well, write your question by hand. hello, I am a hair stylist, and I have been working for many years. what about your question? In fact, first of all, you have to make sure your hair is healthy. If your hair is really tight, well, it's unhealthy, that means you feel boring, and there are many substations. Well, I suggest you don't do it. It's better if you do more nursing. If the hair is boring, but it can still be curly, then you don't even have to wash it straight. If you straighten it, it won't have much effect. If you want to make your hair look bright, you can only do more nutrition, apply more essential oil and olive oil, and now it absorbs better, especially olive oil. You can do more hair care and laminating of olive business yourself after curly hair. It doesn't work to draw and say. If it's the best, you must look at your hair first. If your hair is really bad, I suggest you do nothing. He can go shopping.
