The Reasons Why Nose Hair Thickens with Age.

As we age, our hair tends to thin, and the strength of hair roots weakens, making it more susceptible to hair loss. Surprisingly, however, nose hair tends to become thicker and longer with age. Let's delve into the reasons behind this phenomenon.

 

Finally, the elderly and individuals with chronic conditions should exercise particular caution when handling nose hair. Bacterial infections or inflammation can occur, so vigilance is essential.

 

These changes are related to the male hormone 'testosterone'. Testosterone transmits a 'hair growth signal' to the follicle cells surrounding the hair root. As we age, testosterone combines with a specific enzyme (5-alpha reductase), leading to an increase in DHT (dihydrotestosterone) levels. While DHT can trigger hair loss on the scalp, it promotes hair growth in the nose and chin.

 

When DHT reaches the follicle cells in the scalp, it sends signals for cell death. However, when it reaches the follicles in the nose and chin, growth-promoting factors are generated. This leads to hair loss on the head, but thicker nose hair or facial hair. The same principle applies to the lengthening of eyebrows. However, the exact reason why DHT has opposite effects on the head and the nose is not yet fully understood.

 

It is not advisable to pluck nose hair for cosmetic reasons. Nose hair plays a role in regulating humidity and temperature, as well as filtering out foreign substances. Instead of plucking with your hands, it is better to use specialized scissors to trim the protruding ends of nose hair. Additionally, when using a nose hair trimmer, it is important not to insert it too deeply into the nostrils. Excessive removal of nose hair can impair its function and potentially damage the nasal mucosa. Always exercise caution and follow the principle of removing only the front-facing nose hairs when using a trimmer.

 

Finally, the elderly and individuals with chronic conditions should exercise particular caution when handling nose hair. Bacterial infections or inflammation can occur, so vigilance is essential. It is recommended to choose appropriate methods for nose hair maintenance to keep it healthy.
