DISCOVERY: Drug That Really Kills Baldness

Reversing hair loss is notoriously difficult, but a new study may bring scientists one step closer to solving the hair loss puzzle.

Approximately 88 million men and women experience some degree of hair loss during their lives.

Those eager to reverse a receding hairline can choose from a few solutions. Hair transplants are a costly but permanent option. Topical solutions that promote hair growth, but at inconsistent rates, are another option.

Hair loss is the result of both hormonal and hereditary factors. The truth is, hair loss is still a bit of a mystery, said Dr. Edidiong Kaminska. She practices dermatology in Chicago and is a spokesperson for the American Academy of Dermatology.

“There are so many molecular pathways — it’s multifactorial, it’s hereditary. There are a host of factors,” she told Healthline. “That’s why treating hair loss has been complicated and challenging.”

Uncovering a new possible treatment for hair loss

A study released in May 2018 may bring scientists one step closer to solving the hair loss puzzle. It involves a drug that’s currently used to treat osteoporosis.

One of the side effects of the drug is that it reduces the activity of a protein called SFRP1. This is key because that protein also stops follicles from growing hair.

The hair follicles were placed in a medium and treated with the drug. Researchers said that those hair follicles were able to grow again because it suppressed the actions of SFRP1.

Kaminska said it’s exciting to see that the researchers were able to zero in on the protein that stops hair from growing at the follicle.

“This is novel because it blocked that protein, SFRP,” she said. “It’s amazing that they were able to find the specific protein.”

“I can’t say it’s the magic bullet, but it’s exciting,” she said.

From treating osteoporosis to fighting hair loss

At first the researchers conducted studies using cyclosporine A, an immunosuppressant. One of its side effects is hair growth. That set of testing led them to the SFRP1 protein and the discovery that the protein blocks hair growth. But cyclosporine A has too many side effects to pursue further testing, which is why they set their sights on the osteoporosis drug.

It has few side effects. It should be noted that the scientists didn’t provide the name of the drug in their study.

“The fact that this new agent, which had never even been considered in a hair loss context, promotes human hair growth is exciting because of its translational potential,” he said in his statement.

Why is it so difficult to stop hair loss?

While hair loss has likely been occurring as long as humans have been around, it’s only in the last 40 years that consumers have had access to topical treatments that encourage hair growth.

And these medical options don’t help everyone or treat every type of hair loss.

The most common treatment for hair loss — minoxidil — was introduced to the masses in 1998. The drug is often referred to as Rogaine, one of the most popular brands on the market.

Despite its popularity and widespread use, scientists aren’t actually sure how minoxidil promotes hair regrowth, but it does.

The drug, a topical treatment, was first used to treat hypertension, and hair growth was a side effect. More than 40 percent of people who use minoxidil will see their hair grow back to some degree.
