What Does Science Say About Hair?
The truth is that from the moment you leave the shower, your hair begins a gradual process as the days go by; it becomes brighter, darker, and greasier.
That occurs for the same reason that your face becomes greasy.
The glands in the skin produce an oily substance called sebum. The sebum is what moisturizes and prevents it from drying out.
The sebum-producing glands (called sebaceous glands) located next to its roots in the layer of skin called the dermis.
The channels of the sebaceous glands lead to the hair follicle, and this is how the sebum leaves the skin and reaches the scalp.
Also, the hormones responsible for the increased production of sebum triggered during puberty, which is what makes many people have more greasy hair and acne during those difficult years.
Since it depends on each person, we can find some familiar places.
The first and most obvious: experts indicate that no one should have to wash it every day, a myth that has been repeated many times over time.
Moreover, as explained dermatologist and director of the clinic for hair Center, washing too often can do more harm than good:
It is paradoxical, but people who wash it a lot to get rid of dirt, dry the scalp, and produce more oil.
In addition to avoiding washing it (shampoo, of course) every day, there are other things to keep in mind when trying to determine the correct amount of cash for each.
Obvious. Experts explain that if your skin and hair are somewhere healthy (you don’t have super oily or dehydrated hair) when it comes to drying, you probably only need to wash it once or twice a week, as indicated in one Columbia University research.
In contrast, if you have an oily scalp, you probably need to wash it more frequently, 3-4 times.
This point is essential because it affects how quickly the sebum acts from the roots to its length.
Coarse or curly hair slows down the spread of sebum. So if you have this type, only need to wash it once a week, experts at Columbia explain.
However, people with beautiful, straight hair probably need shampoo at least twice a week or even three.
Use Of Treatments For Hair
The last factor includes all those treatments and products that you use (or not) daily or very frequently.
In that case, and if your hair suffers enough styling changes or is damaged. So experts recommend that you should wash it less often.
Having said all this, probably the best way to find out. And where your hair based on these recommendations from the experts. But is to test washing days without them.
No one can better than you what is best.
