Used Feria product on my hair, very happy with the color turnout. I am asthma and take extreme measures to make sure fumes are not inhaled. After coloring, washing and conditing my hair, I went to sleep. At 4:40 I woke up with difficulty breathing. After 15 minutes of trying to stop the asthma attack. my husband called 911, at which time I was turning blue. EMT arrived I was unresponsive and in a mild coma. After using this product I now have to deal with medical issues that could last a life time. All this for beauty... and this was not the first time I had colored my hair or used Loreal products. Something in this particular Feria Sub brand was different.
