Hair Loss Treatment FAQs

When should I see a dermatologist for hair loss?

It is normal to shed about 50–100 hairs per day. However, you should see a dermatologist if you notice:

• Excessive shedding (more than ~125 hairs per day)
• A widening part or thinning ponytail
• A receding hairline
• Bald or patchy areas
• Scalp symptoms such as itching, burning, or scaling

Hair loss can sometimes signal underlying medical conditions. Early diagnosis is critical because some types of hair loss can become permanent if not treated promptly.

What is the most effective treatment for hair loss?

The most effective treatment depends on the cause of hair loss, which is why diagnosis comes first.

Common treatments include:

• Topical or oral medications (such as minoxidil or finasteride)
• Anti-inflammatory treatments for scarring alopecia
• Procedures such as PRP or in-office therapies

There is no one-size-fits-all solution—targeting the underlying condition is what leads to the best outcomes.

Can hair loss be reversed?

It depends on the type of hair loss.

• Non-scarring alopecia (such as stress-related shedding or hormonal thinning) is often reversible with proper treatment.
• Scarring alopecia (such as CCCA or lichen planopilaris) permanently damages the hair follicle.

This is why early evaluation is so important—we aim to treat inflammation before permanent damage occurs.

What is Central Centrifugal Cicatricial Alopecia (CCCA)?

Central Centrifugal Cicatricial Alopecia (CCCA) is a form of scarring hair loss that primarily affects Black women. It usually begins at the crown of the scalp and spreads outward.

It is associated with:

• Genetics
• Inflammation
• Certain hairstyling practices

Because CCCA causes permanent follicle damage, early diagnosis and treatment are critical. Dr. Strachan specializes in diagnosing and managing this condition to help prevent progression.

Can hairstyles like braids or ponytails cause hair loss?

Yes. This is called traction alopecia, which occurs when repeated tension from tight hairstyles damages the hair follicles.

Common causes include:

• Tight braids or locs
• Weaves or extensions
• Tight ponytails or buns

If caught early, traction alopecia can be reversible. However, long-term tension can lead to permanent hair loss.

Do laser caps or red light therapy devices really work for hair loss?

Low-level laser therapy (LLLT) devices—such as HairMax, Capillus, and iRestore—may help stimulate hair growth in early androgenetic alopecia.

However:

• Results are typically modest
• Consistent, long-term use is required
• They are not effective for all types of hair loss, especially scarring alopecia

These devices may be helpful as part of a broader treatment plan, but they are not a substitute for medical care.

Are exosome treatments better than PRP for hair loss?

Exosome therapy is a newer, heavily marketed treatment that uses cell-derived signaling particles to influence hair follicles.

However:

• It is not well standardized
• It lacks strong clinical evidence compared to PRP
• It is not FDA-approved for hair loss

PRP has more supporting data, while exosomes are still considered experimental in many cases.

Is it safe to use Hims or Keeps for hair loss treatment?

Online platforms like Hims and Keeps provide access to medications such as minoxidil and finasteride.

While convenient, they:

• Do not provide a full scalp exam
• May miss underlying diagnoses
• Offer less personalized treatment

A board-certified dermatologist can determine the exact cause of hair loss and tailor treatment appropriately.

Do hair growth supplements like Nutrafol or Viviscal work?

Supplements like Nutrafol and Viviscal may support hair growth in certain situations, particularly if nutritional deficiencies are present.

However:

• They do not treat most underlying causes of hair loss
• They should not replace medical therapy
• Results are often modest and variable

They may be used as a supportive treatment, not a primary one.

Do I need a scalp biopsy for hair loss?

Not always—but in some cases, it is necessary.

A scalp biopsy may be recommended when:

• The diagnosis is unclear
• Scarring alopecia is suspected
• Hair loss is not responding to treatment

It involves taking a small sample of the scalp for microscopic evaluation and is considered the gold standard for diagnosing certain hair loss conditions.

Does insurance cover hair loss treatment?

Medical visits to diagnose hair loss are often covered by insurance, similar to other medical conditions.

However, treatments considered cosmetic—such as:

• PRP
• Laser treatments
• Hair transplants
• Devices like Alma TED

are typically not covered.

Coverage will be reviewed during your consultation.

Does frequent hair washing or “greasing” the scalp affect hair loss?

Scalp care plays an important role in hair health.

• Heavy oils or “grease” can contribute to buildup and worsen scalp conditions like dandruff or inflammation
• Washing too infrequently can lead to accumulation that interferes with healthy growth

A balanced, customized hair care routine based on your hair type and scalp condition is essential.

What is trichoscopy and why is it important for hair loss diagnosis?

Trichoscopy is a non-invasive method of examining the scalp and hair using a specialized magnifying device. It allows the dermatologist to closely evaluate:

• Hair shaft thickness and variation
• Signs of inflammation or scarring
• Follicular openings
• Patterns of hair loss

This helps distinguish between different types of alopecia—such as androgenetic alopecia, alopecia areata, and scarring alopecias—without the need for immediate biopsy in many cases.

Do I need blood work for hair loss?

In some cases, yes. Blood tests may be recommended to identify underlying medical causes of hair loss.

Common tests include:

• Iron levels (ferritin)
• Thyroid function (TSH)
• Vitamin D levels
• Hormonal evaluation (in certain patients)

Blood work is especially helpful when there is:

• Diffuse shedding
• Sudden hair loss
• Signs of a systemic condition

Not all patients need blood work, but it can be an important part of a complete evaluation.
