the physical changes that take place within the hair structure
The physical changes that take place within the hair structure
  • Alpha keratin is when hair is in its natural shape
  • Beta keratin is when hair has been set or blow-dried into a new shape
  • Hair will remain in beta keratin until it is washed or moisture from the air attacks the hair then it will then return to Alpha keratin
poly peptide chain
Poly peptide chain
  • This is made up of keratin
  • The keratin is a combination of -
  • Carbon
  • Hydrogen
  • Oxygen
  • Sulphur
  • Nitrogen
hydrogen bonds
Hydrogen bonds
  • These are temporarily broken during the setting or blow-drying process
wet setting
Wet setting
  • Shampoo the hair to ensure it reverts back to its original state (alpha keratin) as the hydrogen bonds will break when water enters the cortex
  • During the setting or blow-drying process hair is changed to beta keratin and will stay this way until it is shampooed again or until attacked by moisture from a humid enviroment
dry setting
Dry setting
  • You would not shampoo hair before a dry set and the bonds are not as easily broken
  • By applying styling products in conjunction with heat a few bonds will be broken and give a much softer curl
humidity
Humidity
  • This is moisture in the air and as hair has the ability to absorb moisture in a very humid environment this would attack a hairstyle and it would loose its shape due to the hair shaft swelling taking the hair back to alpha keratin
allow hair to cool prior to dressing out
Allow hair to cool prior to dressing out
  • This allows the hydrogen bonds to fix into their new state of beta keratin. It will also allow the style to last longer
