Let’s talk amino acids. Not the gym-bro kind. Not the “take this powder and become a superhero” kind. We mean the quiet, unglamorous building blocks that your hair follicles depend on every single day - whether you realise it or not.

If vitamins are the cheerleaders, amino acids are the construction crew. No drama. Just results. And Matt Miller didn’t include amino acids in his FollicleFood formula on a whim. They’re some of the most important, most practical ingredients for encouraging real hair regrowth.

Here’s why.

Hair is protein. Protein is built from amino acids. End of story.

It’s surprising how many hair products forget this basic fact.

Your hair is made of keratin - a strong, fibrous protein. And keratin itself is made from amino acids. If the follicle doesn’t have enough of these building blocks, it can’t produce thick, sturdy strands. Instead, it turns out hair that’s weak, thin, and breaks at the slightest inconvenience.

Amino acids are the raw materials. No materials, no hair.
It really is that simple.

Why topical amino acids matter more than oral supplements

Sure, you can swallow amino acids. Nothing wrong with that. But the body tends to use them for far more important things than your hair - like repairing muscles and keeping your organs functioning.

Your scalp is basically the last in line. When you apply amino acids topically, you skip the queue. You’re delivering the goods directly to the follicle, and the follicle goes:

“Oh thank goodness, we can actually build something decent now.”

This is why FollicleFood includes amino acids right in the serum - because your scalp shouldn’t have to fight with the rest of your body for resources.

The three stars of the show: Valine, Leucine & Isoleucine

FollicleFood uses a trio of branched-chain amino acids (BCAAs):

• Valine

• Leucine

• Isoleucine

These aren’t random additions - they’re chosen for very specific reasons.

🔸 They support keratin production

Keratin relies heavily on these amino acids. More available building blocks = stronger hair fibres.

🔸 They help follicles recover

Hair follicles cycle through growth, rest, and shedding. Stress, hormones, and nutritional deficits can knock this cycle off balance.
BCAAs help support cellular repair, giving follicles the boost they need to stay in the active growth phase for longer.

🔸 They thicken each individual strand

Even before regrowth begins, amino acids strengthen the diameter of existing hairs. Thicker strands instantly make hair look fuller.

🔸 They help reduce breakage

Amino-acid-supported keratin is tougher, smoother, and far less prone to snapping — which means more length retention and less thinning.

Amino acids & the scalp: an underrated duo

A healthy scalp needs hydration and structure just as much as the follicles do.
Topical amino acids help support:

• moisture balance

• scalp barrier strength

• reduced irritation

• better nutrient absorption overall

In other words: they set the stage so every other ingredient in the serum can do its job even better.

The magic is in their simplicity

Amino acids don’t rely on hype.
They don’t need to be “activated by moonlight” or extracted from some rare flower on the side of an impossible mountain.

They’re basic.
They’re essential.
They’re effective.

And when you deliver them directly to the follicles, they quietly transform the way your hair grows - strand by strand.

Matt Miller, who formulated FollicleFood, understood this and built the formula around real-world biology instead of wishful thinking.

The takeaway

If you want strong, resilient, properly formed hair, your follicles need amino acids — not occasionally, not theoretically, but consistently.

Topical amino acids are like handing your scalp a box of quality materials every morning and saying, “Here, build something good.”

And for many people, that simple act is exactly what kick-starts visible regrowth.
