Alma TED Explained: How Soundwave Technology Delivers Treatment to Your Scalp

Clinical content by Jeffrey Vogel, MD, MPH – Chief Medical Officer, Boundless

Most hair restoration treatments involve something going into the scalp – either injections or microneedling. Alma TED does something different. It delivers treatment through the surface of the scalp without breaking it at all.

That distinction matters practically, and it is worth understanding how the technology actually works.

What Alma TED is and how it works

TED stands for TransEpidermal Delivery. The device uses a combination of ultrasound energy and air pressure to temporarily increase scalp permeability – opening pathways that allow topically applied solutions to penetrate into follicular tissue without needles.

The ultrasound creates acoustic waves that temporarily loosen the junctions between skin cells. Air pressure then drives the solution through those pathways, past the surface layer and into the deeper dermis where follicles live. The result is delivery that reaches follicular depth through the surface rather than through it.

What gets delivered

At Boundless, Alma TED is used in two primary hair restoration contexts.

In PRP & Alma TED – our core hair protocol – the device delivers your platelet-rich plasma across the entire scalp, plus the Alma TED Hair Care Formula: a proprietary serum containing growth factors, peptides, and DHT-targeting actives. [See this post for why combining PRP with Alma TED changes the equation.]

In Secretomes + Alma TED, the same delivery technology carries a personalized secretome preparation – the most comprehensive biological signal available – without any injections. [See this post to learn more about secretomes.]

What the experience actually feels like

Dr. Vogel notes that patient comfort with Alma TED is consistently one of the things men are most surprised by. The sensation is a warm, vibrating pressure – similar to a scalp massage. No numbing is required, no marks are left on the scalp, and the only needle in a PRP + Alma TED session is the small blood draw at the start.

Sessions run 30 to 45 minutes. Most men return to their normal day immediately afterward.

Final Thoughts

Alma TED is a delivery mechanism with a real biological rationale. For men who have avoided hair restoration due to the needle component, or who want broad, even scalp coverage, it changes what's practically accessible.
