smoothing hair


Are you suffering from your curly hair?
Would you like to have the straight hair and in a satisfactory condition ?
You can use hair relaxing ,so your hair would be set into almost any style. The basic products that are used in chemical hair relaxing are a chemical hair relaxer, a neutralizer, a protein-rich moisturizer to stabilize the hair, and a petroleum cream, which is used as a protective base to protect the client’s scalp during the sodium hydroxide chemical straightening process.
The two types for this goal are sodium hydroxide,which does not need per_shampooing and ammonium thioglycolate ,which needs pre shampooing.Both softens and swells hair fibers when the solution penetrate into the cortical layerthe cross-bonds between sulfur and hydrogen are broken and when we use brush or handsin smoothing the hair and distributing the chemical straightens the softened hair.
On the other hand we use the neutralizer which stops the action of any chemical relaxer that
remain in the hair after rinsingThe neutralizer for a thio typerelaxer re-forms the cysteine (sulfur) cross-bonds in their newposition and rehardens the hair.All chemical hair relaxing consist of this three basic steps:
Processing: when it is applied,hair brgins to soften and chemical penetrate to loosen and relax the natural curl.
Neutralizing:The chemical relaxer is rinsed by warm water and follow bya built-in shampoo neutralizer.
Conditioning: Depending on the client’s needs, the conditioner may be part of aseries of hair
treatments, or it may be applied to the hair after the relaxing treatment.
