Polynucleotides for hair loss in London

Most people who ask about scalp polynucleotides are women whose parting has widened or whose ponytail has thinned over a few years. That gradual pattern is what the treatment is used for.

Female pattern hair loss

Hair thins across the top of the head while the hairline stays in place. It often runs in families. In a 2015 study of women with this pattern, the 20 who had 12 weekly scalp injections of a closely related DNA product gained about 18% in hair count and 14% in hair thickness.

Androgenetic alopecia in men and women

This is the medical name for pattern hair loss in both sexes. In a 2025 study, 28 people with it had four polynucleotide injections four weeks apart, and their hairs grew measurably thicker and denser from the first month. The study had no comparison group, so the size of the effect is uncertain.

Sudden hair shedding

Hair that comes out in handfuls over weeks can be a reaction to illness, stress, weight loss or low iron, and it usually grows back once the cause settles. Polynucleotides are not the first step for shedding; finding the cause is.

The NHS advises seeing a GP about the cause of hair loss before going to a commercial hair clinic. Illness, stress, weight loss and iron deficiency can all cause temporary loss, and a blood test can check for some of these. Patchy hair loss, or a scalp that is red, scaly or sore, needs a doctor's diagnosis before any cosmetic treatment. The GP can also discuss the licensed medicines, which are the main treatments for pattern hair loss. NHS advice on hair loss sets out the causes.

PRP uses platelet-rich plasma spun from your own blood and injected into the scalp. Polynucleotides are a ready-made purified gel, so no blood is taken. Both aim to support the follicles, and neither regrows hair on a bald area. No published study has compared the two head to head. In the 2015 study, women who had one PRP session plus the DNA injections gained more hair thickness than those who had the injections alone, though not more hairs, which is why some practitioners combine them.

After an assessment of your scalp and history, the practitioner injects small amounts of polynucleotide gel across the thinning area with a fine needle, sometimes after numbing cream. A session takes 30 to 45 minutes. The practices that publish scalp courses give three or four sessions about four weeks apart, then decide on maintenance by how your hair responds. Photographs taken at the start make the change easier to judge.

Hair grows slowly, so the scalp changes later than skin does. Less shedding may be the first sign. In the 2025 study, hairs were measurably thicker and denser from the first month and kept improving through the course, but a change you can see in the mirror takes longer, so the course is judged a few months after the last session. Expect existing hair to look fuller rather than new hair to appear where the scalp is bare. The published studies describe what groups of patients saw.
