We strongly recommend the sufficient laser dose is the key point for the success of laser hair therapy from our long term experience in manufacturing professional and home therapy LLLT (low level laser therapy) devices.

The choice to apply the laser module used in the laser pointer is based on the cost and the technology.
(1) The cost of 5 mW laser module (actual power 0.5~4 mW) is < USD 2 /pc purchased from laser modules or laser pointers manufactures.
(2) The technology to produce industrial grade laser module > 50 mW power takes long term effort and budget.
To obtain biostimulation effect to the follicles, the hair laser device must have:
(1) Moderate laser power density to reach the follicles.
Note-(a) A collimated 2 ~ 5 mW laser module with small Laser Beam Spot Size (ex. 0.06 cm²) is very dangerous for human's eyes because of its high power density (33 ~ 83 mW/cm²). And, must be very careful to control the laser dose (treatment time) to avoid hurting the treating tissues include the follicle.
Note-(b) A dispersion 2 ~ 5 mW laser module is applied to the treating tissue from distance (ex. 2 cm),the power density will be too low and can not penetrate the tissue to have the very little effect.
(2) Sufficient emission laser beams to cover the scalp.
(3) Enough delivered laser dose in the reasonable time (15~30 minutes).
(4) The biostimulation effect is decided by laser power density (mW/cm²), NOT by laser power (mW).
We are providing 90 days money back guarantee is based on:
(1) Normally, the hair laser therapy needs 3~6 months to see the result of the hair regrowth. But, the user can easily see the difference after 4~8 treatments like fewer hair loss, not so oily, no more itching etc.
(2) If the laser therapy has no effectiveness for the user's hair loss in 3 months (90 days), it is the waste of user's time and effort to have more laser therapy.
