The technique is: Learn to work your hair strand by strand, with the right products to boost the volume at the roots and shape curve to tip. You just need a powerful dryer, round brush ...! And a little practice and patience.
1. For your hair does not lose its natural shine, stick to absorb moisture with a towel, do not rub!
2. Apply a product to boost the volume on the roots of your hair and then aim the dryer directly into this area, to allow penetration.
3. Remove the upper layers to dry first they are lower, smoothed with a round brush. Upon reaching the tip, rotate the brush to curve outward.
