>Scientists may have discovered a breakthrough treatment that could help reverse hair loss by using microRNA. herkisi/Getty ImagesScientists say hair follicles become stiffer as we grow older, contributing to hair loss.However, a new study found that a type of microRNA helps to soften the follicles, aiding hair regrowth.Experts say this could lead to the development of a new treatment for baldness.More work is needed, however, since only mice studies have been done so far.Male pattern baldness, a type of hereditary hair loss, is very common among men. In fact, about two-thirds of men will experience an appreciable amount of hair loss by the time they reach age 35. And, by the age of 50, this figure rises to 85%. Additionally, a quarter of men will begin to have hair loss even before they are 21.Hair loss can be troubling for men with many reporting that their baldness makes them feel less attractive, depressed, or fearful of growing older.Now, however, researchers say they may have found a promising new treatment for this often emotionally distressing condition.According to the study authors, hair follicles become stiffer due to aging.However, their study, which appears in the journal PNAS, found that softening hair follicle cells by increasing the production of a particular type of microRNA could aid in increasing hair growth and regeneration.Tiny RNA particles may be the key to reversing baldnessAccording to board-certified cosmetic dermatologist Dr. Michele Green, who was not involved in the study, hair follicles have various stem cells that are responsible...Continue reading
