Which laser cap should I choose?
We have 4 laser cap options: 148 Pro, 272 Premier, 272 MD Elite, and 302 MD Ultra Flex. Choosing the right cap depends on your specific needs. For early stages of hair loss or those on a budget who are okay with slower, steadier results, the 148 Pro is ideal. If you’re seeking more significant and quicker regrowth, the 272 Premier is our bestseller.
For larger head sizes or extensive coverage, the 272 MD Elite is perfect. Lastly, the 302 MD Ultra Flex offers the fastest results and superior comfort. Ideal for severe hair loss, this model also offers a soft flex fit for maximum comfort.
How long will it take to see results?
Results vary, but most users see noticeable improvements within 6-12 weeks. We’re so confident in our product that we offer a 7-month growth guarantee—if you don’t see results, you can return the cap!
