Your call
Which one fits you
Pick the iRestore Essential if
- You want to try a helmet routine without a big outlay
- You like the safety net of a year-long return window
- Your thinning is early and you want something simple
The catch: Fewer than half the light sources of the Professional for $300 less, and the same 25-minute sessions. If you can stretch to $799, the Professional is better value per diode.
Pick the Theradome EVO LH40 if
- You want a cordless helmet for under $500
- You want to try light therapy cheaply
- You do not mind four short sessions a week
The catch: 40 lasers is the second-lowest count on our list, and the routine doubles to four sessions a week to make up for it.
