demonstrate the proper technique for chemical hair relaxers

1. chemical hair relaxing is the process of rearranging the structure of curly hair into a straighter or smoother form.
2. the chemistry of relaxers and permanent waving is exactly the same.

_____ true ✓ false

1. the most common types of chemical hair relaxers are thio relaxers, hydroxide relaxers, and soft - curl perms.

Explanation:

To address these questions, we analyze each one based on cosmetology (a subfield of Natural Science, specifically related to health and beauty services):

Question 105

• Explanation: Permanent waving (perming) techniques for men’s and women’s hair share core principles (using chemicals to restructure hair bonds), so the statement “requires different techniques” is false.
• Answer: False

Question 107

• Explanation: Home hair coloring products often contain metallic salts (e.g., from henna or old formulas), which react negatively with permanent waving chemicals (like thioglycolate).
• Answer: Metallic salts

Question 108

• Explanation: Chemical hair relaxing is defined as rearranging curly hair’s structure to be straighter/smoother via chemical agents (e.g., hydroxide relaxers).
• Answer: Chemical hair relaxing

Question 109

• Explanation: Relaxers (alkaline, break disulfide bonds) and permanent waves (acidic/alkaline, restructure bonds) have different chemistry (relaxers focus on straightening, perms on curling). Thus, the statement is false.
• Answer: False

Question 110

• Explanation: Common chemical hair relaxers include:
• Hydroxide relaxers (e.g., sodium, calcium, lithium hydroxide) – strong alkalis.
• Thio relaxers (use thioglycolate, similar to perm solutions but for straightening).
• Ammonium thioglycolate relaxers (less common but still recognized).

(Note: The handwritten answer has errors; correct terms are “hydroxide relaxers,” “thio relaxers,” and “ammonium thioglycolate relaxers” or similar standard categories.)

• Answer: Hydroxide relaxers, thio relaxers, ammonium thioglycolate relaxers (or standard equivalents)

For Question 106 (safety precautions), the first step in permanent waving safety is typically analyzing the hair and scalp (to check for damage, porosity, etc.) to ensure safe processing.

For Question 104, a “partial perm” is recommended for adding volume to a specific area (targeted perming).
