If you are reading this, most likely you suspect that you have had an allergic reaction to your hair dye. Maybe you have never had an issue before, but now it has become an issue. It happened to me. I want to share the information I have found and make everyone aware that it can happen. Aging has a lot to do with this. Yes, you are growing older and as we age our bodies change. Every cell in our body changes every 7 years. Things we eat or cosmetics we have used for years with no adverse reaction to, as we age we can become allergic to later on in life. My dermatologist told me that as we age our skin becomes thinner. Do you know as we age, we shrink? Yes, so that means our skin can absorb things a lot sooner than before, allowing things to get into our bodies quicker.
