PDRN Scalp Treatment: Regenerative Hair Therapy Guide

PDRN scalp treatment is performed as a series of intradermal injections across the affected areas of the scalp. The procedure begins with a scalp assessment to identify areas of thinning and determine the treatment zone. The scalp is cleansed with antiseptic solution. Unlike facial treatments, topical numbing is not always used for scalp injections, as the scalp has relatively high pain tolerance. However, some practitioners offer topical anesthetic or nerve blocks for sensitive patients.

The PDRN solution is loaded into syringes with 30-32 gauge needles or an automated mesogun device. Using a nappage or point-by-point technique, the practitioner administers superficial intradermal injections (depth 1-2mm) spaced approximately 1cm apart across the entire area of concern. The injection pattern follows the distribution of thinning — typically concentrating on the frontal hairline, crown, and mid-scalp in androgenetic alopecia, or across broader areas in diffuse thinning.

Each injection deposits approximately 0.02-0.05ml of PDRN solution. A full scalp session typically requires 50-150 injection points depending on the treatment area size. Some practitioners combine PDRN with other regenerative agents such as biotin, growth factors, or PRP in a cocktail approach, though PDRN is effective as a standalone treatment.

The procedure takes approximately 30-45 minutes. Patients may experience mild scalp tenderness and pinpoint bleeding at injection sites, which resolve within hours. Hair washing can be resumed after 24 hours using a gentle shampoo. The standard protocol involves sessions every 2-4 weeks for 6-10 treatments, followed by maintenance sessions every 1-3 months.
