You've already taken the first step by finding a stylist . Your research should include looking at their website, seeing their work, and hopefully communicating with them before the first visit. It's important to have appropriate expectations. There are some things you can do to make your wishes clear. Pictures are always helpful , both of yourself showing positives and negatives,, as well as pictures of styles you like. A discussion is important of course, but pictures can help clarify your wishes. Your stylist will want to know what your daily routine is , as well as what products you use. Remember : Tell the truth ! If your stylist doesn't have accurate information , they can't give you the best results. If you colored your hair six months ago, and your hair is long, you have chemically treated hair, and that affects hair texture. Medications and physical issues can affect your hair as well. Do you have hard water ? Swim in a chlorinated pool? All these things affect hair texture , as well as how your hair may react to products. Don't forget to tell all of this to your stylist.
What condition is your hair in ? This speaks to having those appropriate expectations. If your hair is very dry from many of the possible reasons listed, and you don't want to take off any length, you may never quite get the hydrated curls of your dreams. Despite what hair product commercials tell you, seriously damaged hair can not be fixed with product. Or it may take some time of using good products, putting away those harsh shampoos, brushes and towels to get your hair fully hydrated. Treat those curls with the love they deserve!
Remember : your hair stylist is not a magician or a mind reader. It should be a relationship of give and take. If you are clear about your wishes, and feel you both agree on how to proceed, have fun,and embrace your natural texture!
