Laser therapy can compound the hair-growth effects of medications and help stimulate new growth. It also helps promote healing after surgical hair restoration treatments. There are a variety of FDA-approved Low-Level Laser Therapy (LLLT) devices available, including helmets, hats, and combs that can be used at home.
Boosts Blood Flow
The light in laser treatment for hair loss therapy stimulates the blood flow in the skin. This increases the delivery of nutrients to your hair follicles and helps to prevent hair loss. It also stimulates hair follicles into an anagen (growth) phase. You can expect to see results in about a month with regular sessions. Laser hair treatment can help you stop thinning hair and encourage new growth without the side effects that often come with medication. It’s a safe option for most people, but it’s best to talk to your doctor before deciding whether or not this is the right option for you. Before starting the treatment, wearing protective goggles is essential to protect your eyes. Your doctor will place a small laser instrument against your scalp. A cooling device or gel may be used on the tip of the instrument to help prevent any discomfort or pain that you might feel. The light emitted from the laser instrument targets chromophore molecules in your hair follicles. This causes them to release adenosine triphosphate, promoting cellular growth. It also boosts nitric oxide production, stimulating circulation and delivering oxygen to your hair follicles. This also reduces the build-up of dihydrotestosterone (DHT) that blocks hair growth in some people. The combination of the increased blood flow and the cellular stimulation helps to restore your entire head of hair.
Strengthens Hair Follicles
Various treatments are available to help slow hair loss and encourage new growth. Many involve drugs that block the hormones responsible for thinning hair; others improve blood flow to specific scalp regions. Laser therapy is another option that can improve the supply of nutrients to hair follicles by stimulating them. This is a non-invasive treatment that can be used at home. Medical-grade lasers deliver safe, low-level light energy to the scalp. This energy is absorbed by the pigment in the hair and converted to heat. The increase in temperature triggers microcirculation and increases the number of blood vessels that provide a steady stream of nutrients to the hair follicles. This is also believed to stimulate new hair growth by triggering the production of cellular hormones. This process is called photobiostimulation. The exact process stimulates plants to grow when exposed to light. This light therapy can help promote healthy follicles, leading to thicker and fuller hair. Researchers have found that LLLT can induce anagen-phase hair growth in humans and mice. The effects were seen in both men and women experiencing thinning or baldness. It was also effective in preventing alopecia areata and increasing regrowth and density.
Stimulates Hair Growth
The lasers used in hair removal produce highly concentrated beams of light that penetrate the pigment in your hair and convert it to heat, damaging the follicle and preventing future growth. The laser therapy that promotes hair growth differs, using low-level waves of light to stimulate your scalp’s follicles without harming your skin. The exact process is unclear, but it is believed that the light waves stimulate the production of nitric oxide in your cells, which results in increased blood flow or vascularisation to your scalp and hair follicles. In addition, the treatment is thought to stimulate telogen hair follicles to reenter the anagen phase and increase cell proliferation rates in follicles in the anagen phase. LLLT can be used as a standalone solution for hair loss or combined with treatments for even more effective results. Many use it to add to other hair growth products, such as over-the-counter shampoos and thickening serums. It can also be paired with a scalp massage to boost your treatment’s effectiveness further. To get the most out of your LLLT sessions, it is recommended that you make regular appointments over a long period (typically more than a year). You will be exposed to laser light for about 15 minutes each during these sessions.
Reduces Hair Loss
Laser therapy increases your hair follicles’ ability to regenerate new strands. This rehabilitative effect on your hair and scalp is known as photo-bio-stimulation, and it can significantly improve the tensile strength of hair strands. It also helps to prevent how to treat hair loss by reducing the production of dihydrotestosterone (DHT), which can inhibit hair growth. Unlike the lasers used in surgery to cut or cauterize tissue, low-level laser light does not burn or damage the skin. Instead, it stimulates the release of nitric oxide, which increases blood flow to your scalp, a process called vascularisation. This allows nutrients and oxygen to reach your hair follicles and promotes the regeneration of the follicles and their stem cells. It can be used alone or paired with PRP (Platelet Rich Plasma) treatments for even better results. You will need to undergo laser therapy sessions at least two or three times a week for several months to see significant improvement in your hair. It would be best to pair it with other treatments that increase blood circulation, such as a scalp massage. Consider taking hair supplements high in protein and vitamin D, as these will help strengthen your hair. The most important thing is to keep your treatments consistent.
