Regular trimming doesn't make your hair grow faster
Many people like to go to the barber shop often to get their hair trimmed, on the one hand, for the sake of a good hairstyle, and on the other hand, they also have the idea of "trimming a little shorter hair will grow faster".
But in reality, our hair grows outward from the hair follicles, and trimming the ends of the hair doesn't have any effect on the hair follicles on the scalp, so it's unlikely that you can make your hair grow faster in this way. The growth rate of hair is related to an individual's metabolism, nutritional status, health status, etc.
In general, a normal person's hair can grow about 1 2 cm a month.
Yellow hair ≠ malnutrition
First of all, the color of hair is related to the pigment contained in the hair follicle, which is determined by the person's genes, which is similar to the color of the person's skin. So when your hair is slightly yellow, it's not a big deal.
The oily hair of the head may be due to mites
When it comes to mites, the first thing that may come to mind is quilts, but in fact, we also have mites living on our scalps. Head mites are lipophilic microscopic organisms, as are genetic or hormonal imbalances, and are one of the main culprits of hair loss.
It lives in human hair follicles, feeds on sebum, and after eating, it secretes a lipolytic enzyme to help digestion, which will further break down and erode the sebaceous glands in the scalp to block the hair follicles, causing the hair follicles to shrink due to lack of nutrients, resulting in hair loss or baldness. For head mites, we should first wash our hair frequently to ensure that the hair is clean, and secondly, we should pay attention to head hygiene, change bed sheets and pillowcases frequently, and be careful not to mix personal items such as combs.
Does hair that is too long absorb nutrients from the human body?
Every hair is made up of hair follicles, hair roots, and hair shafts, and when we say hair length, we mean hair shafts, which are dead cells that have no metabolism and do not consume nutrients.
Only hair follicles consume nutrients when they are metabolized, and the nutrients consumed are only a very small part of the nutrients required by the body, and the rest of the hair does not consume nutrients. The metabolism of hair follicles is going on all the time, and it has nothing to do with the length of your hair, so you don't have to worry about your hair and your brain stealing nutrients.
