According to the Central Dermatology Hospital, in fact, people with gray hair often pluck it, but a few months later see that gray hair grow back, even more. This makes many people wonder why gray hair grows back in the same place and should they pluck gray hair?
Plucking gray hair too much can cause hair to grow thinner, leading to baldness.
Regarding the cause of this condition, experts from the Central Dermatology Institute explained that hair follicles are like factories, with only small limits. The life cycle of this factory is about 10 - 20 hair cycles, each plucking is a cycle. After plucking, the hair follicles in that area have followed the cycle of pigment synthesis disorder or loss of pigment cells, the hair growing in the new cycle is still gray hair, because the new hair growing still comes from this area of depigmented follicles.
That is why many young people wonder why gray hair often grows in certain places even though they have plucked it. More importantly, after a few plucking cycles, the hair follicles lose their function, gradually making the hair thinner. Some people pluck their gray hair and go bald in patches, affecting their appearance.
Therefore, plucking gray hair can be applied in cases where the gray hair is less than 10%. However, considering the hair cycle, gray hair should not be plucked.
