HFCI = Hair Follicle Catagen Induction

Preserved with Leucidal Liquid - Water Soluble

Hair undergoes a growth pattern unique for mammalian tissue. Hair follicles (HF) cycle through what is typi­cally described as three distinct phases, although many researchers are careful to subdivide them further. Hair growth activity starts in the anagen phase where the hair follicle functions as a factory devoted to producing hair. The hair produced at this stage is imparted with color by the implantation of melanin directly from the melanocytes to the hair cortical cells.

After a set period, depending on the individual as well as the physical location of the HF on the body, the anagen phase ceases and catagen is initiated. Catagen is characterized by the abrupt cessation of growth and pigmenta­tion of the hair fiber. At this time, there is also a rapid and intense involution of the HF. Catagen is followed by the telogen phase. Typically considered to be a resting phase where the HF prepares for the next anagen phase, some researchers believe that telogen is responsible for regulating the growth cycle, function like a brake slow­ing the onset of the anagen phase.
