Alopecia, or hair loss, is a common condition that affects millions of people around the world. Both men and women can experience hair loss, leading to reduced self-confidence and emotional distress. While several treatments exist to address this concern, micro-needling and platelet rich plasma have gained attention as innovative approaches to combating hair loss. In this article, Dr. Shikha Aggarwal, the Best Hair Fall Doctor in Ludhiana, explains the concept of micro-needling and platelet rich plasma and their potential benefits in promoting hair regrowth.
What is the relationship between platelets and hair growth?
Platelets are one of the four major components of blood (the others being red blood cells, white blood cells, and plasma). Platelets help cells develop and regenerate. As the term "platelet-rich plasma" implies, platelets are approximately five times more concentrated in PRP than in regular blood. This platelet concentration is beneficial because platelets generate growth factors that are known to aid in wound healing and tissue rebuilding.
When it comes to hair loss, the hypothesis is that platelets injected deep into the scalp to reach the hair follicle's bottom may activate a specialized population of cells known as dermal papilla cells, which play an important part in hair development.
Getting platelet-rich plasma and injecting it
A blood draw and a centrifuge are required to obtain PRP. PRP is created by extracting blood from the arm and spinning it down in a centrifuge (a machine that spins at high speeds to separate blood components). After centrifugation, the plasma rises to the top, while the PRP is at the bottom. A second spin is sometimes done to boost the platelet content of the plasma.
The PRP is extracted and injected into various locations of hair loss on the scalp. To maintain the benefits, the typical treatment schedule consists of three one-month-apart sessions followed by maintenance sessions every three to six months.
Some kinds of hair loss have more evidence for platelet-rich plasma than others.
The majority of PRP research for hair loss has focused on its use to treat androgenetic alopecia (AGA). This disorder, often known as hormone-related baldness, can affect both men and women. Hair loss in males with AGA is most common on the top and front of the head. Thinning happens on the top and crown of the head in women and frequently begins with the center hair \part becoming broader. Evidence shows that PRP may be most effective when paired with other AGA therapies, such as topical minoxidil (Rogaine) or oral finasteride (Propecia), an anti-androgenic medicine.
There is insufficient data to draw conclusions on the efficacy of PRP for other kinds of hair loss, such as telogen effluvium (stress-related hair loss), alopecia areata (autoimmune-related non-scarring hair loss), or scarring hair loss.
Understanding Micro-Needling:
Micro-needling, also known as collagen induction therapy, is a minimally invasive cosmetic procedure that involves creating tiny punctures in the skin using a specialized device called a derma roller or a derma pen. Traditionally, micro-needling has been used to treat various skin concerns, such as scars, wrinkles, and hyperpigmentation. However, recent studies have suggested its potential effectiveness in stimulating hair growth as well.
The Science Behind Micro-Needling and Hair Regrowth
Micro-needling promotes hair regrowth through two primary mechanisms:
Stimulation of Hair Follicles: The micro-injuries caused by the tiny needles during the procedure activate the body's natural healing response. This process releases growth factors and stimulates blood circulation in the scalp, providing essential nutrients and oxygen to the hair follicles. Consequently, dormant or weakened hair follicles may be rejuvenated, leading to hair regrowth.
Enhanced Absorption of Topical Treatments: Micro-needling creates microscopic channels in the scalp, increasing the absorption of topical treatments such as minoxidil or platelet-rich plasma (PRP). These treatments, when combined with micro-needling, can penetrate deeper into the scalp and reach the hair follicles more effectively, potentially promoting hair growth.
Procedure and Safety Considerations
Micro-needling for hair loss is typically performed by a qualified dermatologist or a trained aesthetic professional. The procedure involves the following steps:
Cleaning and numbing the scalp to minimize discomfort.
Applying a suitable topical treatment, such as minoxidil or PRP, to the scalp.
Gently roll the derma roller or use a derma pen to create microscopic punctures in the scalp.
Applying additional topical treatments to enhance absorption.
Providing post-treatment care instructions, including skincare routines and avoiding exposure to sunlight.
Micro-needling is generally safe when performed by professionals, but mild side effects like redness, swelling, or temporary discomfort may occur. Adhering to the post-treatment instructions and seeking professional advice is crucial to ensuring optimal results and minimizing risks.
