1. Aesthetic Fashion Increase self-confidence
2. Increase hair volume
3. Change hair flow direction
4. Modify head shape and face shape
Analysis of Chemicals
1. Classification of chemicals
Resistant, normal, damaged.
Choose appropriate perm chemicals based on different hair types.
Agent No.1 (Softening Agent)
1. Ethanolamine; Alkaline substance Only it can break the strongest disulfide bonds in hair.
2. Ammonia; (Ammonia water) Alkaline substance Can expand hair, open cuticle, allow other components to enter.
3. Moisturizer; Maintain hair humidity and luster, replenish moisture and nutrients.
4. Fragrance; Mask ammonia odor.
5. Water
Agent No.2 (Oxidizing Agent)
1. Brominating agent; Fix chain bond structure.
2. Sodium peroxide; Reconstruct disulfide bonds, oxidize chain bonds to fix shape.
Agent No.3; Post-perm care Close cuticles, remove residual alkaline components, restore hair luster.
Chemical Process of Perming
Through ammonia opening the cuticle, disulfide bonds are broken by ethanolamine. Then through curling rods change the chain bond structure, use brominating agent and sodium peroxide from Agent No.2 to fix the shape. (Fission reaction - forcing displacement - recombination - position fixation)
Washing;
Use professional shampoo (cannot damage scalp as ethanolamine is a very irritating alkaline component)
Do not massage
Time should not be too long
Do not apply conditioner
Hair Trimming;
Layering is preferably even or gradually increasing layers
Technique
