Every day, humans shed about 100 hairs from our head, but women can lose even more than that. Here’s why and how you can get it shinier and healthier.

Every day, humans shed about 100 hairs from our head, but women can lose even more than that. Here’s why and how you can get it shinier and healthier.

Your scalp has around 100,000 hair follicles, and every three years each of those follicles goes through a cycle of hair growth, with the hair resting and falling out, followed by growth of new hair.

Sometimes that pattern is disturbed, and either the hair doesn’t grow or it becomes finer, so women get thinning hair, hair loss and patches of baldness. Just over half of women suffer some hair loss and thinning as they age. In most cases it’s not noticeable, but for about 20 per cent of women the loss is more obvious and distressing.

“About 50 per cent of women in their 40s suffer some thinning. And now women are experiencing this problem in their 20s and 30s,” says trichologist David Salinger.

From sugar to diabetes and crash dieting, we look at six reasons behind female hair loss and thinning and what can help.

“The amount of sugar in our diet is having an effect on our hair, and hidden sugars are part of the problem,” says David. Sugar causes inflammation and leads to white blood cells attacking the cells that produce hair. “When a woman has a normal level of insulin, it facilitates the conversion of testosterone back to estrogen,” says trichologist Anthony Pearce. Female hormones promote hair growth while male hormones, like testosterone, can aggravate hair loss.

Reduce sugar intake by reading food labels carefully, and if sugar is one of the first three ingredients listed, choose an alternative product, as the sugar content will be too high. Choose products with 15 g of sugar or less per 100 g.


“If you are 10 to 30 kg overweight, that will bring metabolic disturbance and hair loss,” says Anthony. Similarly, losing weight with a diet that cuts out key food groups is also a factor in thinning hair. Hair is made of protein, so not getting enough protein can affect hair growth. Similarly, iron and zinc deficiency can be linked to hair loss.

“With crash diets, you may see temporary hair loss because your hair is always three months behind the rest of your body,” says Salinger.

Follow the Health Promotion Board’s “My Healthy Plate” guide to ensure you get enough protein and minerals for healthy hair growth.

Excessive sugar can lead to insulin resistance – Finnish studies found women with high sugar diets and insulin resistance had a higher risk of hair loss.

“Some birth control pills can trigger hair thinning because they have a male hormone influence,” explains David. Diane-35, Yaz and Yasmin have a weaker male hormone effect than some Pills. If you are taking the Pill and feel it is affecting your hair, speak to your GP about alternative birth control.


Our body releases a natural substance called nerve growth factor when we are stressed. This causes the nerves around the hair follicle to become agitated and inflamed and leads to diffuse hair loss.

“Stress also increases cortisone, a hormone released by the adrenal gland. It has a similar effect to male hormones and so leads to thinning,” says David.

“And with extreme stress women can develop alopecia areata – circular patches of baldness that crop up quite quickly, within a week of two.”
Last year, scientists at Columbia University Medical Centre in the US found 75 per cent of patients with moderate to severe alopecia areata saw hair regrowth improve after they were treated with a drug called ruxolitinib. The drug identifies the immune cells that cause the inflammation that damages the hair follicles.

Scarring alopecia is a common problem after menopause, mostly occurring along the front hair line and front sides of the scalp. Caused by a loss of female hormones it leads to white blood cells attacking and scarring hair follicles. Hormone replacement therapy can help. “Eyebrows can be affected too. You can’t see scars on the scalp, but you see a little redness or a small scale around the follicle,” says David. A specialist may also prescribe an amino acid called tyrosine or recommend steroids to treat scarring alopecia. For those experiencing fluctuating hormones, doctors may also recommend minoxidil, an over-the-counter drug.


There’s not a lot you can do about your genetics, but knowing if you are more prone to thinning hair or hair loss can encourage you to act when you notice your hair is changing.

“Genetics are a major factor and for a woman to have genetic thinning, she will inherit the genes from both parents,” says David. “And it can be that both parents have wonderful hair but their daughter gets genetic thinning.”

The good news is that advances are being made in treating hair loss and thinning. The latest aesthetic clinics use cutting-edge laser or stem cell treatments to stimulate the scalp and fortify hair from a cellular level. These are typically minimally- or non-invasive, with little to no downtime.
