For customers with wavy hair we also have suitable hair extensions. These are wavy hair strands with a length of 55 cm (22"). In wavy condition this hair is about 48-50 cm long. The strands are provided with keratin inserts and are attached to the hair by the warming method (connector iron) or cold method (ultrasonic). For normal self-hairs you need about 100-125 strands, with dense or very dense hair - about 150-225 strands. It is important to maintain, this hair extension should be never smoothed. Because the smoothness of the wave is gradually destroyed and the hair remains permanently smooth or with a light natural wave. If you want to wear your hair smoothly, sometimes wavy, you prefer to take straight extensions and use the curling iron if necessary. We also have matching curling irons and straighteners. If you have chosen wavy extensions, do not wash them with smooth shampoos. Please use our care kit, it fits perfectly with smooth and wavy hair.
