Hair straightening is a common practice among women with curly hair. The hair for this procedure is straightened with the help of heat or chemical techniques. Also known as hair relaxing or lanthionization, it is a chemical process through which extremely curly hair is straightened with the use of metal hydroxides, such as sodium, lithium, potassium, or hydroxide, to change the properties of the hair to lanthionine. However, chemical relaxing can be easily achieved through lye-based, lye-free, ammonium thioglycolate, or bisulfate creams. Hair straightening chemicals are all well known irritants. It is for this reason that a petrolatum cream must be applied as a base to the scalp and hairline. Also, one should only shampoo and condition their hair after the procedure and not before it. Hair straightening is a delicate procedure and must be performed by experts only, preferably in salons.
