What is PRP?
PRP is the term used for Platelet-rich plasma. It is prepared by the centrifugation of the patients own blood. For its preparation two spins are required in the centrifuge machine, the first spin is known as the soft spin in which plasma is separated, this plasma is again centrifuged ( hard spin)to prepare platelet-rich plasma. Normally we take 23 ml of blood mix it with 2 cc of ACD solution to prepare around 3 ml of PRP. After the second spin of the centrifugation process, platelets get settled down at the bottom of the tube. The upper part is platelet poor plasma. (PPP). 3 ml of PRP is prepared by mixing platelets plaque with the plasma after discarding upper platelet poor plasma.
PRP is injected into the scalp by multiple injections. The dose is 0.1 ml per square cm of the scalp intradermally. 30 gauge needle is used along with the simultaneous use of the vibrator, this reduces pain to the great extent.
As PRP is prepared by the patients own blood so there is no side effect of the procedure. Also, no special precaution is needed after PRP treatment result.
Platelet-rich plasma is the rich source for the growth factors released by the platelets. These growth factors are released when platelets come in contact with the collagen present in the tissue. They are known for their healing properties and used nowadays in the various field of medicine like dentistry, orthopedics, and gynecology.
Role of PRP in Hair growth – Stem cells present in the hair roots get stimulated by the growth factors released by the activated platelets.
Normally 4-6 sittings of PRP at the interval of 4-6 weeks is given to the patients of hair loss. Results start coming after 2-3 sessions. After a complete course 6 sittings, maintenance sessions of PRP can be given twice a week.
PRP is mainly effective for the miniaturized hair roots. If hair roots are dead than it isn’t possible to get growth from them. Diffuse pattern hair loss in men and female pattern hair loss are very much benefited from the PRP. It is also given along with the hair transplant procedure to promote the growth of the existing follicles. It also accelerates the healing process and reduces scar formation.
Different studies are there in the support of the effect of PRP on hair growth. We got Best Results of PRP in hair loss when we combine medical treatment in the form of multivitamins and other nutrients (rejuvenate hair regime) along with the PRP.
In patients of alopecia areata, PRP is given along with the steroid. Studies are there to support the role of PRP in alopecia areata but more research is required.
