If you have a curly mane, then your styling options are limited. The best option for you may be to sport a long blunt. This will help you control your split ends and will also keep your hair under control. The shorter you cut your hair, the curlier it will get. So if you keep it a bit long, the curls will relax. However if you have a small face with sharp features, then you can sport a smart look with short hair.
If you have tight curls, then you must avoid razor cutting as well as shears thinning. Thinning crushes your hair ends and razors encourage split ends. If you have very thick hair then you must get your hair done in order to remove the volume and make it more manageable. If your curls are not too well defined then you can go for long layers. It gives a stunning effect if you dry such hair naturally or at max blow dry.
You must consult a good stylist for styling your hair. They can guide you on which haircut will suit you best. You must also confide in him regarding the time and money you are willing to invest in grooming and maintaining your hair. You must be totally honest. Only then will he be in a position to guide you in a way that will benefit you.
