Hair Growth Cycle

---

• Active Growth
• Producing new cells
• The growing phase lasts two to seven years and determines the length of our hair.

• Hair follicle stops growing
• The hair follicle is detaching slowly  
• This stage lasts about ten days. The hair follicle shrinks and detaches from the dermal papilla. 

• Follicle rest
•  Prepares for the next cycle 
• The resting phase lasts around three months. Around 10-15% of hairs are in this phase. Whilst the old hair is resting, a new hair begins the growth phase. 

• Cycle starts over 
• The Exogen represents the period from when a resting hair reaches its terminal position in the follicle to when it finally detaches. The resting hair is gradually loosened resulting in shedding of the hair. 

             1.   The area is cooled to protect upper levels of the skin. 

             2.   Laser beams penetrate skin which is absorbed by the hair shaft and converted to heat. 

             3.   Heat effectively damages hair follicles, significantly impeding ability to re-grow.
