Stage 1  
<br />The first 4 times, use it once every two weeks. The hair will not fall down                          immediately after use. You will smell a little burning of the hair. The first time                    use click one, use click two after two weeks. After 3 or 4 times, you will see                      most hair had removed.
<br /> 
<br />Stage 2  
<br />The 5th-7th usage, use it once per month.
<br />The hair will grow very slow at this stage.
<br /> 
<br />Stage 3  
<br />The 8th-15th usage, use it every three months.
<br />Only very few new hair will grow.
<br /> 
<br />Stage 4 
<br />Congrats. Permanently removed of the hair.
<br /> 
<br />P.S  Of course the stage depend on different situation, some may be faster, some maybe slower.
