Welcome to Downtown Dermatology

Trusted Care in the Heart of Manhattan

Hair thinning and hair loss affect millions of people, and for many, it’s more than a cosmetic issue—it’s a medical concern that deserves expert attention. At Downtown Dermatology, we approach hair loss as the complex clinical condition it is. Led by Dr. Gilberto Alvarez, our board-certified team combines diagnostic precision with advanced treatment options to uncover the root cause of hair loss and create a plan that’s medically sound and personally tailored.

Whether you’re facing hormonal hair thinning, stress-related shedding, or postpartum loss, we provide thoughtful, individualized care rooted in science, compassion, and experience. Our Manhattan practice is built on the belief that every patient deserves a solution that works—and a physician who listens.

How Alma TED Works

Alma TED is a revolutionary hair restoration treatment that uses sound energy and air pressure to rejuvenate your scalp—no pain, no needles, no downtime.

While it’s natural to lose some hair with age, sudden or excessive hair loss can be distressing. Alma TED offers a breakthrough solution for people seeking real results without surgery or medications.

This innovative treatment uses acoustic sound waves and air pressure to deliver growth-stimulating serums directly into the scalp, bypassing the need for needles or invasive techniques. The process is designed to improve blood flow, optimize scalp health, and stimulate dormant follicles—all in a treatment that takes less than 30 minutes and requires no recovery time.

Before beginning treatment, your dermatologist will review your medical history and perform a detailed scalp evaluation to identify the underlying cause of your hair loss. If Alma TED is right for you, we’ll build a personalized treatment plan to help restore hair growth and boost your confidence, safely and effectively.

Alma TED+ before and after.

Are You a Good Candidate for Hair Restoration?

Are You a Good Candidate for Hair Restoration?

Hair loss affects people of all ages and genders and can be caused by a variety of factors, such as genetics, hormonal changes, medical conditions, medications, or even periods of intense stress.

You may be a candidate for hair restoration treatment if you experience:

  • Gradual thinning or widening of the part
  • Shedding more hair than usual in the shower or on your brush
  • Receding hairline or thinning around the crown
  • Overall decrease in hair volume or density
  • Hair loss following pregnancy, illness, or major stress
  • No known medical reason for sudden shedding

Alma TED is particularly well-suited for individuals in early to moderate stages of hair loss who want a non-invasive, needle-free solution, without surgery or daily medication.

Our Process for Treating Hair Loss

At Downtown Dermatology, we begin every hair restoration treatment with a thorough evaluation. This includes a comprehensive review of your medical history and a physical examination of your scalp and hair. Our goal is to determine the underlying cause of your hair loss, because effective treatment starts with the right diagnosis.

Once we identify what’s contributing to your hair loss, we’ll recommend a customized treatment plan tailored to you.

Alma TED: Our signature, non-invasive treatment that stimulates natural hair growth using acoustic sound waves and air pressure.

Topical or Oral Medications: For cases of hereditary hair loss, prescription-strength solutions can help regrow and maintain hair.

Laser Therapy: Non-surgical light treatments that promote follicle health and boost hair density.

Surgical Referral: For patients with advanced or treatment-resistant hair loss, we may refer you for surgical options like hair transplant procedures.

I've been a patient here since Dr Alvarez started and I love the staff here. I recommend Downtown Dermatology to everyone due to the level of care I've received for all of these years. Dr Karp and Dr Alavarez are both good doctors who have dealt with my rare skin condition.

5 stars for Dr. Alvarez, 1 star for the unresponsive administration:

Dr. Alvarez is great, but the administration has been frustrating. I received an attempted $138.77 charge on my credit card via email, with no invoice explaining the charge. I immediately asked for the invoice, noting that my insurance had already paid through my HRA. They claimed an invoice was sent, but I never received it and asked them to resend it—no response. My insurance confirmed payment and tried contacting the office, but their calls went unanswered. Weeks later, I followed up again and was told my balance was now $0, yet they still never provided the invoice. Despite multiple follow-ups and calls, I've heard nothing back. It feels like they tried to charge me without justification and then dodged accountability. Very sketchy and concerning

Dr. Karp is truly amazing! From the moment I walked in, I felt welcomed and at ease. She's incredibly knowledgeable and took the time to explain everything clearly, making me feel comfortable and confident in her care. I actually came to see her on a bit of a whim when my regular dermatologist couldn't get me in, but honestly, I won't be going back. Dr. Karp's exceptional care and welcoming demeanor have won me over completely. Highly recommend!

Dr Alvarez is incredible - by far my favorite doctor. He has helped me with a multitude of issues - advocating to my insurance for necessary care and offering me options for everything. He and his team are dedicated to giving excellent, welcoming, quality care - and they have great views from their office. I highly recommend him to anyone looking for a derm.
