Alma TED vs Traditional PRP Delivery: What the Difference Means for Your Scalp
Clinical content by Jeffrey Vogel, MD, MPH – Chief Medical Officer, Boundless
If you are researching PRP for hair loss, you will find it delivered two primary ways: via scalp injections or via Alma TED, a needle-free ultrasound delivery system. Both use the same PRP prepared from your blood. The differences are in how it gets there.
How traditional PRP injection works
After your blood is processed and the platelet-rich plasma is separated, it is delivered through a series of small injections across the treatment area. The scalp is numbed beforehand. The advantage is precision – PRP goes exactly where the needle goes, at a specific depth. For focal thinning in discrete zones, this targeted delivery can be meaningful.
The limitation is coverage. Injections address specific points rather than distributing the biologic uniformly across the full scalp. For men with diffuse thinning, complete even coverage is harder to achieve.
How Alma TED delivery works
Alma TED uses ultrasound energy and air pressure to drive PRP through the scalp surface without needles. The acoustic waves temporarily increase permeability across the entire treatment area, allowing the biologic to penetrate to follicular depth uniformly.
Alongside the PRP, the Alma TED Hair Care Formula – containing growth factors, peptides, and DHT-targeting actives – is delivered in the same session. This adds an external regenerative signal that injection delivery alone does not include. [See this post for the full Alma TED mechanism breakdown.]
Which produces better results?
At Boundless, we believe the answer depends on the presentation. For diffuse thinning across the scalp – the most common pattern in male androgenetic alopecia – Alma TED's even distribution has advantages. For men with focal thinning in discrete areas, targeted injection delivery offers more spatial control.
The evidence base for PRP in hair restoration is well-established across delivery methods. Systematic reviews confirm meaningful improvements in hair count and density (Gupta et al., JEADV, 2018). The delivery method determines the distribution pattern more than the biological mechanism.
At Boundless, most men start with PRP & Alma TED. Traditional injection delivery is available selectively when focal precision is the clinical priority.
Final Thoughts
Both methods use the same biology. The differences are in coverage, comfort, and what additional elements accompany the delivery. [See this post on the full PRP candidacy assessment.]
