At Metropolis Dermatology in Pasadena, CA, we offer advanced, non-surgical solutions to help restore hair health and density. Our treatment options include Keralase™ laser therapy and Platelet-Rich Plasma (PRP) injections, both designed to revitalize dormant follicles and promote fuller, stronger hair growth—without surgery or extensive downtime.
What Causes Hair Loss?
Hair loss—or alopecia—occurs when follicles shrink, weaken, or enter a prolonged resting phase. While some shedding is normal, chronic thinning or patchy hair loss may signal a deeper imbalance.
Common causes include:
- Hereditary Pattern Baldness – The most common type, often affecting the temples, crown, or part line.
- Hormonal Fluctuations – Such as those caused by pregnancy, menopause, thyroid issues, or birth control.
- Physical or Emotional Stress – Can shock follicles into a shedding phase (telogen effluvium).
- Medical Conditions – Autoimmune diseases like alopecia areata, nutritional deficiencies, and scalp disorders can contribute.
- Medications – Certain prescriptions, including those for cancer, depression, and blood pressure, may trigger hair loss.
Signs You May Be Experiencing Hair Loss
- Gradual thinning across the scalp or at the crown
• Widening part or receding hairline
• Patchy bald spots
• Noticeable shedding when brushing or showering
Hair Restoration Treatments in Pasadena
At Metropolis Dermatology, we take a comprehensive, non-invasive approach to hair regrowth using two leading therapies: PRP injections and Keralase™ laser therapy. Both are designed to improve follicle health, increase hair density, and give your scalp the support it needs to produce thicker, healthier strands.
Keralase™ Laser Hair Therapy
Keralase™ uses a fractional laser to create microchannels in the scalp, allowing specialized growth serums to deeply penetrate and stimulate hair follicles. This method is completely needle-free and helps rejuvenate scalp circulation and follicle activity.
Benefits of Keralase™:
- No injections or discomfort
• Boosts absorption of nourishing peptides and growth factors
• Quick in-office treatments (under 45 minutes)
• Suitable for men and women
• Zero downtime—resume normal activities immediately
• Can be paired with PRP or topical therapies
Platelet-Rich Plasma (PRP) Injections
PRP is a regenerative treatment that uses your own body’s growth factors to support new hair growth. After drawing a small amount of blood, we isolate the platelet-rich portion, which is rich in healing proteins. This concentrated plasma is then injected into areas of thinning hair to nourish and repair weakened follicles.
Benefits of PRP:
• Stimulates natural hair growth using your body’s own cells
• Improves hair thickness and density over time
• Minimally invasive with little to no downtime
• Ideal for early-stage thinning or diffuse hair loss
• Can be combined with other therapies for enhanced results
Which Hair Loss Treatment Is Right for You?
Both PRP and Keralase™ are safe, effective, and clinically backed methods to improve thinning hair and restore scalp health. During your consultation, we’ll assess your scalp, hair density, and medical history to determine which treatment—or combination—is best suited to your goals.
Some patients may benefit from starting with PRP to stimulate immediate follicular repair, while others may find the convenience and comfort of Keralase™ more aligned with their preferences. In many cases, combining both therapies yields the most powerful results.

FAQs
How many hair restoration treatments will I need?
The number of sessions varies based on the severity of hair loss and the treatment used. Most patients see best results with a series of PRP or Keralase™ treatments, spaced 3–4 weeks apart. A typical regimen includes 3–6 sessions, followed by maintenance treatments.
Is PRP or Keralase™ painful?
Both treatments are well-tolerated by most patients. PRP injections involve a quick series of small, shallow injections with minimal discomfort—many describe it as a mild pinch. Keralase™ is completely non-invasive and pain-free, offering a comfortable, relaxing treatment experience.
When will I notice results from hair restoration treatments?
Results develop gradually. Most patients begin to see visible improvements in hair thickness and scalp coverage within 3 to 6 months after starting PRP or Keralase™ therapy in Pasadena.
Can I combine PRP and Keralase™ for better results?
Yes! Combining PRP injections with Keralase™ can enhance overall effectiveness, providing a multi-layered approach to follicle regeneration and improved hair density.
Am I a good candidate for hair loss treatment in Pasadena?
Ideal candidates for non-surgical hair restoration treatments include men and women with mild to moderate thinning, early-stage pattern baldness, or stress-related hair shedding. Our team at Metropolis Dermatology will assess your scalp health and medical history to recommend the right solution.
