Laser Hair Regrowth

Laser hair regrowth, or low-level laser therapy (LLLT), uses low-intensity light on the scalp to stimulate weakening hair follicles. It is non-surgical, usually causes no discomfort, and is used for early-stage pattern hair loss and thinning, usually alongside medical treatment, PRP or GFC rather than on its own.

Evidence suggests it can give a modest improvement in hair density for some people. It does not regrow hair where follicles have been lost, and results vary between individuals.

What is laser hair regrowth therapy?

LLLT uses light at wavelengths and power levels that do not heat or damage the skin. It is thought to increase the activity of cells in the follicle and help more hairs stay in their growth phase.

How does laser hair regrowth work?

• May encourage resting follicles to re-enter the growth phase
• May improve the thickness of existing hair
• Needs regular sessions over several months, and the benefit fades if treatment stops

What results can you expect?

• Non-surgical, with no downtime; side effects are uncommon and mild, such as temporary scalp irritation or itching
• Any change is usually assessed after three to six months
• Works best for early-stage thinning, and alongside other treatments

Who can benefit from laser hair regrowth?

• Men and women with hair thinning and mild to moderate hair loss
• People with androgenetic alopecia (male and female pattern hair loss)
• People looking for a non-surgical, pain-free option to add to medical treatment
• Patients having PRP or GFC therapy
• Patients after a hair transplant, to support the native hair

How does laser hair regrowth compare with PRP and hair transplant?

• Laser hair regrowth – non-surgical, usually without discomfort, and no downtime; for early hair loss and thinning; any change is usually assessed at 3–6 months.
• PRP therapy – non-surgical injections with mild discomfort; for thinning and moderate hair loss; any change is usually assessed at 3–6 months.
• Hair transplant – surgical, with some discomfort and a recovery period; for established bald areas with enough donor hair; the result develops over 6–12 months.
