FOUNDER'S TIMELINE
When I personally started noticing changes. Full write-up below.

S 01

The entire kitchen sink, itemized.

Hover any element to read the mechanism of action & dose rationale.
Editor's note
We included an ingredient only if it cleared three bars:

(a) at least one randomized, controlled human trial published in a peer-reviewed journal,

(b) a plausible, published mechanism of action,

(c) a safety profile suitable for daily topical use.

That's a deliberately short list.

Most "natural" hair products are a handful of marketing-friendly plant extracts dropped into aloe gel. Kitchen Sink Sender is the opposite: a deliberately narrow set of six ingredients. Each one has been studied for a different aspect of scalp and follicle health — inflammation, circulation, androgen activity, extracellular matrix support. Rather than one ingredient doing one thing, we wanted the full picture in one bottle.

S 02

The science behind every ingredient.

Every active maps onto a specific node in the miniaturization pathway.

The miniaturization cascade.

Androgenic alopecia isn't "hair falling out" it's hair shrinking. Over successive growth cycles, genetically susceptible follicles on the scalp's vertex and hairline progressively miniaturize in response to 5a-dihydrotestosterone (DHT), ambient scalp inflammation, compromised microvasculature, and ECM degradation around the dermal papilla.

Minoxidil addresses one of these mechanisms. The six ingredients in Kitchen Sink Sender were chosen because the published research covers all of them — DHT activity, vasodilation, ECM integrity, follicular energy metabolism. That's the thesis: instead of one pathway, cover the full map.

vs. the prescription stuff.

Honest answer.

Why not just take finasteride?

Maybe you should. Finasteride works. Minoxidil works. We're not here to talk you out of either.

Finasteride does one thing systemically. We do six things topically.

If you can't tolerate the sides, if you want to try botanicals before escalating, or if you're already on Rx and want a well-formulated topical to stack — that's who we made this for.

If you're Norwood IV+ and losing ground fast, see a dermatologist. We'll be here if you want to add us to the stack.

8x
The secret weapon

Microneedling 1-2x per week creates microchannels that dramatically increase topical absorption. A peer-reviewed study (Dhurat et al., 2013) reported up to 8x improvement in hair count when combining topicals with derma rolling. That's why every Protocol subscription includes a free 0.5mm derma roller.

The protocol. Overnight, then eggs.

Apply at night. Let it work while you sleep. Rinse with eggs in the morning.
01PM
STEP APPLY
0.5 mL before bed.

Half a dropper to a dry scalp. Part the hair in four sections. Apply directly to the scalp, not the hair. Let it work overnight while you sleep.

~ 45 sec
02PM
STEP MASSAGE
Finger-press for 60 seconds.

Don't scrub, press. Mechanical scalp stimulation increases dermal papilla perfusion and aids penetration. Then sleep on a dark pillowcase.

~ 60 sec
03AM
STEP RINSE
Morning egg wash.

Yes, eggs. Crack 1-2 eggs, whisk, massage into wet hair in the shower. The protein, biotin, and lecithin strengthen the shaft while rinsing out the overnight treatment. Rinse with cool water.

~ 3 min
+8x
SECRET WEAPON
Microneedle 1-2x weekly.

Use the included 0.5mm derma roller before your evening application. Creates microchannels for dramatically better absorption. This is what takes the protocol from good to exceptional.

~ 3 min

Why eggs? Raw eggs contain biotin, protein, and lecithin that coat and strengthen the hair shaft. They also emulsify the oil-based serum for easy rinsing. Use cool water to avoid cooking the egg in your hair. This is an old-school bodybuilder trick that actually works.

Why microneedling works: The 0.5mm needles create temporary microchannels in the epidermis, increasing topical absorption by up to 8x. It also triggers a wound-healing response that upregulates growth factors at the follicle. Wait 24 hours between rolling sessions.

KSS - Founder
KSS, Founder 2026

I started losing my hair at 23. My doctor offered finasteride. My dermatologist offered minoxidil. Both worked. Both had tradeoffs I wasn't willing to live with indefinitely.

So I opened PubMed. Fourteen months and one spreadsheet later, I had six non-pharmaceutical actives each with a real trial, each hitting a different node in the miniaturization pathway. I'm 26 now and my hair is the healthiest it's ever been. That spreadsheet is the product.

Questions we actually get.

Written by the founder; not by a content team.
Q.01How does this compare to minoxidil?+
Rosemary oil — the base of our formula — showed statistical non-inferiority to 2% minoxidil in a 6-month head-to-head trial [Ref. 1]. We added five more studied ingredients on top of that. For people who want to try a botanical-first approach, that's the research foundation. For Norwood III+ we'd suggest combining KSS with a proven Rx regimen rather than replacing it outright.
Q.02How fast will I see results?+
You'll start seeing the beginnings of results around month 3 reduced shedding, early vellus hairs. We highly recommend continuing until at least month 6 to see the full response. The follicle cycle is slow; don't judge the protocol before you've given it a fair shot.
Q.03Is there a shedding phase?+
Mild, usually in weeks 2-4, and much less pronounced than minoxidil. It's a sign follicles are synchronizing into a new growth cycle. Push through it.
Q.04Can I use it with finasteride?+
Yes. There's no contraindication. Finasteride is an oral 5a-reductase inhibitor. KSS is a topical serum with a different mechanism set. Many users combine both.
Q.05Why is it so expensive?+
GHK-Cu peptide is expensive in the concentrations required for efficacy. Rosemary essential oil at 10% (the trial dose, not a marketing dose) is expensive. A pro-penetrating carrier that doesn't use propylene glycol is expensive. We chose fidelity to the literature over a cheaper bill of goods.
