Parting ways with traditional scalp treatment
Recent trials and exciting advancements show great promise.

A hair disorder or perceived deficiency can easily impact a person’s confidence or quality of life. The most common hair-related dermatology condition in the United States — and worldwide — is androgenetic alopecia. However, it can be frequently misdiagnosed or mistreated.
Addressing patients’ scalp and hair health has not always been prioritized in the cosmetic dermatology field like skin care has, said Suleima Arruda, MD, FAAD, a dermatologist in São Paolo, Brazil, and clinical director of Sadick Research Group in New York City. Dr. Arruda has seen and treated all types of dermatologic diseases, but it’s only in the past several years that she’s witnessed cutting-edge advancements in the treatment of hair and scalp conditions.

Root cause
When it comes down to it, said Dr. Arruda, many patients do not realize that healthy hair starts (and ends) with a healthy scalp. People with hair disorders often experience inflammation, which is a leading contributor to other symptoms such as itching, flaking, sensitivity, and hair shedding.
Treating scalp disorders with the novel procedure known as hydradermabrasion helps to stimulate blood flow, hydrate skin, and deeply cleanse a patient’s scalp.
“This device promotes a healthier microbiome, decreases inflammation, and helps topical medication to better penetrate the scalp,” Dr. Arruda said. “I see us moving from treating scalp disease and extending to cosmetic dermatology and aesthetics as well as educating our patients about hair care based on science and research.”
Applied learning
Dr. Arruda said it is critical that dermatologists continue to investigate, discover, and improve treatments for hair and scalp conditions. These opportunities will lead to new therapeutic techniques and applications with real-life implications for patients.

Additionally, trials are underway to assess the benefits of platelet-rich plasma (PRP) and exosomal therapy to help regenerate hair growth.
