Yes, multiple clinical studies show it can stimulate hair follicles, increase hair density by up to 39% in some cases, and reduce shedding by promoting the anagen (growth) phase of hair cycles. It's FDA-cleared for androgenetic alopecia, with results visible after 3–6 months of consistent use.

It uses wavelengths of 630–700 nm (often 650–660 nm) to penetrate the scalp, boosting mitochondrial activity in cells via photobiomodulation. This increases ATP production, enhances blood flow, and nourishes follicles, leading to thicker, healthier hair without heat or damage.

Most experts recommend 3–4 sessions per week, lasting 10–20 minutes each, for at least 16–24 weeks. Consistency is key, similar to a skincare routine, but overdoing it (e.g., daily long sessions) won't accelerate results and may cause mild irritation.

It's generally safe and non-invasive with no downtime, as it doesn't use UV light or heat. Rare side effects include temporary scalp itching, redness, or dryness from increased circulation. Avoid if you have scalp cancer or photosensitivity, and consult a doctor if pregnant.

Initial improvements in scalp health (less itch/buildup) may appear in 4–8 weeks, but fuller, thicker hair typically takes 3–6 months. User stats like 92% reduced shedding in weeks align with studies showing gradual follicle stimulation.

Yes, it pairs well with minoxidil, finasteride, or microneedling for enhanced results by improving absorption and blood flow. It's a great add-on to your routine, but always check with a dermatologist to avoid interactions.
