-Diode: 800-810 nm
-Nd: YAG 1064 nm (neodymium: yttrium-aluminum-garnet)
What are the phases of hair growth - ✔✔anagen, catagen, telogen
Anagen - ✔✔-Active hair growth is occurring
-in early anagen, the follicle is growing and starting to deepen
-Hair is beginning to grow but has not yet reached the surface of the skin
-The mid-late anagen follicle has reached its maximum depth. The hair is fully visible terminal hair on the
surface of the skin.
-The hair shaft bulb is dark or black pigmented and very moist
-Dermal papilla directs and supports hair growth, enclosed by hair matrix
Catagen - ✔✔-Brief transitional stage
-Last only a few days to a few weeks
-Hair folicle seperates from the papilla
-The hair shaft bulb is lighter or brown pigmented and lighter
-Hair folicle shorts 1/3 of its former length
-In late catagen, the thin cord of epidermal cells attaching the dermal papilla to the shrunken hair reacts
upwards, followed by underlyin g hair papilla, which also movesz upwards.
Telogen - ✔✔-Resting or dormant period
-The papilla has detached from the follicle
