    Study Notes

    Sodium Hydroxide Relaxers

    • Have an alkaline pH of 11.5-14.
    • Commonly known as lye relaxers.
    • Typically used on tightly curled hair.

    Ammonium Thioglycolate Relaxers

    • pH level ranges around 8.5 to 9.5.
    • Strength labeled as mild is ideal for healthy, color-treated, fine-textured, or porous hair.
    • Also utilized for curl reformation and softening hair.

    Relaxer Application

    • An acid-balanced neutralizing shampoo or stabilizer is applied post-relaxer to eliminate chemicals and excess moisture.
    • Protective creams or base creams are essential to shield the scalp and hairline from chemicals during the application.
    • Virgin relaxers should be applied 1/4 to 1/2 inch from the scalp for optimal results, as body heat helps spread the product.

    Curl Patterns and Texture

    • Curly hair is generally associated with an elliptical follicle.
    • To achieve an s curl pattern, 75% of the curl must be removed during the service.
    • A pull test is used to assess hair elasticity.

    Chemical Interactions

    • Sodium hydroxide and ammonium thioglycolate should not be mixed, especially if hair has previously been permed with ammonium thioglycolate.
    • Extreme breakage post-relaxer can result from improper neutralization or overprocessing.

    Professional Practices

    • Clients should refrain from shampooing their hair for 48 hours before a sodium hydroxide relaxer service.
    • The importance of consulting clients about their relaxer history is crucial in determining the appropriate service.

    Curl Reformation Services

    • Curl reformation involves thinning the natural pattern, typically requiring a thinner than normal parting during application.
    • Chemical blowout or curl diffusion is a process that reduces curl by about 50%.
    • The main ingredient in curl boosters and rearrangers is ammonium thioglycolate.

    Treatment and Aftercare

    • Lost moisture and protein from chemical processes can be replenished using protein or moisturizing conditioners.
    • Natural oils are restored by applying conditioning treatments after relaxing.

    Miscellaneous Facts

    • Zonal relaxers are targeted services performed in selected hair areas like the nape or sides.
    • Historically, Madam C.J. Walker invented a temporary hair relaxing method in the early 1900s.
