RLT Hair Growth & Scalp

Red light therapy for hair growth works by delivering low-level laser therapy (LLLT) at 630–660nm wavelengths directly to hair follicles. Clinical studies show LLLT increases follicular blood circulation, extends the anagen (growth) phase and reduces hair shedding caused by androgenetic alopecia and stress-related hair loss.

ZackFitness stocks three types of scalp devices: hands-free therapy caps for whole-scalp coverage, infrared scalp helmets for deeper follicle penetration at 830nm, and scalp massage combs that combine 630nm red light with mechanical stimulation for daily use.

Recommended use: 10–20 minutes per session, 3–5 times per week. Most users report visible improvement in hair density within 8–16 weeks of consistent use.
