Protein correction generally does not harm the hair, but the program is not a medical program and cannot treat hair disorders, and it may also cause irritation to the scalp. Protein Correction focuses on applying a protein agent to the hair, which is then applied to the hair by means of high temperature and heat, thus leaving the hair in a smooth, silky condition. Protein correction uses protein agents that incorporate soluble and stable protein substances. Protein Correction is a method of hair maintenance that mainly serves to alleviate dryness and soften the hair. However, in the process of use, the open area of the scalp hair follicle may come into contact with part of the protein agent, so it is possible that Protein Correction may cause irritation to the scalp, which is prone to cause discomfort. Protein Corrective Hair is not a medical program and has no therapeutic effect on hair disorders, and blind use of Protein Corrective Hair may lead to contact dermatitis and so on. It is recommended that patients with hair diseases go to regular hospitals for hair follicle testing to determine the number of scalp hair follicles and the state of health, etc., and standardize the treatment under the guidance of the doctor.
