Baldness: researchers have developed different techniques to stimulate hair regrowth

In France, 10 million men and 2 million women suffer from alopecia, that is to say of acceleration of the fall of the hair or the hairs. A serious problem that can lead to complex and profound discomfort. Scientists have developed several treatments to stimulate hair regrowth. A molecule found in McDonald's French fries would even be effective. Explanations.

Losing more than 150 hairs a day is considered abnormal. Baldness is usually hereditary and its first signs may appear in the early twenties, on the top of the head, forehead or temples. Over time, researchers have developed several techniques, treatments and operations to stimulate hair regrowth or at least fill the deficit areas.

Drug treatments

Available without a prescription, minoxidil is the most used treatment. Initially, it had been developed against high blood pressure. Then scientists found that it stimulated hair growth. On the other hand, they repel much finer than before and it can cause significant brownouts.

Another possible medicine, the one used by President Donald Trump: finasteride. As an oral drug, finasteride was first used for benign prostatic hypertrophy. It has been approved since 1998 to treat baldness. However, it is subject to surveillance by European health authorities. As a cause, its side effects: decreased libido, erectile dysfunction and ejaculation disorders have been observed. In addition, a viral video reveals that Trump's hairy cover is not as thick as hoped.

And for women?

Women, also concerned with baldness, although to a lesser extent, can use spironolactone. This molecule blocks the hormones that play a role in hair loss.


There are also some surgical methods to fight baldness. First, micrografting or "hair restoration". Its principle is simple: to take hair still healthy, mainly at the level of the crown of the head (here, they are said to be "eternal"), then graft them on the bald areas. This technique is very popular in the United States. In 2016, more than 133,000 people used it according to the International Society of Hair Restoration Surgery (ISHRS). That's 18% more than the previous year.

There is also the technique of the strip. The principle is to take a thin band of scalp on the back of the skull to relocate each follicle on the area to run. Both types of operation are effective but require time and money. On average, each operation lasts two to three hours and cost several thousand euros.

If all these solutions do not suit you, be aware that a recent study shows how a chemical used in McDonald's French fries would help regrow hair.
