However, surprisingly, a recent study published in JAMA Dermatology found there’s no relationship between hair loss and testosterone levels in men.
If you want to maintain your head of hair for as long as possible, start to pay more attention to your daily grooming habits.
Jumping in and out of the shower as quickly as possible might mean more time in bed, but it could be speeding up you going bald.
That’s because taking the time to massage your head as you shampoo stimulates hair growth.
Ananbel Kingsley, trichologist at Philip Kingsley, said: “Scalp massage can be beneficial for those experiencing a gradual reduction in hair volume or hair loss.”
It does this by improving blood flow directly to the area, and by removing dead skin cells which have been proven to cause or worsen hair loss.
She explained: “It should ideally be done for five to ten minutes once to twice a week. It should be gentle yet firm with consistent pressure.
“Using both hands, gently knead your scalp in circular movements starting at the front hairline and gradually working your way back down to the nape of your neck.
“Repeat three to four times, then, with a gentle sweeping action, smooth your hands over the top of your scalp.”
Additionally, a study published in the International Journal of Neuroscience found that massaging your scalp also lowers hair loss-inducing stress levels.
However, Anabel added: “Scalp massage alone will not have a vast impact on hair growth. Its benefits are highly dependent on what is used during massage – try a stimulating scalp mask.
“Additionally, one of the most common causes of hair loss is the result of iron and ferritin – stored iron – deficiency.
“A healthy diet, eating adequate iron and proteins and taking care of your general health will help prevent both hair loss and hair thinning – and will often improve the general appearance of the hair.”
