Will This Work for Me?
Worried that laser hair therapy only works for certain skin tones? Don’t be!
Kiierr’s laser cap is designed to support hair regrowth across all skin types. While clinical studies have historically focused on lighter skin tones, low-level laser therapy (LLLT) is just as effective - if not more so - for darker skin. Kiierr’s advanced laser technology delivers the optimal energy to stimulate hair follicles, regardless of your complexion.
