Sooo...after about 10 years with absolutely no chemicals in my hair I finally took the plunge and attempted to get some highlights. I went to a Devachan type of salon...due to the fact that i am a regular henna user the color didn't take! I can barely see very very dull highlights. However, my hair notice the i have dry, shedding hair but NO HIGHLIGHTS!! I am scheduled to go back and use a "stronger" chemical to achieve the color but after seeing my beautiful healthy hair shed continuosly and constantly feeling dry I think I'm ready to go back to henna! I miss the benefits of the natural, messy, smelly, no color really having dye! lol...who knew...Lesson: If it ain't broke don't try to fix it!! :D
