Kiierr® makes three FDA-cleared laser hair growth caps that all use a baseball-cap form factor — the most discreet option in the LLLT category. For GLP-1 users dealing with the rapid-weight-loss shedding affecting 40-60% on Ozempic®, Wegovy®, Mounjaro®, or Zepbound®, Kiierr's cap design lets you wear the treatment during normal daily activities — walking, working from home, watching TV. This guide breaks down the three Kiierr models.
