The three types of side bonds are hydrogen, salt, and disulfide bonds.
Additionally, Which side bond is the strongest?
Disulfide bonds are also known as Cystine bond, Sulfur bond or S bond. These bonds are the strongest and the protein structures of the hair shaft are held together by chemical bonds called disulfide and hydrogen bonds.
Well, What are the 2 main types of dandruff?

What bonds make hair curly?
With curly hair, there are disulfide bonds that form in the strands that brings the hair closer together forming the curl. This is how the disulfide bonds make hair curlier! When people with straight hair want curly hair, they go and get a perm.

What is the strongest bond in a protein?
Covalent bonds are the strongest chemical bonds contributing to protein structure. Covalent bonds arise when two atoms share electrons.
What causes big chunks of dandruff?
Dandruff may have several causes, including: Irritated, oily skin. Not shampooing enough. A yeastlike fungus (malassezia) that feeds on oils on the scalps of most adults.
Why do I have big chunks of dandruff?
A fairly common condition called seborrheic dermatitis is the cause of many dandruff cases. It’s characterized by patches of red and oily skin that leave yellowish flakes on the scalp. These flakes are often larger than the dandruff flakes that can arise from dry skin.
Is dandruff a fungus?
No one is really sure what causes dandruff. It’s probably caused by a fungus. Hair follicles and oil glands make an oil called sebum, which may be a breeding ground for yeast or the fungus. This fungus usually lives on your skin, but too much fungus may lead to dandruff.
Will baldness be cured by 2020?
Currently, there’s no cure for male pattern baldness. However, medications like finasteride and minoxidil can help you keep the hair you have and, in some cases, potentially regrow some of the hair you’ve lost due to male pattern baldness.

- Leafy Greens. …
- Fruit. …
- Nuts and Seeds.
Why is my hair going straight from being curly?
But hormonal shifts—like those that occur during puberty, pregnancy, and menopause—can alter the shape of the hair follicle. … (Think of the follicle as a tube: If it has a slight curve, the hair grows in curly; if it doesn’t, the hair grows in straight.)
Is curly hair more attractive?
Depends, but in general according to several studies backed by statistics, curly haired people are indeed considered more attractive than people with straight hair.

There’s nothing wrong with using a curling iron or perming your hair if you have straight hair and want wavy hair.
Which type of bond is the strongest of the 3 Side bonds?
The chemical/physical changes in disulfide bonds make permanent waving, curl re-forming, and chemical hair relaxing possible. Although there are far fewer disulfide bonds than salt or hydrogen bonds, they are the strongest of the three side bonds, accounting for about 1/3 of the hair’s overall strength.
How are disulfide bonds broken?
Disulfide bonds can be broken by addition of reducing agents. The most common agents for this purpose are ß-mercaptoethanol (BME) or dithiothritol (DTT).
Is a hydrogen bond?
Hydrogen Bonding. Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.
Are disulfide or ionic bonds stronger?
Apparently, the strongest type of bonding is disulfide. Disulfide is covalent bond, it is stronger than ionic bond. Hydrogen bond is a kind of intermolecular forces and hydrophobic interaction does not form bonding.
Are ionic bonds strong?
Ionic Bonds
They tend to be stronger than covalent bonds due to the coulombic attraction between ions of opposite charges. … Small, highly charged ions will form strong bonds while large, minimally charged ions will form weaker bonds.
Are ionic bonds in proteins strong?
A.
Ionic bonds are formed as atoms of amino acids bearing opposite electrical charges are juxtaposed. Ionic bonds can be important to protein structure because they are potent electrostatic attractions. In the hydrophobic interior of proteins, ionic bonds can even approach the strength of covalent bonds.
How often should you wash your hair if you have dandruff?
In fact, the most effective way to treat most dandruff is to use an over-the-counter shampoo, the American Academy of Dermatology (AAD) explains.
