Both of Theradome’s helmets, the PRO LH80 and the EVO LH40, are made with medical grade lasers which emit 680 nanometer wavelengths, targeting the stem cells in the base of the hair follicles for maximum stimulation and growth. The decision of which helmet to purchase will come down to a personal preference between cost and desired use time.
The PRO LH80 has 80 lasers while the EVO LH40 has 40, and that means you will get the same results by using the PRO LH80 2X per week that you will from using the EVO LH40 4X per week, for twenty minutes a session. Since we have many users who wear their helmets everyday with absolutely no side effects (and even twice a day for a total of 14X per week!), you can achieve results twice as quickly using the PRO LH80 everyday as you can using the EVO LH40 for the same number of treatments.
If you choose to wear your helmet more than once per day, we just recommend that you wait several hours in between treatments.
Both the PRO LH80 and EVO LH40 have full scalp coverage, with lasers reaching the top, back, sides, crown and temples. The PRO LH80, with a higher number of lasers, will initially reach more hair follicles in each treatment, before the laser energy begins to scatter and be absorbed, similar to water hitting a sponge. While each helmet covers the full scalp, it just takes more treatments with the EVO LH40 to achieve the same amount of follicle stimulation as with the PRO LH80. Here’s some more information on their similarities and differences:
