What is the difference between Japanese Hair Straightening, Chemical Hair Straightening, and Hair Re

JAPANESE HAIR STRAIGHTENING



Japanese Hair Straightening, also known as Thermal Reconditioning in the USA is a method of permanently straightening human hair. This process is different than that of using relaxers to smooth out the hair. The procedure takes four to eight hours, depending on the length and volume of one's hair. Beauty salons in Los Angeles, California charge upwards of $500 USD to perform this procedure. Some salons in Chinatown, New York charge under $200 for the same procedure. In Canada, prices usaully start at $200 CND to $500 CDN. In Korea, the procedure costs 30,000-150,000 won (30-150 USD). In Japan, the procedure costs around 100,000-200,000 Yen (about $90-180)



[edit] Procedure



The process for Japanese hair straightening goes as follows:



The stylist assesses the hair type and condition.



The hair is washed.



If necessary, protein is applied to the hair. There is a small extra charge for this procedure, but it is possible for the customer to end up with less than satisfactory results if the protein is not applied.



Solution #1, which breaks the hair's disulfide bonds, is applied.



The stylist rinses the first solution out of the hair when he or she deems it necessary.



The hair is partially blow dried.



The hair is ironed in small sections with a thermal straight iron.



A second solution, which reforms the broken disulfide bonds, is applied.



Hair is rinsed and conditioned.



Hair is blow dried once more.



The procedure is not particularly effective for tightly curled hair or hair that has already undergone serious chemical treatments. As with any chemical procedure, an experienced technician is essential.



The treatment will also make the hair healthier and shinier. Humidity will not affect the hair as before because the porosity of the hair is changed (hence the smoother feel).



[edit] Care and maintenance



It is advisable to not wash or wet the hair for 24-72 hours after the procedure to ensure that all the disulfide bonds have had time to reform.



The straightening effects are permanent. After several months, it is possible to have the regrowth touched-up.



HAIR RELAXERS



A relaxer is a special type of lotion or creme usually containing a strong alkaline (although it can also contain perm salt) used in the treatment hair with a type of permanent. This treatment relaxes the curls of the recipient, giving it its name. Mostly associated with African-Americans, people of other ethnicities also occasionally get relaxer treatments using a lotion containing ammonium thioglycate.



The alkaline relaxer was actually discovered in the 19th century when African-Americans realized that washing and combing hair with a lye soap helped to straighten it. Proline, manufacturers of Dark and Lovely, officially "invented" the relaxer in 1971. This relaxer consists of a strong alkaline solution such as lye, potash lye or slaked lime, mixed with petroleum jelly, with mineral oil added for consistency. Various emollifiers and conditioners are added in varying degrees.



"No-lye" relaxers contain calcium hydroxide. Calcium hydroxide is a chemical compound with the chemical formula Ca (OH)2. It is a colorless crystal or white powder, and is created when calcium oxide (called lime or quicklime) is slaked with water. A traditional name for calcium hydroxide is slaked lime, or hydrated lime. If heated, calcium hydroxide decomposes into calcium oxide and water. A solution of calcium hydroxide, called limewater, is a medium strength base that reacts violently with acids and attacks many metals in presence of water. Calcium hydroxide can be found in a variety of products, ranging from bowl cleaners, hair removers, and hair relaxers.



A perm relaxer is a thick creme with perm salt or ammonium thioglycate added. The creme is applied to the hair and the creme is left till the maximum time is reached which is between 26-30 mins or until it starts to itch or burn, then its rinsed out and hair is shampooed. A texturizer is an alkaline relaxer with less solution added, to relax the curl slightly. A blowout creme has even less alkaline solution in it and is used by African Americans to create a "soft afro" effect.



One of the reasons that African Americans use relaxers is to make their hair "more manageable". However, African hair is manageable when treated with care and when using the proper tools. African hair is thick, and the purpose of a relaxer is to straighten and relax the hair. The relaxer is applied to the roots and as the hair grows out, the relaxer grows out (much like with hair dye), and the hair begins to return to its original state. Relaxers should be reapplied about every four to eight weeks. They can be done at home or professionally.



In some African American speech communities, relaxers are called "perms".

Chemical hair straightening makes fuzzy, curly, unmanageable hair soft and silky. It is originally developed in Japan for clients who wanted to smooth out their wavy, unruly hair. This chemical service is best done on virgin hair, with excellent results. The service can be performed on previously colored hair, or hair that has had minimal chemical treatments such as bleaching or perm services with good results. It is a permanent service which means your hair will not revert to its original texture. It will be straight until it grows out or is cut off.
