LLLT — Laser therapy
Occasionally the desired results are not achievable due to lack of donor supply. In such cases, we discuss the best possible outcomes achievable and any ways to optimise the native hair growth.,Sometimes a hair transplant is not suitable for you at this time, but requires some preliminary treatments to improve the quality of the native hairs or to stabilise the hair loss and reverse any miniaturised follicles as much as possible. There are a range of treatments that can help with this, namely the following:
Low-Level Laser Therapy (LLLT), also called photobiomodulation, uses red or near-infrared light to stimulate hair follicles. The light is absorbed by the cells of the follicle, supporting their energy production and prolonging the active growth phase. It is delivered through devices such as laser caps, helmets and combs, or with in-clinic machines, and is painless and non-invasive.
How it works
- Photobiomodulation: Light around 650 nm is absorbed by cells, releasing nitric oxide and modulating reactive oxygen species, which supports cellular energy (ATP).
- Follicle support: This is thought to keep follicles in the growth (anagen) phase for longer and to improve scalp blood flow.
- At home or in clinic: Caps and combs allow regular home use, while clinics may offer higher-powered panels.
What the evidence shows
- LLLT is the one device class with FDA clearance for androgenetic alopecia — first cleared in 2007 for men and extended to women in 2011.
- Randomised trials and large real-world studies report meaningful increases in terminal hair count and density, with a good safety profile.
- It improves density in thinning areas but does not regrow hair on a fully bald scalp.
What to expect
- Consistency is essential: most devices are used several times a week, for 15–30 minutes per session.
- Visible improvement — less shedding, thicker strands — typically appears after 3–6 months of regular use.
- Many people continue LLLT long-term as part of a maintenance routine.
Who it suits
- Men and women with pattern thinning or general reduced density who prefer a needle-free, painless option.
- Works well alongside PRP, medication or a hair transplant.
LLLT is most effective when it is used consistently and as part of a wider, doctor-guided plan — your clinician can advise whether it fits your hair-loss pattern and goals.
