As many as one in three women over the age of 25 suffer from hair loss as a result of stress, according to research.

Some 37 per cent of women have experienced thinning hair and serious hair loss affects 4.8 million women across the UK. Experts have revealed that women may be eating less to try to lose weight, which leads to poor nutrition and hair loss.

The hair loss itself can then lead to higher stress levels which accelerates the problem. Of those who suffer from hair loss, a third said their hair loss made them depressed while 25 per cent said the personal lives had been affected by their thinning hair.

Thrichologist, Sara Allison explains the problem, “we are all leading more emotionally stressful lives and are more nutritionally deficient than previous generations.

She added, “the pressure on women to stay thin often means that they simply don't eat enough to get all the nutrients or they are not eating the right foods."

"Hair is essentially the least important tissue of your body; therefore, your hair only receives nutrients if there are any remaining in the body after your vital organs have taken what they need."
