This, by the way, is also found in the nails, in fact it is keratin that makes them flexible and without it they would be very rigid. Another interesting fact about hair is that it is very strong, as strong as iron, in fact, a single strand can support a weight of up to one hundred grams.

. We humans lose up to 100 strands of hair a day, but we have quite a bit of hair to begin with. There are some variations depending on hair color, but for the average adult, the strand counts at one hundred thousand, so losing a hundred a day isn't that bad, although this is the average: red-haired people have about 80,000 strands of hair. black or brown hair, 100,000 and blondes have around 120,000, so hair used to be important for the reasons I mentioned above, but Nowadays, I would say that the main importance of hair is the fact that it is a big business, apart from the money involved in cutting hair, shaving, trimming, etc.

general of the lock. hair, the last part is the shaft and this is the hair that is above the skin and of course that is what we can see.

Fortunately, this is not active and I say fortunately because otherwise it would be very painful to cut your hair and finally, I would just like to go over some factors that impact the overall health of hair, like any other part of the body, our diet, it is That is, what we eat is extremely important for the condition of our hair, but a change in your diet, for example, eating unhealthy foods will soon be noticeable on your skin.
