Research Demonstrates Potential of Platelet-Rich Plasma Therapy for Hair Loss
Board-certified dermatologists can help patients determine the best treatment option for them
Tens of millions of people in the U.S. experience hair loss, which can have a significant impact on the quality of life. There is more hope on the horizon, however, as a growing amount of research indicates that a procedure known as platelet-rich plasma therapy can provide effective treatment.
“A general body of evidence has recently emerged demonstrating a positive response from PRP treatments,” says Jeffrey Rapaport, MD, FAAD, a board-certified dermatologist in private practice in New Jersey. “With consensus forming around treatment protocols, studies are indicating that PRP is a safe, effective hair loss treatment that has the potential to greatly improve the quality of life of millions of people.”
PRP therapy originated in Europe more than a decade ago and has been utilized in a variety of medical areas, including orthopedics and dentistry. The procedure involves placing blood drawn from the patient into a special machine that separates red blood cells from plasma, which is rich in platelets that contain growth factors.
In hair loss therapy, the plasma is directly injected into the patient’s hair follicles in a process that takes no more than 10 minutes, according to Dr. Rapaport. Since the procedure involves only minimal discomfort, he says, patients typically do not require any numbing or downtime following therapy.
After the initial treatment, injections are repeated once a month for the next three months, and then once every three to six months after that. Within the first few months of treatment, patients may notice they are losing less or minimal amounts of hair, Dr. Rapaport says, and soon after, they may begin to see an increase in thickness or eventual regrowth.
While not everyone is a candidate for PRP therapy, Dr. Rapaport says that it has been found to have high success and satisfaction rates in certain hair loss patients, including those with hereditary hair thinning or baldness. He recommends that those considering the procedure consult with a board-certified dermatologist to determine if it’s the right option for them, adding that PRP may be used in conjunction with other treatments to give patients the best possible results.
“Since PRP therapy has taken off, there have been a lot of non-dermatologists performing this procedure,” Dr. Rapaport says. “Only board-certified dermatologists have the medical training to identify if you are a good candidate, because this treatment will not work for everyone who experiences hair loss. Talk to a board-certified dermatologist to determine which hair loss treatment option is best for you.”
With more than 35 million men and more than 21 million women currently suffering from hair loss in the United States alone, it is easy to understand why fear of losing hair is something that can affect us all. This fear has led many to speculate wildly about things that could potentially help, or worsen, hair loss. While the majority of these myths about hair loss represent either wishful thinking or unfounded paranoia, one common belief, specifically that hair loss becomes more pronounced during the autumn and winter months, may actually have some validity. A study published by the journal Dermatology in 2010 documents how scientists tracked regular cycles of hair shedding in 800 healthy women over the course of six years and found that, on average, the group lost more hair during the autumn months. To help understand why, we need to take a close look at the natural hair growth cycle.
Each of the 100,000 to 150,000 individual hair follicles on the human scalp goes through a life cycle of growth and shedding that can be influenced by age, disease, and a wide variety of other factors. At any given time about 90% of the follicles are in the actively growing, or anagen, stage, while the other 10% are in the telogen (or “resting”) phase. Those in the telogen stage remain there for approximately two to six months before their hairs are shed to make room for the next cycle of growth. However, any kind of severe physiological or emotional stress, like a car crash, undergoing major surgery, or even the death of a loved one, can potentially trigger temporary hair loss, in the form of a condition called telogen effluvium where a greater than normal number of hair follicles all enter the telogen phase at once. About two to six months after whatever trauma initiated the telogen effluvium, all of these follicles shed their hair at the same time, making it appear as though the patient is suffering widespread hair loss.
Some scientists speculate that the seasonal trend in hair loss is the result of a similar phenomenon. Harmful ultraviolet radiation from the sun, which is far more prevalent in the hot summer months, triggers a higher than normal percentage of follicles to enter the telogen phase around July, which means that by about October or November those follicles are ready to shed. Moreover, some damaging hair styling practices and environmental factors common to the cooler months can further exacerbate the problem. Long term exposure to artificially heated air from a furnace or central heating unit can dry out the hair, while hot water, heated curling and flat irons, and hair dryers strip moisture and essential oils. Ultimately, this damage can make the ends of the hair strands appear frayed, a condition commonly known as “split ends”, and can make any hair loss that may be occurring far more noticeable.
Fortunately, the hair loss that results from telogen effluvium is usually only temporary. The hair follicles are not permanently damaged, so if the particular external cause that triggered the condition is short lived, the hair follicles should return to their growing state and start producing new hair strands within six months.

Excerpts from Dermatology Times 7/20/16
School will soon be back in session, and unfortunately, this usually means an uptick in the incidence of head-lice. Do you know what to do if your child comes home from school with lice?
Here are a few helpful tidbits about the world of lice: Head lice die in one to two days without feeding, and nits die within a week and cannot hatch if they are not near the scalp; Nits (lice eggs) alone do not indicate contagiousness; However, behaviors such as sharing brushes, combs or pillows could transfer nits or lice from person to person; Once hatched, lice move by crawling – they cannot hop or fly; Pets do not play a role in transmission of human lice.
What to Do
If lice are found on someone, machine wash and dry all clothing and bed linens worn or used in the two days before treatment. Items that can’t be washed should be placed in sealed plastic bags for two weeks. Soak combs and brushes in hot water (at least 130°F) for five minutes. And vacuum the floor and furniture around where the infested person sits or sleeps, then discard the vacuum contents in a sealed plastic bag. In addition to these actions, topical treatments may be used to kill the lice and nits on the persons scalp and hair.
According to Dr. Raegan Hunt, lice are becoming more immune to traditional over-the-counter treatments like Rid and Nix. Earlier this year, a study examined head lice in 48 states and found 98% had developed mutations. The good news: “There are several fairly recently FDA-approved topical lice treatments that can be used to combat the resistant ‘super lice,’” says Dr. Hunt, a pediatric dermatologist at Texas Children's Hospital:
Well-known treatments, such as Rid or Nix, are comprised of permethrin lotion 1%, and may not work due to the development of drug resistance.
Malathion lotion 0.5% (Ovide) works in a single application for most patients, but is limited to those 6 and older. Resistance has been reported in the United Kingdom.
Ivermectin lotion 0.5% (Sklice) got FDA approval in 2012. It kills baby lice (nymphs) and works as a single application on dry hair without nit combing. It’s approved for children 6 months and older.
Spinosad 0.9% topical suspension (Natroba) was approved by the FDA in 2011. It’s approved for children aged 4 and up, and is also effective as a single application on dry hair without nit combing. Retreatment is usually not needed.
Benzyl alcohol lotion 5% (Ulesfia) received FDA approval in 2009 and requires repeat treatment on the ninth day. It’s approved for ages 6 months to 60 years.
After treatment, if you see large, live lice, they may be a sign of a re-infestation. Also, according to Dr. Hunt, lice of different sizes can be a sign of possible resistance to treatment.
