  • How many times a week and how long is each use?

    Use it every other day for 30 minutes. When your treatment session is complete, the Revitalizer will automatically shut off.
    If you are going to use it everyday use it for shorter treatments more frequently, wear your Revitalizer cap every day for 5-10 minutes. Set a timer to remind you when to shut off your device manually.

  • how long does it take to regrow very thin or nearly bald headed?

    Hair goes through a growth cycle, from anagen (growing), to catagen (resting), to telogen (shedding).  Depending on where your hair follicles are in the growth cycle.


    The timespan of the Hair Growth Cycle

    • The anagen phase constitutes about 90% (1000 days or more) of the growth cycle.
    • The catagen phase (10 days) and telogen phase (100 days) constitute only 10% of the hair growth cycle.
    • During the catagen and telogen phase of the hair growth cycle, as hairs are at the shedding and rest-from-growth period, no bald spots are shown as hairs are randomly distributed over the scalp.


    LLLT (low light laser therapy) has been proven in clinical results to reverse the thinning process and increased density and fullness of hair.


    Using laser therapy (along with regrowth methods like HairClub’s EXT) most people see the best results in 4-6 months.  This allows for hair to process through the lifecycle.

Caveat Emptor/buyer beware

Don't know what the results will be as only used it for 2 weeks, no visible results yet. Can say the batteries do need recharged much more frequently than advertised, after every second use and not after 4-5 uses as stated
