Perimenopause can affect hair through hormonal changes. At the same time, low iron, vitamin D, zinc or protein intake can place additional pressure on the hair-growth cycle.
So, what happens when hormonal changes and nutritional gaps overlap?
What changes during perimenopause?
Perimenopause is the transition leading up to menopause. During this time, levels of oestrogen and other reproductive hormones can fluctuate.
Hair follicles become sensitive to hormonal changes. Research says, some perimenopausal women notice a significant increase in hair shedding and reduced hair density.

But hormones are not always the only factor.
Stress, thyroid conditions, rapid weight loss, restrictive diets and nutritional deficiencies can also contribute to hair shedding. Several factors can occur at the same time, which is why it is important to understand the cause before choosing a solution.
Two pressures on hair during perimenopause
During perimenopause, hair can face two changes at the same time.
First, fluctuating hormones can affect the hair-growth cycle. Hair can spend less time growing, leading to increased shedding, finer strands and reduced density.

Second, nutritional gaps can make it harder for follicles to produce healthy hair. Iron, vitamin D, zinc and protein all support normal hair growth, but low levels or an inconsistent diet can reduce the support available to the follicle.
This is where Cyclical Nutritional Therapy fits into the routine.
Which nutrients matter for hair health?
Hair is mostly made of keratin, a type of protein. Producing new hair also depends on a steady supply of energy, amino acids, vitamins and minerals.
Nutrients commonly discussed in relation to hair health include:
- Iron, which supports oxygen delivery to growing follicle cells
- Zinc, which supports cell division and normal protein production
- Vitamin D, which plays a role in follicle biology
- Protein, which provides the building blocks needed to produce keratin
Deficiencies in some of these nutrients have been associated with different forms of hair loss.
Where does Cyclical Nutritional Therapy fit?
Cyclical Nutritional Therapy sequences hair-supporting nutrients, vitamins and botanical ingredients into a planned six-day routine.
Each day has a different nutritional focus, followed by a break on Sunday. This removes the need to create and manage several supplement combinations on your own.

NOURRIR Hair Health Supplements follow this Monday-to-Saturday structure, with day-labelled tablets that make the routine straightforward to follow.
The approach is designed to support different areas of hair health, including follicle nutrition, scalp health, hair structure and antioxidant defence.
A structured routine can make supplementation simpler, but it should not be confused with treating every cause of perimenopausal hair loss.
