Thinning hair in women: what changes, and what the research actually shows
Need guide · Hair at Health Royals · 7 min read
Hair rarely changes overnight. It changes quietly: a thinner ponytail, a wider parting, strands that break before they grow long. Understanding what is happening is the first step.
The short answer
• Hair is built mainly from keratin, a protein. Building it requires amino acids, and the enzymes that assemble them require specific micronutrients.
• Biotin and zinc contribute to the maintenance of normal hair. Zinc also contributes to normal protein synthesis, and vitamin B6 contributes to normal cysteine synthesis. Cysteine is a key amino acid in keratin.
• Hair Beautification™ provides Keranat®, a standardised millet seed extract, at 300 mg per daily capsule, together with zinc, vitamin B6 and biotin.
When hair starts to feel thinner
Most people do not notice hair changing by counting strands. They notice it in ordinary moments: the ponytail that needs an extra turn of the elastic, the parting that catches more light than it used to, the length that never quite arrives because the ends give way first.
These are three different things, and they are worth separating.
Density is how many hairs are growing in a given area. Diameter is how thick each individual strand is. Durability is whether a strand survives long enough to reach the length you want. A head of hair can change in any one of them without changing in the others.
Separating them matters, because they do not have the same causes and they do not respond to the same things.
Hair that feels thinner is not always hair that is falling out. Often it is hair that is growing finer, or breaking sooner.
What actually changes over time
Every hair follicle works in a cycle. A long growth phase, a short transition, a resting phase, and then release. At any moment, the hairs on your head are at different points in that cycle, which is why shedding some hair every day is normal rather than alarming.
What shifts with age, and around hormonal transitions in particular, is the balance of that cycle. Growth phases can shorten. New strands can emerge finer than the ones they replace. The scalp environment around the follicle changes too.
None of this is a malfunction. It is the same kind of recalibration that happens in skin, in bone and in metabolism, and it follows the same logic.
If you want the biology in more depth, we have written about it separately in the science behind fuller, stronger and shinier hair, and about the wider midlife transition in the hidden rhythm of menopause and midlife vitality.
The follicle is one of the most metabolically active structures in the body. It is sensitive to how well it is supplied.
Hair is protein, and protein has requirements
The visible hair shaft is largely keratin: a family of structural proteins built from amino acids and cross-linked into something strong enough to bend thousands of times without snapping.
One amino acid matters more than most here. Cysteine carries a sulphur atom, and it is those sulphur bridges between cysteine units that give keratin much of its strength.
Building that structure is not passive. It depends on enzymes, and those enzymes depend on specific micronutrients being available. This is where the nutritional side of hair actually sits: not in feeding the hair directly, but in supplying the machinery that assembles it.
You cannot nourish a hair that has already grown. You can only supply the follicle that is growing the next one.
Zinc, vitamin B6 and biotin: the documented roles
Three of the nutrients in Hair Beautification™ carry health claims authorised in the EU. We state them exactly as they are authorised, without extending them.
Zinc — 10 mg
Contributes to the maintenance of normal hair, and to normal protein synthesis.
Vitamin B6 — 1.4 mg
Contributes to normal cysteine synthesis, the amino acid at the heart of keratin.
Biotin — 50 µg
Contributes to the maintenance of normal hair.

These are not dramatic claims. They are precise ones, and precision is the point.
Keranat®: what the research on millet seed examined
Keranat® is a standardised extract from the seed of golden millet, developed in France. Its characterised compound is miliacin, a molecule found in the seed.
Millet has a long history as a traditional food, but the reason it appears in a formulation like this is narrower: a defined extract, at a defined daily amount, that has been examined in human research.
We describe what that research measured rather than what it promises. The published work on Keranat® examined hair-related measures over a defined period in women, using the extract at a specified daily amount.
Hair Beautification™ provides 300 mg of Keranat® per daily capsule.
Two things are worth stating plainly. Ingredient research is research on the ingredient, not on our finished product. And a supplement is one input among many, alongside sleep, stress, nutrition, hormones and genetics.
Our full write-up on the ingredient is here: golden millet and the biology behind healthy-looking hair.
Naming the extract, the compound and the amount is what makes a claim checkable. That is why we do it.
Hair Beautification™
One capsule a day. Ninety capsules. Designed to be taken for at least twelve weeks, because that is the timescale on which hair changes are visible at all.
Per daily capsule
Keranat® standardised millet seed extract — 300 mg
Zinc — 10 mg
Vitamin B6 — 1.4 mg
Biotin — 50 µg

Frequently asked questions
How long before anything is visible?
Hair grows slowly, roughly a centimetre a month, and the follicle cycle is measured in months rather than weeks. Twelve weeks is the minimum sensible period over which to judge anything.
Is thinning hair the same as hair loss?
No. Hair can feel thinner because strands are finer, because they break sooner, or because fewer are growing. These are different situations. Persistent or sudden hair loss is a medical question and belongs with a healthcare professional, not with a supplement.
Why one capsule rather than a powder?
A capsule delivers a measured amount every time and protects the contents from air and moisture. We wrote about that choice here.
Can it be taken alongside your other formulas?
Yes. Hair Beautification™, Beauty Complete™ and Peak Performance Formula™ are formulated to work as a daily set without duplicating the same nutrients at excessive amounts.
