Low level Laser Therapy LLLT involves exposing the tissue to low levels of red and

near-infrared light and is known as “low level” because of its use of light at energy
densities that are much lower compared to conventional laser therapy that
is used for ablation, cutting, and thermally coagulating tissue. LLLT also
known as *“cold laser”* because the power density is much lower than those
with conventional lasers.

Hair loss and hair thinning are common hair-related complaints today. Hairfall has multiple causes including nutritional, hormonal or metabolic and treatment of hair loss includes tackling these issues along with treatments aimed to salvage maximum follicles. Conventional treatment involves finding the exact cause of the trigger for hair loss. In conditions like female pattern and male pattern baldness, conventional treatments include Minoxidil and Finasteride. Often they help in controlling hair fall and preventing receding hairline but patients seeking hair regrowth are looking for options like platelet rich plasma or fibrin. 

In this article we talk about the two most important solutions for hair regrowth – Platelet rich plasma (PRP) and Platelet rich fibrin (PRF) with the help of 5 commonly asked questions about them.

Q1) What Is PRP? How Does It Help In Hair Growth?
PRP is defined as ‘a biological product which is a portion of the plasma fraction of autologous blood with a platelet concentration above the baseline (before centrifugation)’. As such, PRP contains not only a high level of platelets but also the full complement of clotting factors, the latter typically remaining at their normal, physiologic levels. It is enriched by a range of GFs, chemokines, cytokines, and other plasma proteins. Platelets have more than 300 growth factors, the most important are EGF, PDGF. VEGF and IGF etc. The growth factors in PRP promote fibroblast function, stimulate new blood vessel formation and promote wound healing.

We all know that hair growth is dependent on the stem cells in the bulge area of the hair follicle. PRP containing growth factors helps in activation and proliferation of these stem cells preventing hair loss and improving hair fall. PRP also stimulates the blood flow and hence improves the diameter of  the hair follicle. The growth factors also improve the quality of the hair fiber, reducing dry and frizzy hair.
