  • Why Does the Hair Just Not Sit on Some Days?

    Why Does the Hair Just Not Sit on Some Days?

    It’s like a jinx on those days when no amount of blow-drying, gel, or styling can make your hair stay put. It either droops down or stands on end as if electrified. These days, a lack of style doesn’t simply leave your hair looking unkempt; it may also have a psychological impact on you. Strange as it may seem, “bad hair days” really do only last a single day. As usual, by the next morning, everything is in its right place again. But what is the reason for “bad hair days”? Can you blame the weather? Do hormones have a role here? Or is it just imagination after all?

    This phenomenon is indeed real. There are days when your hair is oilier or more resistant than normal. And for many people, it is a real hindrance when the hairstyle just won’t sit.

    The sebaceous glands are affected by hormonal shifts

    So, what causes these “bad hair days”? Hormone fluctuations are a probable explanation. Sebum production on the scalp and, by extension, hair oiliness, is altered as a result of this fluctuation. The hormonal shifts associated with menstruation play a part in this phenomenon in females. In the third week of the period, for instance, the hair may get oilier than normal.

    The weather also influences the fit of our hairstyle. The hairs are more prone to being electrically charged in dry air, such as that seen in warm areas during the winter. They crackle when combed and stick flat to the scalp. A similar charge can be generated by friction on the pillowcase. Using silk bedsheets can prevent this. Silk is easier on the hair since it causes less friction.

    Humidity in the air is another factor that may make a hairdo seem unflattering. Humidity is especially bad for people with curly hair because it makes the small flakes along the hair spread. This results in unmanageably wild hair that is impossible to comb through.

    Afflicted hair responds more sensitively

    The question is why some individuals appear to have more terrible hair days than others. Hair quality is often cited as a contributing factor to this. The most vulnerable individuals are those who already have hair that is difficult to comb due to an afflicted surface. This is especially true for those with longer hair.

    Simply put, the protective coating at the ends of these hairs has been stripped away. Thus, they are more sensitive to changes in climate and other aspects of the environment. But it’s not true that only women ever have a bad hair day. Trichologists believe that a bad hair day happens to both men and women.

    Men tend to be more antisocial, and women are more prejudiced

    Yale University psychologist Marianne LaFrance has investigated the psychological effects of having a bad hair day on both sexes. Strangely enough, bad hair days are experienced by both sexes. But she claims that the response is different. When their hair looks bad, women tend to feel inferior, ashamed, and humiliated. Men are often more reserved, lack self-assurance, and exhibit greater anxiety than women.

    When having a terrible hair day, people of both sexes are far more critical of their own talents than they are of those of others. It turns out that something as seemingly inconsequential as a bad hair day may have a profound effect on your sense of self-worth.

    On a day when your hair doesn’t cooperate, it’s crucial that you not let that fact stress you out. Forceful attempts to shape the hair are futile and will only damage it. It’s more practical to braid it, conceal it, or try another style.

  • What Makes Hair Grow Curly or Straight?

    What Makes Hair Grow Curly or Straight?


    Beach waves, gentle waves, curly curls, or corkscrew curls. There are many variations of curly hair. But what determines the structure into which our hair develops? Curls have cultural importance and, in certain cultures, are even seen as the epitome of beauty. 3,100 years before the Common Era, even the ancient Egyptians attempted to curl their hair artificially, as shown by clay curlers discovered by researchers in Egypt. However, not everyone needs curlers and papillotes.

    The Curl Is Made by the Follicle

    Every hair begins on the scalp, where a hair follicle surrounds a hair root that is embedded in the skin and has a hair shaft that protrudes from the skin. The primary determinant of the structure a hair adopts is the hair follicle from which it emerges.

    The Curl Is Made by the Follicle

    Keratin protein fibrils are converted into hair in the hair follicle. Because one cysteine, an amino acid that contributes to the formation of keratin, creates a “disulfide bridge” with another cysteine, these keratin fibrils cross-link with one another. The number of these cross-links that develop between a hair’s fibers determines how curly the hair will be.

    Forms of Hair

    Now, if the keratin fibers are pushed closer together during hair development in the hair follicle by a certain oval and narrow follicle shape, they may generate more disulfide bridges and the hair grows curlier.

    On the other hand, when a highly rounded follicle shape hinders the development of many such connections, the hair grows straight. Additionally, the follicular tunnel’s form is important. A straight follicular tunnel promotes smooth hair growth, while a curved follicle tunnel aids in the development of curls.


    Does a “Hair Gene” Exist?

    Why then do some people have straight hair follicles while others have curved ones? The trichohyalin gene (TCHH), which is read out in the cells of the hair follicles, is thought to be the cause of curly hair.

    Scientists believe that Europeans often have smooth hair because of a DNA mutation that assures a certain follicle form. The precise reason for the variation in hair follicle morphology hasn’t yet been definitively determined.

    However, the majority of scientists concur that curly hair is mainly inherited. It is quite probable that the children’s hair will be curly if one or both parents have curly hair.

    However, the hair structure that is inherited from our genes may change throughout time. Many people have straight hair as children, which starts to curl as they become older, or vice versa.

    Although there hasn’t been any conclusive study on this one, it is thought that variations in hormone balance may have an effect on hair texture.

    As a result, nature comes up with many techniques to curl or wave our hair. But what about the techniques that are used at hair salons when someone wishes to alter the structure of their hair? Conventional curlers change the formation of hydrogen bonds in our hair.

    These connections may be broken by the curlers’ heat, which will change the form of the hair. New bonds are created as the hair cools back down in that shape, keeping it there for some time.

    The process of straightening hair is similar.

    However, because of how easily moisture may break these connections, the hair immediately assumes its previous structure.

    Consequently, trying to artificially straighten or curl the hair on a wet day is often ineffective.

    Perming, on the other hand, is a longer-term solution. Strong disulfide bridges that exist between the keratin fibers are broken using so-called reducing agents.

    The development of new disulfide bridges is induced by using an oxidizing chemical after the hair has been given the proper shape. The curls endure considerably longer since it is difficult for water to readily dissolve them once again.
