Hello, Im a new member I am also a cosmetologist. Yes need to go a professional for they can evaluate you hair and see what it needs to process the color safely. For they they look at the type of hair you have if needs to be hydrated before coloring which will prevent breaking. They will also help you pick out o color that is right for your skin tone. When you pick professional hairdresser, talk friends, co-workers that you noticed have had hair color done that is attractive on them for word of mouth is the way to find your hairdresser.
