Description

The present invention, LFO waveforms agent second agent, and a waving agent.

In recent years, high-temperature regions such as Southeast Asia have become important for the wave agent market.

The evaluation results are shown in Table 1 or 2.

Layer separation is “◎” is “not recognized even after 3 months”, “○” is “accepted after 1 to 3 months”, “△” is “after 2 weeks to 1 month, “Recognized” and “x” are “recognized before 2 weeks”.
<Wave agent performance evaluation test>

  First, a healthy hair bundle (10 g, length 25 cm) was wetted with water and wound with paper and a rod (diameter 1.5 cm). Next, the hair bundle was applied with the first wave agent (3 ml), left still (room temperature, 15 minutes), and washed with water. Subsequently, this hair bundle was repeatedly subjected to a series of hair treatments of application of the second wave agent (3 ml) and standing (room temperature, 10 minutes) twice. The hair bundle was removed from the rod so as not to break the wave, rinsed, and dried with a dryer.
