You have not changed your routine, yet your hair looks thinner.

As menopause approaches, oestrogen levels begin to fall. That matters because hair follicles respond directly to oestrogen. They are not simply affected indirectly by everything else happening in the body (Ohnemus et al., Endocrine Reviews, 2006).

Oestrogen helps support the follicle during its active growth phase. As that hormonal support declines, some follicles may leave the growth phase sooner than they used to.

This is also a time when female-pattern hair loss becomes more common. The typical signs are a gradually widening parting and progressive thinning across the top of the scalp.

Genetics can influence how strongly this happens, which is why the experience varies so much from one woman to another.

It does not mean menopause automatically causes hair loss.

It means your hormonal history matters, and it is one important part of understanding what may be contributing to the change.

In the years before your periods stop, they often become heavier and harder to predict. That's worth knowing, because heavier bleeding draws down your iron stores month after month, and low iron is a recognised contributor to hair shedding.

The marker your GP uses is ferritin. Ask for it by name, and say the words “hair loss” when you do  it changes what gets tested and how the result is read. Bring it up alongside your thyroid, which is the other thing worth ruling out at this stage. Both are simple blood tests. Both are free.

Do this first. If low iron is what's driving your shedding, no serum on any shelf will fix it, and you'd be spending money on the wrong problem.

But here is what we hear from British women again and again: the bloods come back, everything sits inside the normal range, and the hair keeps thinning anyway.

That result isn't a dead end. It's information. It tells you the shedding isn't coming from a deficiency you can correct with tablets  which points you somewhere else entirely.

Not at the hair. At the follicle underneath it, and at what changed for that follicle when your oestrogen levels started to fall.

When hair changes and menopause happen at the same time, it is easy to assume one is causing the other.

But menopause is not always the whole story. Thyroid problems and low iron are two things a clinician may also consider, particularly in women during midlife.

Changes such as unusually dry, coarse hair or thinning at the outer edges of the eyebrows can sometimes be clues that something else is contributing.

So the better question is not, “Is this just my age?”

It is, “What is actually contributing to this, and what would address the cause?”

A conversation with your GP can help rule out underlying factors before you spend more money trying another product that may be targeting the wrong problem.

You’ve tried gummies, a thickening shampoo, perhaps even minoxidil. Yet your parting still looks wider than you’d like. It’s frustrating, but these products work in different ways.

Biotin deficiency can affect hair, but it is uncommon. Without a deficiency, there is little evidence that taking extra biotin improves hair growth.

Minoxidil is an evidence-based treatment for female pattern hair loss that acts on the follicles. It usually takes several months to assess, can cause temporary shedding or scalp irritation, and requires continued use to maintain its benefits.

Thickening shampoos can make existing strands look fuller. That cosmetic effect is useful, but it does not mean new hair is growing.

Supplements may help when a nutritional deficiency contributes to shedding. More ingredients, however, do not automatically mean better results.

The hair you can touch is no longer living tissue. The follicle beneath the skin produces it. Understanding whether you need cosmetic volume, correction of a deficiency or treatment for hair loss helps you choose a routine with realistic expectations.

Choosing a scalp serum starts with two questions: what’s in the formula, and how easily can you apply it where it belongs?

Peptides are short chains of amino acids. Some act as messengers between cells, and certain peptides are being studied for their potential role in supporting hair growth.

PDRN consists of purified DNA fragments, often derived from salmon. It has been studied in tissue repair and explored for hair growth, largely through injectable treatments. Research on topical use is still developing, so those findings cannot automatically be applied to a scalp serum.

Application matters too. A brush that parts the hair can help place the formula directly onto the scalp. Reaching the scalp’s surface, however, does not establish that ingredients reach the follicle or stimulate growth.

Meet KLYVER, a scalp serum formulated with PDRN and peptides, with a 38-bristle brush designed for targeted application. Its mineral micro-spicules may produce a tingling sensation, although tingling itself is not evidence of absorption or effectiveness.

Use it as directed as part of your cosmetic scalp-care routine. If you’re receiving treatment for a diagnosed cause of hair loss, continue following your clinician’s advice.

Take a photo of your parting before you begin. Use the same lighting and angle for future comparisons, and remember that visible changes take time and results vary.
