I don’t think I really get it then. How many hair growth cycles are there? For 1 growth cycle is it the hair in the whole area or only a smaller percentage of what you see?
Read up on it it’s detailed in many places on this site or google…
There’s basically 3 stages, the general ideal is that stage 1 the hair is in active growth, stage 2 is it’s about to go into rest mode, and stage 3 it’s resting. Only hair in the stage 1 active growth or anagen phase can be treated by the laser. Hair that is in stage 3 for example is dormant and not growing so it can’t be killed. When you let your hair grow, the visible hair there is generally the anagen stage 1. When you go for laser, or wax, you kill all that hair. You’re hair free for several weeks because all the rest of the hair is dormant. It then wakes up and starts to grow as it is now in the anagen phase. There’s less of it because you have killed a bunch from the last session. You then do laser again, kill this hair and repeat. That’s why 6-8 sessions minimum are required to treat all the hair. Read up about it online and you can get all the technical details, this is just the general breakdown.
I recently updated the FAQs. Click on the link below. It’s explained in detail.
At any point, on any area, you have hair in different cycles of growth. One treatment makes all the hair shed, but only the hair in anagen phase of growth is disabled. After shedding, you have a hairfree period and then see new hair grow in. Some of that hair is once again in anagen and some isn’t.
