The Science
Hair loss has a science. Here is our working.
We start where a dermatologist starts - your stage, your follicle, your timeline - and let the science set the limits of what we claim. What follows is the reasoning, in the order a doctor would walk it.
CH. 01
Start from the stage, not the shelf.
Dermatologists grade hair loss on a seven-stage scale. Everything else follows from it - which mechanism is failing, what can still respond to actives, and when a clinic is the answer. A product that works at stage 2 wastes your money at stage 5, so the first thing TGC does is place you.

7STAGE I–II
The routine window
Follicles are miniaturising but alive. Named topicals and nutrition can settle the fall and hold what you have - this is the one window where the products earn their place. There is no minoxidil or finasteride in them, so holding on to the hair you have is what they do.
STAGE III+
Doctor in the loop
Beyond stage II we send you to a free in-clinic consult instead of a cart. A doctor should be reading your pattern before anything else happens.
STAGE IV–V
The bigger conversation
With significant visible scalp, a transplant is likely the real fix - and that is what we will point you to. There is nothing worth selling you where the follicles have already gone.
CH. 02
The cycle sets the clock.
Anagen - growth 2–7 YEARS · ~85–90% OF FOLLICLES
The follicle actively builds hair. Almost everything on your head is in this phase right now - it’s the phase every TGC active is chosen to protect and prolong.
Catagen - transition ~2–3 WEEKS
The follicle detaches and shrinks. Brief, invisible, unavoidable.
Telogen - rest & shed ~3 MONTHS
The old hair rests, sheds, and the follicle restarts. Excess shedding means too many follicles pushed here at once - the first thing the analyzer screens for.
A follicle that re-enters growth in month one only shows visible length by month three. That is the whole reason we speak in 3–6 month timelines: the biology does not move faster than that, whatever anyone tells you.
It is also why Trichocycle’s nutrition runs in sequenced phases across the month instead of one flat daily dose.
CH. 03
Named actives or nothing.
If an ingredient can’t be named, dosed and defended with published work, it doesn’t go in the bottle. Here is the register, entry by entry - what each active is, what it does, and what the research behind it actually says.
A-01IN: SERUM · SHAMPOO
Procapil®
Biomimetic peptide
Anchors hair at the follicle and slows miniaturisation by improving blood flow and countering DHT at the root.
Clinical detail
A complex of biotinyl tripeptide-1, oleanolic acid and apigenin. Cosmetic-science research links it to a shift of follicles from the shedding (telogen) phase back toward growth (anagen) - which is about keeping the hair you have on your head, not adding to it.
A-02IN: SERUM
Capilia Longa®
Botanical stem-cell
A turmeric-stem-cell derived active that helps hold follicles in their growth phase for longer, so fewer of them shed early.
Clinical detail
Derived from Curcuma longa stem cells. Published in-vivo work reports reduced hair loss over time, building gradually - consistent with the cycle in Fig. 02. What it is for is hair you keep.
A-03IN: SERUM
Encapsulated Caffeine
Circulation
Boosts scalp microcirculation and energises the follicle; encapsulation helps it reach the scalp intact.
Clinical detail
Caffeine is a well-studied scalp active supporting microcirculation around the follicle - a supporting role alongside Procapil and Capilia Longa.
A-04IN: SERUM
Copper Tripeptide‑1
Signalling peptide
A small signalling peptide with regenerative, anti-inflammatory activity that supports a healthier follicle environment.
Clinical detail
GHK-Cu is one of the most-studied peptides in dermatology. On the scalp it supports follicular repair and a calmer environment - a supporting active, not a standalone treatment.
CH. 04
Where the evidence comes from.
STEP 1
Analyse the problem
Outcome data from 20,000+ Assure Clinic procedures shows which mechanisms go under-targeted, and at which stage.
STEP 2
Select the actives
Each active passes a three-part screen: clinical efficacy (min. two studies), a clean scalp-safety profile, ethical sourcing.
STEP 3
Test in the lab
Formulations are stress-tested across hair types under our in-house trichologists.
STEP 4
Validate in patients
An 8-week observational study at Assure tracks trichoscopy metrics before launch. Ship only past threshold.
The studies we build on
Peptide actives & the hair cycle
Biomimetic peptide complexes are studied for shifting follicles from shedding back toward growth - the basis of the serum’s follicle-strengthening role.
Curcuma longa stem cells & hair loss
Turmeric-root stem-cell actives are associated with reduced hair loss over a period of months.
Nutritional factors and hair loss
Iron, zinc and biotin deficiencies are independently associated with telogen effluvium - why nutrition sits inside the routine.
DHT and follicle miniaturisation
DHT-mediated miniaturisation is established as a driver of androgenetic alopecia - the mechanism the topicals are chosen to support against.
The clinic behind it
“The best product is the one that treats your actual problem. Everything else is marketing.”
Dr. Abhishek Pilani · Gold Medalist Dermatologist · Co-Founder, Assure Clinic
TGC is the product arm of Assure Clinic - built on what 20,000+ procedures taught its dermatologists about which mechanisms matter, and at which stage they still matter.
