Get hair volume for curly and straight hair
Your question is a bit confusing, but it seems that you want your hair to have more volume, and you also want to straighten it. There is no real difference in curly hair and straight hair when it comes to getting the appearance of more volume (if that is your question), except that curly hair naturally seems to have more volume in most cases. In both cases, the hairstyle makes a lot of difference. However, there is no general rule here. You cannot and should not choose a hair style based solely upon maximizing volume. It is advisable that you consider your face shape, your hair type, and your personality too. Your hairdresser is the best person to help you in this area, as he or she can actually see your hair and work with it.
There are some general rules that need to be kept when maximizing hair volume. First of all, don’t grow your hair too long – the longer hair is, the more heavily it hangs and the more difficult it is to give it volume. Of course, very short hair is also difficult to work with, and you need to find your own balance between length and volume. A good compromise is hair that is slightly off your shoulders. Secondly, avoid using conditioner too often, especially if your hair is naturally soft and glossy. Conditioner tends to further weigh down such hair, and may also make it slightly sticky. If you must use conditioner, use a very small amount, and don’t keep it on your hair too long. Better still; use a small amount of leave in conditioner.
There are also shampoos and conditioners available for the special purpose of giving your hair volume, and you can try these products. Volumizers are also available, and the whole point of these products, as the name suggests, is to provide volume to hair. Your hair drying technique can also add volume to your hair. Do not comb your hair when it is wet – instead, allow it to dry naturally. When it is nearly dry, lean forward so your head is upside down, and run your hands through your hair outwards, in an expansive motion. You can comb your hair later, once it is fully dry, and then run your hands through it again.
For hair straightening, the best temporary, home solution is a hair dryer. If you want to permanently straighten your hair, you will just need to get it done by your hairdresser. However, remember that this will reduce volume to some extent. In addition, these hair treatments can be harsh on the hair, and can eventually damage it.
