Talk to the hairdresser and pick the right hairstyle for your hair. Length explicitly allow you to make a multi-layer haircut, with a barely noticeable and gradual transitions, where the top layer of hair will gradually become shorter. Firstly, it creates a great visual effect of volume, and secondly, makes the hair easier and the layers are not "fall" down.
Use two types of styling: a special silicone-based to add volume at the roots and easier means of smoothing on the tips. When laying divide the hair into two parts: upper and lower. Twist the top strand and kill the crown from the lower layers of dry, lifting their roots.
Wrong is the popular view that long straight hair can not be bulky. Take a large round brush and start to dry some small strands, pulling them from root to tip, from the position and ending up horizontal. At the roots of direct stream of air from the bottom up is better, and it will be good if, having dried roots, you leave them to cool for 3-4 seconds and then proceed with the rest of the hair. Do the same with the upper part of the hair that was killed.
If your hair is surprisingly quickly lose volume, just dry them after laying again he stooped down. This will give the hair naturally, but at the same time, it will not look sloppy and fluff. Massage your hair at the roots of the hair with your fingertips. By the way, before going to bed, you can tie your hair in a rather loose knot on top and go to sleep with the head (However, if you pull too hard knot - will creases and rumpled appearance). In the morning, the hair will be raised at the roots and slightly wavy.
By the way, to give volume long hair is much better suited styling and fixing sprays, mousses and instead of creams. Hairspray should be easy and non-adhesive hair since it must be applied to the roots, but not on the ends and the rest of the length of hair. To do this, drop your head down and spray paint on roots from quite a distance, gently separating the strands with your fingers. Wait a few seconds in a position such that the locking means is dry, comb and hair brush with frequent teeth.
