what is lanthionization
During a chemical relaxing procedure of a hydroxide relaxer a process called lanthionization occurs, which is the breaking of a disulfide bonds to alter the curl pattern of the hair. During this process the curl pattern is loosened or relaxed.
How do you use a hydroxide relaxer?
The pH of a hydroxide relaxer is typically 13 or higher which is considered a high alkaline concentration. Therefore an acid-balanced shampoo must be used to …
What type of hydroxide relaxer is known as a lye relaxer?
The main active ingredient in a Lye Relaxer is Sodium Hydroxide (NaOH). Sodium Hydroxide relaxers are very effective in breaking down the hair's bonds (straightening the hair) quickly. Because it processes quickly it is also the most commonly used relaxers by professionals.
Do you shampoo before a hydroxide relaxer?
Avoid irritation do not shampoo before hydroxide relaxer.
What is the difference between no base and no lye relaxers?
No base means no mixing of a base chemical to activate the relaxer, you can use it right out of the jar. These usually contain lye (sodium hydroxide) but you can find very few without it. No lye means it straightens without sodium hydroxide so its gentler on your hair and scalp.

What’s the difference between Thio and hydroxide relaxers?
Thio relaxers differ from hydroxide relaxers in a few ways. The pH of thio relaxers is typically around 10 whereas the pH of hydroxide relaxers is approximately 13. Also, an oxidizing agent like hydrogen peroxide or sodium bromate is used to neutralize thio relaxers.
What are the three types of relaxer?
There are three types of relaxers; sodium hydroxide, calcium hydroxide and ammonium thioglycolate. Sodium hydroxide relaxers are commonly called lye relaxers. Lye relaxers can be used on wavy, curly or coily hair.
What are Thio neutralizers?
first functions of permanet waving (thio) neutralization is the deactivation or nuetralization of any waving lotion that remains in the hair after processing and rinsing. Thio neutralization rebuilds the disulfide Bonds by removing a hydrogen.
What is the safest hair relaxer?

What is a Thio relaxer?
Thio relaxers break the disulfide bonds in hair, similar to the permanent waving process. When enough of the disulfide bonds in the hair are broken, the relaxer is rinsed from the hair and the hair is towel dried. After towel drying, a neutralizer of some sort is applied to the hair.
What is a metal hydroxide relaxer?
Metal hydroxide relaxers are ionic compounds formed by a metal, sodium (Na), potassium (K), or lithium (Li), which is combined with oxygen (O) and hydro- gen (H). Metal hydroxide relaxers include sodium hydroxide (NaOH), potassium hydroxide (KOH), and lithium hydroxide (LiOH).
What are the four metal hydroxide relaxers?
Hydroxide relaxer types include sodium hydroxide, potassium hydroxide, lithium hydroxide and guanidine hydroxide. These relaxers can be marketed as base and no base relaxers.
