In the late 1970s, researchers institute that several chemicals in hair dye, such as 4-MMPD and 2,4-toluenediamine, increased cancer risk in lab animals, so manufacturers removed them from their products. At present, there is picayune evidence for a link between the 2.
Some inquiry does suggest a possible link between hair dye utilise and bladder cancer. Several studies have shown that salon stylists who dye clients' hair, and thus are exposed to hair dye on a regular footing, have "a small-scale only fairly consistent increased risk of float cancer risk" compared with the full general public, according to the American Cancer Lodge (ACS). Inquiry has found no such link between personal hair dye employ and bladder cancer, according to a 2008 meta-assay of 12 studies in the journal Cancer Causes & Control.
Studies investigating the relationship between hair dye and breast cancer and blood-related cancers have found mixed results and no conclusive evidence to suggest a link. At that place is not plenty information bachelor for other types of cancers, the ACS reported.
"Based on the research, it'due south actually not clear how much individual personal hair dye use might raise cancer adventure, if at all," Khetarpal told Alive Science. "Nigh of the studies did not find a strong link." The International Bureau for Inquiry on Cancer, a subsection of the Earth Health Organisation, has not classified hair dye in relation to cancer gamble, stating that there is not plenty evidence.
The other major health business concern about hair dye is that some people are allergic to its ingredients, Khetarpal said.

People who are allergic to this chemical may feel itchiness, skin redness, eczema and hives, co-ordinate to a 2018 study published in the Annals of Dermatology. When using a pilus dye for the first fourth dimension or when switching to a new brand, do a patch test kickoff by dabbing a bit of dye behind your ear and waiting 48 hours to meet if y'all develop an allergic reaction, Khetarpal said.
Hair dye tin can also irritate pare if applied incorrectly. So, here are some tips: to protect your easily, always wear gloves while applying hair dye; permanent and semi-permanent dyes can crusade a chemical burn down on the scalp if left on for also long, and so use a temporary dye the kickoff time you dye your hair at home to practice the technique, Khetarpal recommended.
Moreover, don't dye your eyebrows because the hair is too thin. Never mix dyes, so if you lot desire a custom color, it'due south best to visit a salon. Otherwise, there is no safety difference between boxed dyes and salon hair dyes, Khetarpal said.
