser photobiomodulation boosts cellular metabolism.

Both help transition hairs back from vellus (fine, transparent) to terminal status. They work best when initiated before complete miniaturization has occurred. Although less effective than anti-androgens for male pattern baldness, they still represent the best option for most women seeking pharmaceutical treatment.

Leveraging Non-Drug Therapies

For patients hesitant to take medications or apply chemicals long-term, emerging non-drug options like PRP injections may offer similar regrowth potential without the risk of side effects. Treatment involves using the patient’s own platelet-rich plasma activated with growth factors to stimulate follicles.

Oral supplements like biotin, zinc, iron, and vitamin D can also support hair health – especially when hair loss arises due to nutritional deficiency states. However, the utility of supplements to treat pure androgenetic alopecia remains questionable according to available clinical evidence.

Lastly, customized hair and scalp care regimens help reduce excess shedding and breakage by addressing the damaging effects of overstyling. However, no special shampoo or conditioner alone can substitute for medical therapy in most cases of progressive genetic hair loss.

Restoring Lost Hair with Hair Transplantation

For patients with extensive Stage IV male pattern baldness or advanced thinning in women, medications and laser therapy may help preserve remaining hair but cannot restore what has already been lost. This is where hair transplantation provides the only option capable of reestablishing the original hair line using one’s own permanent, living follicles.

Modern transplant techniques involving extraction and placement of individual hair follicles can produce extremely natural results even in cases requiring large numbers of grafts. Over 20,000 transplants are now performed annually using proven, minimally-invasive methods that facilitate rapid healing with minimal scarring.

Combining hair transplantation capable of recreating lost volume with medications or laser to protect against further thinning, provides full disease control – essentially resetting the clock on hair loss for both men and women suffering from advanced genetic alopecia.
