In the ever-evolving world of TikTok, a platform renowned for its array of beauty hacks and trends, it’s essential to exercise caution when considering which ones to embrace and which to avoid. Among the list of beauty trends that should undoubtedly fall into the latter category is “hair cracking” or scalp popping, a practice that has garnered attention on the platform.
Scalp popping typically involves one person yanking on another person’s hair to produce a popping sound. Although it might seem like an innocent and harmless trend, TikTok-famous dermatologists have issued stern warnings against it. But what motivates people to engage in this practice in the first place? We consulted an expert to delve into the phenomenon and its potential dangers.
What Is Hair Cracking?
Hair cracking, as depicted in TikTok videos, involves rapidly pulling on a hair’s root to create a popping sensation. According to dermatologist Muneeb Shah, MD, of Hudson Dermatology and Laser Surgery in New York City, the popping sound is a genuine occurrence. Dr. Shah explains, “The popping sensation is an audible noise produced when the galea aponeurotica separates from the underlying tissue.” The galea aponeurotica refers to the fibrous connective tissue within the scalp. Although the practice has historical roots in some Asian cultures, where it is believed to alleviate ailments such as migraines or coughs, it lacks support in Western medicine.
Theoretically, scalp popping can be performed by anyone, regardless of their hair type. Dr. Shah states, “Everyone has a similar anatomy when it comes to layers of the scalp.” However, he emphasizes that individuals with fragile or damaged hair are more likely to experience hair breakage rather than achieving the desired popping sound. This brings us to the potential risks associated with attempting this trend.
Hair Cracking Risks
Hair cracking offers no scientifically proven benefits, and Dr. Shah likens it to knuckle cracking, where the act may be entertaining but holds no clinical advantages. In contrast, there are tangible and significant risks involved, and the practice can be painful.
Dr. Shah cautions that while the galea itself lacks blood vessels, there are numerous blood vessels above and below this tissue layer. Separating these layers can lead to bleeding, albeit uncommonly. A more likely risk is traction alopecia, a form of permanent hair loss caused by excessive pressure or trauma to the hair follicle.
In light of the lack of proven benefits and the presence of real risks, Dr. Shah offers a crucial piece of advice: “Don’t try everything you see on TikTok.” It serves as a valuable reminder to approach trends and hacks on social media platforms with discernment and prioritize safety above all else.
