Chemical Hair Treatments Post Cancer
How safe the chemicals treatments (like keratin, cysteine) are on hair after the person has recovered from ailments like Cancer (which makes the patient to lose his/her hair during the treatment).
Chemicals like formaldehyde creams are applied to the hair and the hair is then heated with hot irons. The combination of chemicals like formaldehyde, heat, compression is not good for even normal hair. It is only worse for people already suffering from cancer and whose scalp and tissues are already made quite sensitive from the process of chemotherapy and radiation.
Even Brazilian blowouts that claim they have no formaldehyde have methylene glycol which when heated produces formaldehyde.
Medically we do not recommend any treatments to do with chemicals or heat . we do not know the effect of such treatments and what bearing they have in the long run and even in case of relapse there should be no ambiguity to the patient that his condition could have been prevented.
SLS free shampoos, minimal heat styling and avoiding chemical processing of hair are definitely to hair that has undergone a lot of trauma. Deep conditioning treatments, oil massages will also help improve condition of the hair
