Hair regrowth is variable for different areas and individuals

William Groff, DO answers: Length of time between laser hair treatments

A few laser practioners I have been to have given me conflicting advice about the length of time I should wait between treatments. Some say 4-5 weeks is the ideal period while others have indicated 7-8 weeks is much better if one is to target a greater proportion of hair in the right growth phase. What is your view on the ideal length of time that one should wait between treatments?

In general, the best way to approach this topic is to use the regrowth of hair in the treated area as your guide... in other words, when a significant percentage of the hair starts growing back, return for the next treatment. 

It could be as short as 4 weeks on the face, and as long as 12 weeks for the legs or more. 

I hope this helps.  Take care.
