Platelet-Rich Plasma (PRP) is a concentrated solution derived from a person’s own blood. This medical treatment has gained recognition in regenerative medicine for its potential to stimulate healing and tissue regeneration. For hair restoration, PRP involves processing a patient’s blood to isolate the plasma rich in platelets, which is then reintroduced into the scalp. This approach aims to support hair follicles and address concerns related to hair thinning.
PRP’s Role in Hair Regrowth
The effectiveness of PRP in promoting hair regrowth comes from its concentrated platelets. Platelets are small blood cells recognized for their role in clotting, but they also release numerous growth factors and cytokines. When these concentrated growth factors are injected into the scalp, they stimulate dormant hair follicles. This stimulation can prolong the anagen, or active growth, phase of the hair cycle.
These growth factors also promote new blood vessel formation, improving blood flow and nutrient delivery to the hair follicles. Enhanced circulation helps create a more supportive environment for hair growth and strengthens existing hair strands. The procedure is autologous, using the patient’s own blood.
Does PRP Cause Hair Loss?
PRP treatment itself does not typically cause permanent hair loss. While some individuals may observe increased hair shedding after the procedure, this is generally a temporary phenomenon. This shedding is often an indication that the treatment is initiating changes within the hair follicles. Reports of actual hair loss as a direct and negative result of PRP are uncommon.
Temporary Hair Shedding Post-PRP
Some individuals may experience a temporary increase in hair shedding following PRP treatment, a phenomenon sometimes referred to as “shock loss.” This shedding often represents a normal, transitional phase in the hair growth cycle. The concentrated growth factors in PRP stimulate dormant or miniaturized hair follicles, prompting them to enter a new growth phase.
As new, stronger hairs begin to grow, they can push out older, weaker hair strands that were already in a resting or shedding phase. This process, known as telogen effluvium, is temporary and signals the treatment is revitalizing hair follicles. Typically, this shedding can last from a few weeks, often between two to eight weeks, though full recovery and new growth might become noticeable within three to four months.
Other Potential Causes of Hair Loss
If hair loss persists or appears unexpectedly after PRP treatment, consider other potential causes unrelated to the procedure. Underlying hair loss conditions, such as androgenetic alopecia, can continue to progress despite treatment. Factors like chronic stress, significant dietary deficiencies, or hormonal imbalances can also trigger or worsen hair shedding.
Certain medical conditions or medications might also contribute to hair loss, independent of PRP therapy. While rare, improper technique during the injection process or inadequate sterile practices could lead to complications like infection, though these are not direct causes of hair loss.
Choosing a Safe PRP Provider
Selecting a qualified and experienced medical professional for PRP treatments minimizes potential risks and optimizes outcomes. It is advisable to research the provider’s credentials, ensuring they have appropriate training and experience in performing PRP for hair restoration. Inquiring about their clinic’s sterile practices and safety protocols is also a reasonable step.
Understanding what to expect during and after the procedure, including potential temporary shedding, helps manage expectations. If any unexpected or prolonged hair loss, severe discomfort, or signs of infection occur after treatment, consulting with the treating physician promptly is recommended.
