Oxygen Laser Therapy (OLT) is an FDA-approved, non-surgical hair regrowth treatment. It uses low-level laser light at 655nm — a cold beam that produces no heat — combined with oxygen infusion. The laser penetrates the scalp and reaches the mitochondria inside dormant hair follicle cells. It boosts ATP energy production inside those cells, effectively waking them up. This reactivates follicles that have slipped into the resting (telogen) phase prematurely, extends the active growth (anagen) phase of each hair strand and improves blood circulation to deliver more oxygen and nutrients to the follicle root. The result is reduced shedding, stronger existing strands and gradual regrowth over 3–6 months. It is completely painless and requires no recovery time.

OLT is completely painless. The laser is a cold beam — it produces no heat, no tingling, no burning and no sensation of any kind on the scalp. You simply sit comfortably under the OLT device or helmet for 30–45 minutes. Most patients describe sessions as relaxing — some use the time to read or listen to music. No anaesthesia is needed. You walk out immediately after the session and can resume your normal routine — including washing your hair — right away. There is no redness, swelling or after-effect on the scalp.

Results come in stages. Most patients notice a reduction in daily hair shedding within 4–6 weeks — this is the first sign that follicles are responding. Visible improvement in hair thickness and density typically follows from the 3rd month onwards. A full initial course is usually 12–20 sessions delivered fortnightly — so roughly 6–10 months. After that, monthly or bi-monthly maintenance sessions keep the results going. The exact number of sessions for your case is determined at your trichoscopy assessment. Your dermatologist will give you a clear, personalised timeline at your first visit.

Yes — OLT is equally effective for men and women. For men, it is particularly useful for androgenetic alopecia (male pattern baldness) from stage 2 onwards — where the hairline is receding or the crown is thinning. For women, it works well for diffuse thinning, postpartum hair loss, stress-related shedding and hormonal hair loss. It is one of the few non-hormonal, drug-free treatments with proven clinical benefit for both sexes. Your dermatologist will review your hair loss pattern at trichoscopy and confirm whether your specific case is a good fit for OLT.

Yes — and the combination often produces better results than either treatment alone. PRP delivers growth factors (PDGF, VEGF, EGF) that stimulate follicle regeneration from within. OLT enhances the scalp environment by improving blood flow and oxygen delivery — making the scalp more receptive to PRP. Scalp mesotherapy delivers targeted nutrients and growth factors directly into the dermis. Together with OLT, these create a comprehensive approach that addresses follicle stimulation, scalp nutrition and blood supply simultaneously. Your dermatologist will recommend the right combination based on your trichoscopy findings and hair loss stage.

OLT is a safe, FDA-approved treatment with no known adverse side effects when performed by a certified dermatologist. The 655nm cold laser does not damage scalp tissue, does not burn skin and carries no ionising radiation risk. It is non-invasive and has been used globally on millions of patients without systemic side effects. However, it is not recommended for people who are pregnant, currently taking photosensitising medications, have active scalp infections or open wounds, or have a history of skin cancer. All of these factors are reviewed during your consultation at Maynee before any treatment begins.

OLT works best when hair follicles are still alive but dormant or weakened. In areas of the scalp where follicles have been fully inactive for many years and the skin has become smooth and shiny (indicating follicle death), OLT alone is unlikely to produce significant regrowth — because there are no follicles to stimulate. For advanced cases, a hair transplant or combined approach is typically more appropriate. Trichoscopy at Maynee determines whether your remaining follicles are still viable — so you get an honest assessment of what OLT can realistically achieve for your specific pattern of hair loss.

OLT produces lasting improvements in scalp health and follicle activity during the treatment period. However, the underlying causes of hair loss — genetics, hormones, ageing — continue to act on the scalp even after treatment. This means ongoing maintenance sessions are important to sustain results. After completing the initial course, most patients continue with monthly or bi-monthly maintenance OLT sessions. This keeps follicle stimulation active and prevents regression. Think of it similarly to maintaining a treatment for a chronic condition — the therapy works while it is applied consistently. Your dermatologist at Maynee will discuss the right long-term maintenance plan at the end of your initial course.

Before each session: wash your hair with a mild, sulphate-free shampoo on the morning of your visit. Do not apply hair oil, serum, dry shampoo or any styling product to the scalp before treatment — these can block laser penetration. Inform your dermatologist if you have started any new medication since your last visit. After each session: you can wash your hair, exercise and go about your day immediately — there is no downtime. Avoid harsh chemical treatments (bleaching, straightening or perming) for 48 hours. Follow your prescribed home-care shampoo and supplement protocol consistently between sessions — this directly supports the clinical sessions and affects your overall results.

The cost of Oxygen Laser Therapy at Maynee in Chennai depends on the total number of sessions in your personalised programme, whether it is combined with PRP or scalp mesotherapy, and the stage of your hair loss. Because every programme is custom-designed after a trichoscopy assessment, we do not publish flat-rate pricing that applies to everyone regardless of their condition. A complete, fully transparent cost breakdown is provided at your first consultation — after your dermatologist has assessed your scalp and built your treatment plan. There are no hidden charges and no pressure to commit on the day.
