Can PRP Regrow Hair -

Platelets are blood components together with white and red blood cells. The platelets are also called the “first responders”, given the fact that their primary working in the body is to respond to any sustained cut or wound by stopping excessive bleeding and fasten the healing process.

In line with the natural operations of platelets, scientists and researchers theorized the answer to can PRP regrow hair that by injecting concentrated platelets from patients’ blood into a specific area, they could fasten the process of healing.

Now, the process of obtaining PRP comprise of various steps including taking a blood sample from patients’ bodies and passing it through the centrifuge, which rotates the sample at high speed to segregate different blood components. Once it’s done, the medical professional can squeeze platelets from the blood for PRP injections.

Now, coming to our question regarding, “can PRP regrow hair”, it’s interesting to note that platelet-rich plasma is indeed potent to accelerate the tissue repair process in our bodies. This means that at least in theory the answer to can PRP regrow hair is positive and that the PRP injections can help regrow hairs by reversing the process of hair loss due to male pattern baldness or androgenetic alopecia.

Step 1

The PRP process begins by extracting a blood sample from patients’ bodies. The blood will typically be extracted from the arm region.

Step 2

Once the sufficient blood sample is drawn from the body, the sample is then put into the centrifuge machine where it is rotated at high-speed. Typically, the sample will be rotated for about 10 minutes in the centrifuge machine. The resultant sample will have blood separated into three different layers including; platelet-poor plasma, platelet-rich plasma, and red blood cells.

Step 3

Once PRP is successfully separated from the other two components, the surgeon/doctor will draw PRP into a medical syringe to be injected into the desired body areas (Scalp in case of hair loss treatment).

The treatment was especially found effective to treat androgenetic alopecia. However, the small sample sizes of the study may be one concern for the researchers as it limits the factors of their investigation.

In another study conducted in 2019 and featured in Dermatologic Surgery, 19 researched were studied covering a sample size of 460 people to study the effectiveness and potency of PRP injections to hair loss.
