Male hair loss usually starts long before it becomes obvious. The temples creep back, the crown thins in bright light, and the hair you have left feels finer than it used to. By the time it shows in photos, a meaningful amount of density is already gone. Injectual's hair rejuvenation treatment for men uses DR.CYJ Hair Filler, a peptide and hyaluronic acid injectable delivered directly into the scalp, polynucleotides and exosomes (calecim and purasomes). It is designed to strengthen the hair you still have and push dormant follicles back into an active growth phase. No surgery, no transplant, no daily foam. What Is Hair Rejuvenation for Men? Hair rejuvenation is a non-surgical injectable treatment for thinning hair. A tailored formula of hyaluronic acid, peptides and nutrients is injected into the scalp using very fine needles, placed strategically along the hairline, temples and thinning zones. The formula works on three fronts: improving blood supply to the follicle, signalling dormant follicles to re-enter their growth phase, and thickening the individual hair shaft. The result is more density from the follicles you already have, rather than transplanted hair moved from elsewhere. Why Men Choose Injectable Hair Rejuvenation Most men who come to our London clinic are in the same position. Not bald, but noticeably thinner than five years ago, and not ready to commit to a transplant. No downtime. Straight back to work. No shaved donor area, no scabbing, no visible signs. No blood draw. Unlike PRP, nothing is taken from you. The formula is ready to inject. Works on the whole scalp. A transplant moves hair into specific bald patches. Hair filler treats the entire area, including hair that is still there but weakening. Preserves what you have. Slowing and strengthening existing hair matters as much as regrowth. Most men underestimate this. Discreet. A short appointment, nothing to explain to anyone. A realistic first step. If you later decide on a transplant, a healthier scalp and stronger surrounding hair only improves the outcome. Who It Works Best For Hair rejuvenation is not a solution for every stage of male hair loss. Being honest about that saves you money and disappointment. You are likely a good candidate if you have: Gradual thinning noticed over six months or more Early to moderate recession at the temples or hairline Diffuse thinning across the crown where hair is finer rather than absent Increased shedding after stress, illness or a period of poor sleep and nutrition Hair that still grows in the area, just thinner and weaker than before The willingness to complete a course rather than expecting one session to fix it You are less likely to see meaningful results if the area is completely bald with no follicular activity, or if your hair loss is driven by an untreated medical condition. In those cases we will tell you directly and point you toward the right route, whether that is a surgical opinion or a medical workup first. How the Treatment Works Your practitioner examines your scalp first, maps the areas of loss, and sets a dosing plan. The formula is then injected into the scalp using a very fine needle at multiple points across the treatment area. The session is short. For men, we typically recommend a course of three sessions spaced two to four weeks apart, then a maintenance course roughly twice a year to hold the gains.

It is also the practical choice for men who dislike the idea of a blood draw or cannot commit to applying a topical every single day.
