The rich concentration of platelets now has to be applied to the scalp where hair loss has begun. Therefore, preparing the scalp to receive the PRP is necessary. For this, the scalp is stimulated to activate the wound healing process. Topical anesthesia is applied on the portion of the scalp where PRP will be injected. To prepare the scalp for PRP application, a special micro needling roller device is used. This roller device causes microtrauma to the lower layer of the scalp that induces other healing and growth repair cells into action. The microneedle roller uses 192 unique needles made up of titanium that pierce into the skin and open the skin to create micro wounds. Since it uses less pressure, the pain is minimal. Immediately, the highly concentrated PRP is injected in many different areas of the scalp.
