Hair Restoration & Hair Loss Treatment
Hair loss is one of the most common — and most treatable — concerns in dermatology. Our board-certified providers offer comprehensive evaluation and the latest medical therapies to help you restore and preserve your hair.
Schedule an AppointmentTypes of Hair Loss We Treat
Hair loss — medically called alopecia — has many different causes. The right treatment depends entirely on getting the diagnosis right. Our dermatologists are trained to identify which type you have and build a plan around it.
Androgenetic Alopecia (Pattern Hair Loss)
This is the most common cause of hair loss in both men and women. It's driven by a genetic sensitivity to a hormone called DHT. In men, it typically causes a receding hairline and crown thinning. In women, it usually appears as diffuse thinning along the top of the scalp, with the frontal hairline staying intact. Multiple effective treatments are available, and starting early gets the best results.
Alopecia Areata
Alopecia areata is an autoimmune condition. The immune system mistakenly attacks hair follicles, causing patchy or sudden hair loss. It can affect the scalp, eyebrows, eyelashes, and body hair. Severity varies — from a single small patch to complete loss of all scalp and body hair. Newer FDA-approved medications called JAK inhibitors have transformed outcomes for moderate-to-severe cases.
Telogen Effluvium
Telogen effluvium is a temporary form of diffuse shedding. It's often triggered by stress, illness, surgery, childbirth, crash dieting, or nutritional deficiencies. Hair typically sheds 2–4 months after the trigger. In most cases, shedding stops once the underlying cause is addressed. Full recovery can take 6–12 months.
Scarring Alopecias
Scarring alopecias are a group of less common conditions. They include lichen planopilaris, frontal fibrosing alopecia, discoid lupus, and central centrifugal cicatricial alopecia. In each, inflammation destroys hair follicles and replaces them with scar tissue. That damage is permanent — which is why early diagnosis and prompt treatment to stop progression are so important.
Traction Alopecia
Traction alopecia is caused by chronic tension on follicles from tight hairstyles — braids, weaves, ponytails, or extensions. Caught early, it's reversible with style changes. Long-standing traction can cause permanent damage. Our providers offer guidance on protective styling alongside any medical treatment needed.
Diagnostic Approach
Accurate diagnosis is the foundation of effective hair loss treatment. During your evaluation, our providers will:
- Take a thorough history including onset, pattern, family history, medications, diet, hormonal changes, and recent stressors
- Perform a detailed scalp and hair shaft examination
- Use dermoscopy — a handheld magnification tool — to assess follicle health, miniaturization, and scalp inflammation at high resolution
- Order targeted blood work as appropriate: thyroid function (TSH, T4), ferritin (iron stores), complete blood count, hormones (DHEA-S, testosterone, prolactin), vitamin D, and zinc
- Perform a scalp biopsy when the diagnosis is unclear or a scarring alopecia is suspected
Treatment Options
Androgenetic Alopecia
- Topical minoxidil (2% or 5%) — applied to the scalp daily to stimulate follicles and extend the growth phase
- Oral low-dose minoxidil — increasingly used for broader coverage or when topical application is impractical
- Finasteride (for men) — an oral DHT-blocking medication that slows loss and stimulates regrowth in many patients
- Spironolactone (for women) — an anti-androgen medication that reduces the hormonal driver of female pattern hair loss
- PRP (platelet-rich plasma) therapy — injections of concentrated growth factors to stimulate follicular activity
- Hair transplant referral — for patients who are appropriate surgical candidates seeking permanent restoration
Alopecia Areata
- Intralesional corticosteroid injections — the most common first-line treatment for patchy alopecia areata, injected directly into bald patches to suppress local inflammation
- Topical corticosteroids and immunosuppressants (tacrolimus, anthralin) for mild or pediatric cases
- Oral corticosteroids — short courses for rapidly progressing disease
- Baricitinib (Olumiant) — FDA-approved JAK1/2 inhibitor for adults with severe alopecia areata
- Ritlecitinib (Litfulo) — FDA-approved JAK3/TEC inhibitor for patients 12 and older with severe alopecia areata
- Minoxidil as adjunctive therapy to promote regrowth in recovering areas
Telogen Effluvium
- Identify and treat the underlying trigger: correct nutritional deficiencies (iron, vitamin D, zinc, protein), optimize thyroid function, address postpartum or stress-related causes
- Minoxidil to support faster regrowth during the recovery phase
- Patient education on realistic timelines and reassurance — most cases resolve within 6-12 months
PRP (Platelet-Rich Plasma) Therapy
PRP is an in-office treatment that uses your body's own growth factors to stimulate hair follicle activity. Here's how it works:
- A small blood sample is drawn from your arm — similar to a routine lab draw
- The blood is placed in a centrifuge, which spins at high speed to separate and concentrate the platelet-rich plasma
- The concentrated PRP — rich in growth factors like PDGF, VEGF, and IGF-1 — is injected across the treatment area of the scalp
- Multiple sessions (typically 3 initial treatments spaced 4-6 weeks apart) are recommended, followed by maintenance injections every 4-6 months
- Most patients tolerate the procedure well; a topical numbing cream can be applied beforehand for comfort
Why Early Treatment Matters
Hair follicles are living structures. Over time, inflammation, DHT, or chronic tension can damage them permanently. In scarring alopecias, scar tissue replaces healthy follicles — that loss is irreversible. In androgenetic alopecia, follicles gradually shrink until they can no longer grow a visible hair.
Starting treatment early — while follicles are still active — consistently produces better outcomes. Even if you're thinning but haven't lost everything, acting now can preserve more. If you've noticed changes in density, texture, or shedding, don't wait. The sooner you're evaluated, the better your chances of keeping what you have.

Frequently Asked Questions
Is hair loss reversible?
It depends on the cause. Non-scarring forms of hair loss — such as androgenetic alopecia, alopecia areata, and telogen effluvium — are often treatable, and many patients see meaningful regrowth with appropriate therapy. However, scarring alopecias permanently destroy hair follicles, which is why early diagnosis and treatment are so important. The sooner treatment begins, the better the chances of preserving and restoring hair.
What is PRP therapy and how does it work?
Platelet-rich plasma (PRP) therapy involves drawing a small amount of your blood, processing it in a centrifuge to concentrate the growth factors, and injecting that concentrated plasma into the scalp. The growth factors in PRP stimulate dormant follicles, improve blood supply to the scalp, and promote the active phase of hair growth. PRP is available in-office at Dermatology of Seattle and is often combined with other treatments for optimal results.
Does minoxidil actually work for hair loss?
Yes — minoxidil is one of the most well-studied hair loss treatments and is effective for both men and women with androgenetic (pattern) hair loss. It works by prolonging the growth phase of hair follicles and increasing follicle size. Topical minoxidil is applied directly to the scalp; oral minoxidil (at low doses) is increasingly used for patients who prefer a pill or who need broader coverage. Results typically become visible after 3-6 months of consistent use.
Are there new treatments for alopecia areata?
Yes. Two JAK inhibitors have received FDA approval specifically for moderate-to-severe alopecia areata: baricitinib (Olumiant) and ritlecitinib (Litfulo). These oral medications work by blocking inflammatory pathways that cause the immune system to attack hair follicles. In clinical trials, a significant proportion of patients experienced substantial hair regrowth — including full scalp coverage in some cases. Our providers can evaluate whether you are a candidate for these newer therapies.
How do I know what type of hair loss I have?
A thorough evaluation is essential because many types of hair loss look similar at first glance but require very different treatments. Our providers will take a detailed history — including timing, family history, medications, diet, and stress — perform a scalp examination, and may use dermoscopy for a magnified view of the follicles. Blood work to check thyroid function, iron stores (ferritin), hormone levels, and nutritional status is often ordered. A scalp biopsy may be recommended when the diagnosis is uncertain.
When should I see a dermatologist for hair loss?
You should seek evaluation sooner rather than later. Hair shedding of more than 100-150 hairs per day, visible thinning, a widening part, bald patches, or scalp symptoms like itching, tenderness, or flaking all warrant a professional evaluation. Early intervention — before follicles scar or miniaturize beyond recovery — consistently produces better outcomes.
