<p>Laser hair growth treatment uses low-level lasers to emit light energy into the scalp tissues and feed the weak hair follicles. Once the follicles absorb the energy, the body triggers biochemical reactions (similar to photosynthesis in plants) that support the natural hair growth process. This procedure is called low-level laser therapy (LLLT), and its hair-stimulating effects were first discovered by <a href="https://en.wikipedia.org/wiki/Endre_Mester">Endre Mester</a> in 1967.</p>

What is laser hair growth treatment?

<p>The potential of laser treatment to increase hair growth is primarily correlated with the effects of light energy on stimulating cellular activity in hair follicles. According to research, laser treatment has multiple mechanisms to stimulate hair growth. These include increasing blood flow, reactivating dormant follicles, and reducing inflammation.</p><p>Learn more on <a href="https://womenconcepts.com/haircare/hair-growth/laser-hair-growth-treatment">Women's Concepts</a>.</p>

Besides, LLLT increases the production of ATP (adenosine triphosphate), which delivers energy to the hair follicles and stimulates their cellular functions. This is huge news since poor blood flow is often the cause of premature hair shedding.<sup dir="ltr"><a href="https://womensconcepts.com/haircare/hair-growth/laser-hair-growth-treatment#footnotes" dir="ltr">[4]</a></sup></p><h3>Reactivates hair follicles</h3><p dir="ltr">Low-level laser therapy is also assumed to reactivate dormant follicles. Specifically, it pushes the resting follicles to enter the anagen phase, in which the hair is actively growing. In normal hair cycling, about 90% of follicles are in the anagen phase. However, those suffering from hereditary hair loss usually have a reduced duration of the anagen phase. This means the time the hair actively grows is significantly lower.<sup dir="ltr"><a href="https://womensconcepts.com/haircare/hair-growth/laser-hair-growth-treatment#footnotes" dir="ltr">[5]</a></sup> According to studies, light therapy can prolong the anagen phase’s duration and prevents the premature entry of hair follicles into the resting stage.<sup dir="ltr"><a href="https://womensconcepts.com/haircare/hair-growth/laser-hair-growth-treatment#footnotes" dir="ltr">[1]</a></sup></p><h3>Reduces inflammation&nbsp;</h3><p dir="ltr">Another mechanism through which low-level laser treatment supports hair growth is due to its anti-inflammatory effects. It turns out laser energy can reduce the inflammation that weakens the hair follicle.<sup dir="ltr"><a href="https://womensconcepts.com/haircare/hair-growth/laser-hair-growth-treatment#footnotes" dir="ltr">[6]</a></sup> This is especially effective in <em dir="ltr">alopecia areata</em>, an inflammatory condition that causes a sudden and excessive loss of hair.</p><h2>How effective is it?</h2><p dir="ltr">Laser hair growth treatment can be very effective in the early stages of alopecia and in cases of thinning hair. Unfortunately, the effectiveness of the treatment decreases with the severity of the condition. The good news, though, is that LLLT can improve the three most common forms of hair loss: androgenic alopecia, alopecia areata, and chemotherapy-induced alopecia.<sup dir="ltr"><a href="https://womensconcepts.com/haircare/hair-growth/laser-hair-growth-treatment#footnotes" dir="ltr">[7]</a></sup> According to a study published by the&nbsp;<a href="https://www.springer.com/journal/40257" rel="noreferrer noopener" dir="ltr">American Journal of Clinical Dermatology</a>, low-level laser therapy could successfully treat pattern hair loss in both women and men.

The lasers emit low-level energy that doesn’t pose major risks to the user and causes no form of pain or discomfort. Plus, the treatment does not require medical attention or time for recovery.

<p>Laser treatments have been game-changers in the dermatological field for the past decades and appear to be one of the most demanded (and under-the-radar) solutions for stimulating hair growth. The cutting-edge treatment is technically called low-level laser therapy (LLLT), and its ability to encourage hair production in people suffering from various forms of alopecia has been heavily researched.
