Home hair coloring saves an immense amount of time and money. However, there is a flip side to this happy story. Store-bought hair dyes are laced with chemicals that harm your health in major ways.
Out of 263 people who used hair dyes, 96% rendered hair unsafe for lactating and pregnant women, 63 reported headaches and 38% reported itching, according to a 2013 study published in the International Journal of Trichology.
Excessive use of chemical hair dyes also weakens hair, causing excessive breakage and hair loss.
Some hair dyes contain gluten and can trigger an adverse allergic reaction in a gluten intolerant person.
Moreover, regular use of chemical hair dyes is positively associated with an increasing risk of bladder cancer, according to a 2005 study published in Public Health Reports.
You can avoid many of these concerns by using natural products without the chemical additives.
