NOUVADerm for hair: what it is, and what it is not

Hair restoration systems of this kind work on follicles that are still alive but underperforming. The aim is to improve the environment the follicle is working in and to push miniaturising hairs back toward producing thicker, longer strands for longer.

That sentence contains the whole limitation. A follicle that is still there can be encouraged. A follicle that has closed cannot be reopened by any energy-based or topical treatment. This is why the examination comes before the device, and why we will sometimes tell a patient that a hair transplant consultation is the more honest referral.

It also explains why these systems are usually combined rather than used alone. Where pattern hair loss is the driver, the evidence base sits with established medical treatment, and a device is layered on top of that rather than in place of it. Anyone offering a device as a replacement for treating the underlying process is offering you the easier conversation, not the better plan.

We would not recommend this where an untreated medical cause is driving the loss. Treating a thyroid disorder or an iron deficiency first is both cheaper and more effective, and skipping that step wastes a course of treatment.

We would not recommend it during an active telogen shed. That process usually resolves once the trigger has passed, and treating through it makes it impossible to tell what caused any improvement.

We would not recommend it where the follicular openings have been lost across the area of concern. There is nothing there to stimulate, and a series of appointments will not change that. Surgical restoration is the honest conversation in that case.

And we would not recommend it to anyone who cannot commit to the full course and the home care. A partial course produces a partial result and an accurate sense that it did not work.

Plan for the series, not the session. Pricing a single appointment tells you almost nothing, because a single appointment is not the treatment. We quote the course at consultation once we have seen the scalp, and we will tell you what maintenance looks like afterwards.

Results from any hair treatment are held, not banked. Pattern hair loss is a progressive process, and the treatment is working against it continuously. Stopping does not undo the gain overnight, but it does return the follicle to its previous trajectory.

If you want one number to judge value by, use cost per month of the whole plan including maintenance, rather than the price on any one appointment. It is the only figure that reflects what you are actually buying.
