Thioglycolate lotions are the most popular method for permanent waving and hair straightening.
research Action of Thioglycolic Acid and L-Cysteine on Disulfide Cross-Links in Hair Fibers During Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
research The Swelling Behavior of Hair Studied Through the Structural Change of Keratin Protein During the Permanent Waving Treatment
Hair structure changes immediately during perm treatment, with initial damage partially restored later.
research Permanent Hair Waving
Permanent hair waving uses chemicals to create long-lasting curls.
research Analysis of Structural Changes in Permanent Waved Human Hair Using Raman Spectroscopy
Permanent waving weakens hair by altering its protein structure.
research Preparation and Characterization of Soluble Wool Keratin for Human Hair Care

research Application of an Enzymatic Method for Identifying Hair Treatments
The enzymatic method can effectively identify chemical treatments on hair.
research Non-Invasive Evaluation of Hair Interior Morphology by X-Ray Microscope
X-ray microscopy can non-invasively show hair structure changes after treatments, but it's less detailed than TEM and needs improvement.
research Hair Perms, Straighteners, and Styling Agents
Hair perms or treatments seem safe to use up to 3 to 4 times during pregnancy.
research Trial Treatment of Androgenetic Alopecia with Oxidizing Agents
Lightly perming scalp hair can lead to new hair growth, potentially treating baldness.
research An Ultrastructural Study of Hair Fiber Damage and Restoration Following Treatment with Permanent Hair Dye
Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
research Effect of Aspartic Acid Intermediate Treatment on Virgin Hair by Permanent Wave
Aspartic acid at 0.75% makes perms more effective and less damaging to hair.
research Chemical Reactions in Curing Treatment for Permanent Hair Straightening Using Thioglycolic and Dithioglycolic Acids
Using both TGA and DTDG in hair straightening reduces hair damage compared to using TGA alone.
research Disorders of the Hair and Scalp
The document concludes that while some hair and scalp disorders can be treated, hair loss from destroyed follicles is permanent, and damaged hair can only regrow naturally.
research Enzymatic Method for Assessing Hair Damage with Reduction and Subsequent Oxidation
Permed hair degrades faster and shows more damage after protease treatment compared to untreated hair.
research A Raman Spectroscopic Investigation of the Mechanism of the Reduction in Hair with Thioglycerol and the Accompanying Disulphide Conformational Changes
Thioglycerol treatment at pH 9.0 with ammonia causes less hair damage and better waving than thioglycolic acid.
research Methods of Hair Straightening: Temporary and Permanent Techniques
Hair straightening changes hair structure and can cause damage if done wrong, but improvements in the methods are expected to continue.
research Hair Straightening: Techniques, Chemicals, and Evolution
Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.
research Environmental and Cosmetic Factors in Hair Loss and Damage
Environmental and cosmetic factors, including heat, chemicals, and sun exposure, can cause hair loss and damage.
