S-SDisulphide bonds.
Salt bonds, hydrogen bonds, disulfide bonds
When neutralizer is applied to hair, it breaks down the hair's cysteine and sulphur bonds. This allows curls to form and stay for a while.
Disulphide bonds. A covalent bond between two sulfur atoms.
The Hydrogen bonds are broken and reformed
Polypeptide bonds
Lanthionization is the process by which hydroxide relaxers permanently straighten hair. It breaks the hair's disulfide bonds during processing and converts them to lanthionine bonds when the relaxer is rinsed from the hair. Disulfide bonds contain two sulfur atoms. Lanthionine bonds contain only sulfur atom. The disulfide bonds that are broken by hydroxide relaxers are broken permanently and can never be re-formed.
Hair in good condition is flexible and elastic. The hair is twisted under pressure into curved shapes. It is stretched outward of the curve and it is flattened on the inner side. When it is dried in this position curl will be retained. This occur when hair is set the hydrogen bonds and salt bonds between the keratin chains of the hair are broken linking system is changed into a new temporary position but the stronger disulphide links remain unbroken. The Alpha Keratin This is when the hair is in natural and unscratched shape.It will return to its natural shape either when wet or due to atmospheric moisture.Hydrogen bonds in the hair are broken down during physical prosesses such as shampooing and blowdrying. The Beta keratin (Gives a new shape) state within the hair are only formed when the hair is completley dry example when you do a blowdry.The keratin bonds of streached hair are in beta keratin state.
When choosing a hair style or a hair styling technique, it is important to consider pre-styling hair length before beginning the styling process. Flat irons can make the hair appear longer while things like hot rollers and curling irons can make the hair appear much shorter.

Factors such as texture, hair color, skin tone, and length should be considered before and during the styling and dressing of the hair. Certain colors and styles complement different hair types.
it breaks up the hair structure and reforms the bonds into its new stlye? alpha keritin is hair in its naturall state, beta kertin is after it's been styled
b describe the physical effects of styling techniques on the hair structureHair becomes BETA KERATIN.Hair goes into a Cohesive set.When the hair is dried into a stretched shape it keeps this shape because the Hydrogen & Salt Bonds reform into a different pattern.
Hair should always be damp when drying as when the hair is wet the hydrogen bonds are broken down and this makes it alot easier to shape and style the hair as desired x
